“…A sensor, which consists of an identification component, a conversion component, signal display electronics, and a signal processing unit, generates a signal through the interaction of an identification component with a detection substance, triggering a modification of the identification component (receptor) and then converting it into a useful signal into an electronic instrument for display through a conversion component (Ghaani et al., 2016; Zhang, Guo et al., 2021). In F&V packaging, sensors can respond to characteristic substances released by the metabolism of F&V (e.g., oxygen, carbon dioxide, ethylene, and aldehydes) or to possible endogenous hazards (pesticide residues, toxins, microorganisms, etc.…”
