Abstract: A process for preserving baked goods takes advantage of the discovery that a form of modified whey characterized by a calcium content of at least 3%, protein content of from 10 to 20%, and a phospholipid content of at least 2%, has high antimicrobial activity, particularly, antimycotic activity. Baked flour-containing foods are formulated to contain sufficient amounts of the modified whey to provide a desired antimicrobial activity, e.g., from about 2 to about 10% of the modified whey will improve the stability of baked goods having moisture contents as high as 50%.

Abstract: A modified whey protein isolate having the ability to fully replace egg whites in many food applications requiring foaming is prepared by a process which involves heat treating to obtain a unique balance of overrun and foam stability properties. The process entails heating an aqueous solution of whey protein isolate at from 70 to 85° C., and can include holding ath this temperature and pH adjustment prior to heating to obtain the desired properties. Food mixes employing the modified whey protein isolate and processes for making food products employing the modified whey protein isolate are also provided.

Abstract: A regimen for calcium supplementation takes advantage of the discovery that a calcium supplement containing modified whey characterized by a calcium content of at least 3%, protein content of from 10 to 20%, and a phospholipid content of at least 2%, is of high biological value. It can be accomplished with calcium-supplemented foods that administer foods containing sufficient amounts of the modified whey to provide at least 5% of the amount of calcium required for complete nutrition on a daily basis. The regimen can benefit humans and domestic pets, in particular. More preferred levels of administration will provide at least 10% and in some cases at least 25% of the RDA for calcium for the subject.
