响应曲面法优化软枣猕猴桃多糖超声辅助提取及乙醇沉淀工艺
Optimization of Ultrasonic-Assisted Extraction and Ethanol Precipitation of Polysaccharides from Actinidia arguta by Response Surface Methodology
摘要
Abstract
Response surface methodology was used to optimize technological parameters for ultrasonic-assisted extraction and ethanol precipitation of polysaccharides from Actinidia arguta Sieb.et Zucc..Three factors including ultrasonic power,ultrasonic time and solvent/material ratio were selected to maximize the yield of polysaccharides.Ethanol concentration,ethanol volume and precipitation time were selected to maximize the yield of polysaccharides precipitated by ethanol.The optimal ultrasonic-assisted extraction conditions were obtained as follows: ultrasonic power 260 W,ultrasonic treatment time 8 min,and solvent/material ratio 6:1(mL/g),resulting in a polysaccharide yield of 1.48%(m/m).The optimal conditions for precipitating polysaccharides from the crude polysaccharide solution obtained were achieved after 4 h precipitation with 7-fold volume of 90% ethanol,and a polysaccharide yield of 1.55%(m/m) was obtained under these conditions.关键词
