A colorimetric sensor for detecting an analyte, wherein the analyte comprises an amine, the sensor comprising genipin, a genipin derivative, a salt thereof, hydrate thereof, solvate thereof, tautomer thereof, optical isomer thereof, or a combination thereof. The colorimetric sensor reacts with the analyte to produce a visually discernible color change. A container, a system, and/or a device may comprise the colorimetric sensor. The sensor may be used for detecting the presence of the amine, for example, in spoiled food products. |
