Description:
CO-PROCESSILD EIVIULSIFILR/CARRIER SYSTEMS FOR FULL FAT FARINACEOUS BAKED GOODS 1011 This application claims priority to provisional U. S. Application Ser. No. 60/242, 439, filed October 24,2000, which is hereby incorporated by reference in it's entirety.

FIELD OF THE INVENTION 021 The present invention relates to co-processed emulsifier/carrier system for farinaceous baked goods.

BACKGROUND OF THE INVENTION [031 Emulsifiers or surfactants are used extensively in farinaceous baked goods to improve product volume, tenderize crumb, slow the rate of crumb firming, etc. Such emulsifiers or surfactants are also known in the farinaceous baked goods industry as crumb softeners, anti-staling agents, dough conditioners, and the like. Hereinafter, the term emulsifier will be used to represent both emulsifiers and surfactants.

041 The mechanism for emulsifier functionality is well-known and is related to the amphiphilic character and resulting surface activity of the emulsifier. The use of emulsifiers in specific applications is guided not only by the hydrophilic-lipophilic balance (HLB) of the emulsifier, but also by the handling characteristics conferred by its physical form (e. g., plastic, powdered, beads, flakes). Thus, as proper dispersion of the emulsifier is crucial to its ability to function in an application, the baking industry generally uses plasticized shortening-like emulsifiers, pre-hydrated paste-like emulsifiers, fine powdered emulsifiers (especially in dry mixes), or some combination of these, for ease of processing. (See, for example, Pyler, E. J. 1988. Baking Science & Technology, 3rd ed. Sosland Publishing Company, Merriam, KS.) 105] It is desirable to produce an emulsifier system that enhances batter aeration, increases cake volume, produces a finer and more even crumb structure with softer texture, and improves storage qualities.

BRIEF SUMMARY OF THE INVENTION 061 The present invention is directed to emulsifiers that are co-processed with a carrier to produce a fine powder. The fine powder is added to the dry mix portion of full-fat baked good formulations, such as full-fat yellow layer cake formulations.

[07] Compared to the addition of dry dairy protein and powdered emulsifiers separately, the co-processed emulsifier/can-ier formulation provides enhanced batter aeration, increased cake volume, a finer and more even crumb structure with softer texture, and improved storage qualities. In addition, manufacturers can reduce the number of ingredient additions in a manufacturing process, reduce the number of ingredients required to be stocked, and produce higher-value finished goods with longer shelf- life. Further, the final products are more aesthetically pleasing and have better eating and keeping qualities.

081 The present invention is directed to a full-fat baked good composition comprising a full-fat baked good dry mixture, an emulsifier, and a carrier, wherein the emulsifier and carrier are commingled to enhance the emulsifier performance in the prepared full-fat baked good. The present invention is particularly directed to a composition comprising an emulsifier selected from propylene glycol monoesters, monoglycerides, and sodium stearyl lactylate and a carrier selected from microparticulated whey protein concentrate.

091 The emulsifier and carrier may be co-processed by spray-drying, co-drying, co- solution, co-precipitation, encapsulation, co-melting, co-milling, homogenization, or any other process involving solvation, heat, pressure and/or shear to bring about intimate commingling of the components.

[10] The present invention is also directed to a method for introducing an emulsifier into a dry mixture to produce a baked good. The method improves the dispersibihty of emulsifier and improves its functionality.

DETAILED DESCRIPTION OF THE INVENTION 111 It was discovered that enhanced functionality of an emulsifier in a full-fat baked good is achieved by improving dispersion of the emulsifier in the baked good matrix. It was further discovered that improved dispersion is achieved if the emulsifier is co- processed with a suitable carrier prior to addition to the dry mixture of a full-fat baked good mix.

121 In accordance with the invention, the emulsifier/carrier is introduced into a full-fat baked good mix, such as cake mixes, in such as manner to improve the dispersibility of the emulsifier and to improve its functionality over current state-of-the-art. The emulsifierlcarrier is introduced and mixed into the dry ingredients. After the dry ingredients are mixed, the dry ingredients may be packaged for storage or the requisite wet ingredients, e. g. oil, eggs, water, to prepare the baked good may be added.

131 The emulsifier/carrier combination is known for use in low fat baked good mixtures as a fat replacement. In the instant invention, the emulsifier/carrier combination is not used as a fat replacement but instead is used in full-fat recipes to improve dispersibility of the emulsifier.

141 Full-fat recipes provide a product having 6 wt% or more fat. Low fat cake recipes generally have about 3g of fat per 50g of product or up to about 3 wt% fat. Full-fat baked good mixtures in accordance with the invention include cakes mixes, pie crusts, muffins, brownies, pastries, sweet doughs, and breads, which are sold in dry mix form from grocery stores, for example.

[15] The emulsifier and the carrier are first co-processed to form a fine powder, that is, particles smaller than 200 mesh. This fine powder is then added to dry ingredients of a baked good mix.

1161 Effective amounts of the emulsifier are used to provide, for example, the desired product volume, tenderized crumbs, and desired rate of crumb firming. The amount of the emulsifier is within the skill of the art, but is typically 0.05% to 5%, preferably 0.25% to 2.5%, based on the total weight of the formulation. It is noted that the upper levels of many emulsifiers are self-limiting due to detrimental effects from over- emulsifying (see Pyler, E. J.). In addition, many emulsifier levels are regulated in various countries (e. g., in the United States by Code of Federal Regulatins #21.) 171 Effective amounts of the carrier are used to provide the desired dispersibility of the emulsifier as well as improve its functionality. As the carrier can be selected from either minor ingredients (e. g., salts, hydrocolloids, protein sources) or major ingredients (e. g., sugar, flour), the amount of the carrier can range from 0.05 to 75 wt% based on the total formulation weight, though preferably is from 0.5 to 5 wt%.

1181 The ratio of emulsifier to cam'er is typically 1500 : 1 to 1 : 100, preferably 15 : 1 to 1:1.

[191 The co-processing method must be adequate to commingle the emulsifier and carrier.

Commingling means attachment of the emulsifier to the carrier, and/or partial or complete coating of the carrier with emulsifier (or vice-versa) and/or partial or complete encapsulation of the carrier by emulsifier (or vice-versa). Commingling is a more intimate proximity between the emulsifier and carrier than simple dry-blending can achieve. Suitable methods include, but are not limited to, one or more of : spray- drying, co-drying, co-solution, co-precipitation, encapsulation, co-melting, co-milling, homogenization, or any other process involving solvation, heat, pressure and/or shear to provide intimate commingling of the components. Preferably the co-processing method is spray-drying.

[201 The emulsifier may be, but is not limited to, one or more of : lecithins : mono-and diglycerides such as succinylated monoglyccrides, ethoxylated mono-and diglycerides, acetylated monoglycerides, acetoglycerides, lactylated monoglycerides and citric acid esters of monoglycerides ; polyglycerol esters ; polyhydric alcohol esters such as propylene glycol mono-and diesters of fatty acids and polysorbates ; diacetyl tartaric acid esters of fatty acids such as DAT, DATA, TEM, DATEM which are all commonly used abbreviations for diacetyl tartaric acid esters of monoglycerine ; acyl lactylates such as salts of stearoyl-2-lactylates (SSL); and stearyl fumarates.

Preferably, the emulsifier is least one of propylene glycol monoesters, monoglycerides, and sodium stearoyl lactylate.

211 The carrier may be, but is not limited to, one or more of : dried dairy products such as nonfat dry milk (NFDM), dry part-skimmed milk, dry whole milk, caseins, caseinates, whey proteins, dry sweet whey, dry acid whey, reduced-lactose whey, reduced- minerals whey, whey protein concentrates (WPC), whey protein isolates, microparticulated whey protein concentrates and lactose; wheat and grain products and components of such products such as flours, native and/or modified starches, glutens, dextrins and maltodextrins ; sugars such as sucrose, dextrose, fructose and glucose syrup solids; proteins such as dried whole egg, dried egg white, dried egg yolk and egg yolk proteins and soy proteins; thickeners; hydrocolloids ; and gums including biosynthetic gums such as xanthan gum and gellan gum; pectins, galactomannans and seed and exudate gums such as gum arabic, guar gum and locust bean gum; cellulose gels and gums such as carboxymethylcellulose (CMC) and modified gellulose gels and gums; seaweed-derived products such as agars, carrageenans and alginates including modified alginates such as propylene glycol alginate (PGA); edible salts such as sodium chloritie, calcium chloride, trisodium citrate, and calcium lactate ; food acidulants such as citric acid, malic acid, adipic acid, and lactic acid; and preservatives such as sodium benzoate, potassium sorbate, and calcium propionate. Preferably, the carrier is microparticulated whey protein concentrate, 221 The emulsifierlcarrier system is preferably a combination of is least one of propylene glycol monoesters, monoglycerides, and sodium stearyl lactylate, and a microparticulated whey protein concentrate. Suitable emulsifierlcarrier systems are manufactured by CP Kelco Company and sold under the SIMPLESSE 700 series e. g.

SIMPLESSE 720. The SIMPLESSE 700 series is sold as fat substitutes in low fat baked goods and are a microparticulated whey protein concentrate, emulsifier blend.

[231 The present invention is also directed to a method for introducing an emulsifier into a baked good which improves the dispersibility of emulsifier over the current state-of- the-art and, ultimately, improves its functionality. In particular, a suitable emulsifier is commingled with a carrier and then the emulsifierlcarrier are added to the dry ingredients of a cake mix, or other baked product dry mixture.
