Technical specification

What is the difference between pitted and unpitted prunes?

Choosing between the two formats is a question of sales channel rather than preference. They differ in processing, moisture, quality classes and where the goods are used downstream.

Two prune packaging formats side by side

Direct answer

Which format should you choose?

Unpitted prunes undergo less processing and are sought on markets with traditional consumption. Pitted prunes are mechanically stoned and usually rehydrated, which makes them more practical for retail and industrial processing. Under the UNECE standard, whole prunes have one quality class while pitted prunes have two.

Decision data

The two formats compared

Pitting is an additional operation with its own loss, so it affects both price and shelf life. In return it delivers a product ready for use without further handling by the buyer.

Direct answer

Which format does each channel require?

Retail and foodservice mostly ask for pitted prunes because they are simpler to use and to label. Industrial processing selects by technology: fillings and pastes take pitted fruit, while some traditional markets still require the whole fruit.
