Abstract
The present disclosure relates generally to soybean products derived from high protein soybeans, and more specifically to soybean compositions having high protein content and methods of preparing and using such protein enriched soybean compositions. The present disclosure also relates to uses of the protein enriched soybean compositions in food products.
Claims26
A method of producing a protein-enriched soy composition, the method comprising:
- a) providing soybeans having a high protein content;
- b) defatting the soybeans by solvent extraction to produce a defatted soybean composition;
- c) desolventizing the defatted soybean composition to directly produce a defatted desolventized soybean composition that comprises at least about 60% soy proteins on a dry weight basis;
- d) contacting the defatted desolventized soybean composition with polar solvent to remove soluble components to produce a concentrated soy composition, and
- e) desolventizing the concentrated soy composition to produce a protein-enriched soy protein composition that comprises at least about 75% soy proteins on a dry weight basis.
A protein enriched soy composition, comprising at least about 75% soy proteins on a dry weight basis, produced according to a process that:
- (i) uses less water per ton of protein-enriched soy protein composition than a composition with the same protein content prepared using commodity soybeans;
- or
- (ii) uses less electricity per ton of protein-enriched soy protein composition than a composition with the same protein content prepared using commodity soybeans;
- or
- (iii) results in the release of less CO2 into the atmosphere per ton of protein-enriched soy protein composition than a composition with the same protein content prepared using commodity soybeans;
- or
- any combination of (i)-(iii) above.
A protein-enriched texturized soy composition, comprising at least about 75% soy proteins on a dry weight basis, and a content of low molecular weight soluble dietary fiber is less than or equal to about 40% of the total soluble fiber content.
A protein-enriched re-functionalized soy composition, comprising at least about 75% soy proteins on a dry weight basis, and a content of low molecular weight soluble dietary fiber is less than or equal to about 40% of the total soluble fiber content, wherein the protein-enriched re-functionalized soy composition has a protein dispersibility index of at least 70.
