Patent ID: 8389039

Claim:
A method for preparing a bioactive protein enriched whey product comprising: a. removing>90% of the whey from a solution comprising coagulated milk; b. recovering a curd product from said coagulated milk; c. contacting the curd product with salt to provide salted curd and at least one liquid salt whey stream enriched with bioactive proteins, wherein the salt comprises up to 10% w/w of curd weight; d. recovering at least one liquid salt whey stream enriched with bioactive proteins; and e. concentrating the liquid salt whey stream to provide the bioactive protein enriched whey product; wherein the bioactive protein enriched whey product comprises about 3 to about 20 times the amount of lactoferrin that is typically present in whey or a whey protein product; up to 40 times the amount of TGF-β1 that is typically found in whey or a whey protein product; and up to 10 times the amount of TGF-β2 that is typically found in whey or a whey protein product.
