摘要
以菊芋为原料,采用热水浸提法提取菊粉,在提取温度、时间、料液比、pH值和提取次数等单因素试验的基础上,采用均匀设计对热水提取菊粉的工艺参数进行优选,并进行了验证试验.结果表明,在提取温度68℃,提取时间70 min,料液比1∶21,提取次数2次的条件下,菊粉提取率可达到16.04%.
Helianthus tuberosus L.was used as the raw material for extracting inulin with extraction of hot water.On the base of single factor screening,such as temperature,time,volume of adding water,pH and times of extraction,the uniform design was adopted for getting the optimal mixed technique parameters,and was verified by experiment.The result indicated that extraction rate of inulin reached 16.04 % with temperature at 68 ℃,for 70 minutes,1∶21 of ratio of liquid to material and 2 times of extraction.
