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
⚠️ The optimal working pH for pepsin is 1.5–5.0. In neutral or alkaline solutions, pepsin will denature and lose its activity.
  • Recommended dosage: 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 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)
What is pepsin and where does it come from?
Pepsin is a digestive protease secreted by gastric chief cells in the stomach. It is primarily extracted from porcine 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 environments, pepsin will denature and lose its enzymatic activity.
What are the main applications of pepsin?
Pepsin is widely used in the pharmaceutical industry for digestive health products, in the food industry for protein hydrolysis and cheese production, and in nutritional supplements to support gastrointestinal function.
How should pepsin be stored to maintain its activity?
Pepsin should be stored in a cool, dry place away from direct light, ideally below 0 °C. High temperature or humidity may reduce enzyme activity over time, and an increased dosage may be needed under such conditions.
What are the recommended conditions for protein hydrolysis using pepsin?
The recommended conditions are: dosage of 5–15 U/g dry protein, hydrolysis temperature of 40–50 °C, hydrolysis time of 2–4 hours, and pH of 2.0–2.5 for optimal results.
What shipping methods are available and how long does delivery take?
For small orders (1–25 kg), express couriers such as DHL, UPS, FedEx, and EMS are available with a 3–7 day delivery time. Larger orders over 100 kg can be shipped by air (3–7 days) or by sea (10–35 days) depending on the destination.
