Document Type and Number:
WIPO Patent Application WO/2024/043297
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for effectively utilizing a by-product generated when a dairy product is produced. Further, the present invention addresses the problem of providing a method for producing galactosyl kojibiose which has an excellent prebiotic capability. The present invention also addresses the problem of providing a composition and a solution which contain galactosyl kojibiose, the composition and the solution retaining, even after subjected to heating, at least 80% of the galactosyl kojibiose. The present invention provides a method for producing an oligosaccharide-containing composition, the method comprising a step of causing glucansucrase acting on a composition comprising sucrose and lactose to obtain a composition containing galactosyl kojibiose. It is preferable to use a lactic acid bacterium that steadily expresses membrane-bound glucansucrase. The present invention provides: a solution containing galactosyl kojibiose and having a pH of less than 7; and a composition containing galactosyl kojibiose, the composition realizing a pH of less than 7 when rendered to a solution having a solid content concentration of 10-80%.
