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 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 and 58%, 67%, respectively, of the initial phytase activity. Another study investigated the effect of pelleting at 65°C, 75°C, 85°C or 95°C. The corresponding resdiual 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 Breathing protection, safety glasses and gloves shall be used during handling
Producer AB Vista
