Canned pineapple is so much easier than carving a fresh pineapple, but depending on the size of your can, it can often be more than you can eat or prepare in a single sitting.
Once the can has been opened, can you freeze canned pineapple? Yes, you can freeze canned pineapple for up to 2 months in an airtight container, but never freeze it unopened in the original can.
In this article, we’ll discuss everything you need to know about storing and preserving the life of your canned pineapple.
Does Canned Pineapple Go Bad?
Storebought canned goods will always have a “use before” or “best before” date stamped on the can and we always recommend following these instructions.
If the pineapple is canned properly, it will stay safe more or less indefinitely.
If your pineapple is in a metal can there is some concern that chemicals, toxins, or actual metal can eventually leach into your food over time. You won’t taste that, however, and your pineapple will taste fine forever.
If you do your own canning, as long as the seal works perfectly and doesn’t accidentally pop during storage, your pineapple will also last indefinitely.
Once it’s opened, however, your pineapple will absolutely go bad in time. If it’s properly refrigerated, it should last safely for up to 1 week. If you freeze it carefully, you can extend the life up to 2 months.
How to Tell if Canned Pineapple Is Bad
The most obvious sign of pineapple that has gone off is the development of mold. It may be either green or white, depending on what bacteria have grown, but both are bad signs and you should discard the pineapple immediately.
If your pineapple has a sour smell, or if the aroma or flavor is significantly different from when the can was first opened, those are also signs that it is starting to turn bad. It probably won’t hurt you, but it can cause indigestion.
How to Freeze Canned Pineapple
You can freeze canned pineapple either in the juice from the can or drained.
How to Freeze Canned Pineapple in the Juice
If you’re freezing pineapple with the juice, follow these steps:
- Transfer the pineapple and the juice to a freezer-safe Tupperware container.
- Make sure there is at least 1” of space at the surface to allow the pineapple to expand during freezing.
- Seal the container, making sure it is airtight.
- Label your container with the date so you can be sure to use it within 2 months.
- Freeze in the main compartment of your freezer, as far away from the door as possible.
If you’re going to drain your pineapple before freezing, you will also want to rinse it under cold water to remove as much of the sugar as possible to get a clean freeze.
How to Freeze Rinsed Canned Pineapple
Once your pineapple pieces are rinsed, tap them dry with a paper towel as best as you can and follow these steps:
- Cover a baking sheet with parchment paper.
- Spread your pineapple out over the tray in a single layer so none of the pieces are touching or overlapping.
- Freeze for 1–2 hours.
- When thoroughly frozen, transfer the pineapple pieces to a freezer-safe Ziploc bag and seal carefully.
- Date the bag and use your pineapple within 2 months.
Can You Freeze Crushed Pineapple?
Yes, you can also freeze crushed pineapple. The best way to do so is to first separate it into individual portion sizes, depending on what you plan on using it for in the future.
Once separated, follow these easy steps:
- Prepare a freezer-safe Ziploc bag by writing the date on the bag.
- Transfer your portion size of crushed pineapple to the Ziploc bag.
- Lay the bag flat on the counter and spread the pineapple out so that the bag is flat, with no air bubbles or bulges.
- Place the flat bag on a baking tray and freeze like this for 1–2 hours.
- Once completely frozen solid you can remove the baking tray and stand the Ziploc bag upright in your freezer to save space.
Use your crushed pineapple within 2 months of freezing, just like the other forms of pineapple.
Alternative Pineapple Storage
If you’re not planning on freezing your canned pineapple you still want to be sure you store it safely after the can has been opened.
The best solution is to transfer the pineapple in its juice to a Tupperware container with an airtight seal. You can use a Ziploc bag but there’s a higher risk of it being squished or the seal opening up and making a pineapple mess in your fridge.
When you want to use your pineapple, take a portion out of the container. Don’t eat directly from the container and then put it back in the fridge as this is how bacteria and other unfriendly visitors will get into the container and spoil your pineapple.
Pineapple that is stored in the fridge should be eaten within 1 week of being opened.
