This process to yield a resistant starch includes acidifying unmodified starch to an optimal pH with an acid-alcohol mixture that converts the unmodified starch to resistant starch when at a reaction temperature. The acidified unmodified starch is heated to the reaction temperature and maintained there until resistant starch has been obtained while maintaining a whiteness level within a predetermined range.
