中文摘要: 为优化油茶饼粕多糖的微波辅助提取工艺,在单因素试验的基础上,运用响应面分析法,研究料液比、微波功率、微波提取时间对多糖提取率的影响。建立多糖提取率的二次回归方程,并确定微波辅助提取油茶饼粕多糖最佳条件为:料液比1∶170(g/mL),微波处理时间126 s,微波功率610 W,此时得到的平均提取率为8.78%。
Abstract:The microwave-assisted extraction of polysaccharides from camellia seed cake was optimized by response surface methodology.According to the single factor experiment,three levels of the factors(microwavepower,microwave irradiation time,solid-liquid ratio)were selected for the Box-Behnken factorial design to establish a quadric regression equation for describing the yield of polysaccharides.By response surface analysis,the optimal microwave-assisted extraction conditions were obtained as follows:microwave power of 610 W for 126 s with solid-liquid ratio of 1 ∶170(g/mL),resulting in a polysaccharide yield as high as 8.78%.
