Abstract
An object of the present invention is to provide a novel starchy substance having a retrogradation-resistance, a process for producing the starchy substance efficiently from a material starch by enzymatic reaction, and uses thereof. The present invention attains the above object by providing branched starch having 6-α-maltosyl- and/or 6-α-maltotetraosyl-structure(s) with a marked retrogradation-resistance, a process for producing the branched starch without lowering the molecular weight of material starch, and uses thereof.
Claims2
A process for producing a modified branched starch, which comprises the steps of:
- (a) allowing β-amylase to act on a branched starch, having a 6-α-maltosyl- and/or 6-α-maltotetraosyl-branched structures at the non-reducing ends of said branched starch, to hydrolyze said branched starch from its non-reducing ends by maltose unit to form a modified branched starch containing maltose;
- and
- (b) collecting the formed modified branched starch.
