The invention provides a process for producing a low-fat whey protein which comprises forming an aqueous system containing whey protein in an amount not greater than 1.5% by weight and having an ash:protein ratio not exceeding 0.08:1, adjusting the pH of the system to a value in the range of from 4.0 to 4.8 and separating the resultant precipitate from the aqueous system by air flotation in the presence of isinglass. The process produces two products, a low-fat whey protein and a high-fat whey protein, either or both of which may be further processed to form dried powders. |
