fresh pineapple for long-term storage. You can prolong the life of your pineapple for as much as 12 months by freezing it. You will need to remove the skin and the core of the pineapple first. Once the skin and core are removed from the pineapple, store it in an airtight container like Tupperware. Leave a small amount of air in the container with the pineapple. If you happen to have a dehydrator, you can prepare and store your pineapple nearly indefinitely! Dehydrating removes the moisture from the pineapple and makes it a bit more like pineapple "chips" but with all the same nutritional value. Use a sharp knife to peel, core and slice your pineapple. Make sure your slices are consistently about 1/2 inch (1.25 cm) thick. Place in your dehydrator according to the manufacturer's recommendation or at 130 degrees Fahrenheit (54 degrees Celsius) until the fruit reaches a leathery state but is not sticky. It may take 12-18 hours to be fully dehydrated. The last possible method to storing your pineapple for an extended period of time is canning. Canning or jarring your pineapple can prolong its life for a year or more, but it is not recommended to store it for longer than a year to be safe. Once again, slice and core your pineapple by cutting off the top and skins. This time, cutting the pineapple into chunks instead of slices may make it easier to can. You will need to boil your pineapple in a "packing" solution to occupy the additional space in the can and keep it moisturized. You can use apple juice, white grape juice or light to medium "canning syrup" you can buy at some specialty grocery stores. After boiling the pineapple in the packing solution, fill your jars, leaving an inch or so of open space at the top. Place the lids on the jars finger tight, then place it (or however many you have) in a pot with water approximately 1-2 inches taller than the top of the jar or can. Boil the jars for 25 minutes for a pint jar, 30 minutes for quarts. After removing them, the air will have been evacuated and the pineapple will be good to store.
Freeze Use a dehydrator to dry pineapple for storage. Can or jar your pineapple.
