The process of gelatinization

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. WebbStarch Gelatinization. Starch gelatinization is an endothermic process that corresponds to the loss of starch crystallinity in the starch granules under particular heat and moisture …
