摘要
选取了AOT/SDS两种阴离子表面活性剂复配形成反胶束体系,讨论了该复配体系用于大豆、鹰嘴豆、葵花籽饼粕蛋白前萃取的主要影响因素。通过对增溶水量W0的测定,确定了溶剂异辛烷与助溶剂正辛醇最佳配比为5∶1,最佳萃取温度为40℃;讨论了在不同增溶水量W0和植物饼粕加入量对萃取率的影响;通过正交试验确定大豆合理萃取工艺条件温度为40℃、W0为37.6、豆粉加入量为0.07 g/mL,萃取率为87%,鹰嘴豆合理萃取工艺条件为40℃、W0为32.9、豆粉加入量为0.07 g/mL,萃取率为85.2%。
Two anionic surfactants, AOT and SDS, were selected to form a complex -reverse micelles system. The complex - reverse micelles system was applied to extract the protein in soybean meal, chickpea meal and sunflower meal, and the main influence factors on the extraction rate of protein were discussed. By determining the amount of dissolved water （W0 ）, the optimal technology conditions for the system were found to be W（ isooctane）： W（Octanol） = 5 ： 1 and temperature 40 ℃. The effects of different W0 and meal amount on the extraction rate were also discussed. Finally, the extraction conditions for soybean meal and chickpea meal were optimized through orthogonal tests. Results： The optimal extraction conditions for soybean meal are temperature 40℃, W0 37.6 and meal amount 0.07 g/mL,thus the extraction yield is 87% ; and for chickpea meal are temperature 40 ℃, W0 32.9 and meal amount 0.07 g/m,thus the extraction rate is 85.2%.
