| Physical and Chemical Properties | This product is pepsin extracted from the gastric mucosa of pigs, sheep or cattle. It is a white or light yellow powder. Soluble in water, the aqueous solution is acidic. Isoelectric point pH = 1. Insoluble in ethanol, chloroform, ether. Non-toxic, with a special smell of meat; It is hygroscopic. Dry enzyme is relatively stable, heating to 1000C for 10min without inactivation. The aqueous solution starts to inactivate when heated to above 700C or above pH 6.2, and is irreversibly inactivated when pH>8. It is stable in strong acidic solution, and the optimum pH is 1.5~2. Its digestibility is strongest when it contains 0.2% ~ 0.4% hydrochloric acid (pH1.6 ~ 1.8), so it is often combined with dilute hydrochloric acid. Sugar-containing gastric protein enzyme preparation: this strain of pepsin is a white or light yellow powder diluted with lactose, glucose or sucrose; it is sweet, without mildew, and has a special smell of meat; it is insoluble in ethanol, ether, and chloroform; it is hygroscopic; the aqueous solution is acidic, and lg can digest 600g of solidified egg protein. |
| Use | Digestive medicine, used for the lack of pepsin or digestive dysfunction caused by indigestion |
