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. Webb26 juni 2024 · Gelatinization can be measured by observing the decrease of birefringence (the disappearance of the maltese cross). The first stage, the middle, and the last stages are the initial loss of birefringence (initiation). The range of temperatures at which total gelatinization occurs is established by the complete loss of birefringence.
