| 中文摘要: |
| 以黑果枸杞籽油为研究对象，探究黑果枸杞籽油储藏过程中，水、空气、温度、金属离子、光照、抗氧化剂对其过氧化值（POV）的影响。结果表明：黑果枸杞籽油在避光、密封、低温、含有少量水的条件下储藏，其POV增长慢于对照组；添加不同金属离子的黑果枸杞籽油在（100±1） ℃储藏132 h，POV从高到低依次为FeCl3>MnSO4>K2SO4>CuSO4 >对照组>NaCl>MgCl2>AlCl3>CaCl2>ZnCl2，其中添加了FeCl3、MnSO4、K2SO4、CuSO4升高了黑果枸杞籽油的POV，而添加MgCl2、AlCl3、NaCl、CaCl2、ZnCl2降低了黑果枸杞籽油的POV，但降低效果不明显；加入抗氧化剂的黑果枸杞籽油的POV均低于对照组，抗氧化能力依次为TBHQ+BHA>TBHQ+VE>TBHQ>BHA>BHA+VE>VE。 |
| 英文摘要: |
| 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. |
