Fat blooming inhibitor

## Abstract

A process for producing an instant no-bake filling mix which upon reconstitution or hydration has an improved glossy, smooth, creamy and firm texture with a sliceable pie cut characteristic on setting. A pre-filling mix is provided by mixing all dry ingredients and then incorporating fat or oil.

## Background
The present invention relates to a process for producing an improved filling mix and on hydration without cooking or baking produces a smooth, creamy and firm texture with a sliceable pie cut characteristic on setting.

The trend requires food preparation to be of the type of instanteous use. This means that in instant pudding or instant filling preparations, these foods are prepared from a dry mix without cooking. The difficulty associated with these conveniences is that starting materials used to prepare these high quality instant foods must be carefully controlled and the tolerance of these controls are exceptionally tight wherein many of these formulations are not considered satisfactory and require recycling, reworking, etc. of the finished dry mixes increasing the costs of production.

U.S. Pat. No. 4,361,592 issued to Carpenter et al. describes a pudding mix composition which, when combined with milk produces a desirable, creamy, glossy pudding. This is accomplished using fine particles of pregelatinized starch having less than a maximum of 1% by weight of the starch having a particle diameter greater than 63 microns (i.e., retained on a 230 mesh U.S. Standard Screen). A regular starch would generally have a particle size wherein less than 50% by weight of the starch particles pass through a 400 mesh U.S. Standard Screen with a substantial amount of the starch being retained on a 230 mesh U.S. Standard Screen (e.g., greater than 10%, usually greater than 25-50% by weight of the starch). U.S. Pat. No. 4,438,148 issued to O'Rourke et al. describes the use of controlled sized finely divided starch and controlled sized finely divided sugar particles to achieve a desirable, creamy, glossy pudding while U.S. Pat. No. 4,469,712 issued to Katcher et al. claims an improved dry instant pudding mix made from controlled sized starch and sugar.

U.S. Pat. No. 2,554,143 issued to Hinz et al. teaches that finely divided starch particles can be used in an instant pudding mix, only if their rate of hydration is retarded. Hinz et al. achieve the hydration rate retardation by coating the starch with a hydrophobic rate retardation by coating the starch with a hydrophobic material such as a lipid or talc. The problem Hinz et al. recognized is that when fine starch particles hydrate, there is a tendency for these particles to lump to the point when it is quite difficult to prepare a smooth pudding product.

U.S. Pat. No. 4,518,622 issued to Wison et al. describes a product and process for the making of a dry mix capable of being hydrated in an aqueous medium to form, without need for cooking, a firm gelled mass suitable for use as a pastry or pie filling having textural and organoleptic properties similar to those possessed by a cooked, starch-based filling. This product is produced by mixing sugar, starch, food-grade acidulant and appropriate amounts of flavorants and/or colorants. The starch component provides specific properties of viscosity and texture to the hydrated product. This procedure, however, provides a very grainy, lumpy appearance resembling an apple sauce product. This appearance is not desired in the production of pie fillings or puddings.

In a copending application U.S. Ser. No. 802,544 filed Nov. 27, 1985 now U.S. Pat. No. 4,636,397, issued Jan. 13, 1987, being commonly assigned to this application, there is a method described which provides an instant mix, and on reconstitution or hydration a no bake pie-filling mix is produced which has an improved glossy, smooth, creamy and firm texture with a sliceable pie cut characteristic on setting. This is accomplished by uniformity oil coating the natural carbohydrate sweetener solid particles with a liquid hydrogenated or partially hydrogenated edible oil, then dry mixing the oil coated sweetener with a rapid hydratable cold water swelling starch, maltodextrin, flavorants and the like to provide a flowable powder. This is accomplished in two steps to provide a highly desirable product in the presence of maltodextrin.

The present invention provides another process for making an improved instant filling mix which on reconstitution produces a highly desirable glossy, smooth, creamy and firm texture with a sliceable pie cut characteristic on setting made from standard and finely divided particles, normally sized ingredients of filling mix such as starch, sugar or other sweeteners as well as other materials.

A process has been discovered for making an improved instant filling mix which on hydration produces a smooth, creamy and firm texture with a sharp pie cut characteristic on setting. The process includes the following steps:

(A) Dry mixing (1) a natural carbohydrate sweetener solid particles; (2) a rapid hydratable cold water swelling starch; (3) maltodextrin having a dextrose equivalent between about 5 and about 20; (4) flavor(s) and (5) edible food acid(s) for a period of time sufficient to obtain a substantially uniform mix.

(B) The product of (A) is mixed with about 4 to about 6 weight % of the total mixture of a liquid hydrogenated or partially hydrogenated edible oil until a uniform mixture of a flowable powder is obtained.

It has been discovered in this invention that if all the ingredients of sweetener, starch, malto-dextrin and/or flavor and edible foods are uniformly mixed and an edible oil in amounts ranging from about 4 to about 6 weight percent of the total composition is mixed with the premixed ingredients, the resulting product, on hydration, produces a smooth, creamy and firm texture with a sliceable pie cut characteristic on setting. If the maltodextrin or starch present in the mix, is added with oil prior to use with the remaining ingredients, a smooth and creamy filling will not be obtained in some instances because uniform distribution of the ingredients will not be achieved and, if a smooth and creamy filling is achieved, the set pie filling on prolonged setting will be syneresed to the point where the set will break down. To assure the smooth and creamy texture of the filling made by this invention, malto-dextrin is used to aid the uniform distribution of the ingredients on hydration. If maltodextrin is not used, the resulting product is lumpy, grainy and not acceptable as a high quality filling mix.

The weight percentage of ingredients used in the process of this invention based on the total composition are as follows: Ingredients       Weight Percentage ______________________________________ natural carbohydrate sweeteners about 55 to about 80% preferably about 60 to about 68% rapid hydratable cold water about 16 to about 20% swelling granular starch preferably about 17 to about 19% malto-dextrin having a dextrose about 5 to about 15% equivalent between about 5 to preferably about 8 to about 20 preferably about 9 to about 10% about 12 edible oil        about 4 to about 6% preferably 4.5 to about 5.5% flavor            below about 1% preferably about 0.2 to about 0.5% as needed edible food acid  0 to about 5% preferably about 1.0 to about 1.5% color             as needed ______________________________________

Additional ingredients, if desired, can be used in the above combination of materials to enhance taste, flavor, sweetness and whatever is needed to provide a satisfactory food product.

In this invention, the natural carbohydrate sweetener which can be used is sugar from any source available in dry granular form such as sucrose or dextrose as well as other solid sweeteners such as fructose, corn syrup solids, or mixtures thereof among other natural sweeteners. These sweeteners must be free flowing particles of suitable size to make instant mixes.

Various maltodextrins (hydrolyzed cereal solids) which are starch hydrolysates produced by converting pure refined corn starch into nutritive saccharides through the use of acids or specific enzymes, are used in this invention. The carbohydrate composition of maltodextrin is arranged to yield a dextrose equivalent from about 5 to about 20, preferably 7 to about 12. These are typically bland in flavor and without appreciable sweeteners. This maltodextrin is a free-flowing powder and its presence is for aiding the uniform distribution of all ingredients on hydration.

The rapid hydratable cold water swelling starch of this invention are being used as a thickening agent. These starches are obtained from a variety of starch sources such as tapioca, corn, high amylose, sweet potato, potato, waxy maize, canna, arrowroot, sorghum, waxy sorghum, waxy rice, sago rice and the like. The essential feature of the starch is that it is a rapid hydratable cold water swelling starch, preferably granular, which will set up on hydration with all the remaining ingredients present at room temperature in a reasonable time preferably in less than 2 hours and preferbly less than 1 hour in a smooth, creamy and firm texture with a sliceable pie cut characteristic. The type of starches that can be used can include the types of starches described in U.S. Pat. No. 3,949,104 issued to Hsiung Cheng, among other and commercially available, cold-water swelling starches identified as NU-COL 231, NU-COL 326, NU-COL 4227, MIRA-GEL 463 (manufactured and sold by the A. E. Staley Manufacturing Company, Decatur, Ill.). The preferred starch is the MIRA-GEL 463 which is a cold water swelling starch which hydrates in water at ambient temperatures, first forming to a thick smooth consistency and then setting to a resilient colloidal gel structure. The particle size of the starch is that which is normally used in the instant pudding or pie fillings, i.e., particle size wherein 95% passes through 100 Mesh U.S. Standard Screen and at least 65% passes through a 200 mesh U.S. Standard Screen. Finer particles can be used if desired. It is essential that the size particles of the starch are such that in the combination of the other ingredients a free-flowing powder is available. The term "cold water swelling" as used herein relates to the use of water for hydration below the boiling point of water, preferably below  150.degree. F. and more preferably below 120.degree. F. and ideally at room temperature or ambient temperatures.

The edible oil which is used herein is a liquid at use and preferably liquid at room temperature and can be any food acceptable hydrogenated or partially hydrogenated edible oil. The preferred oils are the hydrogenated vegetable oil including, among others: coconut oil, palm kernel oil, cottonseed oil, peanut oil, soybean oil, canola oil, corn oil and mixtures thereof. The oils used herein cannot have a taste or flavor which would interfer with the desirable taste and flavor of the filling mix.

The flavors used in this invention can be any acceptable flavors. These include among others, lemon, cherry, almond, pecan, strawberry, orange, lime, blueberry, raspberry and the like.

The edible food acids which can be used include, among others, citric acid, malic acid, adipic acid, fumaric acid, tartaric acid, or mixtures thereof.

After all the ingredients have been dry mixed, prior to the hydration step, the resulting product must be a flowable powder. On hydration, the product of this invention produces, without cooking or baking, a smooth, creamy and firm texture with a sharp pie cut characteristic on setting.

The sugar content of Example II was increased over Example I to provide the same solids content since Example II was prepared without maltodextrin. The mixing procedure of Example I was followed wherein the hydrogenated oil was added to the homogenous dry mix without maltodextrin and mixed for 10 minutes until a homogeneous flowable powder product was obtained. In a mixer containing 2 cups of hot water at 120.degree. F.; where the beaters are immersed in the water and rotating, 245.5 grams of the above flowable powder product was slowly sprinkled on top of the water until all the product was added. The mixing continued for two minutes. The resulting product was poured into a container and allowed to set up for 45 minutes. The product was a very grainy, lumpy pie filling resembling an apple sauce product. This is not acceptable in regard to the required creamy and smooth property of Example I. The texture, however, was firm and had a sliceable cut characteristic.

The process of Example I was repeated except the hydrogenated vegetable oil was mixed with the malto-dextrin. The starch was added to the oiled malto-dextrin and mixed thoroughly. The remaining dry ingredients were added to the oiled maltodextrin and starch and mixed for 15 minutes. The resulting product was added to 2 cups of hot water (120.degree. F.) and mixed until smooth. Two egg yolks and one tablespoon of melted butter, used to add body, were added to the mixture and mixed again. The mixture was poured into a pie plate and set in one hour. The filling was smooth and creamy, however, on prolonged sitting, the product syneresed to the point where the set broke down.

The procedure of Example III was repeated except the starch was mixed with hydrogenated vegetable oil and the remaining ingredients were dry mixed with the oiled starch. The result of this example was similar to that of Example III that being a smooth product but the break down in set occurred on prolonged sitting.

The above disclosure has provided a description of the invention for the purpose of enabling the person skilled in the art how to make and use the same and has not been made for the purpose of detailing all things known or obvious to the skilled worker. Upon reading this disclosure, many modifications and variations be included within the scope of the present invention which is defined by the following claims.
