摘要:

利用超临界二氧化碳萃取技术提取黑加仑籽油,运用响应面法优化萃取工艺条件。在单因素试验基础上,以萃取压力、萃取温度、萃取时间为响应因素,黑加仑籽油出油率为响应值,根据中心组合Box-Benhnken 试验设计原理采用三因素三水平的响应面分析法,确定各工艺条件对出油率的影响。结果表明:超临界二氧化碳萃取黑加仑籽油的最佳工艺条件为萃取压力33MPa、萃取温度38℃、萃取时间180min,在此条件下,黑加仑籽油出油率达到14%,与理论值基本一致。

Abstract:

The present study aimed to optimize the supercritical carbon dioxide extraction of blackcurrant seed oil using response surface methodology combined with a 3-variable, 3- level Box-Benhnken central composite design (CCD) on the basis of single factor experiments. Results showed that the optimal extraction for 180 min at 33 MPa and 38 ℃ resulted in a blackcurrant seed oil yield of up to 14%.

Key words: blackcurrant seed oil, supercritical carbon dioxide extraction, response surface methodology
