Accordingly, upon incubation at 55 C these hydroperoxides decompose into reactive species capable of oxidising the
‘‘fresh’’ lipids resulting in the formation of radicals, and explaining the increased tendency of radical formation, as seen in Fig. 3. Contrary to this, the increasingly oxidised CS sample (Fig. 1) obviously has less fresh lipids to feed the oxidation cycle, and thereby has less tendency to form radicals as reflected in the levelling observed in Fig. 3.
