Production of crystalline short chain amylose

Disclosed is a process for producing a starch, comprising: treating a feed starch that comprises amylopectin with chain extending 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...

Beschreibung
Zusammenfassung:	Disclosed is a process for producing a starch, comprising: treating a feed starch that comprises amylopectin with chain extending 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; wherein at least 38% by weight of the amylose fragments have a degree of polymerization (DP) of at least 35. Also disclosed are food products and starch products produced by said process.
