储藏条件对茶叶籽油品质的影响

以茶树的果实茶叶籽经初榨精炼得到的茶叶籽油为原料，模拟工厂实际情况，研究不同光照、温度及包装材质对茶叶籽油储藏过程中品质的影响。结果表明不同温度、光照及不同材质的容器储存条件下，茶叶籽油储藏385 d罗维朋比色红值、黄值、酸值及过氧化值增加均超过100%,饱和脂肪酸质量分数升高4.70%～10.80%,不饱和脂肪酸质量分数下降2.54%～20.36%,角鲨烯质量分数下降24.87%～50.30%,维生素E质量分数下降29.63%～66.67%。茶叶籽油储藏影响因素大小依次是温度、光照及包装材质。茶叶籽油储藏的最好的条件是低温避光玻璃材质，因此茶叶籽油的避光低温储藏是其必要的条件。不同储藏条件下的茶叶籽油罗维朋比色与品质显著相关，罗维朋比色可间接判断油的品质。本研究结果为茶叶籽油及其他油品的储藏及利用提供参考。

Effects of storage conditions on quality of tea seed oil

The effects of light, temperature and packaging material on the storage of tea seed oil were studied by using the tea seed oil extracted from the fruit of tea tree as raw material. The results showed that the rovippon, acid value and peroxide value of tea seed oil increased by more than 100%, saturated fatty acid increased by 4.70%-10.80%, unsaturated fatty acid content decreased by 2.54%-20.36%, squalene content decreased by 24.87%-50.30% and vitamin E content decreased by 29.63%-66.67%.Temperature had the most significant effect on the quality of tea seed oil,followed by light and packaging material. The best storage condition of tea seed oil is the glass material with low temperature and keep in dark place. Therefore,the storage of tea seed oil must be stored away from light at low temperature. The quality of tea seed oil under different storage conditions was significantly correlated with lovippon. Lovippon indirectly judged the quality of oil. This study provides theoretical reference for the storage and utilization of tea seed oil and other oils.
