Development, validation and application of an UFLC-DAD-ESI-MS method for determination of carbonyl compounds in soybean oil during continuous heating.

A method was developed for the extraction and UFLC-DAD-ESI-MS analysis of carbonyl compounds (CCs) in oils heated to 180°C. Different parameters were evaluated, and the best results were 1.5ml of acetonitrile as the extraction solvent, manual stirring for 3min and 30min of sonication time.
