WebIn this article, we report the kinetics and influence of unreduced phytic acid on phosphate estimation by three of the often-used methods for phytase estimation, the AOAC, Cooper-Gowing, and Fiske-Subbarow methods. Our results show that the AOAC method is most suitable to estimate the phytase activity in the presence of phytate in the medium.
