Problems solved by technology

Therefore, once developed countries initiate trade barriers, if there are no effective countermeasures, it will seriously affect the import and export business of bee products
At present, there is no limit standard for cyantraniliprole in my country, and there are few literature reports on detection methods. At present, there are only reports on the detection method of cyantraniliprole in cowpea, but no report on the detection technology of cyantraniliprole in peak honey. Due to the There is a large gap with the matrix components of honey, and the detection method of cyantraniliprole in cowpea cannot be directly used for the detection of cyantraniliprole in peak honey. Therefore, it is urgent to develop a simple and rapid detection method for cyantraniliprole in honey

Embodiment 1

[0053] Embodiment 1: sample to be tested---honey

[0054] 1.1 Sample preparation: Take 500g representative sample, mix it with a homogenizer, put it into a clean container, seal it and mark it, as a sample. The sample preparation process must prevent the sample from being polluted or changing the residue content, and the sample is stored in a -18°C refrigerator.

[0055]1.2 Background test: each weigh 5.00g (accurate to 0.01g) of the sample in 1.1 in six 50mL plugged centrifuge tubes, then follow step (2), step (3) and step in the present invention successively (4) carry out operation, and each actual measured value and the average value of finally calculating gained are as shown in table 3, and this average value is the background value.

Abstract

The invention provides a detection method for cyantraniliprole in honey. The detection method comprises the steps of preparing a sample; extracting the sample; purifying the sample; and performing analysis detection on a to-be-detected liquid with an ultrahigh performance liquid chromatography-tandem mass spectrometry method, and performing calculation by substituting a certain proportion of a component obtained by ultrahigh performance liquid chromatography-tandem mass spectrometry detection and a peak area of cyantraniliprole into a formula as shown in the specification to obtain a measured value of cyantraniliprole in the to-be-detected liquid. According to the detection method, the blank of a detection technology for cyantraniliprole in the honey in China is filled up; and the detection method has the advantages of easiness for operation and high detection accuracy.

Description

technical field [0001] The invention specifically relates to a detection method for cyantraniliprole in honey. Background technique [0002] Honey is favored by more and more people because of its rich nutritional value and excellent health effects. my country is a big country in honey production, sales and export. With the growing prosperity of the bee product market, the quality and safety of bee products have gradually become prominent. Cyantraniliprole (cyantraniliprole) is a second-generation insecticide with a new o-carboxamidobenzamide structure developed by DuPont, which was officially launched in 2012. The biggest feature of this type of insecticide is that it only acts on the ryanodine (muscle) receptor (RyR) present in the insect body, and has excellent control effects on almost all important Lepidoptera pests. At present, this type of pesticide has been registered for use in the United States, Canada, Australia, the Philippines, Indonesia and other countries. ...
