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.
Claims10
Branched starch having 6-α-maltosyl- and/or 6-α-maltotetraosyl-branched structure(s).
A process for producing branched starch having 6-α-maltosyl- and/or 6-α-maltotetraosyl-branched structure(s), comprising the steps of:
- (a) forming branched starch having 6-α-maltosyl- and/or 6-α-maltotetraosyl-branched structure(s) by allowing a cyclic maltosylmaltose-forming enzyme to act on liquefied starch and/or partial starch hydrolysate;
- and
- (b) collecting the formed branched starch having 6-α-maltosyl- and/or 6-α-maltotetraosyl-branched structure(s).
