黄曲霉毒素(aflatoxin,AF)是由黄曲霉(Aspergillusflavus)和寄生曲霉(Aspergillusparasiticus)等真菌侵染农产品、食品、饲料等产生的一类次生代谢物[1]。最为常见的有AFB1、AFB2、AFG1、AFG2,主要分布于霉变的花生、谷物、果仁和大米等食物中,其中AFB1的存在量与毒性都是最大的,其毒性是氰化物的10倍,砒霜的68倍[2]。人们食用被污染的食品后导致急性中毒,引起肝坏死;慢性中毒则可引发肝癌、胃癌、食道癌等严重疾病[3]。目前检测黄曲霉毒素主要有:薄层色谱法[4]、酶联免疫法(ELISA法)[5]、高效液
Aflatoxin (AF) is a kind of secondary metabolite produced by fungi such as Aspergillus flavus and Aspergillus parasiticus in agricultural products, food and feedstuffs. AFB1, AFB2, AFG1 and AFG2 are the most common, which are mainly distributed in mildewed peanuts, cereals, nuts and rice, among which AFB1 is present in the largest amount and toxicity and its toxicity is 10 times that of cyanide. Arsenic Cream 68 times [2]. People eat contaminated food leading to acute poisoning, causing liver necrosis; chronic poisoning can cause liver cancer, stomach cancer, esophageal cancer and other serious diseases [3]. Currently detected aflatoxins are: thin layer chromatography [4], enzyme-linked immunosorbent assay (ELISA) [5], high-performance liquid
