Which Foods are More Prone to Over Dehydration?

over dehydrate food

There are certain foods that are more prone to dehydration because of the high temperature used to dry these. Here are some of these foods that you should be careful while dehydrating.

  • Jerky Meat needs to be cooked and then dried because there are microbes and bacteria present in meat that need to be destroyed before the meat is put in the dehydrator. Jerky usually takes 4-6 hours for jerky to dry, but this time can also depend on how you slice your jerky pieces. Thinner pieces will take less time to dry, while thicker pieces will take longer to dry.
  • Vegetables Vegetables are often over dehydrated because looking at the outside of the vegetables, it’s difficult to tell if these are properly dried. The best approach would be to take a slice or two and try to break it, if it’s brittle and breaks easily, it means the vegetables are dried properly and you need to take them out and let them cool.
  • Fruits Fruits have higher sugar content and these can often take a lot of time to dry up properly. The ideal way to dry fruits is to keep an eye on the progress of dehydration and do a taste and snap test every few hours to see how much the food has dehydrated.
  • Nuts If you’re drying nuts and seeds, you need to keep in mind that these are already small in size so judging the progress of dehydration by looking at the size is often not a possibility. You will need to take a piece out of the dehydrator every few hours and check if it is properly dry.

    If you are using food dehydrator with timer then it will turnoff your dehydrator automatically. If not, then you have to turn off dehydrator manually. You can use the alarm to get noticed.
