During this transition, the starch molecules change from a rigid crystalline … Webset temperature profile. Starch which has been pregelatinised absorbs water more readily, causing the grains to swell and increasing the paste viscosity at low temperatures. A rapid increase in viscosity is observed at the gelatinisation temper ature as amylose diffuses from the granules resulting in formation of a gel.[17]
