High Activity Food Grade Pepsin Enzyme Powder
Product description
- Pepsin is a digestive protease secreted by gastric chief cells in the stomach. These cells secrete pepsinogen, which is then converted into pepsin when activated by gastric acid or existing pepsin. Pepsin is not produced directly by the cells.Its function is to break down dietary proteins into small peptide fragments. Some proteins are further decomposed into amino acids such as tyrosine and phenylalanine.Product Features:Pepsin is an endopeptidase with strong protein-digesting ability.It is mainly extracted from porcine gastric mucosa, and the product meets food-grade and pharmaceutical-grade standards.
Application of Pepsin
Pharmaceutical Industry
health products and medications to assist protein digestion, relieve indigestion, and improve nutrient absorption.
Food Industry
Applied in protein hydrolysis, cheese production, prepared meat products, and seafood processing to enhance flavor and texture.
Health & Nutritional Supplements
dietary supplements to support gastrointestinal function and promote efficient protein breakdown.

Conditions of Use
The optimal working pH for pepsint is 1.5–5.0. In neutral or alkaline solutions, pepsin will denature and lose its activity.
Recommended conditions for protein hydrolysis:dosage 5–15 U/g of dry protein,hydrolysis temperature 40–50 °C,hydrolysis time 2–4 hours,pH 2.0–2.5.
For pepsin tablets, the suggested activity is 100–300 U per tablet.For digestive enzyme products, the recommended enzyme activity is 50–100 U per serving.
Storage
Store in a cool, dry place away from light.
Recommended storage temperature: below 0 °C.
Enzyme activity may decrease to varying degrees if stored for an excessively long time or under unfavorable conditions. If temperature or humidity is too high, a proper increase in dosage is advised during application.
