lycerols, phospholipids, lipoproteins, and an autoxidative process or in conjunction cholesterol constitute the main lipid com- with fatty acid oxidation (Hotchkiss and pounds in meat that are susceptible to oxida- Parker 1990). Cholesterol oxides are consid- tion. Phospholipids are very susceptible to ered to be prejudicial for health due to their oxidation due to their high content in poly- role in arteriosclerotic plaque but can also be unsaturated fatty acids. Oxidation may be mutagenic, carcinogenic, and cytotoxic induced by light, metal ions (i.e., iron, copper, (Guardiola et al. 1996). Cholesterol oxides cobalt, manganese, etc.), or enzymes like may be formed when reheating chilled meat lipoxygenase. In the case of induction by or during the chilling storage of meat. No lipoxygenase, this enzyme needs activation cholesterol oxides were reported to be
