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.

Storage STORED HUMIDITY PROTECTED (RH LESS THAN 60) AT TEMPERATURE BELOW 25℃
Shelf Life 1 Year when Properly Stored

Conditions of Use

⚗️ Optimal working pH for pepsin: 1.5–5.0. In neutral or alkaline solutions, pepsin will denature and lose its activity.
  • Recommended dosage for protein hydrolysis: 5–15 U/g of dry protein
  • Hydrolysis temperature: 40–50 °C
  • Hydrolysis time: 2–4 hours
  • Optimal pH range: 2.0–2.5
  • For pepsin tablets, suggested activity: 100–300 U per tablet
  • For digestive enzyme products, recommended enzyme activity: 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)

Q What is pepsin and where does it come from?
Pepsin is a digestive protease secreted by gastric chief cells in the stomach. It is activated from pepsinogen by gastric acid or existing pepsin. Commercially, it is primarily extracted from porcine gastric mucosa and is available in both food-grade and pharmaceutical-grade forms.
Q What is the optimal pH range for pepsin activity?
The optimal working pH for pepsin is 1.5–5.0. Outside this range — particularly in neutral or alkaline solutions — pepsin will denature and lose its enzymatic activity. For protein hydrolysis applications, a pH of 2.0–2.5 is recommended.
Q What are the main applications of pepsin?
Pepsin is widely used across multiple industries: in the pharmaceutical industry for digestive health products; in the food industry for protein hydrolysis, cheese production, and meat/seafood processing; and in health & nutritional supplements to support gastrointestinal function and efficient protein breakdown.
Q How should pepsin be stored to maintain its activity?
Pepsin should be stored in a cool, dry place away from light, at a recommended temperature below 0 °C. Storage humidity should be kept below 60% RH. Prolonged storage or unfavorable conditions may reduce enzyme activity; in such cases, a slight increase in dosage is advised.
Q What dosage of pepsin is recommended for protein hydrolysis?
For protein hydrolysis, the recommended dosage is 5–15 U/g of dry protein, at a temperature of 40–50 °C, for a hydrolysis time of 2–4 hours at pH 2.0–2.5. For pepsin tablets, the suggested activity is 100–300 U per tablet; for digestive enzyme products, 50–100 U per serving is recommended.
Q What packaging options and shipping methods are available?
Pepsin is available in 1 kg bags (double plastic bag + aluminum foil bag, boxed) and in 10 kg, 25 kg or larger quantities packed in drums or cartons with inner plastic bags. Shipping options include EMS, DHL, UPS, FedEx for small orders (1–25 kg), and air or sea freight for larger shipments. Delivery times range from 3–7 days (air) to 10–35 days (sea freight).
