Phytase

الوصف

 Phytase is a kind of enzymes which can catalyze phytic acid and its phytates hydrolyzing into inositol and phosphate, it belongs to phosphoric monoester hydrolases. Phytase can decompose natural organophosphorus in the animal feed, promotes the utilization of some nutrient substances, like starch, protein, amino acid, microelements and so on. It replaces part of calcium hydrophosphate in feed, which can reduce the cost of feed effectively. Definition of enzyme activity:       As GB/T *********9, one phytase activity unit (U) is defined as the amount of enzyme which liberates 1µmol inorganic phosphorus from 5.0 mmol/L sodium phytate solution per minute at *7℃ and pH 5.5. Functions:

1. Hydrolyze Inositol phosphate ester bond of phytate phosphorus, decompose the phytic acid and phytate into inositol and phosphate, improve the utilization of phytate phosphorus in feedstuff.
2. Destroy the chelate structure of phytate, the nutrient substances chelated are released, like mineral elements, protein, starch and so on, which improves the feed utilization.
3. Hydrolyze phytic acid, reduce the inhibition to physiological active substances in the digestive tract in order to improve the production performance of animals.
4. Phytase increases the security of feed as green feed additive, reduce the discharge and environment pollution of phosphorus.
