中文摘要: 为优化油茶饼粕多糖的超声波辅助提取工艺,在单因素试验的基础上,运用响应面分析法,研究超声波提取温度、超声功率、超声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,并确定超声波辅助提取油茶饼粕多糖最佳条件为:超声波提取温度58℃,超声波处理时间20 min,超声波功率440 W,料液比选用单因素试验得到的最佳水平220∶1(mL/g),此时得到的平均提取率为10.31%。
Abstract:The ultrasonic wave-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(ultrasonic wave power,ultrasonic wave 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 ultrasonic wave-assisted extraction conditions were obtained as follows:ultrasonic wave power of 440 W for 20 min with liquid-solid ratio of 220∶1(mL/g)and extraction temperature of 58℃,resulting in a polysaccharide yield as high as 10.31%.
