thermostable phytase feed enzyme

Detail Information

Definition of Unit

1 unit(U) of phytase equals to the amount of enzyme, which releases 1?mol of inorganic phosphorus from 5.0 mmol/L sodium phytate solution in 1 min at 37℃ and pH 5.5 .


1. Degrade phytate, release more organic phosphorus.

2. High dosage improves utilization of mineral(Ca2+Fe3+Zn2+Mn2+Na+K+), amino acid, energy etc.

3. Save inorganic phosphorus.

4. Suitable for practical pelleting temperature 80~90℃.

1. High temperature tolerance

2. Wide pH range

3. Non-coated for commercial product

4. Good flowability for easy mixture

Disadvantages of coated phytase

1. Decrease the surface between enzyme and substrate

2. Wax-like substance coat inhibit the release of enzyme, but the determined activity is high

3. Coated materials cost is high

4. Beads must be produced before coat

5. Poor release effect in gastrointestinal tract


Specification 5,000 U/g
Recommend Dosage 60~100g/MT Complete Feed
