Chilling injury (CI) causes significant losses in fruits and vegetables during cold storage. CI symptoms exhibited as browning, off-flavour and sunken spots, reduced juice content, uneven ripening and softening in fresh horticultural produce. Application of melatonin (MT) effectively mitigates CI in cold-stored fruits and vegetables. This comprehensive review focuses at discussing symptoms, the mechanism of CI, regulation of melatonin-mediated chilling tolerance, and meta-analysis of CI reduction in horticultural produce. Melatonin mitigates CI, maintains quality of cold-stored horticultural produce by upregulating early hydrogen peroxide signalling, activities of antioxidant enzymes after inhibition of reactive oxygen species (ROS) accumulation, mitochondrial dysfunction, and membrane leakage.
