Abstract

The invention relates to a method for determining pesticide residues, in particular to a method for detecting organic phosphorus pesticide residues in wine. A sample pretreatment method for liquid-liquid direct extraction is established, in the process of sample pretreatment, the method is simple and rapid, reagents are saved, the cost is low, environmental protection is facilitated, and sensitivity and accuracy both meet the requirements of pesticide residue analysis. The method can be used for performing the sample pretreatment on daily detection and analysis of nine kinds of organic phosphorus pesticide residues of dichlorvos, ethoprophos, phorate, methyl parathion, chlorpyrifos, fenthion, methidathion, triazophos and phosalone in wine, the nine kinds of organic phosphorus pesticide residues after the sample pretreatment are detected by a gas chromatography-mass spectrometry, the detection results are accurate, the interference was small, and high social and economic benefits are achieved.

Description

technical field

[0001] The invention relates to a method for detecting pesticide residues, in particular to a method for detecting organophosphorus pesticide residues in wine. Background technique

[0002] Wine is an industry with special charm in the history of social, economic and cultural development. At present, nearly 90 countries in the world produce wine. Wine is an international beverage rich in nutrition, and its status among commodities is increasing day by day. In recent years, the total output of wine in the world has basically remained at about 27 million tons, and the average annual consumption is about 22 million tons. The market is very active.

[0003] Wine is a beverage fermented from fresh grapes or grape juice, which contains many nutrients, such as amino acids, mineral elements (including trace elements) and vitamins necessary for the human body, as well as sitosterol, polyphenols and other ingredients, so it is not only nutritious Drinking in moderati...
