Optimization of Ultrasonic-assisted Extraction Technology of Lentinan Polysaccharides by Response Surface Methodology and its Antioxidant Activity

中文摘要英文摘要

采用响应曲面对超声波辅助热水浸提香菇多糖提取条件进行优化,优化后的工艺为:水料比37:1,超声功率550 W,超声时间7.3min,多糖得率实际测定值为20.58%,与模型预测值22.37%接近,表明用响应面方法来优化香菇多糖提取工艺是可行的.与传统的热水煎煮工艺相比,采用超声波辅助热水浸提的方法提取香菇多糖,可使多糖得率提高33.29%,能耗降低55.51%.测定香菇提取液对1,1-二苯基-2-苦味酰基自由基(DPPH·)的清除能力,结果表明,…查看全部>>

The response surface methodology was used to optimize the ultrasonic-assisted boiling water extraction of lentinan polysaccharides. Design expert analysis indicated that the optimal processing conditions were: water to solid ratio 37∶1, ultrasonic power 550W and ultrasonic extraction time 7.3min, respectively. The extraction yield of lentinan polysaccharide is 20.58% which is close to the predicted value of 22.37%, indicated that using the response s…查看全部>>
