Production of crystalline short chain amylose

A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, and treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments. At least about 38% b...

Zusammenfassung:A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, and treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments. At least about 38% by weight of the amylose fragments have a degree of polymerization (DP) of at least about 35.
