✦ Synopsis

A simple and rapid flow-injection analysis (FIA) of phytic acid in cereal food samples is reported based on a modified molybdenum blue method. The interference from inorganic phosphate ion was eliminated by using an anion exchange resin. The samples treated with the ion exchangers were analysed using an FIA system at a sampling rate of 60 samples per hour, and the determination showed a working range from 0.05 to 2.0 Γ‚ 10 Γ€3 M of phytic acid. The method was highly reproducible for measuring phytate in food material and proved to be more rapid than conventional methods.

2-p-Toluidinylnaphthalene-6-sulfonate (2,6-TNS) is a compound which is barely fluorescent in pure water but whose fluorescence can be strongly enhanced if the environment becomes hydrophobic, i.e. by the addition of suitable substrates such as proteins or 1,4-␣-Dglucans. The enhancement of fluoresce
