ABSTRACT:
A process for preparing a separated soybean protein, by the steps of preparing an aqueous slurry of defatted soybeans, removing water-insoluble components from the slurry and collecting a protein component from the obtained soybean milk, wherein in preparing an aqueous slurry of defatted soybeans, an antioxidant and a chelating agent are added, or at least one member selected from the group consisting of ascorbic acid, erythorbic acid and their salts is added in an amount of at least 0.1 part by weight per 100 parts by dry weight of the defatted soybeans. The process gives a soybean protein which shows improved resistance to discoloration when heat-treated at a high temperature.
