Abstract

The quantitative production of malonaldehyde during the oxidation of pure, unsaturated fatty acids under controlled conditions, has been measured and correlated with their off-odor. It was found that malonaldehyde does not accumulate as a stable end-product of fat oxidation but reaches a peak at the same time that oxygen uptake begins declining. Oxidation products of all of the fatty acids investigated reacted slowly with TBA to give a compound absorbing at 450 m μ in addition to the malonaldehyde-TBA complex absorbing at 538 m μ. © 1960 American Oil Chemists' Society.
