摘　　要：采用苯基硼酸/季铵盐离子对溶剂萃取塔格糖。通过单因素实验,考察pH、苯基硼酸浓度、溶剂比对塔格糖萃取率和选择性的影响。进一步利用响应面分析优化得到最佳萃取条件为:pH11.0,苯基硼酸浓度0.10mol/L,溶剂比1.0,此时塔格糖的萃取率为65.7%,选择性系数为36.8,塔格糖的回收率为92.3%。The extraction of tagatose by an ion-pair solvent of phenyloronate acid and quaternary ammonium was investigated.The influence of pH,PBA concentration and volume ratio（ O/W） on extraction rate of tagatose and the selectivity of tagatose extraction from the aqueous solution were examined. It was showed that the optimial conditions were pH11.0,PBA concentration 0.10 mol/L and volume ratio（ O/W） 1.0 using Central Composite Facecentered Experimental Design by Design Expert Version 7.1.6 （ Stat-Ease,USA） ,and in this condition,the extraction percentage,selectivity for tagatose and the recovery extraction percentage was obtained to be 65.7%, 36.8 and 92.3%,respectively.
