Webb17 mars 2024 · The product of this process is called a starch paste. Gelatinization is the process by which starches are heated and broken down by agitation into a gel. During gelatinization, the carbohydrate molecules in the starch granules absorb water, swell and separate from each other, forming a viscous gel. 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.
