Abstract
A method for the production of resistant starch comprising acidifying unmodified starch to an optimal pH with an acid-alcohol mixture to convert the unmodified starch to resistant starch when at a reaction temperature, heating the acidified unmodified starch to about the reaction temperature, and maintaining the acidified unmodified starch close to about the reaction temperature until the resistant starch has been obtained while maintaining a whiteness level within a predetermined range. Resistant starches and food products manufactured therefrom are also disclosed.
Claims25
A method of producing dextrinized resistant starch comprising:
- acidifying unmodified starch to a selected pH of about 1 to about 4 with an acid-alcohol mixture, wherein the pH is selected to convert the unmodified starch to dextrinized resistant starch when at a reaction temperature in the range of 140° C. to 180° C.;
- heating the acidified unmodified starch to within the reaction temperature range;
- and
- maintaining the acidified unmodified starch within the reaction temperature range until a maximized yield of dextrinized resistant starch has been obtained while maintaining a whiteness level of at least 65.
