摘 要: 以甘蔗皮为原料,利用两步法提取蔗蜡,并采用响应面法(response surface methodology,RSM)优化从甘蔗皮中提取甘蔗蜡的工艺条件,在单因素试验的基础上,选择溶剂配比、料液比、提取时间为自变量,蔗蜡提取率为响应值,以Box-Benhnken的中心组合试验方法结合3因素3水平的设计方案进行响应面分析。结果表明,溶剂法提甘蔗蜡最佳工艺条件为:溶剂配比49.96%,料液比7.07 mL/g,提取时间2.14 h,最大提取率为7.07%,为预测值的99.02%.

Abstract: This study took sugarcane rind as the raw material and used two-step method to extract sugarcane wax. The experiment was designed to get the optimum technological extraction conditions of sugarcane wax from sugarcane skin by response surface methodology (RSM). The ratio of solvent, solid-liquid ratio and extraction time were selected as causal factors and yield of sugarcane wax was used as responsive values. Based on the single factor experiments, a three-factor-three-level experiment design was developed by Box-Benhnken central composite design method. The results demonstrated that the optimum conditions for extracting sugarcane wax from sugarcane rind were as the following: ratio of solvent was 49.96%, solid-liquid ratio was 7.07 mL/g and extracting time is 2.14 h. The practical sugarcane wax extraction rate was 7.07%, which was well matched with the predicted value by 99.02%.
