T/ARAA 001-2024 The rapid detection method for carbofuran in fruits using colloidal gold immunochromatography method

Scope

Main technical content: According to GB 2763-2021 "National Food Safety Standard - Maximum Residue Limits of Pesticides in Food", the maximum residue limits of pesticides in fruits, including citrus fruits, pome fruits, stone fruits, berries and other small fruits, tropical and subtropical fruits, and melons and fruits, are 0.02mg/kg. The detection method: Fruits are detected in accordance with the methods specified in GB 23200.112 and NY/T761. This method uses the principle of competitive inhibition immunoassay. The carbofuran in the sample binds with the specific antibody against carbofuran labeled with colloidal gold, inhibiting the binding of the antibody and the carbofuran antigen on the detection line (T line) in the detection card, resulting in a change in the color depth of the detection line. By comparing the color depth of the detection line with that of the control line (C line), the target carbofuran in the sample can be qualitatively determined.
