T/SQIA 005-2022 Rapid Detection of Triazole in Vegetables and Fruits by Colloidal Gold Immunochromatography
T/SQIA 005-2022
Basic Information
Scope
Main technical content: This document specifies a rapid detection method for triazoxide residues in vegetables and fruits using colloidal gold immunoassay. This document is applicable to the rapid screening test for triazoxide residues in vegetables and fruits. Note 1: Vegetables include solanaceous vegetables. Note 2: Fruits include citrus fruits, oranges, apples, dates (fresh), bananas, and pineapples. This method uses the principle of competitive inhibition immunoassay. After extraction, triazoxide in the sample binds to the specific antibody labeled with colloidal gold, inhibiting the binding of the antibody and the antigen on the detection line (T line) of the test strip, resulting in a change in the color of the detection line (T line). By comparing the color of the detection line (T line) with that of the control line (C line), a qualitative analysis of triazoxide in the sample can be conducted.
