ABSTRACT:
A novel method of very efficiently elevating the yield of oligosacchrides containing α-galactosyl, compared with the conventional methods, which comprises treating galactose or a galactose-containing material with a specific α-galactosidase and thus performing a dehydrocondensation reaction at a high substrate concentration. Anti-candida compositions originating in foods, having a high safety and excellent anti-candida effect and not being restricted in the supply, which contain as the active ingredient oligosacchrides obtained by treating galactose or a galactose-containing material with an α-galactosidase and thus performing a dehydrocondensation.
