黄曲霉毒素B_1、棕曲霉毒素A、桔霉素是曲霉和青霉属的代谢产物,属于致癌物质,对人、畜、禽的肝、肾有毒害作用。酱油又是用曲霉和青霉发酵生产的,故开展对酱油中三毒素的检测研究很有意义,过去曾有微生物检测法、薄层色谱法、紫外分光光度法;但这些方法均不够理想,我们用高效液相色谱法检测,操作简便、快速、灵敏、准确。 Aflatoxin B_1, Aspergillus toxin A and Citrinin are the metabolites of Aspergillus and Penicillium, which are carcinogenic substances and toxic to the liver and kidney of people, livestock and poultry. Soy sauce is produced by fermenting with Aspergillus and Penicillium. Therefore, it is of great significance to carry out research on the detection of three toxins in soy sauce. In the past, microbial detection, TLC and UV spectrophotometry were used. However, these methods are not ideal, We use high-performance liquid chromatography detection, easy to operate, fast, sensitive and accurate.
