METHOD FOR MANUFACTURING MODIFIED WHEY COMPOSITION, MODIFIED WHEY COMPOSITION, AND METHOD FOR MANUFACTURING CALCIUM-ENRICHED MODIFIED WHEY COMPOSITION

摘要

The present invention relates to a method for manufacturing a modified whey composition, the method having a liquid preparation step of preparing a raw material whey liquid using a whey composition containing whey protein, and a heating step of subjecting the raw material whey liquid to a heat treatment, wherein the liquid preparation step includes a treatment of adding an alkali to the whey composition, the pH of the raw material whey liquid is from 6.8 to 8.0 and the protein concentration in the liquid is not more than 1.3% by mass, the calcium content of the raw material whey liquid that is subjected to the heat treatment is from 400 to 700 mg/100 g of solids, and the heat treatment is performed under conditions of 80 to 150°C for a period of 30 minutes to 1 second.
