Over Drying in Dehydrator – The Rule of Thumb

Often, beginners ask: can you over-dry anything in the dehydrator? Firstly, we need to establish that, generally, you cannot over-dry food items in a dehydrator, particularly when prepping them for long-term storage.

In fact, the drier the better. It’s essential for most of the moisture to be removed from the food to ensure safer, more extended storage.

Take for instance, if you left some vegetables drying overnight and they’re still drying the next morning, that’s perfectly okay. This is primarily because you want your food to be as dry as possible, especially when prepping for long-term storage.

The Importance of Dryness for Long-Term Storage

When preparing food for long-term storage, the main aim is to remove as much moisture as possible. This is because the absence of moisture contributes to safer storage. Therefore, the dryer you get your vegetables, fruits, and other food items, the better their quality during storage.

Fruits and Over-drying

For most fruits, it’s also ideal to have them as dry as possible when prepping for storage. However, when it comes to fruit leathers and some snacks, over-drying can result in a texture change, which may not be to your liking.

For instance, fruit leathers that have turned too brittle have been over-dried. Ideally, they should retain some flexibility and have a leathery, dry texture, not crumble apart when handled.

Moreover, it can be easily ground into a powder and used in a myriad of ways. Recently, I’ve enjoyed making flavored rice krispie treats using fruit powders — a delightful twist to a classic snack.

When Over-drying Becomes an Issue

There are exceptions to the rule where over-drying can lead to less desirable outcomes. Take beef jerky, for example. If over-dried, it can become too hard and challenging to eat. So, while over-drying is generally not an issue for long-term storage, it can negatively impact the texture of some foods.

Solving Over-Drying Issues

What happens when you’ve dried something too much and it becomes unpalatably hard? Don’t worry, all is not lost. There are several ways to salvage over-dried food items.

If your fruit leathers or beef jerky are too hard for your liking, you can put them in a ziploc bag with a barely damp paper towel. Let it sit for a while, and the food will begin to reabsorb some of the moisture, making it more pliable for your enjoyment.

Utilizing Over Dried Food

Instead of tossing over-dried food, consider turning them into powders. Over-dried fruit leathers, for instance, can be turned into fruit powders.

These powders can then be used in multiple ways, such as flavoring rice krispie treats or any other dish of your choice. This ensures that none of your produce goes to waste.
