The sooner a fresh fig reaches 0 °C after harvest, the longer it lasts. The UC Davis Postharvest Center and USDA Agriculture Handbook 66 recommend -1 to 0 °C, 90-95% relative humidity and expedited forced-air cooling to 0 °C. Under those conditions Black Mission and Calimyrna figs keep for 1-2 weeks, depending on cultivar and ripeness at harvest.
| Item | Value |
|---|---|
| Storage | -1 to 0 °C, 90-95% RH |
| Retail display | 0-2 °C, 90-95% RH |
| Respiration at 0 °C and 20 °C | 2-4 and 20-30 ml CO2/kg·h |
| Ethylene | Slightly sensitive; softening and decay increase at 5 °C and above |
| Chilling injury | Not chilling sensitive |
At 20 °C a fig respires roughly eight times faster than at 0 °C, taking mid-range values, so a crate waiting in the orchard shade is spending shelf life before it ever reaches the cold room. That is why figs are picked in the cool of the morning and each full tray goes into pre-cooling without waiting.
A ripe fig is soft and bruises easily; the USDA handbook notes that figs are hand-picked and packed in a one-layer box. A second layer would crush the fruit below, so transport uses single-layer trays shelved one above another rather than a deep box. Every transfer means more bruising and more warming, so where possible the tray filled in the orchard stays the same tray all the way to the shelf.
A closed insulated container keeps the fruit's own moisture in, while dry air in an open crate shrivels the skin. If eutectic plates are used, a shelf or separator sits between fruit and plate, because a fig touching a sub-zero surface freezes.
