Patent ID: 7189288

Claim:
A process for producing starch that comprises an alpha-amylase resistant component, comprising: (a) providing an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol, wherein the concentration of starch in the feed composition is between about 5% and about 50% by weight, and wherein the pH of the feed composition is between about 3.5 and about 6.5; (b) heating the feed composition in a first heating step to a temperature between about 130–170° C. for about 0.1–3.0 hours; (c) cooling the feed composition to a temperature between about 4–70° C. for about 0.1–6.0 hours; (d) heating the feed composition in a second heating step to a temperature between about 110–150° C. for about 0.1–10.0 hours; (e) separating the starch from the majority of the water and alcohol; and (f) drying the starch.
