Criteria for selecting a Fast Phytase

Lode Nollet, Global Product Manager Enzymes, Huvepharma What are the criteria to select a good phytase? Why select the fastest phytase? The importance of pH profile, pepsin resistance and speed (PPS) has shown to be critical to yield a fast phytase with reliable matrix values and superdosing properties.  The main reason for using an exogenous added  phytase in feed is to liberate phosphorous (P), bound as phytate, in raw materials. This does not  only lead to a lower feed cost by reducing the amount of added inorganic P, but also…
