Title: Method and system for flash freezing energy drinks and making beverages therefrom

Description:
RELATED APPLICATIONS 
     The present application claims priority to provisional Patent Application Ser. No. 61/276,987 filed Sep. 18, 2009, the disclosure of which is incorporated by reference herein, in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to beverages and more particularly to an apparatus and method for creating a flash frozen energy beverage. 
     BACKGROUND OF THE INVENTION 
     Various energy drinks are available that have different ingredients that are intended to raise a person&#39;s heart rate, improve stamina, provide extra energy, and raise alertness. Some drinks are served chilled, some hot, and some with extra ingredients and toppings as well. Regardless of the way most energy drinks are served, they typically are served in a ready-to-go can or bottle or concocted by a skilled person at a bar, whether at a fitness center, restaurant, or nightclub. 
     Keeping the drinks fresh is important to maintaining the palatability of the drinks. There are many techniques that have previously been used to try to maintain freshness, but eventually an expiration date is reached where the drink loses it freshness. 
     There remains the need, therefore, for a product and method of its manufacture and use which allows quality energy drinks to be easily and affordably produced by a typical consumer and that have an extended shelf life. 
     SUMMARY OF THE INVENTION 
     Embodiments of the present invention relate to a method of flash freezing an energy drink liquid into small beads and then packaging the beads for consumers. The beads are stored in a conventional freezer, or colder, until desired and then reconstituted into an energy beverage as needed or consumed in their beaded form. In particular, a cold or warm energy beverage may be easily and affordably created using the frozen beads. 
     It is understood that other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein it is shown and described only various embodiments of the invention by way of illustration. As will be realized, the invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the invention. 
     Generally energy drinks include methylxanthines (including caffeine), vitamin B and herbs. Other common ingredients are guarana, acai, and taurine, plus various forms of ginseng, maltodextrin, carbonated water, inositol, carnitine, creatine, glucuronolactone and ginkgo biloba. Some contain high levels of sugar, and many brands also offer artificially-sweetened ‘diet’ versions. The central ingredient in most energy drinks is caffeine, the same stimulant found in coffee or tea, often in the form of guarana or yerba mate. The average 237 milliliter (8 fluid ounce) energy drink has about 80 mg of caffeine, with 480 mL (16 fl. oz.) drinks containing around 150 mg. Energy drinks are sometimes mixed with alcohol. 
     As a result of the methods described herein, there are provided formulations of frozen energy beverages in the form of small particulate shapes that remain free-flowing during storage and which can be used alone or in combination to be reconstituted into various energy beverages, or consumed in their beaded form. The particulate shapes, generally referred to as “beads”, may have a generally spherical, spheroid shape but may also have an oblong, elliptical, oblate, tubular, or other slightly irregular shape. In addition to having an irregular overall shape, the surface of the particulate shape may also be either smooth or irregular (e.g. bumpy, pocked, etc.). On average, the particulate shapes will preferably have a diameter of about 5 mm or less but can also be larger such as between about 6 and about 10 mm. Particulate shapes having diameters outside these ranges are also contemplated. For non-spherical shapes which do not have a conventional diameter, the diameter is considered to be the diameter of the smallest sphere into which the particulate shape would fit. 
     It is desired that the particulate or beaded product is in a free-flowing format so that it is readily pourable or spoonable. Free-flowing, as used herein, is a broad term which includes the ability of the product to flow as individual particulate shapes, with little or no clumping or sticking to each other, during such pouring or spooning. There may be slight sticking after a period of storage, but a light tap on the container will unstick the particulate shapes and allow them to be free flowing. The generally spherical shape helps contribute to the free-flowing, pourable product. 
       FIG. 1  shows a cryogenic processor constructed in accordance with an embodiment of the present invention to produce free-flowing beads  56 . 
     A cryogenic processor  10  includes a freezing chamber  12  that is most preferably in the form of a conical tank that holds a liquid refrigerant therein. A freezing chamber  12  incorporates an inner shell  14  and an outer shell  16 . Insulation  18  is disposed between the inner shell  14  and outer shell  16  in order to increase the thermal efficiency of the chamber  12 . Vents  20  are also provided to ventilate the insulated area formed between the shells  14  and  16 . The freezing chamber  12  is a free-standing unit supported by legs  22 . 
     A refrigerant  24 , preferably liquid nitrogen, enters the freezing chamber  12  by means of refrigerant inlet  26 . The refrigerant  24  is introduced into a chamber  12  through the inlet  26  in order to maintain a predetermined level of liquid refrigerant in the freezing chamber because some refrigerant  24  can be lost by evaporation or by other means incidental to production. Gaseous refrigerant that has evaporated from the surface of the liquid refrigerant  24  in freezing chamber  12  primarily vents to the atmosphere through exit port  29  which cooperates with the vacuum assembly  30 , which can be in the form of a venturi nozzle. Extraction of the frozen beads occurs through product outlet  32  adapted at the base of the freezing chamber  12 . 
     An ambient air inlet port  28  with adjustment doors  38  and exit port  29  with adjustment doors  39  are provided to adjust the level of gaseous refrigerant which evaporates from the surface of the liquid refrigerant  24  so that excessive pressure is not built up within the processor  10  and freezing of the liquid composition in the feed assembly  40  does not occur. 
     A feed tray  48  receives liquid composition from a delivery source  50 . Typically, a pump (not shown) drives the liquid composition through a delivery tube  52  into the feed tray  48 . A premixing device  54  allows several compositions, not all of which must be liquid, such as powdered flavorings or other additives of a size small enough not to cause clogging in the feed assembly  40 , to be mixed in predetermined concentrations for delivery to the feed tray  48 . 
     In order to create uniformly sized particles or beads  56  of frozen product, uniformly sized droplets of liquid composition are desirable that are to be fed through gas diffusion chamber  46  to freezing chamber  12 . The feed tray  48  is designed with feed assembly  40  that forms droplets of the desired character. The frozen product takes the form of beads that are formed when the droplets of liquid composition contact the refrigerant vapor in the gas diffusion chamber  46 , and subsequently the liquid refrigerant  24  in the freezing chamber  12 . After the beads  56  are formed, they fall or are mechanically directed to the bottom of chamber  12 . A transport system connects to the bottom of chamber  12  at outlet  32  to carry the beads  56  to a packaging and distribution network for later delivery and consumption. 
     The vacuum assembly  30  cooperates with air inlet  28  and adjustment doors  38  so that ambient air flows through the inlet and around feed assembly  40  to ensure that no liquid composition freezes therein. This is accomplished by mounting the vacuum assembly  30  and air inlet  28  on opposing sides of the gas diffusion chamber  46  such that the incoming ambient air drawn by the vacuum assembly  30  is aligned with the feed assembly. In this configuration, ambient air flows around the feed assembly warming it to a sufficient temperature to inhibit the formation of frozen liquid composition in the feed assembly flow channels. An air source  60 , typically in the form of an air compressor, is attached to vacuum assembly  30  to provide appropriate suction to create the ambient air flow desired. 
     In accordance with preferred embodiments, there are provided formulations of frozen energy drink confections in the form of small particulate shapes. The particulate shapes may have a generally spherical, spheroid shape as shown in  FIG. 2  (e.g.,  1001 ,  1003 ,  1005 ), but may also have an oblong, elliptical, oblate, tubular, or other slightly irregular shape as also shown in  FIG. 2  (e.g.,  1007 ,  1009 ). In addition to having an irregular overall shape, the surface of the particulate shape may also be either smooth or irregular (e.g. bumpy, pocked, etc.). On average, the particulate shapes will preferably have a diameter of about 0.05 inch to about 0.5 inch or less, including 0.4 inch, 0.3 inch, 0.25 inch, 0.2 inch, 0.15 inch, and about 0.1 inch, and ranges including and bordered by these dimensions. Particulate shapes having diameters outside these ranges are also contemplated. For non-spherical shapes which do not have a conventional diameter, the diameter is to be the diameter of the smallest sphere into which the particulate shape would fit. 
     As mentioned earlier, it is desired that the beaded product is in a free-flowing format so that it is readily pourable or spoonable. Free-flowing, as used herein, is a broad term which includes the ability of the product to flow as individual particulate shapes, with little or no clumping or sticking to each other, during such pouring or spooning. There may be slight sticking after a period of storage, but a light tap on the container will unstick the particulate shapes and allow them to be free flowing. The generally spherical shape helps contribute to the free-flowing, pourable product. 
     In preferred embodiments, particulate shapes that can be stored at higher temperatures, such as in a home freezer or in a grocery dairy freezer are provided, such particulate shapes being able to maintain a free-flowing form while being stored at a temperature between about −10° F. and 0° F. with an occasional rise to perhaps as much as +5° F. One way to accomplish this is to increase the freezing point (reduce the freeze-point depression) of the liquid formulation that forms the particulate shapes, although other ways may also be used. Storage at even colder temperatures is contemplated as well. 
       FIG. 3  depicts a flowchart of an exemplary method of making energy beverage particulate beads in accordance with the principles of the present invention. 
     The first step  302  shown in  FIG. 3  is that of preparing the energy beverage liquid. While the base ingredient of this liquid is the energy beverage formulation, there are a number of additional ingredients and flavors that may be added as well during the preparation process, in accordance with other embodiments. Dairy products, flavored syrups, flavored oils, sugars, sweeteners, herbs, spices and the like may be added, for example in a raw form or pre-processed form. In preparing the energy beverage liquid, the liquid may be processed to have a particular strength, caffeine content, or other desired characteristic. Also, flavors from various liqueurs and syrups, as well as the ingredients listed above, may be part of the formulation as well, either before or after the energy beverage liquid is prepared. The number of various formulations that may be turned into energy beverage liquids in accordance with the principles of the present invention are limited only by the creativity of the food scientist and the preferences of consumers. 
     Once the liquid is prepared, another opportunity exists, at step  304 , to add additional flavors, ingredients or additives in order to formulate a variety of different liquids. In step  306 , the energy beverage liquid is cooled if desired. The cooling can be accomplished by a variety of different methods that are well known. Preferably the liquid is cooled to about 40° F. in a matter of minutes or less. While as low a temperature as possible is desirable to improve the efficiency of later cryogenic processing, the temperature to which the liquid is cooled depends on the desired viscosity of the liquid as it is transported through to later stages of processing. Thus, additives may be included, such as stabilizers, which allow cooling to lower temperatures while ensuring the liquid easily flows and improve the liquids freezing characteristics. The energy beverage liquid is transported such as by being pumped, in step  308 , to a frozen bead-making apparatus such as, for example, the device shown and described earlier with respect to  FIG. 1 . As mentioned, the consistency of the liquid may be adjusted to accommodate the pump  50  and the temperature of the liquid may be adjusted as well by well known cooling techniques that can be applied during transport to the freezing apparatus. The temperature and consistency may also be adjusted to help the development of uniformly-sized beads within the freezing apparatus. Depending on the viscosity of the original fluid, different temperatures and consistencies may be used for different liquids that are dispensed into the freezing apparatus. 
     The next step,  310 , is to freeze the energy beverage liquid into beads as described with respect to  FIG. 1 . These beads can then be transported to a packaging machine to be packaged (step  312 ). The transporting of the beads can be accomplished in a variety of different ways such as by a feed screw, a moving conveyor belt, or gravity feed. The transporting means can also be cooled such that the beads remain cool while being transported to the packager. 
     One of ordinary skill will recognize that different flavored beads may be frozen in separate freezing apparatuses at the same time or in the same freezing apparatus in a sequential manner. These different flavor beads can then be combined in different ratios at the packaging machine. In this way, different combinations of flavored energy beverages may be created using the same set of beads in various permutations and combinations. Of course, a product consisting of one type of flavored bead is contemplated. 
     Once the beads are packaged and delivered to a consumer such as an individual, a retail location, a bar, a fitness center, a coffee shop, a store, or a restaurant, the beads are stored in a conventional freezer until they are used to make a beverage, or consumed in their beaded form. Although the beads are frozen at cryogenic temperatures, there is no requirement that they remain cooled to temperatures as low as −40° F. but, instead, may be maintained at the standard operating temperatures of commercial and consumer freezers. However, storing them at even lower temperatures may allow using less of the beads to cool a beverage to a desired temperature. 
     The ultimate use for the frozen beads is to be consumed in beaded form or to use them to produce a beverage for consumption. This can be accomplished in a variety of different ways without departing from the scope of the present invention. For example, the frozen beads may be brewed or steamed to reconstitute them. The frozen beads may also be ground similar to regular coffee beans and used to make beverages. 
     Accordingly, the packaging of the frozen beads can be accomplished in a variety of different ways depending on the desired product. For example, the beads may be packed in a cup sized container that is for a single serving, the cup can then be microwaved to make a hot beverage that can be used as the base in a variety of drinks. Alternatively, the beads can be packaged in bulk packages from which a user can extract the desired amount of product to be reconstituted or consumed. 
     In general, a flowchart is shown in  FIG. 4  of a method for making an energy drink from the frozen beads described earlier. In step  402 , the desired amount of beads are selected. These beads are flash-frozen energy beverage beads as described earlier. Depending on the desired beverage and the type of beads, the amount of beads will vary. For example, for a 12 to 16 oz. drink, anywhere from about 1 oz. to 3 oz. of beads can be used. However, this ratio of ingredients can vary based on a desired beverage taste without departing from the scope of the present invention, as well as the relative concentration of the energy drink within the beads. For example, removing various amounts of water from the energy beverage before freezing can be used to control flavor, texture, and concentration. 
     Next, in step  404 , the beads are warmed or heated by any of a variety of methods. Warming them in a pan, microwaving them, heating them with hot steam, etc. are all methods that can be used to create a reconstituted beverage base. Additionally, one of ordinary skill will recognize that any other well known method of warming the beads can be utilized without departing from the scope of the present invention. The resulting beverage base can be a stand-alone beverage or potentially combined with other ingredients to form other energy beverages. 
     The ingredients that will be combined with this beverage base can vary widely. For example, milk, frothed milk, steamed milk, cream, and whipped cream are all likely candidates to add so as to make a variety of warm beverages. Furthermore, the milk can vary from 1%, 2%, skim, lowfat, whole, and untraditional milk products such as soy, rice, goat, and the like. These additional ingredients can also includes syrups and flavors such as those traditionally paired with energy drinks such as chocolate, vanilla, hazelnut, Irish creme, caramel, peppermint, butter rum, mint, coffee liqueur, and others. Various forms of water, fruit drinks, and other liquids may also be added. Thus, in step  406 , the additional ingredients are prepared in a manner appropriate for addition to the beverage base and then everything is combined in step  408  to create a warm beverage. 
     In addition to the beads discussed above, embodiments of the present invention also contemplate energy beverage beads that more closely resemble flash frozen ice cream products. 
     An exemplary method of manufacturing the energy drink frozen food product, includes preparing a formulation, wherein the formulation is preferably made by combining liquid ingredients, combining dry powders, and mixing the combined dry powders with the combined liquids to make the formulation, and where the method continues by agitating the formulation, pasteurizing the formulation if desired, homogenizing the formulation if desired, aging the formulation, and dripping the formulation into a cryogenic processor to form a particulate frozen food product. In a preferred embodiment, the homogenizing step acts to synchronize the pasteurizing step. In certain embodiments, based on the ingredients of the formulation, the pasteurizing step may be omitted. Also, one or more of the other steps in the above list may be optional depending on the formulation and desired end product. 
     One ultimate use for the flavored frozen beads is to use them to produce a beverage for consumption. This can be accomplished in a variety of different ways without departing from the scope of the present invention. For example, for warm beverages as discussed above, the frozen beads may be brewed or steamed to reconstitute them. The frozen beads may also be ground similar to regular coffee beans and used to flavored beverages. However, another benefit of the frozen beads is that they may be used or mixed to create cold energy drinks while reducing or eliminating the need for ice cubes. Thus, the resulting beverage is not as watered-down as if ice cubes are used to make the cold drink. Also, because of the freezing method, ice crystal formation will be different than if ice cubes are used which improves the mouth-feel of the resulting beverage. Milk, water and other liquids may be used when reconstituting the frozen beads into the desired beverage. 
     Accordingly, the packaging of the frozen beads can be accomplished in a variety of different ways depending on the desired product. For example, the beads may be packed in a cup sized container that is for a single serving. For example, 8 oz. of beads (whatever variety or combination) may be packaged in a cup with room for 8 oz. of milk (or other liquid) to be added. Additional room can be provided in order to accommodate other additional flavors and confections. Alternatively, the beads can be packaged in bulk packages from which a user can extract the desired amount of product to be reconstituted. 
     Utilizing the either type of beads described earlier, various ingredients can be added to create cold beverages. In general, a flowchart is shown in  FIG. 5  of a method for making an energy drink from the frozen beads described earlier. In step  502 , the desired amount of beads is acquired. Depending on the desired beverage and the type of beads, the amount of beads selected in step  502  will vary. 
     The ingredients that will be combined with this beverage base can vary widely. For example, milk, frothed milk, steamed milk, cream, and whipped cream are all likely candidates to add so as to make a variety of cold beverages. Furthermore, the milk can vary from 1%, 2%, skim, lowfat, whole, and untraditional milk products such as soy, rice, goat, and the like. These additional ingredients can also includes syrups and flavors such as those traditionally paired with energy beverages such as chocolate, vanilla, hazelnut, Irish creme, caramel, peppermint, butter rum, mint, coffee liqueur, and others. In the cold beverages fruity flavors, soda water, and ice can be added as well. Thus, in step  504 , the additional ingredients are prepared in a manner appropriate for addition to the beverage base and then everything is combined in step  506  to create a cold beverage. In step  508 , the strength of the flavor in the cold beverage can be increased by adding other beads as desired by the user. 
     An exemplary method of manufacturing the energy-drink flavored frozen food product, includes preparing a formulation, wherein the formulation is preferably made by combining liquid ingredients, combining dry powders, and mixing the combined dry powders with the combined liquids to make the formulation, and where the method continues by agitating the formulation, optionally pasteurizing the formulation, homogenizing the formulation, aging the formulation, and dripping the formulation into a cryogenic processor to form a particulate frozen food product. In a preferred embodiment, the homogenizing step acts to synchronize the pasteurizing step. In certain embodiments, based on the ingredients of the formulation, the pasteurizing step may be omitted. Also, one or more of the other steps in the above list may be optional depending on the formulation and desired end product. 
     One example of a formulation for a energy drink flavored frozen food product, includes water and total solids, wherein the food product may include, in addition to energy drink flavor, 6-14% by weight milk fat, 4-24% by weight non-fat milk solids, and 2.6-8% by weight sugar. In preferred products the product is in the form of particulate shapes which remain free-flowing when stored in a freezer at 0° F. In certain embodiments, the food product further includes one or more of the following: 0.1-0.4% by weight sweetener; 1-20% by weight bulking agent; 0.1-1% by weight of cryoprotectant; one or more natural and/or artificial flavors; and 1-4% combined stabilizer/emulsifier. In certain embodiments, the product may have at least about 29% by weight total solids and less than about 71% by weight liquid (mostly energy drink liquid) allowing the product to remain free flowing when stored in a freezer at 0° F. Preferred bulking agents include, but are not limited to, maltodextrins. 
     As stated, it is desired to store the particulate shapes within a conventional freezer and yet still maintain their free-flowing properties. To achieve this, various sample liquid formulations used in making the particulate shapes will now be described some which are dairy based and some which are not. It should be noted that the formulations described below are only examples, and numerous other formulations containing various amounts of ingredients as described herein may be made. Some of the components of three different example formulation types are as follows (all percentages are by weight of the total formulation):

     The freezing point of the various formulations disclosed herein which form the particulate shapes can be increased by making adjustments to one or more of the above components, and some adjustments work better in combination with each other. As shown above, some of the formulations above comprise various total solids combined with water. Within the particulate shapes, water is present both as a liquid and as a solid. This is because not all water freezes, due to the presence of dissolved solutes and the cryogenic freezing itself. The solid/liquid ratio within the particulate shapes affects their firmness. This in turn affects pourability and the ability of the particulate shapes to remain free-flowing. Other factors may affect the pourability, including, but not limited to, size of the ice crystals, freezing point, melting point, glass transition temperature, presence or absence of devitrification, storage temperature and conditions. 
     In the United States, the total solids content must be 35.55% to legally describe a product as ice cream. Accordingly, formulations according to formulation I are considered ice creams in the U.S. This is because most ice creams finished ice cream product must weight at least 4.5 lb/gal and must contain at least 1.6 lb of food solids or total solids per gallon, which essentially equates to a minimum total food solids of 35.5%. In the USA, any finished product below these limits cannot be labeled ice cream. However, other countries have different requirements. For example, in several countries other than the U.S. the total solids content of a formulation can be as low as 29.7%, and possibly lower, yet still be labeled ice cream. Accordingly, formulations according to Formulation II preferably have solids at a level that is considered ice cream in jurisdictions outside the U.S. Therefore, in certain preferred embodiments, the total solids in a frozen confection is at least about 25%, at least about 26%, at least about 26.5%, at least about 27%, at least about 27.5%, at least about 28%, at least about 28.5%, at least about 29%, at least about 30%, at least about 31%, at least about 32%, at least about 33%, at least about 34%, at least about 35%, at least about 36%, or at least about 37%, wherein stated percentages are by weight of the weight of the total formulation including water. 
     One component of the solids of dairy formulations such as those according to Formulae I and II is milkfat. The milkfat, also called butterfat, in the composition provides much of the creamy texture and body to the formulation, with higher levels providing greater creaminess and richness. 
     Serum solids or nonfat milk solids are those components of milk and/or cream which are water soluble, including but not limited to caseins and other milk proteins. It is to be noted that although milkfat and water are listed as separate ingredients, milkfat, water and serum solids are, in most embodiments, included in the milks and creams that form the basis of the dairy Formulations I and II, and thus do not necessarily comprise separate ingredients. 
     Nonfat milk solids enhance the texture of ice cream, aid in giving body and chew resistance, and may be less expensive than milkfat. Whey solids, including modified whey products, may also be substituted for nonfat milk solids but, under USA federal government requirements, not for more than 25% of the total nonfat milk solids in the overall formulation. Egg yolk can also be used as another source of solids. Accordingly, in one embodiment, preferably about 1% to 25%, including 5% to 20% and 10% to 15% of the nonfat milk solids in a formulation comprise whey solids and/or egg yolk solids. 
     Emulsifiers can also be included within the various formulations, especially those containing milkfat. Preferred emulsifiers can include monoglycerides, diglycerides, and polysorbates. Stabilizers may be included within the various formulations. Stabilizers assist in controlling the viscosity of the formulations, with more stabilizer generally providing increased viscosity, especially in those embodiments having lower amounts of fats and solids. The viscosity affects the drip rate of the formulation while it is formed. Within the dairy Formulations I and II, preferred stabilizers can include guar, carrageenan, LBG, and/or CMC. Within the non-dairy Formulation III, a preferred stabilizer can include cellulose gum. 
     In those dairy embodiments where both stabilizers and emulsifiers are used, the formulations disclosed herein for making the frozen confection includes a combined stabilizer/emulsifier, and the recited amounts are the combined total of the stabilizer and emulsifier present. The combined stabilizer/emulsifier need not actually be added as a single ingredient when making the formulation; the weights of these two materials are included together because in many embodiments, commercial combined stabilizer/emulsifier formulations are used, which include one or more stabilizers and one or more emulsifiers. Accordingly, the stabilizer/emulsifier may be a commercial or proprietary formulation or it may be a combination or series of one or more stabilizers and/or one or more emulsifiers added to the formulation. 
     One or more bulking agents may also be added to formulations according to certain embodiments. Bulking agents include high molecular weight polymeric compounds (such as polysaccharides), which add viscosity and bulk to foods. Preferred bulking agents include, but are not limited to polydextrose, dextrans, corn syrup solids, and maltodextrins. In certain preferred embodiments, maltodextrins are used, including, but not limited to, those having a DE of 5, 10, 15, and 20, where DE refers to “dextrose equivalent”. In a preferred embodiment, the total amount of bulking agents is 1% to 20% by weight, including 1%-15% by weight, 5%-15% by weight, including 6%, 8%, 10% and 12% by weight. Because bulking agents and stabilizers both contribute to the viscosity of a formulation, formulations containing a bulking agent may or may not include a stabilizer or stabilizer/emulsifier. 
     While the beads can be consumed as a stand-alone product, another ultimate use for the energy drink flavored frozen beads is to use them to produce a beverage for consumption. This can be accomplished in a variety of different ways without departing from the scope of the present invention. For example, for warm beverages as discussed above, the frozen beads may be brewed or steamed to reconstitute them much like tea leaves. The frozen beads may also be ground similar to regular coffee beans and used to make energy drink flavored beverages. However, another benefit of the frozen beads is that they may be used or mixed to create cold energy drink based drinks while reducing or eliminating the need for ice cubes. Thus, the resulting beverage is not as watered-down as if ice cubes are used to make the cold drink. Also, because of the freezing method, ice crystal formation will be different than if ice cubes are used which improves the mouth-feel of the resulting beverage. Milk, water and other liquids may be used when reconstituting the frozen beads into the desired beverage.
