Gelatinization is an important physical phenomenon that occurs in starch-based foods during processing.It is a process that disrupts the native molecular orders of starch granules in the presence of water during thermal processing.During gelatinization process,granular swelling, loss of molecular orders,loss of birefringence and crystallinity, water uptake, marked increase in viscosity and the polysaccharides (amylose) solubiliza-tion occur.
