为提高金针菇多糖的得率,采用超声波法辅助热水浸提进行金针菇多糖的制备.以干金针菇粉末为原料.正交试验综合分析超声波辅助提取金针菇多糖的得率.浸提过程中的主要因素依次为浸提温度、超声波处理时间、液料比对粗多糖得率的影响较大,确定了金针菇粗多糖浸提的最佳工艺条件,浸提温度55℃,超声波处理时间70 min,液固比20:1....

Process Conditions Optimization of Ultrasonic-assisted Hot Water Extraction on Flammunlina Velutipes Polysaccharides

To increase the yield rate of Flammunlina velutipes,ultrasonic-assisted hot water extraction was adopted preparation Flammunlina velutipes polysaccharide.As raw material,the dry flammunlina velutipes powder was studied on yield Flammunlina veluties polysaccharides under the ultrasonic assisted extraction that were comprehensive analyzed by orthogonal experiment.Experimental results showed that the major factors on extraction process were extraction temperature,ultrasonic time and liquid ratio,these factors had large influence on yield of polysaccharides.The optimum extraction conditions on Flammunlina veluties polysaccharides were determined that the extraction temperation were 55 ℃,the ultrasonic time was 70 min,liquid and solid ratio was 20∶1.With these conditions the yield of Flammunlina veluties polysaccharides was 8.77%.Ultrasonic-assisted Hot Water extraction was more preferable on the traditional water extraction obviously.
