Abstract

This study reported on glutamate sensors based on chitosan as a heterogeneous membrane. The linearity was found to vary from 1.0 × 10-5 M to 1.0 × 10-1 M. The limit of detection was 5.0 × 10-6 M and the pH values were in the range from 4 to 6. The presence of ionic species normally found in foodstuffs did not interfere the electrode. The material for proposed electrodes were cheap and environmental friendly and therefore are suggested as alternative tools for the analysis of glutamate.
