Lycium ruthenicum Murray seed oil was used as the research object to investigate the effect of water, air, temperature, metal ions, light and antioxidants on the POV of Lycium ruthenicum Murray seed oil. The results showed that the POV of Lycium ruthenicum Murray seed oil increased slowly under the conditions of avoiding light, sealing, low temperature and containing a small amount of water. The Lycium ruthenicum Murray seed oil added with metal ions was stored for 132 h at (100±1) ℃, the POV of each group decreased in the order: FeCl3>MnSO4>K2SO4>CuSO4>control>NaCl>MgCl2>AlCl3>CaCl2>ZnCl2. The addition of FeCl3, MnSO4, K2SO4 and CuSO4 increased the POV of Lycium ruthenicum Murray seed oil, while MgCl2, AlCl3, NaCl, CaCl2 and ZnCl2 slightly reduced the POV. The POV of each group of Lycium ruthenicum Murray seed oil added with antioxidant was lower than that of the control, and the antoxidation ability decreased in the order : TBHQ+BHA>TBHQ+VE>TBHQ>BHA>BHA+VE> VE. |
