牡丹籽油超临界二氧化碳萃取工艺（Supercritical Carbon Dioxide Extraction of Paeonia suffruticosa Andr. Seed Oil）
牡丹籽油 超临界二氧化碳萃取 中心复合设计
2009/12/28
以牡丹籽为原料，利用超临界CO2萃取提取牡丹籽油。采用单因素试验对影响牡丹籽油得率的5个影响因素（筛分粒度、CO2流量、压力、温度和时间）进行考察。以油得率为响应目标，对3个主要影响因素（筛分粒度、压力和温度）运用中心复合设计法，并经响应面法优化分析得到二次多项式回归方程预测模型，确定了超临界CO2萃取牡丹籽油的最佳条件为：筛分粒度60目，CO2流量20L/h，压力35MPa，温度45℃，时间12...
