Abstract
The objective of this study was to develop antioxidant compound analysis technique by using electroanalysis approach. Five different samples from five monofloral honey were used in this work. The electroanalysis experiments were conducted using two different techniques, namely cyclic voltammetry (CV) performed with scan rate of 50 mV/s and different pulse voltammetry (DPV) with pulse amplitude 50 mV and scan rate 10 mV/s. All of the samples were also analysed by spectroscopy techniques, namely Ferric Reducing Ability of Plasma (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH). The electrochemical index determined using DPV uyiiuiouiitechnique agreed with the spectrometric FRAP and DPPH measurements. This result shows that the electroanalysis method could be potentially utilized for antioxidant analysis of honey samples.
