Abstract: Food product comprising a peptide, said peptide being characterized by having a number of amino acids from 6 to 20, and wherein the peptide is substantially water-insoluble at 20° C. and a pH of 6.5, as evidenced by a measurable turbid appearance if 10 mg of the peptide is mixed with 10 ml of de-mineralised water at 20° C. and pH 6.5 and wherein the net charge of said peptide is 0 as determined by summation of the charges of the individual amino acids of said peptide at pH 6.5 and wherein if the peptide is a hexa-peptide 6 amino acids of said peptide are selected from the group consisting of A, V, L, I, P, W, F and M.

Abstract: Food product comprising a peptide, said peptide being characterized by having a number of amino acids from 4 to 20, and having a net positive charge of 1 or higher as determined by summation of the charges of the individual amino acids of the peptide at pH 6.5, with the proviso that the peptide is not a ?-peptide.
