Enzymes - Phytase

Phytases are a class of phosphatases, which catalyze the sequential hydrolysis of phytic acid to lower inositol phosphates and phosphoric acid. Phytic acid is an anti-nutrient present in plant-based feed and a poorly available source of phosphorus that comprises up to 80% of the total phosphorus in plants. Phytate acts as an anti-nutrient by forming complexes with proteins, carbohydrates and essential minerals and makes them unavailable. Phytate is heat stable and thus it withstands heat, harsh field conditions, and storage environments. Conventional food processing methods may decrease phytate to a degree but adversely affect the nutritional quality of the feed. In recent years, a number of investigations suggested the improvement of the nutritional quality of the feeds by supplementation with phytase. Monogastric animals lack adequate levels of phytate degrading enzyme in their digestive tract so they are unable to utilize the phosphorus of phytate.

Phytase frees the phosphorus contained in cereals and oilseeds, and by breaking down the phytate subsequently helps the release of other minerals such as calcium and magnesium, as well as proteins and amino acids, which are bound to the phytate. Thus, by releasing bound phosphorus in feed ingredients of vegetable origin, phytase makes more phosphorus available for bone growth, and reduces the amount excreted into the environment. Use of the enzyme also has the added benefit of helping to conserve natural resources by eliminating the need to supplement feeds with sources of digestible inorganic phosphorus. 
  • Reduce the total phosphorus content in livestock/poultry feeds, and reduce the excreted phosphorus through manure by 40-60%, thus reducing environmental pollution.
  • Increases the utilization efficiency of minerals, protein and other nutrients and improves the production performance of livestock/poultry.
  • Increases the space in feed formula to improve feed quality.
  • Reduces the risk of heavy metal poisoning and microbial pollution caused by Di calcium phosphate and bone meal, respectively.
