Canned tomatoes can be stored in the freezer for an extended period, but it's essential to follow proper guidelines to ensure their quality and safety. Generally, canned goods are safe to eat for an extended period as long as the cans remain intact and undamaged. The primary concern when freezing canned tomatoes is related to their packaging.
When transferring canned tomatoes to the freezer, it is recommended to remove them from the can and place them in a freezer-safe container or airtight freezer bags. This helps prevent potential issues with can integrity, such as the expansion of liquids when frozen, which could cause the can to burst.
In the freezer, properly stored canned tomatoes can last for up to 12 to 18 months without significant loss of quality. However, it's important to note that while the tomatoes themselves may still be safe to eat after this time, the taste and texture may deteriorate over extended periods.
To maintain the best quality, try to use the frozen tomatoes within the first year of freezing. Before using them in recipes, thaw the tomatoes in the refrigerator or under cold running water, and avoid refreezing them once they have been thawed.
Always inspect the tomatoes before using them to ensure there are no signs of spoilage or off-odors. If you notice any unusual or suspicious characteristics, discard them immediately.
Remember that freezing doesn't improve the quality of canned tomatoes; it merely helps preserve them. If you have canned tomatoes that are nearing their expiration date, consider using them in recipes before resorting to freezing to avoid any potential waste.
