Gualouzi oil is rich in poly - unsaturated fatty acids and is very easy oxidated. The change pf temperature,storage time, and light whether visible light and ultraviolet radiation, etc, can affect the automatic oxidation of gualouzi oil, and high temperature and ultraviolet radiation can expedite the oxidation, bringing especial odor matter, such as alde- hyde, acid, etc. The influences of ray, temperature, ultraviolet radiation and storage time on gualouz oil were studied. Results show that among theses factors the greatest influence is from high temperature. So, storage at a relatively low t...
