Known Application

  1. Can be used as a digestive aid. It is often used for indigestion caused by excessive consumption of protein foods, digestive dysfunction in the recovery period after illness, and pepsin deficiency caused by chronic atrophic gastritis, gastric cancer, and pernicious anemia.
  2. Enzyme preparations. It is mainly used in the production of fish meal and the hydrolysis of other proteins (such as soybean protein), the curdling effect in cheese production (combined with rennet), and can also be used to prevent the freezing and turbidity of beer.
  3. For biochemical research, protein structure analysis, and medicinally as digestive enzymes.
