采用正交试验优化超临界CO2萃取茶油并对其稳定性进行研究. 以茶油的出油率为指标,考察茶子的粒度、萃取温度、压强及时间对出油率的影响并测定茶油储存期间的酸值和过氧化值,分析其产品的稳定性. 结果表明,超临界CO2萃取茶油的最佳工艺为粒度20目的茶子粉,温度45℃、压强30 Mp下萃取2.5 h,茶油的出油率达97.26%;该工艺下提取的茶油在阴凉避光处储藏18个月质量稳定.
採用正交試驗優化超臨界CO2萃取茶油併對其穩定性進行研究. 以茶油的齣油率為指標,攷察茶子的粒度、萃取溫度、壓彊及時間對齣油率的影響併測定茶油儲存期間的痠值和過氧化值,分析其產品的穩定性. 結果錶明,超臨界CO2萃取茶油的最佳工藝為粒度20目的茶子粉,溫度45℃、壓彊30 Mp下萃取2.5 h,茶油的齣油率達97.26%;該工藝下提取的茶油在陰涼避光處儲藏18箇月質量穩定.

Optimized the supercritical CO2 extraction of camellia oil by orthogonal test and studied on its stability. With the oil rate of camellia oil as the index,inspected the influence of oil rate by the size of the camellia,supercritical CO2 extraction temperature pressure and extraction time, and measured the acid value and peroxide value during the camellia oil storage, stability analysis of its products. The results showed that the optimum technology of supercritical CO2 extraction of camellia oil were the size was 20 meshes,the temperature was 45℃,the pressure was 30 Mp,the time was 2.5 h. And with this method the extraction rate of the camellia reached to 97.26%. The camellia oil extracted by this process storaged of 18 months in a cool dark place was stable.
