Abstract
Abstract This invention relates to a composition for promoting growth of Bifidobacteria containing as effective constituent an oligosaccharide represented by the general formula Gal-(gal)n-Glc, wherein Gal denotes a galactose residue, Glc a glucose residue and n an integer of 1 to 4. This invention further relates to a method for manufacture of the material for promoting growth of Bifidobacteria characterized in that lactose or a lactose-containing material is treated with beta -galactosidase produced by Aspergillus oryzae.

Claim 1
Independent Claim

A composition for promoting growth of bifidobacteria consisting essentially of a mixture of oligosaccharides represented by the general formula Gal-(Gal) n -Glc, wherein Gal denotes a galactose residue, Glc a glucose residue and n an integer of 1 to 4, and in which the galactose-galactose linkage is β-1,3, β-1,4 or β-1,6 with the β-1,6 linkage being predominant and the galactose-glucose linkage is β-1,3, β-1,4 or β-1,6 with the β-1,4 linkage being predominant; said oligosaccharides being produced by reacting lactose or a lactose-containing material with β-galactosidase produced by Aspergillus oryzae at a temperature and time sufficient to produce said composition.
