Abstract

Abstract A protein food product is described, together with a process for making it. Whey protein derived from milk is adjusted to a pH of 6 to 9 and coagulated by heat, thereby giving a firm, non-brittle material which is useful as a protein food in its own right, or as a matrix for composite products, or in the manufacture of pieces resembling meat offals such as kidney, to improve the texture of meat-containing mixes, for example of sausage type, and for other food products, all of which are useful as protein foods for animals and also for human beings.

Claim 6
Dependent Claim 56 words
A food product according to claim 2 comprising 10 to 40% said whey protein, an effective amount up to 20% other foodstuff, selected from the group consisting of meat, meat by-products, cereals, flavorants and colorants, 10 to 40% humectant and 20 to 45% moisture, and having a water activity in the range of 0.75 to 0.85.
Claim 7
Independent Claim 87 words
A method of making a firm, coherent gel protein food product comprising the steps of: forming a mix comprising an aqueous solution or dispersion of 15 to 70% by weight whey protein, said whey protein having been separated from whey under acidic conditions, and 30 to 85% moisture; adjusting the pH value of said mix to within the range of 6 to 9; and therafter heating said mix at pH 6 to 9 at a temperature and for a period of time sufficient to coagulate said protein.
Claim 8
