Abstract From the Canadian patent

This invention relates to a process for the production of a food material from soybean milk. Prior art food materials are generally produced by coagulation of soybean protein which results in poor texture and taste. In this invention, soybean milk is treated with protease, at a pH in the range which does not result in acid coagulation and in the presence of a magnesium salt at a concentration in the range which does not cause substantial magnesium coagulation, to flocculate the protein in the soybean milk. A food material having good texture and high processability is then obtained.
