Webb13 juni 2024 · In the process of collagen gelatinization, breaking the non-covalent bonds and covalent cross-links in collagen is the key to promoting collagen gelatinization. In addition, high-quality gelatin should be a subunit component of collagen. WebbBased on viscosity structure relationship, it is pointed out that gelatinization of concentrated starch solutions is a two-step process consisting of initial swell-ing of the granule and its eventual disruption/dissolution (Kokini et al. 1992). The swelling is primarily a property of amylopectin, while amylose acts as a diluent.
