    First, saliva amylase in the mouth hydrolyzes starch into dextrin and maltose. Secondly, pancreatic amylase and disaccharide enzymes secreted by the pancreas in the small intestine continue to decompose dextrin and maltose into monosaccharides for absorption by intestinal mucosal cells. Starch will swell gradually when heated to above 60℃, and finally become a paste. This process is called "gelatinization". The digestive enzymes of the human body are relatively easy to hydrolyze the gelatinized starch molecular structure. However, after the gelatinized starch is cooled, the molecules in the starch are rearranged and the water is discharged, resulting in a "sizing" phenomenon, which is called "aging" of the starch.
