摘要:
Improved aqueous gliadin-containing hairspray formulations are provided which include form about 0.5-10% by weight gliadin dispersed in an aqueous alcohol-containing solvent system at a pH of from about 3-5.5. The preferred formulations have a VOC content of up to about 55% and contain little or no synthetic polymer.
摘要:
Wheat gluten protein-based biodegradable or edible films are produced using aqueous, essentially alcohol-free casting dispersions containing modified wheat protein and a plasticizer. The modified wheat protein is prepared by treating purified naturally occurring wheat protein with a reducing agent (e.g., sodium metabisulfite) in order to reduce the average molecular weight of the wheat protein and to cleave disulfide bonds therein. Such modified wheat gluten protein lowers the viscosity and allows increased solid contents in the casting dispersions, allowing fabrication of improved films.

摘要:
An improved alcohol-free method for fractionating gluten into gliadin and glutenin fractions is provided where an acidic dispersion of gluten is formed with a reducing agent (e.g., sodium metabisulfite) operable for breaking disulfide bonds in the gluten protein. Thereafter, the pH of the dispersion is raised to cause glutenin to precipitate while leaving gliadin suspended in the dispersion. The respective fractions can then be separated by decanting or centrifugation. In preferred processing, the dispersion is reacidified prior to separation in order to achieve a higher degree of separation of the glutenin and gliadin.

A method of forming solid, non-edible biodegradable, grain protein-based articles is provided wherein a grain protein formulation is heated to a maximum temperature of up to about 80.degree. C. to create a substantially homogeneous and flowable mixture which can be formed into biodegradable articles. The formulation includes from about 20-85% by weight of grain protein, from about 5-75% by weight starch, up to about 14% by weight water, from about 10-40% by weight plasticizer, and at least about 0.01 by weight of a reducing agent such as sodium bisulfite for cleaving disulfide bonds present in the grain protein. Optional ingredients such as fillers, fiber, lubricant/mold release agents and colorants can also be used. The formulations can be processed in extrusion or injection molding equipment to create solid articles.
摘要:
Improved compositions for coating paper stock, methods of forming such compositions, and methods of coating paper stock with those compositions are provided. The compositions comprise an aqueous dispersion including therein from about 20-45% by weight filler (e.g., a starch such as wheat starch) and from about 6-18% by weight wheat gluten. Preferably, the gluten is initially modified with a reducing agent so that the average molecular weight of the gluten is less than about 1,000 kDa. The compositions have a viscosity of up to about 2000 cP and a solids content of from about 25-57% by weight, thus making them suitable for high speed coating of paper stock. The finished, coated stock may be conventionally printed to achieve high gloss end products. The compositions are preferably water soluble, thereby greatly facilitating repulping of the coated stock.

Improved aqueous gliadin-containing cosmetic formulations are provided which include form about 0.5-10% by weight gliadin dispersed in an aqueous solvent system together with additional ingredients giving desired end properties. The formulations are preferably selected from the group consisting of hairsprays, hair shampoos and shampoo conditioners, hair styling gels, hair conditioners, instant conditioners, and hair reparatives, as well as sunscreens, shaving creams and bath and shower gels.
摘要:
Gluten protein-based biodegradable or edible films are produced using aqueous, essentially alcohol-free casting dispersions containing modified protein (preferably wheat gluten protein) and a plasticizer. The modified protein is prepared by treating purified naturally occurring wheat protein with a reducing agent (e.g., sodium metabisulfite) in order to reduce the average molecular weight of the wheat protein and to cleave disulfide bonds therein. Such modified wheat gluten protein lowers the viscosity and allows increased solid contents in the casting dispersions, allowing fabrication of improved films using continuous casting techniques and without use of organic solvents.

Conventional food compositions for use in making baked goods and extruded food products are improved by reducing the carbohydrate content. This is done by substituting the conventional flour in whole or in part by a combination of starch that is resistant to amylase digestion and/or from about 1-150 baker's percent of a first proteinaceous ingredient comprising at least about 70% by weight protein, and a second proteinaceous ingredient selected from the group consisting of (i) between about 0.5-100 baker's percent of a wheat protein isolate product; (ii), between about 0.5-100 baker's percent of a wheat protein concentrate product; (iii) between about 0.5-100 baker's percent of a devitalized wheat gluten product; (iv) between about 0.5-20 baker's percent of a fractionated wheat protein product; (v) between about 0.5-20 baker's percent of a deamidated wheat gluten product; (vi) between about 0.5-30 baker's percent of a hydrolyzed wheat protein product; and (vii) any combination of ingredients (i) to (vi).
摘要:
Hydrolyzed jojoba protein is provided which can be used in a variety of cosmetic formulations to enhance the desirable properties thereof. The preferred hydrolyzed jojoba is in the form of an aqueous dispersion containing a mixture of amino acids, peptides and/or protein fractions derived from the hydrolysis of naturally occurring jojoba protein. Cosmetic formulations such as shampoos, shampoo conditioners, hair styling gels, hair conditioners, hair reparatives, bath and shower gels, skin lotions and creams, shaving creams, and sunscreens can be improved by incorporation of hydrolyzed jojoba protein therein.
