Description
FERMENTATION INGREDIENT
Bacillus subtilis natto (fermentation) — 20000 FU/g
纳豆激酶 is a fermentation-derived enzyme preparation, quoted on activity units rather than on a percentage, because activity is what the application depends on.

Buyer Decision Guide
Confirm the activity unit definition. FU values are not comparable unless the assay method is the same.
- Assay / grade: 20000 FU/g, tested by Fibrinolytic activity assay (FU).
- Identity: Bacillus subtilis natto (fermentation), Fermentation broth.
- Appearance: white to off-white powder.
- Water-soluble; activity drops quickly in dilute solution, so dose close to filling.
- Packing and storage: sealed food-grade liner in an export carton or fibre drum; keep cool and dry.
- Documentation: COA, specification sheet and SDS issued with each batch.
How This Grade Differs
No grade of this product was listed on the site before this page, so it introduces the product directly. Confirm the grade in the written quotation before the first order.
Quality and Documentation
Released on a batch certificate covering assay or grade, identity, moisture, heavy metals and microbiology.
Frequently Asked Questions
How long can we hold stock before use?
Two years from the manufacture date when the pack stays sealed and dry.
Which safety parameters are tested every lot?
Moisture per specification, ash per specification, heavy metals and microbiology against the approved specification.
Which molecular weight profile applies?
The declared specification is 20000 FU/g, and the peptide distribution is reported with the batch.
Which batch is the quotation based on?
A representative batch is named on the quotation; the lot you receive is released on its own certificate.
How is appearance checked?
White to off-white powder, compared against a retained sample from the approved batch.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
