Abstract: The 7S and 11S proteins of vegetable proteins may be effectively fractionated and isolated by selectively extracting 7S proteins from an isoelectrically precipitated mixture of 7S and 11S protein in the presence of water-soluble salts. The initial 7S extraction is typically conducted at a pH 5.0-5.6. An enriched 11S fraction is recovered by separating the water-insoluble 11S protein from the water-soluble enriched 7S extract.

Abstract: It has been discovered that the combination of certain polyvalent metal ions with certain proteinaceous foaming agents will significantly enhance the efficacy of proteinaceous foaming compositions. The present invention affords the means for achieving significantly improved protein foam from vegetable protein hydrolyzates which normally fail to possess the foaming efficacy of conventional proteinaceous foam agents such as egg albumen and ca?einates. The improved foamed products may be obtained by employing a combination of polyvalent ions such as calcium and zinc with enzymatically hydrolyzed soy protein whipping agents which are characterized as being soluble throughout the pH 4 to 7 range. The proteinaceous foaming composition may be utilized for a variety of industrial and food applications. The present foaming compositions are particularly useful in providing coated paper products.
