摘要 为了在工业化提取山药多糖及在保健品的研发方面奠定基础,分别考虑了超声波提取时间、料液比、超声波作用后水提时间和超声波功率等4个因素对山药多糖提取率的影响,做12个水平的实验,得出不同水平下的12组多糖提取率的数据,由此12组数据运用均匀设计法优化超声波辅助提取山药多糖的提取工艺,最终确定出提取山药多糖的最佳工艺条件为:超声波辅助提取时间为60min,料液比为1∶18,超声波作用后热水提取时间为120min,超声波功率为450w,在此工艺条件下测得多糖的提取率为31.56%。 Twelve experiments of different level were done considering the respective influence of extraction time of ultrasonic,the radio of material and water,the water extraction time of ultrasonic and the power of ultrasonic on the rate of polysaccharide extraction and then twelve groups of data were obtained.Based on these twelve groups of data,the optimal conditions for the extraction of Chinese yam polysaccharides optimized with uniform design were set as the following:the extraction time of ultrasonic was 60 min,the ratio of material and water was 1:18,the water extraction time of ultrasonic is 120 minutes and the power of ultrasonic was 450 w.Under this condition,31.56% of the polysaccharide extraction rate was obtained.
