This application note describes the analysis of fungicides in citrus fruits by high-performance liquid chromatography (HPLC) using detection with both fluorescence (FL) and UV absorption (UV).
In the 1980s, fungicides were introduced as post-harvest pesticides and used for long-term storage of fruits and vegetables. Since the 1990s, imported disposable chopsticks have also become a problem. Even today, fungicides are still approved for use in the safety of imported foods, and residue limits have been established.
In order to analyze fungicides, the separate analysis of Imazaril (IMZ) and simultaneous analysis of three other components, orthophenylphenol (OPP), thiabendazole (TBZ) and diphenyl (DP), were carried out under the Hygiene No.15 Notice Law.
