Storage and handling

How should prunes be stored?

Prunes are a stable product, but their texture and shelf life depend on storage conditions. The same goods can lose quality before the printed date if held warm or damp.

Sealed packs of prunes

Direct answer

Where and how are prunes stored?

Prunes keep best in a cool, dry and dark place in well sealed packaging. An opened pack is best kept in an airtight container, and in warm months in the refrigerator. A damp, warm space accelerates spoilage regardless of the declared shelf life.

Decision data

Storage conditions and their effect

The declared shelf life assumes the prescribed conditions. If goods are held outside them, that date stops being meaningful, which matters most when storing larger volumes.

ConditionRecommendationWhat happens otherwise
TemperatureCool and steadyHeat dries the fruit and accelerates darkening
Air humidityDryMoisture softens the fruit and opens the way to spoilage

PackagingSealed, barrier materialOpen packaging exchanges moisture with the air

Direct answer

Does a white coating mean the prunes have spoiled?

Not necessarily. Dried fruit sometimes develops a whitish surface layer formed when sugar migrates out of the fruit and crystallises. It follows a change in temperature or humidity and is not a sign of spoilage. Mould, by contrast, is recognised by its fuzzy structure and smell, and such product is not used.

Reference values

For larger volumes and warehousing

For pallet quantities, storage conditions are agreed in advance, because they determine whether the declared shelf life can be held all the way to the end customer.

Shelf life and storage conditions for a specific batch are stated in the specification accompanying a quotation. General shelf life figures by product type are on the moisture and shelf life page.
