【Named As】: myo - inositol hexakisphosphate phosphohydrolase
A phytase is any type of phosphatase enzyme that catalyzes the
hydrolysis of phytic acid (myo-inositol hexakisphosphate) – an
indigestible, organic form of phosphorus that is found in grains
and oil seeds – and releases a usable form of inorganic phosphorus.
Research in the field of animal nutrition has put forth the idea of
supplementing feed with phytase so as to make available to the
animal phytate-bound nutrients like calcium, phosphorus, other
minerals, carbohydrates, and proteins, and reducing its
Our extensive range of phytases delivers great increases in
phosphorus release, improving performance and cutting costs.
Phosphorus is an essential nutrient in livestock diets. It affects
growth, reproduction and feed use. Much of the naturally occurring
phosphorus in feed ingredients is unavailable to animals. With most
plant phosphorus being excreted undigested, inorganic phosphate has
to be added to diets to compensate. Increasing phytic acid
degradation and the availability of plant phosphorus can have major
benefits for poultry and swine producers, including:
- Lower levels of inorganic phosphorus in diets
- Reduced feed costs
- Better sustainability of animal production
This product was produced by Aspergillus niger strain, which
fermented in submerged medium.
The optimal pH of the phytase was about pH=4.5—5.5. It still keeps
high activity at the range of pH=4.0—8.0. The optimal temperature
of the phytase was about 45℃—55℃. It still keeps high activity at
the temperature range of 20℃—75℃.
- Ability to survive in a wide range of pH value；
- Better resistance to endogenous enzymes in the animals digestive
- Better resistance to the trace element in the feed;
- Higher purity and stability;
- Better thermal stability,Ultrafine granule to provide excellent
flowability to improve mixing uniformity in feed

【DEFINITION OF PHYTASE ACTITIY】
One phytase unit (U) is defined as the amount of enzyme which
liberates 1μmol inorganic phosphorus per minute from 5.0mmol/L
sodium phytate at 37℃, pH5.5.
【PACKAGE AND STORAGE】
Package: 25 kg/bag or 25 kg/drum for solid product.
Storage: Keep away from heat, moisture, and direct sunlight.
Shelf life: 12 months for solid products when stored in room
temperature ( <25 oC) and dry place.
The phytase products could be mixed with the feed before or after
the granulation step in the process of feeds production.
