The changes of thiophanate-methyl and carbendazim during tomato processing were investigated.
Peeling process removed most of thiophanate-methyl and carbendazim residues.
The PFs on thiophanate-methyl and carbendazim were confirmed in tomatoes during home canning.
The UPLC-MS/MS was used to determine thiophanate-methyl and carbendazim residues.
