In this study, thin layer chromatography (TLC) coupled with visible (Vis) spectrophotometry was established as a simple method of determining diacylglycerols (DGs). Samples were analyzed on TLC plates, developed, and then eluted to prepare the test solution. This solution was scanned on an ultraviolet spectrophotometer to ensure that the maximum absorbance of DGs was at 700 nm. Afterward, the relationship...
In this study, a new method for determining peroxide value (PV) of edible oils was described. The basis of this method was the determination of changes in the electrical conductivity (EC) values of the aqueous phase during the reaction of potassium iodide (KI) with the hydroperoxides presented in oil samples. The effect of various analytical conditions was evaluated, such as temperature, holding time,...
