Abstract:
A process for producing &agr;,&agr;-trehalose, comprising (a) subjecting a glucide raw material to endotype-hydrolysis, under conditions comprising a temperature range of about 50Â° C. to 80Â° C. and a pH range of about 3.5 to 8, to produce a substrate selected from amylose and maltooligosaccharide, (b) transforming, into an &agr;-1, &agr;-1 linkage, the first &agr;-1,4 linkage from the reducing end of said substrate, and (c) hydrolyzing the &agr;-1,4 linkage between the second and third glucose residues from the reducing end of the resultant substrate, to liberate &agr;,&agr;-trehalose therefrom.
