What is the shelf life of unopened tomato paste?

Unopened canned tomato paste typically has a shelf life of 18-24 months from the date of production, provided it is stored in a cool, dry place. Some brands may have a slightly shorter or longer shelf life, so it is always best to check the "best before" or "expiration" date printed on the can.

Once opened, tomato paste can be stored in the refrigerator in an airtight container for up to 5-7 days. For longer storage, it can be frozen in airtight containers or ice cube trays for up to 3-6 months.
