CHEMICAL COMPOSITION AND RESISTANCE OF LINSEED OIL TOWARDS OXIDATION
Abstract
The content of fatty acids, fat-soluble vitamins and other minor biologically active substances in various samples of linseed oil of cold expression was determined. Kinetic relationships have been obtained reflecting accumulation of primary and secondary oxidation products and free fatty acids in the linseed oil, as well as depletion in tocopherol and carotinoid contents during storage at room temperature in the absence and in the presence of atmospheric oxygen. The linseed oil has been shown to be sufficiently resistant towards oxidative aging, provided that the recommended storage conditions are met, owing to a complex of antioxidants and their synergic agents present in the oil. Using chromato-mass spectrometry, volatile products of oxidative destruction of linseed oil lipids have been identified.
