Abstract

Amaranth dye is an organic compound largely used in the food and beverage industries with potential toxicity effects on humans. In this paper, a new electrochemical sensor used for the determination of amaranth in foods was reported, where a kind of V2O5 nanoplates (V2O5-NPs) was employed as electrode modifying materials. The V2O5 nanoplates modified electrode enhanced its electrochemical signal obviously in the determination of amaranth in foods and exhibited a wider linear response ranging from 0.1-270.0 µM with a low detection limit of 0.04 ± 0.001 µM (3Sb/m). This work offers a new route in developing new electrochemical sensors for the determination of colorant additives and other hazardous components in foods.
