In food preparation, the function of amylase is the same as in the body. Amylase is produced primarily by the exocrine pancreas where the enzyme is synthesized by the acinar cells and then secreted into the intestinal tract by way of the pancreatic duct system. The main function of amylase is to catalyze the hydrolysis of starch into sugars. Saliva makes food moist, which helps chewing and swallowing and the digestion of food. Salivary Alpha-Amylase. The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Test.

These substances break down proteins, starches, fats and some sugars. This enzyme helps to break large starch molecules down into smaller sugar molecules. There are fewer causes for low amylase levels than for high amylase levels. Amylase is also produced in the small intestines and liver, both of which may contribute to normal serum amylase activity (Murtaugh and Jacobs, 1985; Nothan and Callow, 1971). There are two main types of amylase - salivary and pancreatic [1, 2]. When the temperature of an enzyme changes, so does the 3D structure of the enzyme. It can act only on cooked starch.
