Abstract
This invention relates to the production of resistant starch. Preferably, this invention relates to the production of resistant starch comprising selecting a reaction temperature, acidifying unmodified starch to a pH, wherein the pH is optimum to convert the unmodified starch to resistant starch when at the 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 maximum yield of resistant starch has been obtained while maintaining a whiteness level between about 65 and about 100.
Claims17
A method of producing resistant starch comprising:
- (a) selecting a reaction temperature of 140° C. to 180° C.;
- (b) acidifying unmodified starch to a selected pH of about 1 to about 4 with hydrochloric acid, wherein said selected pH is optimum to convert said unmodified starch to resistant starch when at said reaction temperature;
- (c) heating said acidified unmodified starch to said reaction temperature;
- and
- (d) maintaining said acidified unmodified starch close to said reaction temperature until a maximized yield of resistant starch has been obtained while maintaining a whiteness level of at least 65.
