Abstract: Bread and similar wheat flour-based products are provided which exhibit reduced toughness when subjected to microwave heating. The products are prepared from wheat flour-based, leavened doughs which have adjusted gliadin:glutenin ratios of from about 1.1-2.3, such ratio adjustment is preferably accomplished by the addition of a gliadin-rich preparation into the starting doughs, typically at levels of from about 1-6% (fwb).

Abstract: 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.

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.
