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.

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： 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.

摘要： Hydrothermal processes are provided for preparing hybrid proteins containing altered SS/SH bonds, thereby yielding hybrid proteins having enhanced functional properties. The processes involve steam treatment of an aqueous protein-containing slurry containing at least two different proteins in a jet cooker (16) or similar device in order to heat shock and thereby alter the conformation of some of the proteins, followed by relatively rapid cooling to cause formation of the desired hybrids. Plant and animal proteins may be processed, and the starting slurry can be pH-modified and/or supplemented with one or more additional ingredients (e.g., salts, phosphates, fatty acids, polysaccharides, alcohols, aromatic compounds). The hybrid proteins are useful as food ingredients (e.g., solubility, wetability, dispersibility, foaming, emulsification, viscosity, gelation or thickening agents).

摘要： To prepare a biodegradable plastic, biodegradable materials such as starches and a non-biodegradable polymer such as a polystyrene, polyurethane, polyethylene, polypropylene, or polycarbonate are treated: (1) under heat, pressure and reagents to break the polymers; and (2) by adding to them an oxidizing agent. This treatment forms and/or makes available reactive groups for bonding: (1) on the biodegradable material groups such as aldehyde or hydroxyl groups in the case of the carbohydrates and amine groups in the case of proteins and certain other compounds such as urea; and (2) on the non-biodegradable plastic groups such as aldehydes, methyl, propyl, ethyl, benzyl or hyroxyl groups. In one embodiment, plastic and starch are processed in an extruder by: (1) mixing a starch in a range of between 15 percent and 80 percent, an oxidizing agent and an agent to break up the starch and the plastics; and (2) subjecting the combination to sufficient heat and/or pressure to break the plastic into shorter chains and bond monosaccharides to monomers from the non-biodegradable polymer.
