Electro-chemical system for the determination of degree of unsaturation of edible oils

The research paper describes platinum–calomel electrodes electro-chemical system for the determination of degree of unsaturation of edible oils. The change in potential, when platinum and calomel electrodes are immersed in 2% iodine mono-chloride solution (ICl) in acetic acid with respect to iodine mono-chloride solution containing edible oil, has direct correlation to degree of unsaturation of edible oils. Edible oils have a chain of carbon atoms with double bonds where addition of halogen reagent takes place. In this investigation iodine mono-chloride solution in glacial acetic acid reacts with edible oils and change in potential of reaction mixture with respect to ICl stock solution using platinum and calomel electrodes relates to the degree of unsaturation of edible oils. A portable system has also been fabricated in which potential change directly relates to iodine number of the edible oils, which is directly displaced on Liquid Crystal Display (LCD).
