Product Description

Product Description

pepsin 1
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 pepsin 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.

Frequently Asked Questions (FAQ)

What is pepsin and where does it come from?
Pepsin is a digestive protease naturally secreted by gastric chief cells in the stomach. Commercially, it is mainly extracted from porcine (pig) gastric mucosa and is available in both food-grade and pharmaceutical-grade standards.
What is the optimal pH range for pepsin activity?
The optimal working pH for pepsin is 1.5–5.0. In neutral or alkaline solutions (pH above 5.0), pepsin will denature and rapidly lose its enzymatic activity. For protein hydrolysis, a pH of 2.0–2.5 is recommended.
What are the main applications of pepsin?
Pepsin is widely used in the pharmaceutical industry (digestive medications), the food industry (protein hydrolysis, cheese production, meat and seafood processing), and in health & nutritional supplement products to support gastrointestinal function and protein breakdown.
How should pepsin be stored to maintain its activity?
Pepsin should be stored in a cool, dry place away from light, at a temperature below 0 °C. Excessive storage time or unfavorable conditions (high temperature or humidity) may reduce enzyme activity. In such cases, a slight increase in dosage is advised during application.
What are the recommended dosage conditions for protein hydrolysis using pepsin?
The recommended conditions are: dosage of 5–15 U/g of dry protein, hydrolysis temperature of 40–50 °C, hydrolysis time of 2–4 hours, and pH of 2.0–2.5. For pepsin tablets, the suggested activity is 100–300 U per tablet.
What packaging and shipping options are available?
Pepsin is available in 1kg bags (double plastic bag + aluminum foil inner bag) or in drums/cartons for 10kg, 25kg, or larger quantities. Shipping options include EMS, DHL, UPS, FedEx (1–25kg, 3–7 days door-to-door), air freight, and sea freight (10–35 days) for orders over 100kg.
