Phytase activity test according to DIN ISO 30024

Phytase provokes the enzymatic cleavage of phosphate from the phosphate storage substance phytate (the salt of phytic acid). The reaction also releases important minerals e.g. potassium, magnesium and iron bound to phytate.

Phytate is a secondary metabolite in plants storing phosphate and minerals in legumes and grain. During germination phytase is activated to make for growth important phosphate and minerals available.

Phytase occurs in microorganisms e.g. strains of lactobacillus. As symbionts in the abomasum of ruminants or in the intestine of some monogastric animals the microorganisms make phytate utilizable for the animals.

Phytase obtained from microorganisms is added to feed for pigs and poultry. Differently to the vegetable enzyme the microbial enzyme is acid-resistant and functions under the acidic conditions of the stomach. The usage of phytase causes a better utilisation of the feed by the animal and lowers the content of phosphate in the manure.

Phytase is also produced for biogas plants to cleave phytate in silage to provide phosphate, minerals and the carbon skeleton (inositol) to microorganisms.

We offer the measurement of phytase activity in biological samples and products. The analysis is performed in accordance to DIN ISO 30024.
