Phytase is a general term for enzymes that catalyze the hydrolysis of phytic acid and its salts to inositol and phosphoric acid. Phytic acid, also known as inositol 6-phosphate, is the reservoir of phosphoric acid. The mineral elements are separated from the complex by phytase, increasing the nutritional value of the minerals. Phytase is widely used in food, feed, medicine, and other fields.
