摘要

摘要: 为保证超临界萃取技术高效萃取高品质茶籽油,运用微波前处理加以辅助,利用正交设计得到最佳微波处理条件为:原料水分7.8%,粉碎粒度为过100目筛,微波处理120s。再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,得到最佳工艺条件为:在33MPa压力和45℃温度下连续萃取时间2h。此条件下的萃取效率高达92.76%,远高于未经微波处理的方法。该工艺所得茶籽油VE含量高达182.4mg/kg,只需简单脱酸即达到压榨一级茶籽油标准。

Abstract: The supercritical carbon dioxide extraction process combined with microwave pretreatment for efficiently extracting high quality camellia seed oil was investigated. Orthogonal test was used to determine the optimal conditions of microwave pretreatment. The optimum process parameters obtained were as follows:camellia seed flour with moisture content 7.8% and through a 100 mesh sieve was treated by microwave for 120 s. Then the supercritical carbon dioxide extraction process was optimized by response surface methodology. The optimum process parameters obtained were extracting for 2h at 33 MPa and 45℃. Under this optimum condition, the oil extraction efficiency was 92.76% and was far higher than that without microwave processing method. The extracted oil with a satisfying VEcontent of 182.4mg/kg could meet the requirement of the pressing first class camellia oil followed by simple deacidification process.
