Cottonseed oil containing 0, 2.5, 5 and 10% added moisture was heated to simulate food‐frying conditions. The volatile carbonyls from the heated oil were crystallized as 2,4‐dinitrophenylhydrazones and then regenerated for separation by gas‐liquid chromatography. Nineteen peaks were observed for the dry oil; oil with added moisture had fewer peaks. Oil containing added moisture produced more total carbonyl by weight than did dry oil. Maximum production of carbonyls occurred in the oil with 2.5% added moisture.
