Abstract

Carmoisine (azorubine, E 122) is a synthetic food azo dye used to colour sweets, beverages, and medicines. In our previous work, we highlighted the process of electrochemical reduction of the dye on a stationary silver solid amalgam electrode (AgSAE) [1]. We have carried on our research and optimised the instrumental parameters for the determination of carmoisine using differential pulse voltammetry (DPV).
