摘　　要：研究了丁二酸二异辛酯磺酸钠(AOT)/异辛烷反胶束萃取花生蛋白后萃的传质过程,分析了反胶束萃取花生蛋白传质控制步骤并选取模型。后萃考察了改变振荡速率、AOT浓度、前萃花生粉添加量等条件的影响,结果表明,振荡速率对后萃的影响不显著,AOT浓度过大、花生粉添加量过高均会使传质速率降低,判定反胶束后萃花生蛋白受界面反应控制的影响显著。This study evaluated the backward extraction mass transfer process of peanut protein extracted by sodium bis（2-ethylhexyl） sulfosuccinate（AOT）/isooctane reverse micelles using corresponding models. The effects of stirring speed, concentration of AOT, solid-liquid ratio on backward extraction rate were examined. The results showed that the backward extraction rate decreased with too high concentration of AOT and solid-liquid ratio. The stirring speed had no significant effect on backward extraction rate. The results showed that the backward extraction in this system was controlled by interface solubilization.
