豆豉类黑精超声提取工艺研究

Optimization of Ultrasonic Extraction Technology for Aspergillus-type Douchi Melanoidin

为了优化超声法提取豆豉类黑精的最佳工艺条件,本文以水为提取剂,通过单因素实验以及超声功率、料液比和超声时间L9(33)正交实验,得出最优超声方法为超声功率180 W,料液比1∶10,超声时间9 min。超声波提取色素的最佳工艺条件的吸光值为0.240。

In order to gain the extraction rate of Aspergillus-type Douchi Melanoidin,the single factor experiment is designed to study the effect of ultrasonic power,ratio of solid to solvent,ultrasonic time.The optimal extraction conditions of Aspergillus-type Douchi melanoidin are ultrasonic power 180 W,atio of solid to solvent 1∶10,ultrasonic time 9 min.The experimental verification of the optimum technological conditions of ultrasonic extraction showed that the absorbance value was 0.240.The process is efficient,energy and time saving and can be used as the experimental base of industrial production.
