ZnO/poly(nigrosine)/modified carbon paste electrode for selective sensing of vanillin in the presence of amaranth: a voltammetric study
In the current work, a ZnO/Poly Nigrosine (ZnO/PN MCPE) modifier was added to the unmodified carbon paste electrode to increase its sensitivity for analyzing vanillin (VAN) with the company of amaranth (AMR) using a cyclic voltammetric approach. In order to analyse ZnO nanoparticles, the X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy disperssive X-ray spectroscopy (EDS) studies was accomplished. The ZnO/PN MCPE succeeded in the development of electrochemical sensors for the detection of vanillin (VAN) by the ZnO/PN MCPE by cyclic voltammetry (CV) technique. Many different parameters was studied such as electrochemical investigation, scan rate, concentration, pH effect was studied. The simultaneous analysis of VAN in the presence of amaranth was studied. The detection limit and quantification limit was calculated and also oxidation of VAN was adsorption controlled. This profound method was successfully implemented for the investigation of vanillin in food samples. This modified electrode shows a very promising electrochemical sensing of VAN.
期刊介绍:
The Journal of Food Science and Technology (JFST) is the official publication of the Association of Food Scientists and Technologists of India (AFSTI). This monthly publishes peer-reviewed research papers and reviews in all branches of science, technology, packaging and engineering of foods and food products. Special emphasis is given to fundamental and applied research findings that have potential for enhancing product quality, extend shelf life of fresh and processed food products and improve process efficiency. Critical reviews on new perspectives in food handling and processing, innovative and emerging technologies and trends and future research in food products and food industry byproducts are also welcome. The journal also publishes book reviews relevant to all aspects of food science, technology and engineering.
