Abstract
The present invention relates to solid enzyme, in particular phytase, compositions stabilized with a lactic acid source such as Corn Steep Liquor (CSL), and methods of producing the same. Preferred compositions additionally comprise starch and disaccharides such as lactose or trehalose.
Claims33
A solid phytase composition comprising:
- (a) an enzyme having phytase activity, and
- (b) a lactic acid source,
- wherein the phytase activity of the composition is above 20 units/g.
A process for preparing a solid phytase composition which comprises drying a lactic acid source together with an enzyme having phytase activity, wherein the phytase activity of the solid composition is above 20 units/g.
A solid phytase composition consisting essentially of:
- (a) an enzyme having a phytase activity of above 20 FYT/g of the composition, and
- (b) a lactic acid source in an amount of 0.01-15% by weight to provide lactic acid in an amount sufficient to stabilize the enzyme.
