| 摘 要： | 为了保证茶籽油的原生态品质,研究了茶籽仁油的超临界CO2萃取技术,并运用响应面法对其萃取压力、温度和时间等工艺条件进行了优化分析,得到的最佳工艺条件是在33 MPa压力和43℃温度下连续萃取时间2 h。此条件下的萃取得率为39.6%、出油效率达86.5%,所得茶籽油只需简单的脱酸处理即达到国标GB11765—2003规定的压榨一级茶籽油水平。

| Abstract: | The supercritical carbon dioxide extraction process of Camellia seed kernel oil was investigated and optimized by a response surface methodology.The optimum process parameters were extracted for 2 h at 33 MPa and 43 ℃.Under this optimal condition,the oil yield was 39.6% based on the weight of oil-tea Camellia seed kernel.The quality of the oil meeted the requirement of the primary pressing oil Camellia oil according to GB11765—2003. |
