色谱及质谱检测技术在食品真菌毒素检测中的应用研究

Application of Chromatographic and Mass Spectrometry in the Detection of Mycotoxins in Food

为了检测食品中的真菌毒素,本文对其检测流程及步骤进行深入分析,并提出同时使用色谱及质谱检测技术对粮食承储企业稻谷的真菌毒素进行检测。研究发现,在加标量为2~800μg·kg^(-1)时,粮食中6种真菌毒素的平均回收率为75.5%~102.5%,批内的相对标准偏差为3.7%~9.7%,均满足食品理化检测要求。由此可知,色谱及质谱检测技术适用于对粮食中多组分真菌毒素进行定量与定性检测。

In order to detect mycotoxins in food,this paper deeply analyzes the detection process and steps,and proposes to simultaneously use chromatography and mass spectrometry detection technology to detect mycotoxins in grain storage enterprises.Research has found that when adding scalars ranging from 2~800μg·kg^(-1),the average recoveries of six mycotoxins in grain were 75.5%~102.5%,and the relative standard deviation within the batch was 3.7%~9.7%.All of them met the requirements of food physical and chemical detection.
