So it you had a bumper crop of apples, peaches, pears, what have you. The question is what to do with all that surplus? The neighbors and family members have had enough and you’ve canned and frozen all that you can handle. Sounds like it’s time to try drying fruits for long-term storage. Drying fruits and vegetables will allow you to extend the harvest far past the growing season. Read on to find out how to dry fruit at home, as well as vegetables.

Drying Fruit for Long-Term Storage

Drying food removes the moisture from it so bacteria, yeast and mold can’t cultivate and end up spoiling the food. Dried or dehydrated fruit from the garden then becomes much lighter in weight and smaller in size. Dried food can then be rehydrated if desired or eaten as is.

There are a number of ways to dry food. The age old method is drying via the sun, hence the term sun dried fruit, like tomatoes. A more modern approach is with a food dehydrator, which combines warm temps, low humidity and airflow to dry food quickly. The warm temperatures allow the moisture to evaporate, the low humidity pulls moisture rapidly from the food and into the air, and the moving air speeds up the drying process by pulling the moist air away from the food.

How about ovens? Can you dry fruit in the oven? Yes, you can dry fruit in the oven but it’s slower than a food dehydrator because it doesn’t have a fan to circulate air. The exception here is if you have a convection oven, which does have a fan. Oven drying takes about twice as long to dry food than in a dehydrator so it uses more energy and is less efficient.

Prior to Drying Fruits and Vegetables

Begin preparing the fruit for drying by washing it well and drying it. You don’t need to peel fruit before drying it, but the skin of some fruit, like apples and pears, becomes slightly tough when dried. If you think that might bother you, then peel it. Fruit can be cut in half or in thin slices, or even left whole. The larger the piece of fruit, though, the longer it will take to dry. Very thinly sliced fruit like apples or zucchiniwill become crisp like a chip.

Fruits like blueberriesand cranberriesshould be dipped into boiling water to crack the skin. Don’t leave the fruit in too long though or it will become cooked and mushy. Drain the fruit and quickly chill it. Then blot the fruit dry and proceed to drying.

If you’re a purist, you may want to pre-treat some types of fruit. Pre-treating reduces oxidation, results in a nicer color, reduces the loss of vitamins and lengthens the shelf life of the dehydrated fruit from the garden. I’m not particularly concerned about any of that and our dehydrated fruit is so good it never needs to be stored for long; I eat it.

There are a number of ways to pre-treat fruit. One method is to place cut fruit in a solution of 3 ¾ teaspoons of powdered ascorbic acid or ½ teaspoon of powdered citric acid in 2 cups of water for 10 minutes prior to drying. You can also use equal parts of bottled lemon juice and water, or 20 crushed 500mg vitamin C tablets mixed with 2 cups of water in lieu of the above.

Another method for pre-treating fruit is by syrup blanching, which means simmering the cut fruit in a syrup of 1 cup sugar, 1 cup corn syrup and 2 cups water for 10 minutes. Remove the concoction from the heat and allow the fruit to sit in the syrup for an additional 30 minutes before rinsing it and laying it on dryer trays. This method will result in sweeter, stickier, candy-like dried fruit. There are also other methods to pre-treat fruit before drying that can be found in a quick search of the internet.

How to Dry Fruit at Home

There are several ways of drying garden fruits and vegetables:


If using a dehydrator to dry fruit or vegetables, lay the pieces side by side, never overlapping on a drying rack. If you are using a pre-treated fruit, it is wise to lightly spray the rack with vegetable oil; otherwise, it will stick to the screen or tray. Preheat the dehydrator to 145 F. (63 C.).

Put the trays in the preheated dehydrator and leave them for one hour, at which point, reduce the temperature to 135-140 F. (57-60 C.) to finish drying. Drying time will vary depending upon the dehydrator, the thickness of the fruit and its water content.

Oven drying

For oven drying, place the fruit or vegetables on a tray in a single layer. Put them in a preheated oven at 140-150 F. (60-66 C.) for 30 minutes. Open the oven door a bit to allow the excess moisture to escape. After 30 minutes, stir the food around and check to see how it is drying. Drying can take anywhere from 4-8 hours depending upon the thickness of the slices and water content.

Sun drying

For sun dried fruit, a minimum temperature of 86 F. (30 C.) is needed, even higher temps are better. Watch the weather report and pick a time to sun dry fruit when you will have several days of dry, hot, breezy weather. Also, be aware of the humidity level. A humidity of below 60% is ideal for sun drying.

Dry fruit in the sun on trays made of screen or wood. Be sure that the screening is food safe. Look for stainless steel, Teflon coated fiberglass or plastic. Avoid anything made from “hardware cloth,” which can oxidize and leave harmful residue on the fruit. Avoid copper and aluminum screens as well. Don’t use green wood, pine, cedar, oak or redwood for making trays, as they warp. Place the trays on a block to allow for better air circulation atop a concrete driveway or over a sheet of aluminum or tin to foster increased sun reflection.

Cover the trays with cheeseclothto keep the greedy birds and insects off. Cover or bring the drying fruit in at night since the cold condensing air will rehydrate the food and slow down the dehydrating process which will take several days.

Storing Dehydrated Fruit and Vegetables

Fruit is dry when it is still pliable but no beads of moisture form when pressed. Once the fruit has dried, remove it from either the dehydrator or oven and allow it to cool before packaging it for storage.

Dried fruit should be packed loosely into an air tight glass or plastic container. This allows any remaining moisture to distribute evenly among the fruit slices. If condensation forms, the fruit is not sufficiently dried and should be dehydrated further.

Store packaged dehydrated fruit from the garden in a cool, dark area to help it retain the vitamin content of the fruit. Dried fruit can also be stored in the freezer or refrigerator which will help to extend its shelf life…but I don’t expect that to be a problem. Chances are good that your dehydrated fruit will be gobbled up in no time at all.
