SUPERCRITICAL FLUID EXTRACTION AND ELECTROCHEMICAL CHARACTERIZATION OF MYCOTOXINS

真菌毒素是由某些真菌菌株产生的一类化合物 或模具。 这些化合物可能有毒。 人类健康危害和 霉菌毒素可能对实验动物健康造成危害 被污染的食物。 本延续项目的目的如下：（1）开发一个 一种利用超临界流体萃取（SFE）来萃取 花生酱和谷物中的黄曲霉毒素，（2）继续研究循环 霉菌毒素-黄曲霉毒素B1，B2，G1，G2， 黄曲霉毒素和棒曲霉素，使用电化学还原在不同的pH值 （3）确定电子转移的数量，并提出 可能的有机机制，（4）确定 黄曲霉毒素加标样品的回收率百分比。 本科生的知识将通过操作来提高 极谱仪、HPLC仪、超临界萃取仪。 知识 还将获得分析技能，技术和演示文稿。

Mycotoxins are a class of compounds produced by certain strains of fungi or molds. These compounds may be toxic. Human health hazards and laboratory animals health hazards are possibly due to mycotoxin contaminated foods. The continuation project purposes are as follows: (1) To develop a method using supercritical fluid extraction (SFE) for extraction of aflatoxins from peanut butter and grains, (2) To continue to study cyclic voltammetry properties of mycotoxins - Aflatoxins B1, B2, G1, G2, aflatoxicol, and patulin using electrochemical reduction in various pH media, (3) To determine the number of electrons transferred and propose the possible organic mechanisms involved, and (4) To determine the percentage recoveries of spiked samples of aflatoxins. Undergraduate students knowledge will be enhanced by operating polarographic equipment HPLC instrument, and SFE equipment. Knowledge will also be gained with analytical skills, techniques and presentations.
