摘　　要：探讨β-环糊精对冰糖橙汁除苦的最佳添加量、最佳作用温度和最佳作用时间。实验以除苦剂β-环糊精的五个添加量0.60 g/L、0.65 g/L、0.70 g/L、0.75 g/L、0.80 g/L,五个加热温度30℃、35℃、40℃、45℃、50℃和五个除苦时间5 min、10 min、15 min、20 min、25 min作为单因素进行实验,初步确定除苦最佳条件。通过单因素实验结果设计正交实验,并以正交实验的分析结果来优化冰糖橙汁除苦的最佳条件。单因素实验结果表明:β-环糊精的最佳添加量0.65 g/L,最佳作用温度30℃,最佳作用时间10 min;通过正交实验发现,β-环糊精的最佳添加量0.70 g/L,最佳作用温度25℃,最佳作用时间10 min。利用β-环糊精对冰糖橙汁进行除苦方法可行,冰糖橙汁苦味得到有效改善。In this paper,the optimum amount of addition,temperature and time of action onβ-cyclodextrin as a bitter agent in the juice of crystal sugar orange were studied.The optimum conditions for the removal of bitterness onβ-cyclodextrin were determined by the single factor of five addition amounts(0.60 g/L,0.65 g/L,0.70 g/L,0.75 g/L and 0.80 g/L),five heating temperatures(30℃,35℃,40℃,45℃and 50℃)and five removal times(5,10,15,20 and 25 minutes)ofβ-cyclodextrin respectively.The optimum condition of removing bitterness was optimized by the result of orthogonal experiment based on the result of single factor experiment.The results of single factor experiment showed that the optimum dosage ofβ-cyclodextrin was 0.65 g/L,the optimum temperature was 30℃,and the optimum time was 10 min respectively.However,orthogonal experiments showed that the optimal addition amount ofβ-cyclodextrin was 0.70 g/L,the optimal temperature was 25℃,and the optimal time was 10 min respectively.Therefore,it is feasible and effective to employβ-cyclodextrin to remove the bitter taste of crystal sugar orange juice.
