  • A rapid, sensitive and simple chromogenic method was developed for quantitative determination of monosodium glutamate (MSG) in food samples. The method incorporated a glutamate oxidase and peroxidase. The librated H2O2 from a glutamate sample as a result of enzymatic action was measured using 4-aminoantipyrine and phenol as a chromogenic reagent at 502 nm. Glutamate calibration curve was linear up to 125 mmol L -1 with a detection limit of 2 mmol L -1 . The results of analyzing L-glutamate in… CONTINUE READING
