Product storage stability
According to the manufacturer, loss of activity will be less than 10% within one year if stored at room temperature.
Storage stability in premix and feed
No data
Heat stability
In one study, mash feed supplemented with the product was pelleted at 75, 80, 85 and 90°C. After pelleting, residual phytase activities were found to be 83, 97, 74, 58 and 67% of the initial phytase activity. Another study investigated the effect of pelleting at 65°C, 75°C, 85°C or 95°C. The corresponding residual activities of the product were 99, 78, 38 and 21%, respectively.
Homogeneity
No data
Carrier
Solid product: Wheat flour
Liquid product: Sorbitol, vegetable oil and sodium chloride
Handling
The European Commission states: "For safety: breathing protection, glasses and gloves shall be used during handling."
