Curing is an essential postharvest process for root and tuber crops. It allows damaged surfaces to heal by forming a new layer of protective tissue beneath the wounds, while thickening the outer skin. This healing process repairs minor cuts and scrapes from harvesting, reduces moisture loss during storage, and blocks out spoilage-causing micro-organisms.
