     FIELD OF THE INVENTION  
      The present invention relates generally to a chewing gum composition comprising a high-potency sweetener composition with improved temporal profile and/or flavor profile.  
     BACKGROUND OF THE INVENTION  
      Natural caloric sugars, such as sucrose, fructose, and glucose are utilized heavily in beverage, food, pharmaceutical, and oral hygienic/cosmetic industries due to their pleasant taste. In particular, sucrose imparts a desirable taste for consumers. Although sucrose provides superior sweetness characteristics, it is caloric. While calories are necessary for proper bodily functions, there is a need in the market to provide alternative non-caloric or low-caloric sweeteners with sugar-like taste for consumers with sedentary lifestyles or those who are calorie conscious. However, in general, non-caloric or low caloric sweeteners have associated undesirable tastes to consumers such as delayed sweetness onset; lingering sweet aftertaste; bitter taste; metallic taste; astringent taste; cooling taste; licorice-like taste; and/or the like.  
      For example, the sweet tastes of natural and/or synthetic high-potency sweeteners are slower in onset and longer in duration than the sweet taste produced by sugar and thus change the taste balance of a food composition. Because of these differences, use of a natural high-potency sweetener to replace a bulk sweetener, such as sugar, in a food or beverage, causes an unbalanced temporal profile and/or flavor profile. In addition to the difference in temporal profile, high-potency sweeteners generally exhibit (i) lower maximal response than sugar, (ii) off tastes including bitter, metallic, cooling, astringent, licorice-like taste, etc., and/or (iii) sweetness which diminishes on iterative tasting. It is well known to those skilled in the art of food/beverage formulation that changing the sweetener in a composition requires re-balancing of the flavor and other taste components (e.g., acidulants). If the taste profile of natural and synthetic high-potency sweeteners could be modified to impart specific desired taste characteristics to be more sugar-like, the type and variety of compositions that may be prepared with that sweetener would be significantly expanded. Accordingly, it would be desirable to selectively modify the taste characteristics of natural and synthetic high-potency sweeteners.  
     SUMMARY OF THE INVENTION  
      Generally, this invention addresses the above described need by providing a chewing gum composition having improved temporal profile and/or flavor profile and a method for improving the temporal profile and/or flavor profile for chewing gum compositions. In particular, this invention improves the temporal profile and/or flavor profile by imparting a more sugar-like temporal profile and/or flavor profile. More particularly, this invention comprises a chewing gum composition comprising a gum base; at least one high-potency sweetener; and at least one sweet taste improving composition.  
      Objects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention. Unless otherwise defined, all technical and scientific terms and abbreviations used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Although methods and compositions similar or equivalent to those described herein can be used in practice of the present invention, suitable methods and compositions are described without intending that any such methods and compositions limit the invention herein.

     DETAILED DESCRIPTION OF THE INVENTION  
      Reference now will be made in detail to the presently proffered embodiments of the invention. Each example is provided by way of explanation of embodiments of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. For instance, features illustrated or described as part of one embodiment, can be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention cover such modifications and variations within the scope of the appended claims and their equivalents.  
      Generally described, embodiments of the present invention provide chewing gum compositions comprising at least one natural and/or synthetic high-potency sweetener, at least one sweet taste improving composition, and a gum base.  
      I. Chewing Gum Compositions  
      Chewing gum compositions generally comprise a water-soluble portion and a water-insoluble chewable gum base portion. The water soluble portion, which typically includes the at least one natural and/or synthetic high-potency sweetener and the at least one sweet taste improving composition, dissipates with a portion of the flavoring agent over a period of time during chewing while the insoluble gum base portion is retained in the mouth. The insoluble gum base generally determines whether a gum is considered chewing gum, bubble gum, or a functional gum.  
      The insoluble gum base, which is generally present in the chewing gum composition in an amount in the range of about 15 to about 35 weight percent of the chewing gum composition, generally comprises combinations of elastomers, softeners (plasticizers), emulsifiers, resins, and fillers. Such components generally are considered food grade, recognized as safe (GRA), and/or are U.S. Food and Drug Administration (FDA)-approved.  
      Elastomers, the primary component of the gum base, provide the rubbery, cohesive nature to gums and can include one or more natural rubbers (e.g., smoked latex, liquid latex, or guayule); natural gums (e.g., jelutong, perillo, sorva, massaranduba balata, massaranduba chocolate, nispero, rosindinha, chicle, and gutta hang kang); or synthetic elastomers (e.g., butadiene-styrene copolymers, isobutylene-isoprene copolymers, polybutadiene, polyisobutylene, and vinyl polymeric elastomers). In a particular embodiment, the elastomer is present in the gum base in an amount in the range of about 3 to about 50 weight percent of the gum base.  
      Resins are used to vary the firmness of the gum base and aid in softening the elastomer component of the gum base. Non-limiting examples of suitable resins include a rosin ester, a terpene resin (e.g., a terpene resin from α-pinene, β-pinene and/or d-limonene), polyvinyl acetate, polyvinyl alcohol, ethylene vinyl acetate, and vinyl acetate-vinyl laurate copolymers. Non-limiting examples of rosin esters include a glycerol ester of a partially hydrogenated rosin, a glycerol ester of a polymerized rosin, a glycerol ester of a partially dimerized rosin, a glycerol ester of rosin, a pentaerythritol ester of a partially hydrogenated rosin, a methyl ester of rosin, or a methyl ester of a partially hydrogenated rosin. In a particular embodiment, the resin is present in the gum base in an amount in the range of about 5 to about 75 weight percent of the gum base.  
      Softeners, which also are known as plasticizers, are used to modify the ease of chewing and/or mouthfeel of the chewing gum composition. Generally, softeners comprise oils, fats, waxes, and emulsifiers. Non-limiting examples of oils and fats include tallow, hydrogenated tallow, large, hydrogenated or partially hydrogenated vegetable oils (e.g., soybean, canola, cottonseed, sunflowers palm, coconut, corn, safflower, or palm kernel oils), cocoa butter, glycerol monostearate, glycerol triacetate, glycerol abietate, leithin, monoglycerides, diglycerides, triglycerides acetylated monoglycerides, and free fatty acids. Non-limiting examples of waxes include polypropylene/polyethylene/Fisher-Tropsch waxes, paraffin, and microcrystalline and natural waxes (e.g., candelilla, beeswas and carnauba). Microcrystalline waxes, especially those with a high degree of crystallinity and a high melting point, also may be considered as bodying agents or textural modifiers. In a particular embodiment, the softeners are present in the gum base in an amount in the range of about 0.5 to about 25 weight percent of the gum base.  
      Emulsifiers are used to form a uniform dispersion of the insoluble and soluble phases of the chewing gum composition and also have plasticizing properties. Suitable emulsifiers include glycerol monostearate (GMS), lecithin (Phosphatidyl choline), polyglycerol polyricinoleic acid (PPGR), mono and diglycerides of fatty acids, glycerol distearate, tracetin, acetylated monoglyceride, glycerol triactetate, and magnesium stearate. In a particular embodiment, the emulsifiers are present in the gum base in an amount in the range of about 2 to about 30 weight percent of the gum base.  
      The chewing gum composition also may comprise adjuvants or fillers in either the gum base and/or the soluble portion of the chewing gum composition. Suitable adjuvants and fillers include lecithin, inulin, polydextrin, calcium carbonate, magnesium carbonate, magnesium silicate, ground limestome, aluminum hydroxide, aluminum silicate, talc, clay, alumina, titanium dioxide, and calcium phosphate. In particular embodiments, lecithin can be used as an inert filler to decrease the stickiness of the chewing gum composition. In other particular embodiments, lactic acid copolymers, proteins (e.g., gluten and/or zein) and/or guar can be used to create a gum that is more readily biodegradable. The adjuvants or fillers are generally present in the gum base in an amount up to about 20 weight percent of the gum base. Other optional ingredients include coloring agents, whiteners, preservatives, and flavors.  
      In particular embodiments of the chewing gum composition, the gum base comprises about 5 to about 95 weight percent of the chewing gum composition, more desirably about 15 to about 50 weight percent of the chewing gum composition, and even more desirably from about 20 to about 30 weight percent of the chewing gum composition.  
      The soluble portion of the chewing gum composition may optionally include other artificial or natural sweeteners, bulk sweeteners, softeners, emulsifiers, flavoring agents, coloring agents, adjuvants, fillers, functional agents (e.g., pharmaceutical agents or nutrients), or combinations thereof. Suitable examples of softeners and emulsifiers are described above.  
      Bulk sweeteners include both caloric and non-caloric compounds. In a particular embodiment, the sweet taste improving composition functions as the bulk sweetener. Non-limiting examples of bulk sweeteners include sucrose, dextrose, maltose, dextrin, dried invert sugar, fructose, high fructose corn syrup, levulose, galactose, corn syrup solids, tagatose, polyols (e.g., sorbitol, mannitol, xylitol, lactitol, erytlritol, and maltitol), hydrogenated starch hydrolysates, isomalt, trehalose, and mixtures thereof. In particular embodiments, the bulk sweetener is present in the chewing gum composition in an amount in the range of about 1 to about 75 weight percent of the chewing gum composition.  
      Flavoring agents may be used in either the insoluble gum base or soluble portion of the chewing gum composition. Such flavoring agents may be natural or artificial flavors. In a particular embodiment, the flavoring agent comprises an essential oil, such as an oil derived from a plant or a fruit, peppermint oil, spearmint oil, other mint oils, clove oil, cinnamon oil, oil of wintergreen, bay , thyme, cedar leaf, nutmeg, allspice, sage, mace, and almonds. In another particular embodiment, the flavoring agent comprises a plant extract or a fruit essence such as apple, banana, watermelon, pear, peach, grape, strawberry, raspberry, cherry, plum, pineapple, apricot, and mixtures thereof. In still another particular embodiment, the flavoring agent comprises a citrus flavor, such as an extract, essence, or oil of lemon, lime, orange, tangerine, grapefruit, citron, or kumquat.  
      In a particular embodiment, a chewing gum composition comprises at least one natural and/or synthetic high-potency sweetener in combination with at least one sweet taste improving composition and a gum base. In a particular embodiment, the at least one natural and/or synthetic high-potency sweetener is present in the chewing gum composition in an amount in the range of about 200 ppm to about 20,000 ppm of the chewing gum composition.  
      II. Sweetener Compositions  
      As described hereinabove, the chewing gum compositions comprise at least one natural and/or synthetic high-potency sweetener and at least one sweet taste improving composition. The combination of the at least one natural and/or synthetic high-potency sweetener and at least one sweet taste improving composition, as used herein, comprises the “sweetener composition.” As used herein, a gum base is synonymous with a “sweetenable composition.” In addition, the combination of the sweetener composition and a gum base comprises a “sweetened composition.” 
      A. Natural High-Potency Sweeteners  
      Desirably, the sweetener composition comprises at least one natural and/or synthetic high-potency sweetener. As used herein the phrases “natural high-potency sweetener”, “NHPS”, “NHPS composition”, and “natural high-potency sweetener composition” are synonymous. “NHPS” means any sweetener found in nature which may be in raw, extracted, purified, or any other form, singularly or in combination thereof and characteristically have a sweetness potency greater than sucrose, fructose, or glucose, yet have less calories. Non-limiting examples of NHPSs suitable for embodiments of this invention include rebaudioside A, rebaudioside B, rebaudioside C, rebaudioside D, rebaudioside E, rebaudioside F, dulcoside A, dulcoside B, rubusoside, stevia, stevioside, mogroside IV, mogroside V, Luo Han Quo sweetener, siamenoside, monatin and its salts (monatin SS, RR, RS, SR), curculin, glycyrrhizic acid and its salts, thaumatin, monellin, mabinlin, brazzein, hemandulcin, phyllodulcin, glycyphyllin, phloridzin, trilobatin, baiyunoside, osladin, polypodoside A, pterocaryoside A, pterocaryoside B, mukurozioside, phlomisoside I, periandrin I, abrusoside A, and cyclocarioside I. NHPS also includes modified NHPSs. Modified NHPSs include NHPSs which have been altered naturally. For example, a modified NHPS includes, but is not limited to, NHPSs which have been fermented, contacted with enzyme, or derivatized or substituted on the NHPS. In one embodiment, at least one modified NHPS may be used in combination with at least one NHPS. In another embodiment, at least one modified NHPS may be used without a NHPS. Thus, modified NHPSs may be substituted for a NHPS or may be used in combination with NHPSs for any of the embodiments described herein. For the sake of brevity, however, in the description of embodiments of this invention, a modified NHPS is not expressly described as an alternative to an unmodified NHPS, but it should be understood that modified NHPSs can be substituted for NHPSs in any embodiment disclosed herein.  
      In one embodiment, extracts of a NHPS may be used in any purity percentage. In another embodiment, when a NTHPS is used as a non-extract, the purity of the NHPS may range for example from about 25% to about 100%. According to other embodiments, the purity of the NHPS may range from about 50% to about 100% from about 70% to about 100%; from about 80% to about 100%; from about 90% to about 100%; from about 95% to about 100%; from about 95% to about 99.5%; from about 96% to about 100%; from about 97% to about 100%; from about 98% to about 100%; and from about 99% to about 100%.  
      Purity, as used here, represents the weight percentage of a respective NHPS compound present in a NHPS extract, in raw or purified form. In one embodiment, a steviolglycoside extract comprises a particular steviolglycoside in a particular purity, with the remainder of the stevioglycoside extract comprising a mixture of other steviolglycosides.  
      To obtain a particularly pure extract of a NHPS, such as rebaudioside A, it may be necessary to purify the crude extract to a substantially pure form. Such methods generally are known to those of ordinary skill in the art.  
      An exemplary method for purifying a NHPS, such as rebaudioside A, is described in the co-pending patent application No. 60/805,216, entitled “Rebaudioside A Composition and Method for Purifying Rebaudioside A,” filed on Jun. 19, 2006, by inventors DuBois, et al., the disclosure of which is incorporated herein by reference in its entirety.  
      Briefly described, substantially pure rebaudioside A is crystallized in a single step from an aqueous organic solution comprising at least one organic solvent and water in an amount from about 10% to about 25% by weight, more particularly from about 15% to about 20% by weight. Organic solvents desirably comprise alcohols, acetone, and acetonitile. Non-limiting examples of alcohols include ethanol, methanol, isopranol, 1-propanol, 1-butanol, 2-butanol, tert-butanol, and isobutanol. Desirably, the at least one organic solvent comprises a mixture of ethanol and methanol present in the aqueous organic solution in a weight ratio ranging from about 20 parts to about 1 part ethanol to 1 part methanol, more desirably from about 3 parts to about 1 part ethanol to 1 part methanol.  
      Desirably, the weight ratio of the aqueous organic solvent and crude rebaudioside A ranges from about 10 to about 4 parts aqueous organic solvent to 1 part crude rebaudioside A, more particularly from about 5 to about 3 parts aqueous organic solvent to 1 part crude rebaudioside A.  
      In an exemplary embodiment, the method of purifying rebaudioside A is carried out at approximately room temperature. In another embodiment, the method of purifying rebaudioside A further comprises the step of heating the rebaudioside A solution to a temperature in a range from about 20° C. to about 40° C., or in another embodiment to a reflux temperature, for about 0.25 hours to about 8 hours. In another exemplary embodiment, wherein the method for purifying rebaudioside A comprises the step of heating the rebaudioside A solution, the method further comprises the step of cooling the rebaudioside A solution to a temperature in the range from about 4° C. to about 25° C. for about 0.5 hours to about 24 hours.  
      According to particular embodiments, the purity of rebaudioside A may range from about 50% to about 100%; from about 70% to about 100%; from about 80% to about 100%; from about 90% to about 100%; from about 95% to about 100%; from about 95% to about 99.5%; about 96% to about 100%; from about 97% to about 100%; from about 98% to about 100%; and from about 99% to about 100%. According to particularly desirable embodiments, upon crystallization of crude rebaudioside A, the substantially pure rebaudioside A composition comprises rebaudioside A in a purity greater than about 95% by weight up to about 100% by weight on a dry basis. In other exemplary embodiments, substantially pure rebaudioside A comprises purity levels of rebaudioside A greater than about 97% up to about 100% rebaudioside A by weight on a dry basis, greater than about 98% up to about 100% by weight on a dry basis, or greater than about 99% up to about 100% by weight on a dry basis. The rebaudioside A solution during the single crystallization step may be stirred or unstirred.  
      In an exemplary embodiment, the method of purifying rebaudioside A further comprises the step of seeding (optional step) the rebaudioside A solution at an appropriate temperature with high-purity crystals of rebaudioside A sufficient to promote crystallization of the rebaudioside A to form pure rebaudioside A. An amount of rebaudioside A sufficient to promote crystallization of substantially pure rebaudioside A comprises an amount of rebaudioside A from about 0.0001% to about 1% by weight of the rebaudioside A present in the solution, more particularly from about 0.01% to about 1% by weight. An appropriate temperature for the step of seeding comprises a temperature in a range from about 18° C. to about 35° C.  
      In another exemplary embodiment, the method of purifying rebaudioside A further comprises the steps of separating and washing the substantially pure rebaudioside A composition. The substantially pure rebaudioside A composition may be separated from the aqueous organic solution by a variety of solid-liquid separation techniques that utilize centrifugal force, that include, without limitation, vertical and horizontal perforated basket centrifuge, solid bowl centrifuge, decanter centrifuge, peeler type centrifuge, pusher type centrifuge, Heinkel type centrifuge, disc stack centrifuge and cyclone separation. Additionally, separation may be enhanced by any of pressure, vacuum, and gravity filtration methods, that include, without limitation, the use of belt, drum, nutsche type, leaf, plate. Rosenmund type, sparkler type, and bag filters and filter press. Operation of the rebaudioside A solid-liquid separation device may be continuous, semi-continuous or in batch node. The substantially pure rebaudioside A composition also may be washed on the separation device using various aqueous organic solvents and mixtures thereof. The substantially pure rebaudioside A composition can be dried partially or totally on the separation device using any number of gases, including, without limitation, nitrogen and argon, to evaporate residual liquid solvent. The substantially pure rebaudioside A composition may be removed automatically or manually from the separation device using liquids, gases or mechanical means by either dissolving the solid or maintaining the solid form.  
      In still another exemplary embodiment, the method of purifying rebaudioside A further comprises the step of drying the substantially pure rebaudioside A composition using techniques well known to those skilled in the art, non-limiting examples of which include the use of a rotary vacuum dryer, fluid bed dryer, rotary tunnel dryer, plate dryer, tray dryer, Nauta type dryer, spray dryer, flash dryer, micron dryer, pan dryer, high and low speed paddle dryer and microwave dryer. In an exemplary embodiment, the step of drying comprises drying the substantially pure rebaudioside A composition using a nitrogen or argon purge to remove the residual solvent at a temperature in a range from about 40° C. to about 60° C. for about 5 hours to about 100 hours.  
      In yet another exemplary embodiment, wherein the crude rebaudioside A mixture comprises substantially no rebaudioside D impurity, the method of purifying rebaudioside A further comprises the step of slurrying the composition of substantially pure rebaudioside A with an aqueous organic solvent prior to the step of drying the substantially pure rebaudioside A composition. The slurry is a mixture comprising a solid and an aqueous organic or organic solvent, wherein the solid comprises the substantially pure rebaudioside A composition and is only sparingly soluble in the aqueous organic or organic solvent. In an embodiment, the substantially pure rebaudioside A composition and aqueous organic solvent are present in the slurry in a weight ratio ranging from about 15 parts to 1 part aqueous organic solvent to 1 part substantially pure rebaudioside A composition. In one embodiment, the slurry is maintained at room temperature. In another embodiment, the step of slurrying comprises heating the slurry to a temperature in a range from about 20 to about 40° C. The substantially pure rebaudioside A composition is slurried for about 0.5 hours to about 24 hours.  
      In still yet another exemplary embodiment, the method of purifying rebaudioside A further comprises the steps of separating the substantially pure rebaudioside A composition from the aqueous organic or organic solvent of the slurry and washing the substantially pure rebaudioside A composition followed by the step of drying the substantially pure rebaudioside A composition.  
      If further purification is desired, the method of purifying rebaudioside A described herein may be repeated or the substantially pure rebaudioside A composition may be purified further using an alternative purification method, such as the column chromatography.  
      It also is contemplated that other NHPSs may be purified using the purification method described herein, requiring only minor experimentation that would be obvious to those of ordinary skill in the art.  
      The purification of rebaudioside A by crystallization as described above results in the formation of at least three different polymorphs: Form 1 a rebaudioside A hydrate; Form 2: an anhydrous rebaudioside A; and Form 3: a rebaudioside A solvate. In addition to the at least three polymorph forms of rebaudioside A, the purification of rebaudioside A may result in the formation of an amorphous form of rebaudioside A, Form 4. The aqueous organic solution and temperature of the purification process influence the resulting polymorph and amorphous forms in the substantially pure rebaudioside A composition.  FIGS. 1-5  are exemplary powder x-ray diffraction (XRPD) scans of the polymorph and amorphous forms of rebaudioside A: Form 1 (hydrate), Form 2 (anhydrate), Form 3A (methanol solvate), Form 3B (ethanol solvate), and Form 4 (amorphous), respectively.  
      The material properties of the three rebaudioside A polymorphs and amorphous forms are summarized in the following table:  
               TABLE 1                          Rebaudioside A Polymorph and Amorphous Forms                                     Form 1   Form 2   Form 3   Form 4           Polymorph   Polymorph   Polymorph   Amorphous               Rate of dissolution   Very low   Intermediate   High   High       in H2O at 25° C.   (&lt;0.2%/60   (&lt;30%/5   (&gt;30%/5   (&gt;35.0%/5           minutes)   minutes)   minutes)   minutes)       Alcohol content   &lt;0.5%   &lt;1%   1-3%    &lt;0.05%       Moisture content   &gt;5%     &lt;1%   &lt;3%    6.74%                  
 
      The type of polymorph formed is dependent on the composition of the aqueous organic solution, the temperature of the crystallization step, and the temperature during the drying step. Form 1 and Form 3 are formed during the single crystallization step while Form 2 is formed during the drying step after conversion from Form 1 or Form 3.  
      Low temperatures during the crystallization step, in the range of about 20° C. to about 50° C., and a low ratio of water to the organic solvent in the aqueous organic solvent results in the formation of Form 3. High temperatures during the crystallization step, in the range of about 50° C. to about 80° C., and a high ratio of water to the organic solvent in the aqueous organic solvent results in the formation of the Form 1. Form 1 can be converted to Form 3 by slurrying in an anhydrous solvent at room temperature (2-16 hours) or at reflux for approximately (0.5-3 hours). Form 3 can be converted to Form 1 by slurrying the polymorph in water at room temperature for approximately 16 hours or at reflux for approximately 2-3 hours. Form 3 can be converted to the Form 2 during the drying process; however, increasing either the drying temperature above 70° C. or the drying time of a substantially pure rebaudioside A composition can result in decomposition of the rebaudioside A and increase the remaining rebaudioside B impurity in the substantially pure rebaudioside A composition. Form 2 can be converted to Form 1 with the addition of water.  
      Form 4 may be formed from Form 1, 2, 3, or combinations thereof, using methods well known to those of ordinary skill in the art. Non-limiting examples of such methods include melt-processing, ball milling, crystallization, lyophilization, cryo-grinding, and spray-drying. In a particular embodiment, Form 4 can be prepared from a substantially pure rebaudioside A composition obtained by the purification methods described hereinabove by spray-drying a solution of the substantially pure rebaudioside A composition.  
      B. Synthetic High-Potency Sweeteners  
      As used herein, the phrase “synthetic sweetener” refers to any compositions which are not found in nature and characteristically have a sweetness potency greater than sucrose, fructose, or glucose, yet have less calories. Non-limiting examples of synthetic sweeteners suitable for embodiments of this invention include sucralose, potassium acesulfame, aspartame, alitame, saccharin, neohesperidin dihydrochalcone, cyclamate, neotame, N-[N-[3-(3-hydroxy-4-methoxyphenyl)propyl]-L-α-aspartyl]-L-phenylalanine 1-methyl ester, N-[N-[3-(3-hydroxy-4-methoxyphenyl)-3-methylbutyl]-L-α-aspartyl]-L-phenylalanine 1-methyl ester, N-[N-[3-(3-methoxy-4-hydroxyphenyl)propyl]-L-α-aspartyl]-L-phenylalanine 1-methyl ester, salts thereof, and the like.  
      C. Combinations of Natural and/or Synthetic High-Potency Sweeteners  
      The NHPS and synthetic sweeteners may be used individually or in combination with other NHPS and/or synthetic sweeteners. For example, the sweetener composition may comprise a single NHPS or a single synthetic sweetener; a single NHPS in combination with a single synthetic sweetener; one or more NHPSs in combination with a single synthetic sweetener; a single NHPS in combination with one or more synthetic sweeteners; or one or more NHPSs in combination with one or more synthetic sweeteners. A plurality of natural and/or synthetic high-potency sweeteners may be used as long as the combined effect does not adversely affect the taste of the sweetener composition.

      III. Sweet Taste Improving Compositions  
      The sweetener composition also comprises a sweet taste improving composition, non-limiting examples of which include carbohydrates, polyols, amino acids and their corresponding salts, polyamino acids and their corresponding salts, sugar acids and their corresponding salts, nucleotides, organic acids, inorganic acids, organic salts including organic acid salts and organic base salts, inorganic salts, bitter compounds, flavorants and flavoring ingredients, astringent compounds, proteins or protein hydrolysates, surfactants, emulsifiers, flavonoids, alcohols, polymers, other sweet taste improving taste additives imparting such sugar-like characteristics, and combinations thereof.  
      In one embodiment, a single sweet taste improving composition may he used in combination with a single natural and/or synthetic high-potency sweetener. In another embodiment of the present invention, a single sweet taste improving composition may be used in combination with one or more natural and/or synthetic high-potency sweeteners. In yet another embodiment one or more sweet taste improving compositions may be used in combination with a single natural and/or synthetic high-potency sweetener. In a further embodiment, there may be a plurality of sweet taste improving combinations used in combination with one or more natural and/or synthetic high-potency sweeteners.  
      In a particular embodiment, combinations of at least one natural and/or synthetic high-potency sweetener and at least one sweet taste improving composition suppress, reduce, or eliminate undesirable taste and impart sugar-like characteristics to the sweetener composition. As used herein, the phrase “undesirable taste” includes any taste property which is not imparted by sugars, e.g. glucose, sucrose, fructose, or similar saccharides. Non-limiting examples of undesirable tastes include delayed sweetness onset, lingering sweet aftertaste, metallic taste, bitter taste, cooling sensation taste or menthol-like taste, licorice-like taste, and/or the like.  
      A. Sweet Taste  
      In one embodiment, a sweetener composition exhibits a more sugar-like temporal and/or sugar-like flavor profile than a sweetener composition comprising at least one natural and/or synthetic high-potency sweetener, but without a sweet taste improving composition is provided. As used herein, the phrases “sugar-like characteristic,” “sugar-like taste,” “sugar-like sweet,” “sugary,” and “sugar-like” are synonymous. Sugar-like characteristics include any characteristic similar to that of sucrose and include, but are not limited to, maximal response, flavor profile, temporal profile, adaptation behavior, mouthfeel, concentration/response function behavior, tastant and flavor/sweet taste interactions, spatial pattern selectivity, and temperature effects. These characteristics are dimensions in which the taste of sucrose is different from the tastes of natural and synthetic high-potency sweeteners. Whether or not a characteristic is more sugar-like is determined by expert sensory panel assessments of sugar and compositions comprising at least one natural and/or synthetic high-potency sweetener, both with and without a sweet taste improving composition. Such assessments quantify similarities of the characteristics of compositions comprising at least one natural and/or synthetic high-potency sweetener, both with and without a sweet taste improving composition, with those comprising sugar. Suitable procedures for determining whether a composition has a more sugar-like taste are well known in the art.  
      In a particular embodiment, a panel of assessors is used to measure the reduction of sweetness linger. Briefly described, a panel of assessors (generally 8 to 12 individuals) is trained to evaluate sweetness perception and measure sweetness at several time points from when the sample is initially taken into the mouth until 3 minutes after it has been expectorated. Using statistical analysis, the results are compared between samples containing additives and samples that do not contain additives. A decrease in score for a time point measured after the sample has cleared the mouth indicates there has been a reduction in sweetness perception.  
      The panel of assessors may be trained using procedures well known to those of ordinary skill in the art. In a particular embodiment, the panel of assessors may be trained using the Spectrum™ Descriptive Analysis Method (Meilgaard et al,  Sensory Evaluation Techniques , 3 rd  edition, Chapter 11). Desirably, the focus of training should be the recognition of and the measure of the basic tastes; specifically, sweet. In order to ensure accuracy and reproducibility of results, each assessor should repeat the measure of the reduction of sweetness linger about three to about five times per sample, taking at least a five minute break between each repetition and/or sample and rinsing well with water to clear the mouth.  
      Generally, the method of measuring sweetness comprises taking a 10 mL sample into the mouth, holding the sample in the mouth for 5 seconds and gently swirling the sample in the mouth, rating the sweetness intensity perceived at 5 seconds, expectorating the sample (without swallowing following expectorating the sample), rinsing with one mouthful of water (e.g., vigorously moving water in mouth as if with mouth wash) and expectorating the rinse water, rating the sweetness intensity perceived immediately upon expectorating the rinse water, waiting 45 seconds and, while waiting those 45 seconds, identifying the time of maximum perceived sweetness intensity and rating the sweetness intensity at that time (moving the mouth normally and swallowing as needed), rating the sweetness intensity after another 10 seconds, rating the sweetness intensity after another 60 seconds (cumulative 120 seconds after rinse), and rating the sweetness intensity after still another 60 seconds (cumulative 180 seconds after rinse). Between samples take a 5 minute break, rinsing well with water to clear the mouth.

      It is contemplated that the combination of at least one natural and/or synthetic high-potency sweetener to at least one sweet taste improving composition may be carried out in any pH range that does not materially or adversely affect the taste of the sweetener composition. A non-limiting example of the pH range may be from about 2 to about 8. A further example includes a pH range from about 2 to about 5.  
      One of ordinary skill in the art may combine at least one natural and/or synthetic high-potency sweetener, at least one sweet taste improving composition, and sweetenable composition in any manner. For example, at least one natural and/or synthetic high-potency sweetener may be added to the sweetenable composition before the at least one sweet taste improving composition.

In yet another example, at least one natural and/or synthetic high-potency sweetener may be added to the sweetenable composition simultaneously with the at least one sweet taste improving composition.  
      In yet another embodiment, at least one natural and/or synthetic high-potency sweetener may be combined with the at least one sweet taste improving composition prior to being added to a sweetenable composition. For example, the at least one natural and/or synthetic high-potency sweetener may be in a pure, diluted, or concentrated form as a liquid (e.g., solution), solid (e.g., powder, chunk, pellet, grain, block, crystalline, or the like), suspension, gas state, or combinations thereof may be contacted with the at least one sweet taste improving composition which may be in a pure, diluted, or concentrated form as a liquid (e.g., solution), solid (e.g., powder, chunk, pellet, grain, block, crystalline, or the like), suspension, gas state, or combinations thereof before both are contacted with a sweetenable composition. In yet another embodiment, when there are more than one natural and/or synthetic high-potency sweeteners or more than one sweet taste improving composition in the sweetenable composition, each component of the sweetenable composition may be added simultaneously, in an alternating pattern, in a random pattern, or any other pattern.

      VI. Methods of Making Chewing Gum Compositions  
      Suitable chewing gum compositions and methods of making such compositions are well known to those of ordinary skill in the art. For example, the chewing gum compositions may be formulated to extend flavor, control sweetness release, or improve the stability of the sweetener.  
      Generally, chewing gum is manufactured by sequentially adding the various chewing gum ingredients to a commercially available mixer known in the art. After the ingredients have been mixed thoroughly, the gum mass is discharged from the mixer and shaped into the desired form. For example, the gun mass may be rolled into sheets and cut into sticks, extruded into chunks, or cast into pellets or tablets. The chewing gum composition may take the form of a variety of different shapes, non-limiting examples of which include sticks, chunks, tablets, center filled, balls, fruit shapes, coins, tube gums, and compressed powder gums. Corn starch or talc can be used to dust chewing gum products prior to packaging.  
      The ingredients generally are mixed by first melting the gum base and adding it to the running mixer. The gum base also may be melted in the mixer itself. Color or emulsifiers also may be added at this time. A softener can be added next along with the syrup and a portion of the bulking agent. Further portions of the bulking agents then can be added to the mixer. In particular embodiments, flavoring agents are added to the gum mixture near the end of the mixing process. Such methods may be carried out in a continuous or batch-wise fashion.  
      In particular embodiments comprising a outer layer and inner core, any conventional manufacturing process that may be used to concentrically form the product may be used. For example, a double feed extruder having two concentrically aligned delivery tubes may be used. In another embodiment, a batch roller system comprising an inner extrusion tube surrounded by longitudinally placed rollers may be used. In such embodiments, the pliable confection is fed to the outer surface area of the inner tube where it is drawn and thinned by rollers around the tube, forming a rope comprising the outer layer and inner core. The rope is cooled, sized, and cut into the desired shape for packaging. These methods may be used to form chewing gum compositions having hard outer shells with chewing gum cores or outer gum shells with liquid fill cores.  
      In a particular embodiment, one or more of the components of the chewing gum composition described hereinabove may be encapsulated. Desirably, the natural and/or synthetic high-potency sweetener and sweet taste improving compositions are encapsulated, thereby enhancing the up front sweetness intensity, prolonging the sweetness duration, and improving the protection and stability of the natural and/or synthetic high-potency sweetener. Methods of encapsulating these components are well known to those skilled in the art and described in U.S. Pat. No. 5,064,658.  
      The particular materials and methods of encapsulation will afford different degrees of protection, thereby resulting in different levels of shelf-life stability enhancement. The preferred quantity and type of encapsulating or other material employed to protect the natural and/or synthetic high-potency sweetener from interacting with other chewing gum components may be specifically tailored depending upon a variety of factors including, but not limited to, the encapsulation or other method employed to form said admixture, the type of encapsulant or material agent used to form said admixture, and the amount of encapsulant or other material agent used to form said admixture. Since the level of protection may be governed by a number of factors such as cost, desired stability enhancement, and degree of processing conditions, it is contemplated that those skilled in the art will recognize the various factors and make the adjustments necessary to achieve the desired level of stability enhancement.  
      In a particular embodiment, the chewing gum composition comprises a gum base and an encapsulated sweetener composition comprising at least one natural and/or synthetic high-potency sweetener and at least one sweet-taste improving composition surrounded by a coating layer. The coating layer may comprise a combination of a polymer, such as a low molecular weight polyvinyl acetate, and an emulsifier.  
      As previously noted, encapsulation techniques are well known to those of ordinary skill in the art. Briefly described, encapsulation of components, such as the natural and/or synthetic high-potency sweetener and sweet taste improving composition, may be achieved by first dissolving the desired components in a solvent and homogenously mixing the solution with a resin (e.g., polyvinyl acetate) using any suitable mixer. The resin optionally may be heated to aid mixing. Following mixing, the homogenous mixture is dried to remove the solvent using any suitable method. The dried mixture is sized by methods such as grinding and/or sieving to provide the desired particle size (e.g., about 50 microns to about 500 microns). The encapsulated sweetener composition then may be coated with an additional hydrophobic coating layer if desired using conventional fluidized bed techniques. The particles may be added at any point in the gum-making process described above.  
      Other non-limiting examples of methods of encapsulating the natural and/or synthetic high-potency sweetener composition include agglomeration using maltodextrin as a bulking agent with starch and a gum, melt spinning after dissolving the natural and/or synthetic high-potency sweetener in a melted wall material, double coating co-dried polyvinyl acetate and the natural and/or synthetic high-potency sweetener, granulating the natural and/or synthetic high-potency sweetener with polyvinyl acetate, alcohol, and modified cellulose, and other processes such as entrapment and coacervation.  
      Prior to encapsulation, the natural and/or synthetic high-potency sweetener may be spray-dried in combination with any suitable vehicle known to those of ordinary skill in the art. Non-limiting examples of such vehicles include gum arabic, starch, and maltodextrin. Generally, the vehicles are used at a concentration of approximately 20% (w/v) in water, with the natural and/or synthetic high-potency sweetener comprising from about 0.1 to about 30% by weight of the spray-dried composition.  
      In another particular embodiment, the sweetness of the chewing gum composition is extended during the chewing period by adding the natural and/or synthetic high-potency sweetener in a form that provides longer sweetness extension, such as that provided by encapsulation, co-drying, and agglomeration. The sweetness intensity also can be controlled over the duration of the chewing period using methods such as encapsulation or admixture of the natural and/or synthetic high-potency sweetener with substances well known to those of ordinary skill in the art.  
      In a particular embodiment, the chewing gum compositions are comprised of agglomerated components. Not wishing to be bound by any theory, it is believed that physical modifications of the natural and/or synthetic high-potency sweetener by agglomeration may slow its release during the chewing period by reducing the solubility or dissolution rate of the natural and/or synthetic high-potency sweetener. Briefly described, agglomerations are prepared by mixing an absorbent with an agglomerating agent in powder form, spraying a solution of the natural and/or synthetic high-potency sweetener onto the powder as mixing continues, removing the powder from the mixer, drying to remove the solvent, and grinding to a desired particle size. Desirably, the absorber comprises a silica and the agglomerating agent comprises a cellulose derivative. Other non-limiting examples of absorbers include silicates, maltodextrin, clays, spongelike beads or microbeads, amorphous sugars, amorphous carbonates and hydroxides, vegetable gums, and other spray dried materials. The agglomerated particles may be added at any point in the gum-making process described above.  
      In another particular embodiment, the physical form in which the natural and/or synthetic high-potency sweetener composition exists when added to the chewing gum composition may affect its sweetness extension and intensity during the chewing period, Non-limiting examples of different physical forms for natural and/or synthetic high-potency sweeteners include powdered, granular, extruded, compacted, or particular forms. In a particular embodiment, the natural and/or synthetic high-potency sweetener may be anhydrous, amorphous, partially hydrated, or solvated. The sweetness extension and intensity of these forms may be altered further by encapsulation or agglomeration, as described hereinabove.  
      In still another particular embodiment, the sweetness and flavor extension properties of the natural and/or synthetic high-potency sweetener may be altered by dissolving the sweetener composition in a food acceptable solvent prior to being added to the chewing gum formulation. Non-limiting examples of suitable solvents include ethanol, propylene glycol, glycerin, glycerol triacetate, vegetable oil, etyl acetate, and combinations thereof. In addition, flavoring agents may be used as solvents either individually or as a blend. The optimal solubility level of the natural and/or synthetic high-potency sweetener in a desired solvent may be determined by those of ordinary skill in the art.  
      In one particular embodiment, the chewing gum composition comprises a liquid fill composition and a gum region comprising a gum base surrounding the liquid fill.

     Example E1  
      A mixture of crude rebaudioside A (41% purity, 50 g), ethanol (95%, 160 mL), methanol (99.8%, 60 mL) and water (25 mL) were combined by stirring at 22° C. A white product crystallized out in 5-20 hours. The mixture was stirred for additional 48 hours. The white crystalline product was filtered and washed twice with ethanol (95%, 25 mL). The wet cake of white crystalline product then was slurried in methanol (99.8%, 200 mL) for 16 hours, filtered, washed twice with methanol (99.8%, 25 mL), and dried in a vacuum oven at 60° C. for 16-24 hours under reduced pressure (20 mm) to give 12.7 g of purified product (&gt;97% by HPLC).  
     Example E2  
      A mixture of crude rebaudioside A (48% purity, 50 g), ethanol (95%, 160 mL), methanol (99.8%, 60 mL) and water (25 mL) was combined by stirring at 22° C. The white product crystallized out in 3-6 hours. The mixture was stirred for additional 48 hours. The white crystalline product was filtered and washed twice with ethanol (95%, 25 mL). The wet cake of white crystalline product then was slurried in methanol (99.8%, 300 mL) for 16 hours, filtered, washed twice with methanol (99.8%, 25 mL) and dried in a vacuum oven at 60° C. for 16-24 hours under reduced pressure (20 mm) to give 18.6 g of purified product (&gt;97% by HPLC).  
     Example E3  
      A mixture of crude rebaudioside A (55% purity, 50 g), ethanol (95%, 160 mL), methanol (99.8%, 60 mL) and water (25 mL) was combined by stirring at 22° C. The white product crystallized out in 15-30 minutes. The mixture was stirred for an additional 48 hours. The white crystalline product was filtered and washed twice with ethanol (95%, 25 mL), The wet cake of white crystalline product was slurried in methanol (99.8%, 350 mL) for 16 hours, filtered, washed twice with methanol (99.8%, 25 mL) and dried in a vacuum oven at 60° C. for 16-24 hours under reduced pressure (20 mm) to give 22.2 g of purified product (&gt;97% by HPLC).  
     Example F  
      A solution of rebaudioside A (&gt;97% pure by HPLC ) was prepared in double distilled water (12.5 gm in 50 mL, 25% concentration) by stirring the mixture at 40° C. for 5 minutes. An amorphous form of_rebaudioside A was formed by immediately using the clear solution for spray drying with the Lab-Plant spray drier SD-04 instrument (Lab-Plant Ltd., West Yorkshire, U.K.). The solution was fed through the feed pump into the nozzle atomizer which atomized it into a spray of droplets with the help of a constant flow of nitrogen/air. Moisture was evaporated from the droplets under controlled temperature conditions (about 90 to about 97° C.) and airflow conditions in the drying chamber and resulted in the formation of dry particles. This dry powder (11-12 g, H 2 O 6.74%) was discharged continuously from the drying chamber and was collected in a bottle. The solubility in water at room temperature was determined to be &gt;35.0%.
