摘要
以泥鳅为原料,采用超声波辅助技术提取泥鳅多糖,运用硫酸-苯酚法检测泥鳅多糖的含量,利用单因素试验结果设计正交试验,探讨料液比、超声时间和超声功率对泥鳅多糖提取率的影响。经工艺优化,获得超声波提取泥鳅多糖的最佳工艺为料液比1∶20、超声时间20 min、超声功率100 W,在最佳工艺条件下提取泥鳅多糖提取率最高,达到2.79%。
Using loach as a raw material, adopting ultrasonic assisted extraction technique of polysaccharide loach, and using sulfuric acid - phenol assay of polysaccharide, the orthogonal experimental were designed through single factor to explore the effect of solid - liquid ratio, ultrasonic time and ultrasonic power on loach polysaccharide extraction rate. Through process optimization, the optimal technique by ultrasonic extraction of loach polysaccharide was obtained that material liquid ratio 1 : 20, ultrasonic time 20 min, ultrasonic power 100 W. The extraction rate of loach polysaccharide was the highest under the optimum conditions, reaching 2. 79%.
