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

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 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 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
QWhat is pepsin and where does it come from?
APepsin is a digestive protease secreted by gastric chief cells in the stomach. It originates from pepsinogen, which is activated by gastric acid or existing pepsin. Commercially, it is mainly extracted from porcine gastric mucosa and is available in food-grade and pharmaceutical-grade standards.
QWhat is the optimal pH range for pepsin activity?
APepsin works best at a pH of 1.5–5.0. In neutral or alkaline environments, pepsin will denature and permanently lose its enzymatic activity. For protein hydrolysis applications, a pH of 2.0–2.5 is recommended.
QWhat industries use pepsin and for what purposes?
APepsin is widely used across three major industries: the pharmaceutical industry (digestive medications and health products), the food industry (protein hydrolysis, cheese production, meat and seafood processing), and the health supplement industry (gastrointestinal support and protein breakdown).
QWhat are the recommended conditions for protein hydrolysis using pepsin?
AFor optimal protein hydrolysis, use a dosage of 5–15 U/g of dry protein, maintain a temperature of 40–50 °C, allow a hydrolysis time of 2–4 hours, and keep the pH between 2.0–2.5.
QHow should pepsin be stored to maintain its activity?
APepsin should be stored in a cool, dry place away from light, ideally at a temperature below 0 °C. Excessive heat or humidity can reduce enzyme activity over time. If stored under suboptimal conditions, increasing the dosage during application is advised.
QWhat packaging and shipping options are available?
AFor small orders (1kg), pepsin is packed in an aluminum foil bag with double plastic inner bags inside a box. For larger quantities (10kg, 25kg+), drums or cartons with double plastic liners are used. Shipping is available via EMS, DHL, UPS, FedEx, air freight, or sea freight, with delivery times ranging from 3–7 days (express/air) to 10–35 days (sea).
