(57) [Summary] [Purpose] To provide a new food / beverage material having strong bifidobacteria growth-promoting activity. [Structure] The following properties are synthesized by a dehydration condensation reaction of α-galactosidase using a substance containing galactose as a raw material: 1) As a result of an assimilation test using Bifidobacterium bifidum, which is an intestinal bacterium, Pept containing the oligosaccharide composition at a concentration of 0.5% On-Yeast-Fildes solution (PYF) shows an assimilating strength such that the pH of the medium is 5.5 or less; 2) Crystal precipitation is observed even when an 80% (W / W) aqueous solution is left at 25 ° C for 24 hours or more. A food / beverage material containing an α-galacto-oligosaccharide composition having: [Effect] Since it is low in caries and anti-cariogenic and effective as a growth factor for bifidobacteria, it can be used in foods and drinks for the purpose of promoting health. |
