Neutral protease
This neutral protease is a Bacillus subtilis fermentation-derived enzyme preparation supplied as a solid powder. It achieves an enzyme activity of 50000 u/g under the defined condition of 30°C and pH 7.5, where 1 g of the powder hydrolyzes casein to produce 1 µg of tyrosine per minute. The product contains less than 6% moisture and is packaged in 2 kg inner bags with 20 or 30 kg outer packaging, conforming to the Chinese business standard QB1805-93 for industrial enzyme preparations.
The enzyme is effective across a pH range of 6.5 to 7.5 and a temperature range of 35 to 45°C, making it suitable for applications requiring controlled protein hydrolysis. It is used in food processing, animal feed, pharmaceuticals, and textiles for functions such as fur removal, skin softening, silk degumming, film reclamation, and medical treatments for chronic bronchitis. In animal feed, it is often combined with amylase, acid protease, cellulose, and other enzymes to improve nutrient digestibility.
Buyers typically include manufacturers in the food, textile, and pharmaceutical industries, as well as feed producers for livestock and aquaculture. The product is traded under HS code 3507.90 for customs clearance and requires storage in cool, dry conditions away from direct sunlight and heat. Enzyme activity remains above 85% after six months when stored at 25°C, ensuring stability for global export.

Sourcing Neutral protease from Anke Bioengineering Co., Ltd. - China Import Guide
Before ordering, verify the enzyme activity level and confirm it aligns with your application requirements, as activity can vary between batches. Request a certificate of analysis to ensure the product meets the specified 50000 u/g activity and moisture content below 6%. Check that the packaging is intact and suitable for your intended use, particularly if you require specific inner or outer packaging configurations.
Confirm logistics details such as lead time, shipping Incoterms (e.g., FOB or CIF), and payment terms. For international shipments, ensure the supplier can provide the necessary export documentation, including the HS code 3507.90 for customs clearance. Discuss temperature-controlled shipping options if your climate or transit conditions risk exposing the enzyme to heat or moisture.
Conduct quality checks upon receipt by testing enzyme activity under your operational conditions (30°C, pH 7.5) to verify it meets the stated 50000 u/g. Inspect the product for moisture content and packaging integrity. Request documentation such as the QB1805-93 compliance certificate and storage stability data to confirm the enzyme’s suitability for your specific application.
