Detection and Risk Analysis of Pesticide Residue from Dried Pepper and Dried Prickly Ash in Different Habitats and Varieties
This paper used dried pepper such as line pepper,small pepper,new generation pepper,Yan pepper and Indian pepper from Xinjiang Province,Henan Province,Zunyi City and India,and dried prickly ash from Jiangjin City,Wudu City,Xichang City and Maoxian City as experimental materials,in order to detect 34 kinds of pesticide residues,using gas chromatography-mass spectrometry technology.A total of 36 batches of dried pepper were detected,and 28 batches were detected with pesticide residues,accounting for 77.8％.The main pesticides detected were hexazolol,pentazolol,isoprocarb,dimepenthalin,cyhalothrin,propion bromide and bifenthrin.A total of 39 batches of dried prickly ash were detected,and pesticide residues were detected in 11 batches,accounting for 28.2％.The main pesticides detected were methanophos,fluazolium ring,methanoxime,nitrilazolium and methanophosphone.Combined with the pesticide residue content of spices in GB 2763-2021"National Standards for Food Safety Maximum Limit of Pesticide Residue in Food",the pesticide residue risk of dried pepper and dried prickly ash in different habitats and varieties was analyzed.The results showed that the pesticide residue content of all samples was within the safe limit,and the excess rate was zero.
