Shelf life of Key limes is an important consideration in marketing. The lime still ripens for a considerable time after harvesting, and it is usually stored between at a relative humidity of 75–85%. Special procedures are employed to control the shelf life; for example, applications of growth regulators, fruit wax, fungicides, precise cooling, calcium compounds, silver nitrate, and special packing material. The preferred storage conditions are temperatures of and a humidity over 85%, but even in ideal conditions post-harvesting losses are high.
