Nattokinase 5000 FU Powder – Food-Grade Active Enzyme Preparation – Fermented Nutritional Ingredient CAS 133876-92-3

Nattokinase 5000FU is a compliant, food-grade active enzyme ingredient produced via submerged liquid fermentation using Bacillus subtilis (natto strain). It is manufactured through a process involving cell separation, enzyme enrichment, low-temperature ultrafiltration purification, aseptic spray drying, and activity-stabilizing technology. Standardized to an activity level of 5000 FU/g, it meets national standards for cross-border food enzymes and dietary nutritional ingredients. The product appears as a light brownish-yellow fine powder that is dry, free-flowing, and free of clumps or pungent odors, retaining the mild, characteristic aroma of fermented natto. It exhibits excellent water solubility—dissolving clearly without sediment—and demonstrates high stability and tolerance to standard processing temperatures. Highly compatible with various formulations, it is rich in highly active nattokinase (a serine protease), natto polysaccharides, small-molecule peptides, and fermented amino acids. It has been processed to remove purines and Vitamin K1, making it ideal for use in dietary supplement formulations. Produced without organic solvent residues, pigments, preservatives, artificial adulterants, low-quality natto dregs, or sulfur fumigation; features high raw material purity. Ideal as an active enzyme ingredient for functional solid beverages, dietary tablets, wellness powder blends, and scientific research.Basic Product SpecificationsProduct Name: Nattokinase 5000FUEnglish Name: Nattokinase 5000FU (Food Grade)CAS No.: 133876-92-3Source: Liquid fermentation of Bacillus subtilis (soybean-based); refined via low-temperature processing to preserve enzyme activity.Product Grade: 5000 FU/g enzyme activity; food-grade enzyme preparation.Appearance: Fine, light brownish-yellow powder.Key Ingredients: Nattokinase active enzyme (5000 FU/g), natto peptides, fermented polysaccharides, small-molecule amino acids.Mesh Size: 80–100 mesh (fine texture; easy to dissolve and blend).Characteristics: Standardized 5000 FU activity; bio-fermented; Vitamin K1 and purine removed; excellent water solubility; stable enzyme activity; low hygroscopicity; batch-to-batch consistency.Applications: Functional dietary blends, solid beverages, nutritional tablets, wellness powders, DIY nutritional ingredients, scientific research, food enzyme additives.Compliance: Food-grade fermented enzyme ingredient; no additives or adulterants; compliant for cross-border trade.Storage & Shelf Life: Store in a sealed, cool, dry place away from light; 24-month shelf life.Scope of Application1.

It is intended solely for use as a food formulation additive, in nutritional blends, and for scientific research; it should not be consumed dry in large quantities or used as a substitute for medication. The powder is fine and dry, dissolving rapidly in both cold and hot water to form a clear solution without precipitation or residue. It offers excellent compatibility, blending well with nutritional powders, plant extracts, vitamins, and other dietary ingredients. Enzyme activity is preserved during both low-temperature and room-temperature processing, ensuring stability. Add the precise amount required by the formulation and mix thoroughly; it is compatible with standard processes such as powder blending, beverage formulation, and mass food production.Storage InstructionsStore in a sealed container within a cool, dry, well-ventilated, and clean environment, away from high temperatures, humidity, and direct sunlight. As a fermented enzyme powder designed to retain activity, it is prone to moisture absorption; high temperatures and strong light can rapidly degrade enzyme activity and reduce the effective FU value, while humid environments may cause clumping or the absorption of foreign odors. Do not store alongside materials with strong odors, strong acids, or high temperatures. Reseal immediately after opening to block air, moisture, and UV rays, thereby preserving the enzyme activity and powder quality, and ensuring consistency across batches.Important Notes1. This product is a food-grade fermented enzyme ingredient for dietary use; it is neither a finished food product nor a medication. It should not be consumed directly in large quantities and is intended only for compliant use in food formulations and scientific research.2. The powder is fine and has a mild fermentation odor; it is recommended to wear a mask and gloves during handling to prevent dust inhalation or direct skin contact. 3. Strictly adhere to food compliance standards; add according to the specified formula ratios. Usage beyond the permitted scope or dosage is prohibited.4. Individuals with impaired blood clotting, those taking medication, and pregnant or breastfeeding women should consult a healthcare professional before consuming products containing this ingredient.5. Store properly out of the reach of children and pets to prevent accidental ingestion.
