• expensive. The spectrophotometric method suffers from poor selectivity due to interference from other compounds present in commercial fruit juices (e.g., sugars or glucuronic acid) while citrate may affect enzymatic methods [7]. Electrochemical techniques, particularly cyclic voltammetry (CV) and square
