摘要

A process for producing starch comprising a resistant alpha-amylase component, starch, a food product, and a method for making a starch resistant to alpha-amylase. One process for producing an enzyme resistant starch uses the feed of an aqueous composition which comprises (1) starch containing at least about 50% by weight of amylose, (ii) water, and (iii) alcohol. The concentration of starch in the fed composition is between about 5% and about 50% by weight, and the pH of the fed composition is between about 3.5 and about 6.5, in a first heating step, the fed composition is heated to a temperature between about 130-170 ° C for about 0.1 - 3.0 hours. The fed composition is cooled to a temperature between about 4-70 ° C for about 0-6.0 hours. In a second heating step, the fed composition is heated at a temperature between about 110-150 ° C for about 0.1-10.0 hours. Starch is separated from most water and alcohol and is dried.
