Key Points

Develop a rapid point-of-care colorimetric sensing method using DTNB to detect toxic calcium carbide used for artificial ripening on banana peels.
Applied 5,5′-dithiobis-(2-nitrobenzoic acid) (DTNB) as a rapid chemoreceptor for colorimetric signal generation.
Assayed surface residues directly on banana peel samples to detect artificial ripening agents.
Enabled rapid visual colorimetric discrimination of calcium carbide residues on fruit surfaces.
Established an on-site testing framework suitable for low-cost, point-of-care food fraud surveillance.
