Oxidation in fish lipids during thermal stress as studied by 13 C nuclear magnetic resonance spectroscopy
Abstract 13 C Nuclear magnetic resonance spectroscopy has been applied to elucidate the mechanism of lipid oxidation occurring during thermal treatment of fish. Effects of temperature and time of processing have been studied by means of a model system of lipids, extracted from salmon ( Salmo salar )...
