摘要
Abstract the detection of pesticide residues in agricultural products is an important issue related to food safety. In recent years, gc-msms technology, as an efficient method for the detection of pesticide residues in agricultural products, has become a hot research topic at home and abroad. In this paper, gc-msms was used to screen 50 kinds of pesticide residues in Zanthoxylum bungeanum in Jiangjin area. In this paper, 50 kinds of common pesticides in Zanthoxylum bungeanum in Jiangjin area were tested. In this paper, the first step is to grind and soak the prickly ash to extract the detection solution, then purify the detection solution, and then test the detection solution. Through the results of this study, gc-msms method has high sensitivity, which can be accurate to 4.00ng/ml, and 5.6min can detect 50 pesticide residues at the same time. Through the experimental data, we can analyze the impact of pesticide residues on the organic matter in prickly ash.
