Tomato Paste Expiration

Tomato paste expiration plays a crucial role in ensuring the quality and safety of this popular cooking ingredient. Typically, once you open a can of tomato paste, it remains fresh for about 5 to 7 days if stored properly in the refrigerator with a tight seal. On the other hand, tomato paste packaged in tubs can last significantly longer—sometimes up to 45 days after opening—making them a convenient option for those who use tomato paste frequently. However, the longer shelf life of tubs often comes at a higher price. Understanding the expiration timeline can help you choose the best storage method and avoid wasting this valuable ingredient.

Expired Tomato Paste

Tomato paste expiration for canned products typically ranges from 1 to 3 years, and they often remain safe to use for months beyond the printed date. As long as the seal stays intact and the can shows no signs of denting, bulging, or rust, the paste should be safe to eat. Of course, if you store it well past the expiration date, the quality might decline, but unless damage affects the container, the tomato paste remains safe for consumption.

How to Store Tomato Paste?

Tomato paste usually comes in one of three types of containers: cans, glass jars, or tubes. But when it comes to storage guidelines, they are basically the same for each.
As long as the container is unopened, keep it in a cool and dry place, away from heat sources. And if it’s a glass jar, remember that it shouldn’t sit in sunlight.

The pantry or a kitchen cabinet is the natural place to store tomato paste. Just make sure the cupboard or shelf isn’t near the oven or a radiator.

Once you open the container, the tomato paste should be tightly covered and put into the fridge when not in use.

While sealing glass jars or tubes is not an issue, cans are more tricky.

You can seal those with cling wrap or a plastic bag and a rubber band. Or transfer the remaining paste into an airtight container or a glass jar.
