| 中文摘要: |
| 采用湿法超微粉碎、水乳化萃取与冷冻破乳化释放的方法，以水为提取剂从茶籽仁中提取茶籽油。采用单因素及正交试验法，研究料液比、乳化萃取时间、冷冻温度、冷冻时间4个因素对茶籽油提取率的影响，优化水乳化萃取与冷冻破乳化释放组合提取茶籽油工艺条件。试验得到水乳化萃取与冷冻破乳化释放组合提取茶籽油的适宜工艺条件为料液比（茶籽仁与水的质量比）1∶?4、乳化萃取时间4.0 min、冷冻温度-15?℃、冷冻时间5.5 h，在此条件下茶籽油的提取率可达91.3%。 |
| 英文摘要: |
| The wet ultrafine grinding, water emulsification extraction and freezing demulsification release methods were used to extract oil-tea camellia seed oil with water as extraction agent. The effects of solid-liquid ratio, emulsification extraction time, freezing time, and freezing temperature on the extraction rate of oil-tea camellia seed oil were studied by single factor experiment and orthogonal experiment to optimize the extraction conditions. The results showed that the optimal extraction conditions of oil-tea camellia seed oil by water emulsification extraction and freezing demulsification release were obtained as follows: mass ratio of oil-tea camellia seed kernel to water 1∶?4, emulsification extraction time 4.0 min, freezing temperature-15?℃, and freezing time 5.5 h. Under these conditions, the extraction rate of oil-tea?camellia seed oil reached 91.3%. |
