Abstract

A method for the recovery of all of the main proteins and enzymes from a liquid milk product, said method comprising the steps of supplying a raw unpasteurized liquid milk product, adding a precipitating agent selected from the group consisting of ethanol and acetone to said raw unpasteurized liquid milk product, mixing said raw unpasteurized milk product and said precipitating agent for a period of time sufficient to form a precipitate, and subsequently recovering said precipitate, said precipitating agent being present in an amount sufficient to precipitate all of said main proteins including non denatured enzymes from said liquid milk product.
A powdered milk product comprising milk proteins separated from a liquid milk product, said powdered milk product being characterized by containing substantially all of the proteins originally present in said liquid milk product including active enzymes.
