Can unopened canned tomato paste go bad?
Canned tomato paste has a long shelf life when unopened, but it can eventually go bad. Typically, an unopened can of tomato paste is safe to consume for at least 18 months to two years past its “best by” date, assuming it has been stored properly in a cool, dry place. Signs that the tomato paste may have gone bad include an off odor, mold growth, or if the can is bulging or rusted. Before use, always check the date and the condition of the can to ensure the product is safe to consume. To extend its shelf life even further, you can transfer the contents into an airtight container and store it in the refrigerator once opened. Unopened canned tomato paste is quite stable, but vigilance in checking its condition is still important for safety and quality.
How can I tell if my canned tomato paste has gone bad?
Determining whether your canned tomato paste has gone bad involves several key observations. First, check the expiration date on the can; any paste past its expiration date should be discarded. Next, examine the can for any signs of dents, bulges, or leaks, as these can indicate spoilage or contamination. Open the can in a well-ventilated area and smell the contents; a sour or off-putting odor is a clear sign of spoilage. Additionally, if the paste has changed color significantly or has mold growing on it, it should be thrown away. Lastly, the texture should be smooth and consistent; if it feels slimy or grainy, it’s best not to use it. By following these steps, you can ensure that the canned tomato paste you use in your cooking is fresh and safe.

If you find yourself with an expired can of tomato paste, check for any off smells, mold, or an altered texture before using it.
