中文摘要: 以榛菇为试验材料，以榛菇多糖提取得率为考察指标，首先对超声波法提取多糖的提取温度，料液比、提取 时间、超声波功率进行单因素试验，在此基础上，采用响应面试验进一步对榛菇多糖提取工艺进行优化。结果表明：榛 菇多糖的最佳提取工艺为液料比 20 ∶ 1（mL/g），超声波时间 75 min，提取温度 60 ℃，超声波功率 70 W，在此条件下， 榛菇多糖提取得率为 6.56 %。
Abstract:Mellea armillaria sporophore was used as experimental material， whose extraction rate of polysac－ charide as important examining index， single factor test of material liquid ratio， exaction time， exaction tem－ perature and ultrasonic power were studied. On the basis of this， orthogonal test of four factors and three levels were used to optimize the extraction process of olysaccharide from mellea armillaria sporophore. The optimal ex－ traction process were as follows， material liquid ratio was 20 ∶ 1， ultrasonic time was 75 min， extraction tem－ perature was 60 ℃ and ultrasonic power was 70 W.Under these conditions， the extraction rate of polysaccharide from mellea armillaria sporophore was 6.56 %.
