摘　　要：采用自行设计的连续动态萃取系统对大蒜加工废水中的大蒜素进行连续动态提取研究。以大蒜加工废水为原料,以植物油抽提溶剂为提取溶剂,做大蒜素提取单因素试验。在单因素试验的基础上,采用Box-Behnken试验设计和响应面(RSM)分析法,以大蒜素得率及提取率为响应值绘制响应面图和等高线图,建立大蒜素连续动态提取的二次回归方程。考察连续循环次数、有机溶剂体积分数及连续进样速度对大蒜素提取量及提取率的影响。试验结果表明:连续循环次数对大蒜素得率及提取率的影响最大,有机溶剂体积分数次之,连续进样速度对其影响最小。通过联合求解法确定大蒜素最佳提取参数是:连续循环次数4次,有机溶剂体积分数50%,大蒜加工废水连续进样速度4 cm/s。在此条件下做3次重复试验,测得大蒜素得率为75.098 mg/L,大蒜素提取率为87.450%。The continuous dynamic extraction system was used for the dynamic extraction of allicin from the processing wastewater of garlic chips.The raw material processing wastewater of garlic chips and solvent for vegetable oils extraction were used as extraction solvent.Box-Behnken experimental design and response surface(RSM)analysis method were based on the single factor experiments,and the response surface graph and contour map were plotted with the yield and extraction rate of allicin as response value,and the two regression equations for dynamic extraction of allicin were established.The effects of continuous cycle times,organic solvent volume fraction and continuous injection rate on the yield and extraction rate of allicin were investigated.It was found that the continuous cycle times had the greatest effect on the yield and the extraction rate of allicin,then was the organic solvent volume fraction and the continuous injection rate had the least effect.The joint extraction method which used to determine the optimal extraction parameters of allicin were continuous cycle times 4,the organic solvent volume fraction 50%,and the continuous injection rate 4 cm/s.Under this condition,the yield of allicin was 75.098 mg/L.The extraction rate of allicin was 87.450%.
