PRODUCT DESCRIPTION
Feed grade acid protease enzymes for animal nutrition additive
INTRODUCTION
Nutrizyme® PRA is an acid protease preparation and Nutrizyme® PRN is a neutral protease produced by submerged fermentation of Aspergillus niger and Bacillus subtilis, respectively, followed by purification and formulation.
Protease catalyzes the cleavage of peptide bonds in a polypeptide (protein) chain, producing smaller molecular peptides and amino acid. The cleavage improves protein’s dispersibility, solubility, palatability and digestibility, and therefore helps animal with the digestion and absorption of nutrients in feed and better utilization of feed.
DEFINITION OF UNIT
1 unit of Acid Protease equals to the amount of enzyme, which hydrolyzes casein to get 1 μg of tyrosine in 1 min, at 40℃ and pH 3.0.

*Color can vary from batch to batch. Color intensity is not an indication of enzyme activity. **1 unit of Acid Protease equals to the amount of enzyme, which hydrolyzes casein to get 1 μg of tyrosine in 1 min, at 40℃ and pH 3.0.
DOSAGE
Acid protease: 10-25G/MT of completed feed; or add according to the formulation.
FUNCTIONS & BENEFITS
* Hydrolyze the proteins in feed effectively, improving protein digestion of animals and biological value of feed. * Complement endogenous digestive enzymes, reduce the risk of diarrhea, and promote animal growth performance.
PACKAGE&STORAGE
* Package：25kg/bag * Storage： Keep sealed in a dry and cool place and avoid direct sunlight. * Shelf life: 12 months in a dry and cool place (20℃).
SAFE HANDLING PRECAUTIONS
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided.If irritation or allergic response for skin or eyes develops, please consult a doctor.
