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 caseinates. 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.
