The spectrophotometric method for estimation of P based on molybdovanadophosphoric acid complex was improved for sensitivity (8-10 fold) by decreasing reagent concn. to one-third and measuring absorbance as its lambda max (355 nm). Range of the method was 0.5-7 mug/ml for 1 cm light path. P content of potato starch remained unchanged upon acid modification or oxidation with hypochlorite. Maize and tapioca starch, on the other hand, lost about 30-40% P upon acid modification. The difference is attributed to state of P in the respective starch granules.
