| 中文摘要: |
| 以元宝枫籽油为原料，过氧化值 (POV)、酸值 (AV) 及TBA值为氧化稳定性指标，研究温度、光照、空气、包装瓶材质和包装瓶颜色对元宝枫籽油氧化稳定性的影响，进一步建立氧化动力学模型，预测元宝枫籽油的货架期。结果表明：元宝枫籽油在低温、避光、无氧、不锈钢或陶瓷材质、蓝色或绿色玻璃瓶等储藏条件下，POV、AV、TBA值均增长缓慢，氧化稳定性好；元宝枫籽油的氧化过程遵循零级反应动力学方程，经验证POV模型预测值与实测值较为接近；元宝枫籽油在20、25 ℃密封避光储藏条件下的货架期预测值分别为516、335 d。 |
| 英文摘要: |
| Taking Acer truncatum seed oil as the raw material and the peroxide value (POV), acid value (AV) and 2-thiobarbituric acid (TBA) value as indicators for its oxidation stability, the effects of storage conditions such as temperature, light, air, bottle material and color on the oxidation stability of Acer truncatum seed oil were studied. The oxidation kinetic model was further established to predict the shelf life of Acer truncatum seed oil. The results showed that under storage conditions of low-temperature, light-proof, oxygen-free and with packaging materials of stainless steel, ceramics, or glass tinted in blue/green, the POV, AV and TBA values of Acer truncatum seed oil only grew very slowly, showing strong oxidation stability. The oxidation process followed the zero-order reaction kinetics, and the POV matched the predicted values according to the kinetic model. The shelf life of Acer truncatum seed oil under sealed and dark storage conditions was estimated to be 516 d and 335 d at 20 ℃ and 25 ℃, respectively. |
