Fatty acid composition had a major effect on the rise of peroxide value in the oxidation chamber, oils rich in monounsaturated fatty acids are usually more stable to auto-oxidation, and therefore, CO yielded the lowest peroxide value as compared to SBO and SFO.

Auto-oxidation of unsaturated fatty acids is a complex self-catalyzing free radical chain reaction (Porter et al.
(2) Several mechanisms seem to be involved in the generation of OS in the presence of elevated glucose concentrations; they include glucose auto-oxidation, enhanced glucose flux through the polyol pathway, and non-enzymatic and progressive glycation of proteins with consequent increased formation of glucose-derived advanced glycosylation end products (AGEs).

During the processing or compounding, the rubber is exposed to higher heat and shear, with oxygen present, and the stabilizer helps to maintain the needed properties of the rubber by preventing degradation upon production and auto-oxidation during storage, i.e., providing excellent shelf life.
