PRODUCTION OF SOYBEAN OLIGOSACCHARIDE

摘要

PURPOSE:To obtain high-purity soybean oligosaccharide useful as promoter for proliferating Bifidobacterium or sweetening agent having low sweetness in high yield by subjecting a soybean whey solution to heat treatment and then controlling the pH of the solution using phosphoric acid and removing the resultant precipitate. CONSTITUTION:A solution of soybean whey (obtained by adding an acid, etc., to bean milk obtained from soybean or defatted soybean to solidify a protein and removing the solidified protein) is subjected to heat treatment at 70-110 deg.C (preferably at 80-100 deg.C) and controlled to <=pH3 using phosphoric acid and the resultant precipitate is subjected to centrifugal separation to provide the objective soybean oligosaccharide.
