英文摘要:

      Objective To design a new kind of extraction and purification device of synthetic colorants in foodstuff. Methods The novel extraction and purification device was designed based on the polyamide powder adsorption and experimental processes. The key module of device was the vacuum switch tube with three-way glass stopcock which was composed of inclined hole three-way piston connected internal grinding joint and external grinding joint with buffer vacuum tube from top to down respectively. Three modes of purification, desorption and preparation could be realized by the changes of rotation position with inclined hole three-way piston. A complete extraction and purification device consisted of the key module, surge flask and vacuum pump. Results The single sample treatment could be realized with the single extraction and purification device. Not merely a single sample but also many samples could be processed with the parallel extraction and purification device simultaneously. The preparation, purification and desorption process of different samples could be carried out at the same time, and did not influence each other. Conclusion The novel extraction and purification device can not only shorten the experiment time and improve the work efficiency but also reduce the loss of the target, which is suitable for the extraction and purification of synthetic colorants in foodstuff.
