1. Field of the Invention
The present invention generally pertains to improved bakery products (particularly wheat-containing bakery products and doughs) having higher protein and lower carbohydrate contents when compared with similar, more traditional bakery products and doughs. Products according to the invention comprise a first protein source along with a second proteinaceous ingredient and, optionally, a quantity of resistant starch.
2. Description of the Prior Art
The rise in popularity of high-protein diets has increased the demand for high-protein, and consequently, low carbohydrate substitutes for foods, particularly bakery products, which typically contain a significant amount of carbohydrate. Many attempts have been made to decrease the carbohydrate level in these products by substituting a protein source for flour in the product's formulation. While this approach has solved the problem of providing a high-protein, low-carbohydrate product, generally, the resulting product does not have the handling characteristics, loaf volume, crumb grain, texture, or flavor of a traditional bakery product.
For example, if vital wheat gluten is used in large amounts in the production of bread dough, the dough will be too strong or bucky and difficult to handle during mixing, dividing, sheeting, and molding. Also, high levels of protein such as soy protein may adversely affect flavor and give unacceptable volume and crumb grain properties.
Therefore, there exists a real need in the art for a high-protein, low-carbohydrate bakery product which closely resembles a traditional bakery product. The bakery product should exhibit dough handling, machinability, loaf volume, crumb grain, and flavor characteristics similar to those of a traditional bakery product.
The present invention overcomes the above problems and provides a high-protein, low-carbohydrate bakery product which exhibits dough handling properties, loaf volume, crumb grain, and flavor characteristics similar to those of a traditional bakery product. As used herein, the term “high-protein, low-carbohydrate bakery product” refers to compositions which contain higher protein and lower carbohydrate amounts relative to more traditional-type products. The term “bakery product” includes, but is not limited to leavened or unleavened, traditionally flour-based products such as white pan and whole wheat breads (including sponge and dough bread), cakes, pretzels, muffins, doughnuts, brownies, cookies, pancakes, biscuits, rolls, crackers, pie crusts, pizza crusts, hamburger buns, pita bread, and tortillas.
In addition to comprising a quantity of flour (particularly wheat flour), preferred bakery products (including doughs) according to the invention comprise from about 1-150 baker's percent of a first proteinaceous ingredient (preferably from about 5-60 baker's percent) comprising at least about 70% by weight protein and a second proteinaceous ingredient (preferably different from the first ingredient) selected from the group consisting of:
As used herein, the term “baker's percentage” means the weight percent taken on a flour basis, with the weight of flour present in the product being 100%.
Furthermore, all protein weight percentages expressed herein are on a N×6.25, dry basis, unless otherwise specified.
Wheat protein isolates are generally derived from wheat gluten by taking advantage of gluten's solubility at alkaline or acidic pH values. Wheat gluten is soluble in aqueous solutions with an acidic or alkaline pH and exhibits a classical “U-shaped” solubility curve with a minimum solubility or isoelectric point at pH 6.5-7.0. By dissolving the gluten, proteins can be separated from non-protein components by processes like filtration, centrifugation, or membrane processing followed by spray drying. Alternatively, wet gluten from wet processing of wheat flour can be repeatedly kneaded, water washed, and dewatered to get rid of contaminating starch and other non-protein components, and subsequently flash dried. These techniques yield a wheat protein isolate product with elevated protein content, at least about 85% by weight, more preferably at least about 90% by weight (on an N×6.25, dry basis). Wheat protein isolates are less elastic but more extensible than wheat gluten. Examples of preferred wheat protein isolates include Arise™ 3000, Arise™ 5000, and Arise™ 6000 available from MGP Ingredients, Inc., Atchison, Kans.
Wheat protein concentrates are proteinaceous compositions which preferably have protein contents of at least about 70% by weight, and preferably at least about 82% by weight (N×6.25, dry basis). Wheat protein concentrates may be of different varieties manufactured by a number of different methods. Vital wheat gluten is one type of wheat protein concentrate that has a protein content of at least about 82% by weight (N×6.25, dry basis). Vital wheat gluten is a viscoelastic protein manufactured by a flash drying method. Additional types of wheat protein concentrates are manufactured by dispersing wet gluten in an ammonia solution followed by spray drying. These wheat protein concentrates exhibit lesser viscoelastic properties than vital wheat gluten but tend to be more extensible. Examples of the latter type of wheat protein concentrates include FP 300, FP 500, FP 600, and FP 800 available from MGP Ingredients.
Wheat gluten can be devitalized (or rendered non-vital) by the application of moisture, heat, pressure, shear, enzymes, and/or chemicals. Devitalized gluten is characterized by denaturation of proteins where structural changes occur and certain bonds are broken resulting in a product that is non-cohesive and lacks viscoelasticity. Typical processing equipment used to carry out this devitalization include extruders, jet-cookers, and drum-driers. For example, wheat gluten may undergo extrusion processing to produce a texturized product which does not exhibit the same viscoelastic properties of typical wheat gluten. In other words, the devitalized gluten does not form a rubbery and/or extensible dough when hydrated. Devitalized wheat gluten preferably comprises at least about 60% by weight protein, and more preferably at least about 70% by weight (N×6.25, dry basis). Examples of devitalized wheat gluten for use with the present invention are Wheatex™ 16, Wheatex™ 120, Wheatex™ 240, Wheatex™ 751, Wheatex™ 1501, Wheatex™ 2120, Wheatex™ 2240, Wheatex™ 2400, Wheatex™ 3000, Wheatex™ 6000, and Wheatex™ 6500 available from MGP Ingredients.
Wheat gluten is a binary mixture of gliadin and glutenin. These components can be separated by alcohol fractionation or by using a non-alcoholic process (as disclosed in U.S. Pat. No. 5,610,277) employing the use of organic acids. Gliadin is soluble in 60-70% alcohol and comprises monomeric proteins with molecular weights ranging from 30,000 to 50,000 daltons. These proteins are classified as alpha-, beta-, gamma-, and omega-gliadins depending on their mobility during electrophoresis at low pH. Gliadin is primarily responsible for the extensible properties of wheat gluten. Glutenin is the alcohol insoluble fraction and contributes primarily to the elastic or rubbery properties of wheat gluten. Glutenin is a polymeric protein stabilized with inter-chain disulfide bonds and made up of high-molecular weight and low molecular weight subunits. Generally, glutenin exhibits a molecular weight exceeding one million daltons. Preferred fractionated wheat protein products comprise at least about 85% by weight protein, and more preferably at least about 90% by weight for gliadin and about 75% by weight protein, and more preferably at least about 80% by weight for glutenin, all proteins expressed on N×6.25, dry basis.
Deamidated wheat protein products may be manufactured according to a number of techniques. One such technique is to treat wheat gluten with low concentrations of hydrochloric acid at elevated temperatures to deamidate or convert glutamine and asparagine amino acid residues in the protein into glutamic and aspartic acid, respectively. Other techniques include treating wheat gluten with an alkaline solution or with enzymes such as transglutaminase. This modification causes a shift in the isoelectric point of the protein from about neutral pH to about pH 4. This signifies that the deamidated wheat protein product is least soluble at pH 4, but is soluble at neutral pH. Deamidated wheat protein products preferably comprise at least about 75% by weight protein, and more preferably at least about 83% by weight (N×6.25, dry basis). An example of a deamidated wheat protein product for use with the present invention is WPI 2100 available from MGP Ingredients.
Hydrolyzed wheat protein products are manufactured by reacting an aqueous dispersion of wheat gluten with food-grade proteases having endo- and/or exo-activities to hydrolyze the proteins into a mixture of low-molecular weight peptides and polypeptides. The hydrolyzed mixture is then dried. Hydrolyzed wheat protein products generally exhibit a water solubility of at least about 50%. Hydrolyzed wheat protein products preferably have protein contents of at least about 70% by weight, more preferably at least about 82% by weight (on an 6.25×N, dry basis). Examples of hydrolyzed wheat protein products for use in the present invention include HWG 2009, FP 1000, and FP 1000 Isolate, all available from MGP Ingredients.
Preferably, high-protein bakery products according to the invention comprise from about 1-150 baker's percent of the first proteinaceous ingredient, more preferably from about 5-60 baker's percent. Preferred first proteinaceous ingredients comprise at least about 70% by weight protein and more preferably at least 82% by weight protein (6.25×N, dry basis). Exemplary preferred first proteinaceous ingredients include vital wheat gluten, soy protein concentrate, soy protein isolate, whey protein, sodium caseinate, nonfat dry milk, dried egg whites, wheat protein isolate, wheat protein concentrate, devitalized wheat gluten, fractionated wheat protein, deamidated wheat gluten, hydrolyzed wheat protein, and mixtures thereof.
Bakery products according to the present invention may be chemically leavened or yeast leavened. Preferred chemical leavening agents include sodium bicarbonate, monocalcium phosphate, sodium aluminum phosphate, sodium aluminum sulfate, sodium acid pyrophosphate, dicalcium phosphate, potassium acid tartrate, and glucono-delta-lactone.
Preferred yeast-leavened bakery products and dough have a total protein content from about 5-35% by weight, and more preferably from about 20-28% by weight. Preferred chemically leavened bakery products and dough have a total protein content from about 4-18% by weight, more preferably from about 6-12% by weight.
Preferably, bakery products made in accordance with the present invention comprise an amount of resistant starch. The resistant starch may be used in place of at least a portion of the flour which comprises traditional bakery products, thereby effectively reducing the “net” carbohydrate total of the bakery product. As explained in further detail below, resistant starch is generally not digestible thereby exhibiting characteristics which are similar to those of dietary fiber.
In 1987 Englyst and Cummings at the MRC Dunn Clinical Nutrition Center in Cambridge, UK, proposed a classification of starch based on its likely digestive properties in vivo. They also devised in vitro assay methods to mimic the various digestive properties of starch. Three classes of dietary starch were proposed:
(1) Rapidly Digestible Starch (RDS). RDS is likely to be rapidly digested in the human small intestine; examples include freshly cooked rice and potato, and some instant breakfast cereals.
(2) Slowly Digestible Starch (SDS). SDS is likely to be slowly yet completely digested in the small intestine; examples include raw cereal starch and cooked pasta.
(3) Resistant Starch (RS). RS is likely to resist digestion in the small intestine. RS is thus defined as the sum of starch and starch degradation products not likely to be absorbed in the small intestine of healthy individuals. RS can be subdivided into four categories depending on the cause of resistance (Englyst et al., Eur. J. Clin. Nutr. 46(suppl 2):533, 1992; Eerlingen et al., Cereal Chem. 70:339, 1993).
RS1. Physically inaccessible starch due to entrapment of granules within a protein matrix or within a plant cell wall, such as in partially milled grain or legumes after cooling.
RS2. Raw starch granules, such as those from potato or green banana, that resist digestion by alpha-amylase, possibly because those granules lack micropores through their surface.
RS3. Retrograded amylose formed by heat/moisture treatment of starch or starch foods, such as occurs in cooked/cooled potato and corn flake.
RS4. Chemically modified starches, such as acetylated, hydroxypropylated, or cross-linked starches that resist digestion by alpha-amylase. Those modified starches would be detected by the in vitro assay of RS. However, some RS4 may not be fermented in the colon.
RS1, RS2, RS3 are physically modified forms of starch and become accessible to alpha-amylase digestion upon solubilization in sodium hydroxide or dimethyl sulfoxide. RS4 that is chemically substituted remains resistant to alpha-amylase digestion even if dissolved. RS4 produced by cross-linking would resist dissolution.
Highly cross-linked wheat starches belonging to RS4 category may be manufactured by processes disclosed in U.S. Pat. No. 5,855,946 and U.S. Pat. No. 6,299,907. Typical total dietary fiber content (AOAC Method 991.43) of these RS4 products can range from 10% to greater than 70%. Examples of preferred RS4 products for use with the present invention are the FiberStar series, for example FiberStar 70, available from MGP Ingredients.
Preferred products according to the present invention comprise from about 5-120 baker's percent of a resistant starch, and more preferably from about 20-90 baker's percent.
Table 1 summarizes broad and preferred ranges of the various second proteinaceous ingredients for use in products according to the present invention. The various weight percentages listed are on a flour weight basis (or baker's percent).
Preferred products made in accordance with the invention exhibit several nutritional and functional benefits. The products are a good source of nutrition due to their elevated protein content and because of a reduced total caloric contribution from carbohydrates. The various protein sources provide a good complement of amino acids. In addition to being an excellent source of fiber (attributable to the presence of resistant starch), the products exhibit a low glycemic index. As stated previously, the inventive formulation improves dough handling and machinability, decreases dough buckiness, and improves product flavor.
The following examples set forth preferred products in accordance with the present invention. It is to be understood, however, that these examples are provided by way of illustration and nothing therein should be taken as a limitation upon the overall scope of the invention.
For Examples 1-11, the following mixing and baking procedures were used. All dry ingredients were blended together until thoroughly incorporated. All liquid ingredients were added and the dough mixed for one minute on low speed using a Hobart A200 mixer (Hobart Corp.) With a spiral dough hook, and then mixed for 2-2.5 minutes on high speed. The mixing was relatively minimal to prevent excessive development and excessively tough and rubbery bread. The dough scaling weight followed a pan factor of 2.00-2.05. The dough scaling weight (in ounces) was determined by dividing the area (in square inches) of the top of the bread pan by the pan factor. The dough was proofed at 110° F. with a relative humidity of 85%. The dough was baked at 390° F. for 37-42 minutes.
