摘要
通过均匀设计实验优化新鲜菊芋预处理工艺,得到最佳工艺条件为:在100℃条件下烫漂10min,再在50℃干制7h。采用微波辅助提取工艺可有效提取菊芋中的菊粉,通过正交实验得到微波辅助提取菊粉的最佳工艺条件是:菊芋与水固液比1∶18,功率400W,微波作用270s,在95℃条件下提取40min,菊粉提取率高达99%。
The pretreatment process of fresh Jerusalem anichoke is achieved by the uniform design, and the optimized process is obtained as follows: the fresh Jerusalem anichoke is scalded for lOmin at 100℃, then desiccated for 7h at 50℃. The inulin from Jerusalem anichoke is extracted effectively by microwave-assisted extraction, and the optimized process is as follows:1:18 of Jerusalem anichoke to water, microwave power at 400W for 270s, further extraction at 95℃ for 40min. Under this optimal condition the rate of extraction is 99%.
