Pineapple is one of the most popular tropical fruits in the world. It has a sweet, tangy taste that goes well with its juicy texture. The tropical flavor with a hint of citrus is so distinct it mixes perfectly on both sweet and savory dishes. Unfortunately, it’s also highly perishable, so you can’t hoard it to your heart’s content even if it’s on sale.
But what if you could preserve pineapple for years without losing its flavor, nutrition, or appearance? That’s where freeze drying comes in. Freeze drying is a method of dehydration that removes the water content of a product by turning it from ice to vapor, without going through the liquid state. This process preserves the product’s shape, color, taste, and nutrients better than any other method of preservation.

How to Freeze Dry Pineapple at Home
To freeze dry pineapple at home, you will need a freeze dryer machine. A freeze dryer machine is an electric appliance that removes 98% of moisture from food by turning it from ice to vapor. This process takes several hours and requires specific settings for different types of food.
There are only a few options for home use freeze dryer machines on the market, and they are not cheap. However, they can be a worthwhile investment if you want to preserve your own food for emergencies, camping, or culinary experiments. Some of the best freeze dryer machines for home use are :
- Harvest Right Medium Home Freeze Dryer: This is one of the most popular and versatile models. It can freeze dry up to 15 pounds of food per batch and up to 3000 pounds of food per year. It has a smart technology that automatically adjusts the temperature and pressure for optimal results. It also has a touch screen display that shows the progress of each cycle. It costs around $3,000.
- Harvest Right Small Home Freeze Dryer: This is a smaller and cheaper version of the medium model. It can freeze dry up to 10 pounds of food per batch and up to 1800 pounds of food per year. It has the same smart technology and touch screen display as the medium model. It costs around $2,500.
- Harvest Right Scientific Freeze Dryer: This is a more advanced and expensive model that is designed for scientific and pharmaceutical purposes. It can freeze dry up to 18 pounds of food per batch and up to 5000 pounds of food per year. It has a larger chamber and more precise controls than the other models. It also has a vacuum pump that does not require oil changes. It costs around $7,000.
Once you have your freeze dryer machine ready, you can follow these steps to freeze dry pineapple at home:
Step 1: Choose Your Pineapple
You can use fresh or canned pineapple for freeze drying, but fresh is better for flavor and texture. You can choose any variety of pineapple, but some are more suitable than others. The best varieties for freeze drying are:
- Smooth Cayenne: This is the most common variety found in supermarkets. It has a sweet, juicy flesh and a yellow skin with brown eyes.
- Queen: This is a smaller variety that has a rich sugar content and an intense pineapple flavor. It has a golden skin with fewer eyes than Smooth Cayenne.
- Abacaxi: This is a large variety that has a sweet, acidic flesh and a yellow-green skin with prominent eyes.
- Pernambuco: This is a small variety that has a very sweet flesh and a yellow skin with small eyes.
- Kona Sugarloaf: This is a white-fleshed variety that has a mild flavor and low acidity. It has a green skin with few eyes.
- Red Spanish: This is a yellow-fleshed variety that has a firm texture and a pineapple-apple flavor. It has a red skin with many eyes.
You should choose a pineapple that is between just ripe and fully ripe. A ripe pineapple has a yellow skin, a sweet aroma, and a slight give when pressed. A fully ripe pineapple has a brown skin, a strong aroma, and a soft texture. A ripe pineapple will have more flavor and less water than a fully ripe one, which will make it easier to freeze dry.
Step 2: Prepare Your Pineapple
You need to peel, core, and slice your pineapple before freeze drying it. You can use a knife or a special tool to do this. Here are the steps to prepare your pineapple:
- Cut off the top and bottom of the pineapple.
- Stand the pineapple upright and cut away the skin as thinly as possible, following the curve of the fruit.
- Remove any remaining eyes by cutting them out in a spiral pattern, angling your knife slightly.
- Cut the pineapple in half from top to bottom, then cut each half into quarters.
- Cut out the core from each quarter by slicing off about half an inch of the inner edge.
- Cut each quarter into slices or chunks of about 3/4 inch thick.
Step 3: Pre-Freeze Your Pineapple
You need to pre-freeze your pineapple before putting it in the freeze dryer machine. This will help speed up the freeze drying process and prevent the pineapple from melting during the cycle. To pre-freeze your pineapple, follow these steps:
- Arrange the pineapple slices or chunks in a single layer on a baking sheet lined with parchment paper or silicone mat. Leave some space between them to allow air circulation.
- Place the baking sheet in the freezer for at least 4 hours or until completely frozen.
- Transfer the frozen pineapple to a ziplock bag or an airtight container and store in the freezer until ready to use.
Step 4: Freeze Dry Your Pineapple
You need to set your freeze dryer machine to the appropriate settings for pineapple. The settings may vary depending on the model and size of your machine, but here are some general guidelines:
- Set the freeze time to 12 hours. This is the time it takes for the machine to freeze the food to -40°F (-40°C).
- Set the dry time to 24 hours. This is the time it takes for the machine to remove the water from the food by turning it from ice to vapor.
- Set the final dry time to 6 hours. This is the extra time it takes for the machine to remove any remaining moisture from the food.
To freeze dry your pineapple, follow these steps:
- Load the frozen pineapple slices or chunks onto the trays of your freeze dryer machine. Make sure they are not touching each other or overlapping.
- Place the trays inside the chamber of your freeze dryer machine and close the door securely.
- Turn on your freeze dryer machine and start the cycle. The machine will automatically adjust the temperature and pressure according to your settings.
- Monitor the progress of your cycle on the touch screen display of your machine. You can also check on your food through the window of your chamber.
- Wait until your cycle is complete. The machine will beep when it is done.
Step 5: Store Your Freeze-Dried Pineapple
You need to store your freeze-dried pineapple in airtight containers away from light and moisture. This will prevent oxidation, mold growth, and insect infestation that can spoil your food. You can use glass jars, plastic containers, mylar bags, or vacuum sealers for this purpose.
To store your freeze-dried pineapple, follow these steps:
- Remove the trays from your freeze dryer machine and let them cool down for about 10 minutes.
- Transfer your freeze-dried pineapple slices or chunks to your chosen containers. Leave some headspace for expansion if using glass jars or plastic containers.
- Seal your containers tightly and label them with the date and contents.
- Store your containers in a cool, dark, and dry place away from heat sources and direct sunlight.
