Abstract
Abstract An aqueous foamable composition is provided comprising an admixture of alcohol selected from the group consisting of methanol, ethanol, and isopropanol present in said composition in an amount of from about 0.5 to 35% by volume, an aqueous solution of whey protein isolate or concentrate present in an amount of at least 5% by volume and having a whey protein isolate or concentrate solids content of from about 1 to 10% by weight, and a fat present in a volume ratio of fat:aqueous whey solution of from about 1:1 to about 13:1, said composition having a pH of at least 10.5.
