The present invention relates to a process in which an aqueous solution of proteins is subjected to hydrolysis, the product of hydrolysis is subjected to a heat treatment to denature the proteins which it contains and, finally, the proteins are eliminated by ultrafiltration. The ultrafiltration permeate constitutes the purified protein hydrolysate.

Process for the preparation of a purified protein hydrolysate

A process for eliminating the flatulent sugars present in soya which comprises preparing an aqueous soya suspension containing from 5 to 45% by weight of dry matter, inoculating the suspension thus prepared with at least one strain of Saccharomyces uvarum which has reached the state of growth on a medium containing at least one sugar having at least one .alpha.-D-galactopyranosyl bond and fermenting the suspension under anaerobic conditions for at least 8 hours at a temperature of from 15.degree. to 50.degree. C.
