WebGelatinization is the irreversible process with respect to the shape of starch molecules. Oppositely, retrogradation is the reversible process in which the solubilized starch chains realign, forming hydrogen bonds by expelling water to form a more crystalline structure. WebMay 3, 2016 · The endothermic process known as gelatinization uses water to plasticize the crystalline starch. As the starch changes phase from crystalline to amorphous, it goes through a “glass” transition, glass being the scientific term for a uniform but amorphous mixture lacking a regular crystal lattice structure. brain infected with rabies
