Gelatin is a natural macromolecule material extracted by the thermal hydrolysis of collagen. Gelatin raw materials are pretreated with either acid or alkali to allow the swelling of collagen in order to increase the efficiency of gelatin extraction. Swelling of collagen and its subsequent solubiliza...
