响应面法优化提取甘蔗皮中蔗蜡的工艺条件
首发时间:2013-03-06
摘要:采用响应面(RSM)优化溶剂法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进行三因素三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7.07mL/g,提取时间2.14h,最大提取率为7.14%。

Optimization of Extraction of Sugarcane wax from Sugarcane skin by Response Surface Methodology
Abstract:The experiment is designed to get the optimum technological extraction conditions of Sugarcane wax from sugarcane skin by Response Surface Methodology (RSM). Ratio of solvent, solid-liquid ratio and extraction time were selected as causal factors and yield of sugarcane wax were used as responsive values. Based on the single factor experiments, a three-factor-three-level experiments design were developed by Box-Benhnken central composite design method.The results demonstrated that the optimum conditions for extracting sugarcane wax from sugarcane skin were as follows: ratio of solvent is 49.96%, solid-liquid ratio is 7.07 mL/g and extracting time is 2.14 h. Under the optimum extraction technology condition, the yield of sugarcane wax is 7.14%.
