| 摘 要： | 研究温度、光照时间对辣木油抗氧化稳定性的影响，以此选择合理的保存方式。用石油醚浸出法制成辣木油试样，以过氧化值(POV)为试验指标，采用Sehaal烘箱法和室内自然光照射法进行试验，测定不同温度和不同受热、光照时间下的POV值并计算氧化诱导时间。结果表明:不同受热时间下测得的POV值之间的差异性不显著，而不同光照时间的POV值则具有显著性差异，说明辣木油对温度比较稳定，但对光照则相反，光照时间越长抗氧化的稳定性就越差，光照氧化诱导时间仅为3.5 d。提示了辣木油应在20℃左右保存并特别注意避光，在此条件下的货架期可达304 d。

| Abstract: | Anti-oxidation stability of moringa oil under different temperature and varied light tensity was studied to design reasonable method for storage. Moringa oil extracted by petroleum ether was studied by Sehaal-oven method and radiated by natural room light to evaluate the stability by the peroxide value (POV) and the time of oxidation inducement. The results showed that storage temperature didn't affect the POV value significantly, while the light did, which demonstrated that anti-oxidation stability of moringa oil was slightly affected by temperature while remarkably affected by light, and the anti-oxidation stability declined with the time of light radiation, for example, the oxidation inducement time was only 3.5 days, showing that moringa oil should avoid light at 20℃ when storage, and the shelf life can be as long as 304 days at such condition. |
