Abstract
Disclosed is a novel non-reducing oligosaccharide with neotrehalose structure represented by the general formula as shown by: ##STR1## The oligosaccharide is obtainable by exposing an aqueous solution containing neotrehalose to a saccharide-transferring enzyme, and has a superior stability, reduced sweetness, appropriate viscosity, no susceptibility to crystallization and less fermentability. These features make it very useful in various compositions including foods, beverages, cosmetics and pharmaceuticals.
Claims4
A process for producing a non-reducing oligosaccharide having the formula:
- ##STR7## where "n" and "m" are 0 or more integers, and their total number (n+m) is at least 1
- said method comprising:
- (a) exposing an aqueous solution which contains neotrehalose and an .alpha.-glucosyl saccharide either to the action of a saccharide-transferring enzyme or to the action of a saccharide-transferring enzyme and also a hydrolase in this order to form said non-reducing oligosaccharide;
- and
- (b) recovering said non-reducing oligosaccharide.
