Pineapple is an amazing food. Pineapple isn’t just tasty, it contains Bromelain, a powerful digestive enzyme that helps break down protein. It’s a good accent or side dish to serve with any protein, including ham and fish. And, pineapple is one of the most popular items to freeze dry. It’s crunchy and delicious, but also healthy because there are no additives or preservatives to keep it tasting great for years to come.

To freeze dry pineapple, cut into pieces that are approximately 3/4″ thick. Then, lay out a single layer of pineapple on your trays. Because pineapple is high in sugar content and has lots of water, and can sometimes take longer to freeze. One thing you can do to help insure you get the best quality of freeze dried pineapple is to set your freeze dryer for 12 hours of freezing time and 12 hours of drying time. At the end of the process, check to make sure your pineapple is nice and crunchy and that there is no moisture or ice nugget in the largest pieces. If there is, simply add a little more dry time. When complete, store your pineapple in an airtight container until you’re ready to eat it.

Freeze dried pineapple has an addictive, intense flavor when eaten as freeze dried chunks. (Add it to trail mix for a new take on an old favorite.) It’s also a great topping for yogurt or oatmeal. You can add freeze dried pineapple to your favorite quick break and muffin recipes. To re-hydrate pineapple for side dishes such as salsa for fish tacos, or to top a baking ham, soak in a bowl of water until it returns to the original consistency. But, freeze dried pineapple is so delicious that you’ll end up eating it as a crunchy snack before you rehydrate it.

Winters don’t have to be wall-to-wall root vegetables and apples. If you’ve got a home freeze dryer, you can enjoy a taste of the tropics all year long.

For most of the United States pineapple is unavailable. I live in Florida, have 126 plants in my garden as we speak. I harvested fifty beautiful ripe fruits this year. There are currently four trays in the freeze dryer. So happy I bought one from your company a few years ago.

Our pineapple keeps sending up shriveled. It tastes good, but isn’t holding shape like yours. It gets totally dry. What should we do? Is it a temperature thing? We’ve even cut thinner slices and still it’s just not working…

Hi Clarissa, pineapple is one of the most difficult fruits to freeze dry due to is cellular structure and the high sugar content. If a pineapple is too ripe, it will almost always shrivel. Also, we like to pre-freeze our pineapple before putting it in the freeze dryer. This helps as well.

We have tried three rounds of pineapple, precut and prefrozen and it is not drying properly! We had one tray in with 3 trays of other foods and even after 30 hours it was still wet and tacky while everything else was beyond done.

Pineapple is one of the toughest foods to freeze dry. It often takes longer than 36 hours because of its cellular structure and sugar content.

I have tried freeze drying drained canned pineapple. I gave it extra drying time. I also made sweet and sour pork with pineapple also with extra dry time. I found the little pieces were slightly chewy and ended up putting the pork dish in a mylar bag in the freezer and splitting the dried pineapple into small mylar bags with oxygen inhibitors but I think I will end up having to use it quite soon. Any ideas?
