 note = {In the previous report, it was confirmed that most of volatile carbonyl compounds
found in fish flesh during storage was produced by the atmospheric oxidation of lipid
fraction in the flesh. Studies on the autoxidation of fatty materials have revealed the
facts that the primary products of autoxidation are the peroxide or hydroperoxide (PV),
and that by the transformation or decomposition of the peroxide and the interaction of
the peroxide with other materials of autoxidation and further oxidation of the peroxide,
the secondary products may be formed, including various aldehydes, ketons and acids
etc., some of which are responsible for rancid flavour and ordor. However, there has
been probably little experimental evidence about the mechanism by which the lower
products are formed.
And then, in order to obtain some information on the process of the formation of
lower carbonyl compounds by the oxidation, a preliminary experiment was carried out in
considering the relationship between the formation of water-soluble carbonyl compounds
(SC) and the quantity of the peroxide and between the formation of water-soluble
and non-water-soluble carbonyl compounds (NC), adopting the oxidative action of
soybean lipoxidase for linoleic acid., The formation of SC by the enzymatic oxidation of linoleic acid could hardly be
perceived under the presence of smaller quantity of PV, while that of TC was appreciable
in the same case. The addition of NC fraction to the mixture resulted in the acceleration
of SC-formation and the inhibition of PV-formation. By some variations of the substrate
concentration, the rate of PV-formation was considerably affected, while that of SC
was hardly affected. Thus, SC produced by the oxidation of linoleic acid, was supposed
to be a later product derived from NC consequent on the formation of PV.},
