How to Dehydrate Pineapple

Here are 8 tips on How to Dehydrate Pineapple:

  • Prepare the Pineapple
  • Remove the Core
  • Slice the Pineapple
  • Optional Pretreatment
  • Load the Dehydrator

Prepare the Pineapple

To prepare pineapple for dehydration, start by washing and peeling a ripe pineapple. Remove the core and slice it into uniform 1/4 to 1/2-inch thick pieces. Optionally, soak the slices briefly in a lemon juice and water mixture to prevent browning.

Arrange the slices on dehydrator trays and set the dehydrator to 125-135°F (52-57°C). Dehydrate for 8-12 hours, checking for the desired texture. Once dried, cool the pineapple and store it in an airtight container. Enjoy as a nutritious and tasty snack or add it to various dishes. It’s the first tip on How to Dehydrate Pineapple.

Remove the Core

To remove the core from a fresh pineapple, follow these steps:

  1. After washing and peeling the pineapple, stand it upright on a cutting board.
  2. Using a sharp knife, slice off the top and bottom of the pineapple to create a stable base.
  3. With the pineapple standing upright, cut vertically along the sides to remove the skin, ensuring you remove any remaining “eyes.”
  4. Once the skin is removed, you’ll notice the core running down the center of the pineapple.
  5. To remove the core, either use a pineapple corer, which is a tool designed specifically for this purpose, or cut it out by making a cylindrical incision around the core.
  6. After removing the core, you can proceed to slice the pineapple into your desired shapes for dehydrating. It’s the secong tip on How to Dehydrate Pineapple.

Slice the Pineapple

To slice the prepared pineapple for dehydration:

  1. Take the peeled and cored pineapple.
  2. Lay it on a cutting board.
  3. Using a sharp knife, slice the pineapple into uniform pieces. You can choose to cut it into rings or strips, based on your preference.
  4. Aim for a consistent thickness of about 1/4 to 1/2 inch. Thinner slices will dehydrate more quickly, while thicker slices may take longer.
  5. Ensure that the slices are evenly cut to promote even drying.
  6. Arrange the pineapple slices on the dehydrator trays, ensuring they are not overlapping to allow proper air circulation for even dehydration.

Now you’re ready to start the dehydration process. It’s the third tip on How to Dehydrate Pineapple.

Optional Pretreatment

For optional pretreatment to prevent browning during pineapple dehydration:

  1. After slicing the pineapple, prepare a solution of 1 tablespoon of lemon juice per cup of water. This helps preserve the pineapple’s natural color.
  2. Submerge the pineapple slices in this lemon juice and water mixture for a few minutes, ensuring that all the slices are coated. The acid in the lemon juice helps to inhibit oxidation, which causes browning.
  3. Drain the pineapple slices after soaking and arrange them on the dehydrator trays.

Pretreatment with lemon juice is especially useful if you want to maintain the visual appeal of the dried pineapple. However, it’s entirely optional, and you can skip this step if you don’t mind some browning, as it won’t affect the taste or safety of the dried fruit. It’s the fourth tip on How to Dehydrate Pineapple.

Load the Dehydrator

To load the dehydrator with pineapple slices:

  1. Place the prepared and optionally pretreated pineapple slices on the dehydrator trays or fruit leather sheets. Ensure the slices are spread out evenly and not overlapping to allow proper air circulation during drying.
  2. Be mindful of your dehydrator’s capacity and the recommended spacing provided in the dehydrator’s user manual.
  3. Stack the trays in the dehydrator unit. If your dehydrator has adjustable temperature settings, set it to approximately 125-135°F (52-57°C), which is suitable for most fruits, including pineapple.
  4. Close the dehydrator and start the drying process. The time it takes for the pineapple to dry will vary based on your dehydrator’s efficiency, the thickness of the slices, and your desired level of dryness.

Now you can begin the dehydration process to transform your fresh pineapple into delicious dried snacks. It’s the fifth on How to Dehydrate Pineapple.

Dehydrate the Pineapple

To dehydrate the loaded pineapple in your dehydrator:

  1. Set the dehydrator temperature to around 125-135°F (52-57°C), which is the optimal range for most fruits like pineapple.
  2. Begin the drying process by turning on the dehydrator.
  3. Dehydrate the pineapple slices for approximately 8 to 12 hours. The exact time may vary based on factors like the thickness of the slices, humidity, and your desired texture.
  4. Check the pineapple periodically during drying. It’s done when it’s leathery and slightly pliable, no longer sticky or wet, but not brittle.
  5. Allow the dehydrated pineapple to cool completely before removing it from the dehydrator trays.

Your homemade dried pineapple is now ready to be enjoyed as a nutritious and tasty snack or used in various recipes.

Check for Doneness

To check if your dehydrated pineapple is done:

  1. Remove a few representative pineapple slices from the dehydrator.
  2. Let them cool to room temperature.
  3. Gently touch the slices. They should be leathery and slightly pliable but no longer sticky or wet. They should not feel brittle or overly crisp.
  4. Bend a slice; it should flex without breaking.
  5. If you see moisture beads when you squeeze the pineapple, or if it’s still too soft and pliable, return the slices to the dehydrator for more time.
  6. Once the desired texture is achieved, let all the dehydrated pineapple cool completely. If they’re uniformly done, you can remove all the slices.

Properly dehydrated pineapple should have a pleasant chewiness and maintain its flavor and nutritional value.

Cool and Store

After dehydrating your pineapple to the desired texture, follow these steps to cool and store it:

  1. Allow the dehydrated pineapple slices to cool completely. This can take up to an hour to ensure they reach room temperature.
  2. Once cooled, transfer the pineapple slices to an airtight container, such as a glass jar or airtight plastic bag. Ensure there is minimal air inside the container to prevent moisture from reabsorbing.
  3. Store the container in a cool, dark place to maintain the quality of the dried pineapple. A pantry or cupboard works well.
  4. Check the container for any signs of condensation or moisture; if you notice any, return the pineapple to the dehydrator.

Properly stored, dehydrated pineapple can last for several months, providing a tasty and nutritious snack or ingredient for various recipes.


In conclusion, dehydrating pineapple is a simple yet rewarding process that yields a delightful, shelf-stable snack and versatile ingredient for your culinary adventures. Whether you’re craving a naturally sweet treat or looking to elevate your recipes, dehydrated pineapple offers a burst of tropical flavor.

With the right equipment, preparation, and a touch of creativity, you can savor the taste of sunshine year-round. So, seize the opportunity to embark on this homemade dehydration journey, and discover the convenience and deliciousness of your very own dehydrated pineapple. Happy snacking and cooking!
