Determination of total aldehydes in fatty acid oxidation products was accomplished by using a colorimetric procedure based on 2,4‐dinitrophenyl‐hydrazine derivatives. To overcome problems of high reagent blanks and poor reproducibility the carbonyl derivatives were separated from excess reagent by extraction. Solubility and phase interface problems were avoided by using a sample dispersing solvent. Potential interferences were explored. The final procedure was demonstrated to be applicable from 25 µmoles to 2 mmoles/g carbonyl with a relative standard deviation of 3.5%.
