PRODUCTION OF BIFIDUS BACTERIUM PROLIFERATION SUBSTANCE

摘要

PURPOSE:To produce a bifidus bacterium proliferation substance useful in food and pharmaceutical industries, etc., with simple operation in high efficiency, by using defatted soybean or extraction residue of soybean with a fat-dissolving solvent as a starting raw material and extracting the material with an aqueous solution of an alcohol. CONSTITUTION:Defatted soybean or residue of flaky soybean extracted with kexane, etc., to remove fat soluble substance is added with 5-10pts.wt. of an aqueous solution of ethyl alcohol or methyl alcohol having a concentration of 20-60V/V%. The mixture is stirred at room temperature and/or under heating at about 60 deg.C to extract a bifidus-proliferation substance. Insoluble components are removed from the extracted liquid and the obtained supernatant liquid is distilled to evaporate the alcohol. The concentrated liquid is dried e.g. by spray drying.
