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 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)

Q What is the origin of Pepsin and how is it produced?

Pepsin is a digestive protease naturally secreted by gastric chief cells in the stomach. These cells secrete pepsinogen, which is then activated by gastric acid or existing pepsin to convert into active pepsin. The commercial enzyme is mainly extracted from porcine gastric mucosa.

Q What is the optimal pH environment for Pepsin to maintain its activity?

Pepsin works best in highly acidic conditions. Its optimal working pH range is 1.5–5.0. It will denature and lose its activity when exposed to neutral or alkaline environments.

Q What are the recommended parameters for protein hydrolysis using Pepsin?

For optimal protein hydrolysis, it is recommended to use a dosage of 5–15 U/g of dry protein, a temperature maintained at 40–50 °C, a pH level of 2.0–2.5, and a hydrolysis duration of 2–4 hours.

Q How should Pepsin products be stored to prevent activity loss?

Pepsin must be stored in a cool, dry place protected from light, with a recommended storage temperature below 0 °C. Exposure to high temperature or high humidity may decrease enzyme activity over time.

Q What are the delivery and packaging options for different order sizes?

Small batches (1kg-25kgs) are packaged in aluminum foil bags inside a box and shipped via express door-to-door services like DHL, EMS, UPS, or Fedex. Larger orders (25kg or more) are packed in drums or cartons and can be shipped by Air or Sea.
