Abstract
ABSTRACTMembrane‐processed acid whey protein concentrates were studied for their foaming and emulsifying properties in dilute whey protein solutions and in a 30% fat emulsion. Among the compositional factors and physicochemical characters which significantly correlated with foaming and emulsifying properties were protein hydrophobicity, solubility, free‐sulfhydryl content, phosphorus and β‐lactoglobulin concentration. Heptane binding was negatively correlated with foam overrun and foam stability of whey protein solutions, whereas, exposed hydrophobicity was positively correlated with overrun in the whipped topping.
