How To Store Prunes: Shelf Life, Temperature, etc.

Prunes are usually available in a dried form, and most of them did not undergo the drying process and have added preservatives; that’s why they have a good shelf life. Prunes can be used for about 6 to 12 months. If these are stored properly, then they may keep fresh in taste for a long time, as well. To check if they are still fresh, you can check the aroma of prunes before picking them up from the shelf, as it will give you an idea about the quality of the product.

Generally, prunes last 5 – 7 days if kept in the refrigerator. If storing in a fridge, sort out the fruits, throw out all spoiled, then place them in plastic containers or jars. When stored in a freezer, prunes can last from 12 to 18 months. However, prunes may remain safe beyond that time.

So, if there’s a rotten smell in the prunes, then your dried fruit has gone bad for sure. Good thing, there’s a lower chance of mold formation with dried fruit than fresh fruit because the moisture has been removed. However, be still aware of mold and toss your dried fruit, even the slightest mold is visible.

Of course, there are certain health risks associated with spoiled foods so keep practicing food safety and enjoy the foods before their shelf life has expired!

When checking prunes for spoilage, make sure you:

  • Look for any visual signs of deterioration. These include mold, especially near the stem and if the skin is shriveled. The latter doesn’t mean the fruit is spoiled completely, but, you can say the prune is old.
  • Check the firmness of the fruit. If the prunes are super soft and filled with oozing juice, it’s time for them to discard.
  • Check for worms or larvae inside. Make sure to always cut the prunes and remove the pit before eating. This is to ensure that the insides are free of any insects. Eating the whole thing, then spitting out the pit is not a good idea when it comes to prunes.

How To Dry And Store Dried Prunes

If you have an abundance of prunes, it’s a good idea to dry them. Dried prunes are more flavorful to a wide range of dishes. They are also great tasty and healthy snacks. When stored properly, dried prunes can be kept for a long time. Hence, here are some helpful techniques for drying prunes at home.

Drying Prunes In The Oven

Using the oven is a popular, practical, and easy way of drying prunes.

Follow these steps when drying prunes in the oven:

  1. Using a small, easy-to-handle, sharp knife, cut the prunes in half. Workaround the pit. Separate them in halves from each other. Take out and discard the pit. You can cut the prunes into smaller pieces to hasten the drying process.
  2. Arrange the prunes on the oven rack. Allow some space in between each fruit. If the prunes stand too close to each other, it can delay the dehydration process.
  3. Put a piece of foil or a foil-lined baking tray underneath the rack. It is because the prunes release lots of juice as they go through the drying process. If you put the prunes on a baking pan, the juice will stick to the pan, which can affect the drying process. It is wiser to put the prunes directly on the rack.
  4. To avoid such mess, place a single layer of foil on the base of the oven, which serves as a catch basin. Use the baking tray lined with foil and put it underneath the rack.
  5. Set the oven at 175° – 200° Fahrenheit or lower. When drying prunes, it is best when the oven is set at the lowest temperature possible.
  6. If you want the prunes to dry out in an even manner, check them every couple of hours or so then flip them over now and then. This aims to achieve even drying.
  7. If you want your prunes to be slightly dryer, keep them in the oven longer.
  8. Take the prunes out of the oven, once they show the level of dryness that you like.

The drying time will depend on how much juice the prunes have, before putting them in the oven. You must check on them regularly. Typically, drying prunes in the oven may take about eight hours.

Here are the steps on how to do it.

  1. Choose high-quality fresh prunes. Wash the prunes, then slice them in half. Use a small sharp knife to do this. Remove the stem and the pit.
  2. Load the prunes on the trays of the dehydrator. If you have a lot of prunes, it’s alright to load them close to each other on the trays. However, make sure they do not overlap as it can affect the air circulation and slows down the drying time.
  3. After you put the prunes on trays, turn on your dehydrator to begin the drying process. If you have a conventional dehydrator, set the temperature to 115° Fahrenheit.
  4. Drying time will depend on factors like the amount of water in the prunes, the thickness of the fruit, humidity, temperature, and altitude. On average, prunes dry out within 8 to 14 hours in a dehydrator.
  5. Check the prunes every so often. Turn the prunes when the upside is dry. If they cling to the tray, it is still moist; leave it for a few hours more before trying to turn them again.
  6. Take a slice, wait for it to cool, and then check the consistency. If the prune seems dry to your touch, it is done. Keep in mind that they dry at different times, so remove the ones that you think are dry enough for your taste. Check the other sides regularly.
  7. Cool your dried prunes for 30 to 60 minutes. Make sure that they are cool before you store them.
