CA 2621340
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.
L'invention concerne un procédé servant à produire un amidon et consistant à traiter un amidon alimentaire contenant de l'amylopectine par une glucanotransférase afin de produire un amidon à chaîne étendue et à traiter cet amidon à chaîne étendue par une enzyme de déramification afin de produire un produit d'amidon contenant des fragments d'amylose. Au moins environ 38 % en poids des fragments d'amylose ont un degré de polymérisation d'au moins 35 environ.
