Scope

Scope: This document is applicable to the rapid detection of carbendazim, benomyl, and thiabendazole in vegetables and fruits such as Shanghai green vegetables, spring vegetables, green beans, cucumbers, apples, pears, grapes, etc.; Main technical content: This document specifies a method for the rapid detection of carbendazim, benomyl, and thiabendazole in fruits and vegetables using Raman spectroscopy. Different substances have characteristic Raman spectra corresponding to their molecular structures. When a nano-enhanced reagent with the Surface Enhanced Raman Scattering (SERS) effect is introduced, the Raman signal of the substance will be significantly enhanced. Take an appropriate amount of crushed samples, extract, purify, and enrich them with solvents, then add the SERS enhancing reagent and conduct Raman spectroscopy scanning. Based on the Raman characteristic spectral peaks of carbendazim, benomyl, and thiabendazole (see Appendix A), the results are determined as follows: the presence of characteristic peaks indicates a positive result, otherwise it is a negative result.
