Process for making whey proteins having improved thermal stability in beverage applications at neutral pH

摘要

The present invention is directed to a method for producing a thermal stable whey protein beverage comprising: (a) providing an aqueous solution of at least 2% (w/w) whey proteins and having a neutral pH; then (b) heating the aqueous solution of whey proteins; then (c) cooling the aqueous solution of whey proteins; then (d) adding at least one mineral salt at a neutral pH; and then (e) heating the aqueous solution of whey protein to produce a thermal stable whey protein beverage. The present invention is further directed to a method for producing a thermal stable whey protein beverage under aseptic processing conditions or pasteurization or ultrapasteurization conditions comprising: (a) providing an aqueous solution of at least 2% whey proteins and having a neutral pH; then (b) heating the aqueous solution of whey proteins; then (c) cooling the aqueous solution of whey proteins; then (d) adding at least one mineral salt to produce a thermal stable whey protein beverage. The present invention is also directed to a method for producing a thermal stable whey protein beverage comprising adding at least one anionic polysaccharide. Additionally, the present invention provides thermal stable whey protein beverages made by the methods provided herein.
