Product Description

Product description

Serrapeptidase is an independently developed enzyme product, produced through fermentation, extraction and purification from Serratia bacteria. Also known as Serratia protease, it is an alkaline proteolytic enzyme with excellent anti-inflammatory and anti-edema effects.

In recent years, market demand for serrapeptidase has been strong as an adjuvant pharmaceutical and health food ingredient.

Product Features

Produced by liquid fermentation with nanobiotechnology, enabling precise extraction of active ingredients. The product’s kinase activity reaches above 2200 SPu/mg.
Compared with other pharmaceuticals, serrapeptidase offers the advantages of low cost, high safety, small molecular weight, good oral absorption and excellent anti-inflammatory effect.
Suitable reaction temperature: 30–45°C, optimal at 37°C; denatures and inactivates above 80°C. Suitable reaction pH: 6–9, optimal at pH 7.2; inactivates below pH 5.

Storage

Keep in a cool, dry and dark place. Storage temperature: below 0°C.

Prolonged or improper storage may reduce enzyme activity. If exposed to high temperature or humidity, an appropriate increase in dosage is recommended.

Enzyme inactivation depends on conditions including substrate concentration, pH and temperature. It will be inactivated after 15 minutes at above 80°C or below pH5.

Frequently Asked Questions (FAQ)

What is the source of your Serrapeptase enzyme?

Our Serrapeptase is produced through high-density liquid fermentation, extraction, and purification using non-GMO Serratia bacteria, followed by a freeze-drying process to ensure maximum enzyme viability.

What is the standard enzyme activity for this product?

The product is designed to meet high potency standards. The standard kinase activity reaches above 2,200 SPu/mg, with typical batch testing results yielding up to 2,480 SPUnits/mg.

How should the Serrapeptase freeze-dried powder be stored?

It must be kept in a cool, dry, and dark place. For optimal preservation of enzyme activity, storage below 0°C is highly recommended. Ensure it is protected from humidity (relative humidity less than 60%).

At what temperature and pH does the enzyme become inactive?

Serrapeptase denatures and becomes inactive when exposed to temperatures above 80°C or acidic environments below pH 5 for more than 15 minutes. The optimal operating temperature is 37°C and the optimal pH is 7.2.

What are the primary fields of application for Serrapeptase?

Serrapeptase is widely utilized in the pharmaceutical industry for anti-inflammatory and swelling-reduction products, in dietary supplements for joint care and sports recovery, in biomedical research for protein hydrolysis, and in functional cosmetics.

What packaging options are available for wholesale orders?

For smaller quantities, we provide 1kg aluminum foil bags with double plastic lining inside. For bulk orders, we offer secure packaging in 10kg or 25kg drums or cartons.
