Basic Info

Model No.: Nutrizyme PHY-P

Product Description


Nutrizyme®PHY-P (Phytase Premier I) [EC] is produced by submerged fermentation of Aspergillus niger followed by separation and formulation. The product is thermostable and resistant to pepsin and trypsin hydrolysis. It can break down the undigestible phytic acid (phytate) and release digestible phosphorus, calcium and other nutrients. As an animal Feed additive for poultry and swine feed, it can enhance the nutritive value by liberation of inorganic phosphate from phytic acid (myo-inositol hexakisphosphate) , thereby, reduce phosphorus pollution to the environment, and at the same time promote the absorption of metal ions.

1 unit of phytase equals to the amount of enzyme, which liberates 1 μmol of inorganic phosphorus in 1 min, from 5.0mmol/L sodium phytase at 37℃ and pH5.5

1. Enzyme properties at different pH conditions

feed-Nutrizyme PHY-P-1

Fig. 1.Relation between phytase activity and pH
The optimum pH of Sunson Phytase Premier I was 3.5 and the pH range was from 2.5 to 5.5. Compared to the current mainstream phytase in international market, Sunson phytase Premier I showed higher activity between pH2.5 to 5.5, which was more suitable for the digestion of phytic acid in animal gastrointestinal tract.
2. Temperature stability

(water bath for 3min under 75℃~95℃)
Fig. 2.Relation between phytase activity and temperature
The activity of Phytase Premier I could maintain 80% or more, which results showed the phytase had a very good heat resistance.
3. Stability under the feed pelleting process
An experiment was conducted in a feed factory in Shandong province. The phytase was fixed with the swine`s feed, conditioned for 90s at 85℃.0.4MPa and pelleted for 10s in a Modulator (AG,CH-9240, Bühler Co., Wuxi China), testing the thermostability during feed pelleting process.

Compared to the current mainstream phytase in international market, Sunson phytase Premier I has a better resistance to endogenous protease.
5. Phosphorus release capacity
The phytase was mixed with soybean meal, incubated at 40℃ for 4h at pH 3.0, then transferred to pH 6.5, 40℃ for 4h. Phosphorus release was determined as below.

Fig. 5 Phosphorus release capacity
Results showed Phytase Premier I had much higher phosphorus release capacity than the mainstream phytase.

1. Effectively hydrolyze phytate in plant materials, improve phosphorus utilization of feed raw material;

2. Reduce the dosage of inorganic phosphorus and save cost of animal feed.

3. Break phytanate frame, release nutrients, like: starch, protein, mineral elements, increase the utilization rate;

4. Improve phosphorus absorption and reduce environmental pollution.

1. Produced through advanced liquid fermentation and extraction technology;
2. Good resistance to endogenic protease and gastric acid;
3. Thermostable, wide pH range, catalyzing effectively in animal gastrointestinal tract.
4. Even granular, appropriate grain size, blend equally;
5. Highly concentrated and cost saving.

1. Packaging specification: 25 KGS/Bag.
2. The shelf life is 12 months under 20℃.
3. Damp and insolation should be avoided. Store it in a cool, dry and ventilated place.

Note:The Mainstream phytase means the current mainstream phytase in international market.
