Abstract
A process for producing an enzyme-resistant starch uses an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol. The concentration of starch in the feed composition is between about 5% and about 50% by weight, and the pH of the feed composition is between about 3.5 and about 6.5. In a first heating step, the feed composition is heated to a temperature between about 130–170° C. for about 0.1–3.0 hours. The feed composition is cooled to a temperature between about 4–70° C. for about 0.1–6.0 hours. In a second heating step, the feed composition is heated to a temperature between about 110–150° C. for about 0.1–10.0 hours. The starch is separated from the majority of the water and alcohol and is dried.
