Synthetic antioxidants most used in oil-based food to avoid oxidation processes, butylated hydroxyanisole (BHA), butylated hydroxytolueno (BHT), and dodecyl gallate (DG), were analyzed in edible oils using micellar electrokinetic capillary chromatography (MECK) with bis-(2-ethylhexyl) sodium sulfosuccinate as the pseudostationary phase.Studies involving solid-phase and liquid–liquid extraction were...
Capillary electrokinetic chromatography is suitable for the separation of mixtures of uncharged and charged solutes. In the present work the behavior of six synthetic food antioxidants – 2[3]-tert.-butyl-4-hydroxyanisole, 2,6-di-tert.-butyl-p-cresol, tercbutylhydroquinone, 3,4,5-trihydroxybenzoic acid propyl ester, 3,4,5-trihydroxybenzoic acid octyl ester and 3,4,5-trihydroxybenzoic acid dodecyl ester...
