A solid phytase composition having a phytase activity of above 20 FYT/g is prepared containing a lactic acid source such as corn steep liquor to stabilize the phytase. A starch source, disaccharide, filler, carrier, vitamins and/or minerals may be present in the composition. The composition can be prepared by spray drying or granulation. Granulates are preferred for using the composition to animal feed where the phytase eliminates the anti-nutritional effects of phytic acid.
