To make gelatin, collagen rich materials (mostly bovine hide or porcine skins) are cleaned and treated with dilute alkaline, or acid and heat to denature (untangle) the collagen into hot water-soluble proteins. The extract is purified and dried to form the gelatin powder.elatin is a hot water soluble protein extracted from collagen. Individual collagen monomeric proteins have molecular weights of between 95,000 and 125,000 Daltons. These proteins assemble into fibers which are massive aggregates and do not have defined molecular weights.
