Commercially canned pineapple in all forms, including crushed, chunks or rings, can be frozen for up to two months when stored at 0 F. Never freeze canned pineapple directly in the original can because it could rust or burst open and spoil.
To freeze pineapple chunks and rings, lay the pieces out separately on a baking sheet lined with wax paper, and freeze for one hour before transferring them to an airtight, freezer-safe container. Crushed pineapple can be frozen as is, in a freezer-safe container. It can also be made into cubes for slushies, shakes or sauces by pre-freezing it in ice cube trays before transferring the cubes to the freezer container.
