How Long Does Tomato Paste Last in the Fridge Tube?

Tomato paste is a product that lasts longer.

It can last for months if you keep it sealed up tight and away from moisture and air. 

Some ways to help extend its shelf life: Store it in a relaxed environment and don’t open it often.

In addition, if tomatoes are left too long after processing, they begin to lose their shape due to osmosis (the process by which liquids move through porous materials).

It depends on a few factors.

The essential thing to consider is the tomato paste’s expiration date.

If it has an expiration date, then you can be sure that it won’t have deteriorated much by the time you get around to opening your fridge and getting ready for dinner.

If there isn’t an expiration date on your tube of tomato paste, several things could affect how long it will last in your fridge.

These include:

1) The type of tomato paste (e.g., regular or dried).

To extend the life of your tomato paste beyond two weeks, consider freezing it.

To do this:

1) Place the tomato paste in freezer bags or other containers with plastic wrap on top (to prevent freezer burn).

Does Tomato Paste Actually Expire?

Tomato paste does expire.

But it will not look or taste like fresh tomato paste after it’s expired.

The main reason the shelf life of tomato paste changes is because of the acidity of the tomatoes used to make it.

If you’re using a high-acid tomato, your paste will keep longer than if you’re using a low-acid tomato.

If you’re unsure about how long your tomato paste has been sitting out, consider this:

if it smells bitter, then it’s probably expired; if it starts to turn gray and slimy, then it’s expired; if it tastes off, then cool—but set aside for another use.

You should always use unopened jars of tomato paste within two weeks after opening them.

If you have opened jars sitting around for extended periods, they may have become contaminated.

They could contain bacteria that can cause infections or cause sickness if eaten.

If you want to ensure your tomato paste doesn’t go bad before you use it, store it in an airtight container away from light and heat—both of which will speed up spoilage.

  • 1 Jar


  • 10 pounds tomatoes
  • 2 tablespoons olive oil
  • 2 teaspoons sea salt
  • 1/2 teaspoon citric acid


  • the oven to 350 degrees Fahrenheit. Set up two racks to divide the oven into thirds, then preheat it to 350 degrees.
  • Slice the tomatoes into fourths. tomato slices in fourths.
  • Olive oil and tomatoes are simmered together. Place the olive oil in a large pot over medium-high heat until shimmering. Tomatoes should be added and cooked until tender and the peels start to separate from the tomato flesh.
  • Use a food mill to process the tomatoes. Push the warm tomatoes through a food mill, sieve, or chinois to separate the tomato pulp from the seeds and skins. The pulp should be mixed with sea salt and lemon juice or citric acid. Discard or compost the seeds and skins.
  • Put the pulp on two baking trays. The tomato pulp should be divided between 2 sizable, rimmed baking sheets. You can also use a large roasting pan, but it will take longer to cook down that way.
  • Bake the tomato pulp until reduced to a paste. In the oven, put the baking sheets. Check the tomatoes every half hour, stirring the paste and altering the position of the baking sheets so that they decrease evenly. Over time, the paste will start to diminish to the point where it doesn’t fill the baking sheet any more. At this point, merge the contents of the two baking sheets into one and continue to bake.
  • Bake for a reduction of at least 50%. The paste is done when shiny, brick-colored, and reduced by more than half, 3 to 4 hours, though exact baking times will depend on the juiciness of your tomatoes. There shouldn’t be any remaining water or moisture separating from the paste at this point.

  • Preserving Option 1 – Process the tomato paste in a hot water bath. Apply lids and rings and process in a boiling water bath for 15 minutes. For up to a year, keep in a cool, dark place. After opening, refrigerate for up to 1 week.
  • Option 2 for preservation: Freeze or refrigerate. If you don’t want to process the paste, you can chill or freeze it instead. Paste should be scraped into tidy half- or quarter-pint jars. Place a layer of olive oil on top of each jar before putting it in the freezer or refrigerator. It will keep in the refrigerator for 3 to 4 weeks as long as you keep it well-covered with olive oil and make sure you only take it out of the jar with a very clean spoon. It can be frozen and kept for up to nine months.
