Initiation and propagation of lipid oxidation are catalyzed by exposure to oxygen, exposure to light, the presence of pigments such as chlorophyll, riboflavin and hemo proteins, the presence of metals, and the contact with lipoxygenase (Mistry & Min, 1997).
When oxygen is present, unsaturated fatty acid decomposition
occurs more readily. These suggest low temperature, low oxygen
and quick processing can help to avoid the lipid oxidation. The
microwave-vacuum (MV) heating technology not only have the
advantages of microwave heating (heating rapidly, high efficiency,
