Expiration & Storage Tips
When does whole peeled tomato expire?
Whole peeled tomatoes usually come canned and can last up to 18 months unopened, as long as the can is undamaged, securely sealed, and stored in a cool, dry place away from sunlight. Once opened, the tomatoes should be transferred to a non-metallic container, covered, and refrigerated immediately. They will remain in good quality for about 5 to 7 days after opening. As for freezing, you absolutely can freeze whole peeled tomatoes. Once frozen, they're best used within 4 to 6 months.
How do you tell if whole peeled tomato is bad?
Please check for can integrity first as damaged, rusted, bulging or leaking cans may indicate spoilage. Opened tomatoes that have gone bad usually show signs of mold and change in color and smell. If the tomatoes have a sour smell, or are slimy or fizzy upon touch, it's best to dispose of them. Freezing doesn't kill bacteria, so if the tomatoes were bad when they went into the freezer, they'll still be bad coming out.
Tips for storing whole peeled tomato to extend shelf life
• Store unopened cans in a cool, dry, dark place, away from extreme temperature variations.
• Once opened, transfer any unused tomatoes to a non-metallic, airtight container before refrigerating. Try to use up leftovers within a week.
• For freezing, pack the tomatoes in airtight freezer bags or containers. Consider portioning them out before freezing, so you can quickly grab just the amount you need for a recipe.
• Do not freeze cans of tomatoes, as the can may explode. Instead, transfer the tomatoes to a suitable freezer-safe container.
• When thawing frozen tomatoes, avoid a sudden temperature change to retain the integrity of the fruit. A slow overnight thaw in the refrigerator is the best way to do this.
