Explanation:
Detailed explanation-1: -Starch granules are insoluble in cold water. When starch is heated in water, granules absorb water and swell. The absorption of water by amorphous regions within the granules destabilizes their crystalline structure, resulting in the loss of birefringence, which is one definition of gelatinization ( 9−11).
Detailed explanation-2: -Cold water-solubility The native starch solubility was negligible ( 4 %) in cold water at 25 °C; however, it increased significantly ( 23 %) when starch suspension was prepared at 35 °C.
