WebIn the Fiske-Subbarow colorimetric method for the determination of phosphate, the color yield is directly proportional to the amount of inorganic phosphate only when the aliquot taken for analysis contains between 0.1 and 1.0 µmole of phosphate. The efficiency of the enzymatic formation of glucose-1-phosphate will vary somewhat Webthis method differs from that of the Fiske-Subbarow and Allen methods. That is, Allen's method was stable during the time interval of 5 minutes to 30 minutes but the Gomori method became stable after a time lapse of 30 minutes. (At room temperature, no change is_ observed between the time interval of 30 minutes to 120 minutes.) This means that ...

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.
