Food Processing and Brewing: Rapidly hydrolyzes proteins into peptides and amino acids under neutral or slightly acidic conditions, improving protein solubility, flavoring, and nutritional value in food and beverage systems.
Animal Feed Formulation: Added to livestock and poultry feed to break down anti-nutritional protein factors, enhancing protein digestibility and optimizing nutrient absorption for better animal growth performance.
Baking Industry: Modifies gluten protein structures in flour and dough systems, controlling dough elasticity, improving texture, and enhancing the overall quality of baked goods.
Leather and Textile Processing: Used in the bating and softening processes of leather making, gently removing non-collagenous proteins to enhance leather pliability and grain clarity under mild operational conditions.
Standard Packaging: Packaged in heavy-duty plastic drums, standard 25 kg/drum or 28 kg/drum. Customizable Packaging: Bulk packaging or tailored drum dimensions are available upon customer request. Shipping Precautions: Handle with care to prevent splashing and aerosol formation. Avoid transport under extreme heat or direct sunlight. The product is non-toxic and not classified as a hazardous cargo for sea, road, or air transport (Non-DG).
Temperature: Store in a cool, dark place, preferably maintained at 0–10 C for maximum shelf-life stability. Protection: Keep container tightly sealed. Avoid direct exposure to sunlight, rain, and moisture. Segregation: Keep away from strong acids, strong alkalis, and heavy metal ions (such as Hg2+, Pb2+, and Zn2+) which may trigger irreversible enzyme inactivation or inhibition.
