Activity definition

One unit of phytase activity is defined as the amount which liberates one mole of inorganic phosphorus per minute from 5 micromol/L of sodium phytate at 37 degree C and pH 5.5.

Activity test method

The analytical method is based on the liberation of inorganic phosphorus from sodium phytate. Incubation is carried out at pH5.5 and 37 degree C for 30-60 minutes. The liberated phosphorus is analyzed by the molybdenum blue method and quantitated by photometry at 415nm.

A phytase standard of known activity is treated in the same way. The measured increase in absorption of the product sample is compared with that for the standard (relative method)

Recommended Use level

80-100g/ton feed.

12 months under cool, dry, low temperature storage condition.
