Six edible oils with different fatty acid compositions were used to explore nonpolar lipophilic aldehydes/ketones produced by possible parent fatty acids after accelerated oxidation. Simultaneous determination of 20 aldehydes and five ketones within the C2-C10 range was carried out using

The most widely used method for qualitative and quantitative analysis of carbonyl compounds is the 2,4-dinitrophenylhydrazine method through the formation of 2,4-dinitrophenylhydrazone derivatives. However, this method may cause an analytical error because 2,4-dinitrophenylhydrazones have both E- and Z-stereoisomers. Purified aldehyde-2,4-dinitrophenylhydrazone
