摘要：
Disclosed is a method of preparing a yoghurt having at least 7% (w/v) protein by mixing a dried whey protein concentrate (WPC) or whey protein isolate (WPI) with a milk comprising casein and acidifying the yoghurt milk to a pH of 3.8-5.5 wherein the WPC or WPI is prepared by a method comprising: (a) Providing an aqueous WPC or WPI solution having a protein concentration of 15-50% (w/v), at a pH of 4.7-8.5 (b) Heat treating the solution to more than 50 degrees celcius, for a time that allow protein denaturation to occur the heat treating comprising heating the solution while under conditions of turbulent flow. (c) At the end of the heat treatment, transferring the heat treated material promptly to a drier and (d) Drying the heat-treated WPC or WPI. Wherein the heat-treated WPC or WPI is not subjected to a mechanical shear process prior to drying other than where liquid is converted into droplets to facilitate drying.
