- How long does frozen pineapple last? The precise answer to that question depends to a large extent on storage conditions - keep pineapple frozen at all times.
Properly stored, frozen pineapple will maintain best quality for about 12 months in the freezer, although it will usually remain safe to eat after that.
Is frozen pineapple safe to eat after the expiration date on the package? Yes, if properly stored - commercially frozen pineapple will typically carry a “Best By," "Best if Used By," “Best Before”, or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the frozen pineapple will remain at peak quality.
How long will frozen pineapple remain safe to eat? Frozen pineapple that has been kept constantly frozen at 0°F will keep safe indefinitely, as long as it has been stored properly and the package is not damaged.
How to tell if frozen pineapple is no longer good? If dry spots or discoloration have developed on the frozen pineapple, freezer burn has begun to set in - this will not make the pineapple unsafe to eat, but it will harm the texture and taste.
