How to Store Raisins for a Long Time?

Although raisins are considered good emergency food, they are more difficult to store than other dry foods due to their high moisture content.

Here's what you need to know about the shelf life of raisins and how to store them for a long time.

Because raisins are dry and naturally high in sugar, they generally do not support the growth of bacteria or other microorganisms. However, if stored in a humid place, raisins can absorb moisture from the air and start to mold.

Over time, the nutrients in raisins break down and lose their flavor. Pests such as food moths are also common. They're still safe to eat, but most people don't want to eat insect larvae with raisins.

The key to the long-term storage of raisins is to keep them safe from moisture and pests. To protect the nutrients in raisins, you also need to protect them from light and heat. Here's the best way to do so.

The raisins are further dried first. They will then be safe enough to be stored with oxygen absorbers. Packed like this, raisins should last 10 to 15 years.

Tips:

1. Place the raisins on a clean surface.

2. Use the bottom of a jar or other flat item to crush the raisins. Your goal is to break down the skins, making them more prone to dehydration.

3. Put the raisins in the dehydrator. If you don't have a dehydrator, you can dehydrate them in the oven at a lower temperature.

4. Dehydrate the raisins until completely dry. They should be hard little rocks.

5. Let the dried raisins stay in shape. This includes placing them in an airtight container and allowing the moisture to distribute evenly.

6. Now you can pack them safely in mylar bags with oxygen absorbers.

Airtight jar with a two-piece lid provides an airtight seal. This will protect the raisins from moist air and keep them from getting moldy. Airtight jars are also effective at keeping pests out.

The flavor of raisins may change, but they should be stored this way for a few years. I still recommend checking them occasionally and rotating your supplies thoroughly!

Tips:

1. Put the raisins in a jar.

2. Don't pack them too tightly or moisture pockets will form.

3. Put a desiccant on the raisins.

4. Close the jar.

5. Store it in a cool, dark place that won't break.

Because vacuum sealing removes all oxygen from the container, it's a safe way to store raisins: you don't have to worry about botulism. Raisins should be stored like this for at least 3 years if stored in a cool, dark place.

Generally speaking, vacuum-sealed bags are not a good way to store food for long periods of time. Plus, vacuum-sealed raisins can develop a lot of speckling.

If you don't mind a chunk of raisins, you can go ahead and vacuum seal them. It should at least help extend the shelf life. But you'll also want to place the bag in a food-safe container with a good lid to help keep moisture and pests out.

Raisins will keep indefinitely in the refrigerator. However, raisins can absorb some of the unpleasant odors in the refrigerator and clump together into one giant blob.

There are some ways to prevent this:

Tips:

1. Spread the raisins on a tray and place them in the refrigerator for an hour. This pre-freezing step prevents the raisins from sticking together to form one giant raisin mass.

2. Once the raisins are frozen, remove them from the tray.

3. Double wrap the raisins in a heavy-duty freezer bag. This will prevent the raisins from absorbing odors in the refrigerator.

The above is how to store raisins. If you have any questions or want to buy raisins, please contact us.
