MODIFICATION OF SOYBEAN OLIGOSACCHARIDE

摘要

PURPOSE:To decrease sucrose content in soybean oligosaccharide and to increase the content of raffinose, etc., effective as a bifidus-proliferation factor, by treating soybean oligosaccharide with alpha-galactosidase. CONSTITUTION:Soybean oligosaccharide is treated with an alpha-galactosidase (e.g. originated from Streptococcus bovis) preferably at a substrate concentration of 50wt.% at pH 5-8 and treating temperature of 30-70 deg.C usually for 20-40hr.
