Tomato paste—the intensely flavored, sweet and tangy condiment that adds richness to soups, sauces, stews or casseroles.

We all have that little can of tomato paste tucked away at the back of our cupboard for a rainy day; but do you know what it’s made from and how long it remains fresh?

If not, this blog post is here to answer your questions and demystify the wonders of tomato paste.

Here we will discuss topics such as its origin, shelf life when opened or unopened and storage tips so that you could start using tomato paste today in all your favorite dishes!

What is Tomato Paste?

Tomato paste is a thick, red paste made from tomatoes that have been cooked down and strained.

It is a concentrated form of tomato flavor and is used as a base or flavoring ingredient in many dishes.

Tomato paste is an essential ingredient in many Italian and Indian dishes.

It can be used to make pasta sauce, pizzas, curries, and more.

Tomato paste is also a great way to add depth of flavor to soups and stews.

Making your own tomato paste is very easy and only requires a few ingredients: tomatoes, olive oil, garlic, salt, and sugar.

First, the tomatoes are roasted in the oven until they are soft and beginning to blister.

Then, they are simmered on the stovetop with the other ingredients until they reduce down into a thick paste.

Store-bought tomato paste comes in a variety of forms: canned, jarred, or tube.

Tube tomato paste is the most convenient form since it doesn’t require opening a can or jar and can be stored in the fridge for months.

How Long Does Tomato Paste Last?

Tomato paste is a versatile ingredient that can be used in a variety of dishes.

It has a long shelf life and does not need to be refrigerated, making it a convenient pantry staple.

However, like all food products, tomato paste can eventually go bad.

Tomato paste will last for 2-3 years unopened and 1-2 years after opening.

The shelf life of tomato paste depends on a number of factors, including the best by date, how the paste was stored, and whether or not it has been opened.

Opened tomato paste can be stored in the fridge for up to 1-2 years.

Be sure to transfer the paste to an airtight container before refrigerating.

Unopened tomato paste can be stored in a cool, dark place like the pantry for 2-3 years.

Once opened, you can extend the shelf life of tomato paste by freezing it in an airtight container.

Frozen tomato paste will keep for 6-8 months.

When it comes to using tomato paste, trust your nose.

If the paste smells sour or rancid, it has gone bad and should be discarded.

You can also tell if tomato paste has gone bad if it has changed color or texture.

If thepaste is no longer red but has turned brown or black, it has spoiled and should not be used.

Finally, if the texture of thepaste is grainy or lumpy, it has gone bad and should not be used.

What are the Signs of Bad Tomato Paste?

Tomato paste is a thick, red sauce made from cooked tomatoes.

It is typically used as a flavor enhancer or to add color to dishes.

However, like all food products, tomato paste can go bad.

There are several signs that indicate bad tomato paste, including mold growth, changes in texture and color, and off-flavor.

Mold is the most obvious sign of bad tomato paste.

If you see any mold growing on the surface of the paste, throw it out immediately.

Mold can cause serious health problems if ingested.

Changes in texture and color are also indicative of bad tomato paste.

Tomato paste should be thick and smooth, with a deep red color.

If the paste is thinned out or has changed color, it is no longer safe to eat.

Off-flavor is another sign that tomato paste has gone bad.

If the paste tastes sour, bitter, or otherwise off, it should be discarded.

When in doubt, it’s always better to err on the side of caution and throw out bad tomato paste rather than risk eating something that could make you sick.

How Can You Extend the Shelf Life of Tomato Paste?

Tomato paste is a versatile ingredient that can be used in a variety of dishes.

It’s also a great way to add flavor and depth to your cooking.

However, like all food products, tomato paste does have a shelf life.

The good news is that there are a few simple ways to extend the shelf life of tomato paste.

One way is to store it in the fridge once it’s been opened.

This will help to prevent the growth of bacteria.

Another way to extend the shelf life of tomato paste is to freeze it.

This is a great option if you only use tomato paste occasionally.

Simply place it in an airtight container and it will last for up to six months.

Finally, one of the best ways to extend the shelf life of tomato paste is to make your own.

Homemade tomato paste is incredibly easy to make and can be stored in the fridge for up to two weeks.

Simply cook tomatoes down until they are very soft and then blend them into a smooth paste.

You can then store this in an airtight container in the fridge for future use.

Can You Freeze Tomato Paste?

Yes, you can freeze tomato paste.

Tomato paste is a great ingredient to have on hand because it adds a lot of flavor to dishes without adding any liquid.

Plus, it’s easy to store in the freezer for long periods of time.

When freezing tomato paste, be sure to put it in an airtight container.

I like to use freezer-safe zip-top bags because they are super easy to seal and don’t take up a lot of space in the freezer.

Just squeeze the tomato paste into the bag, seal it tightly, and lay it flat in the freezer.

Tomato paste can last in the freezer for up to a year.

When you’re ready to use it, just thaw it overnight in the refrigerator or microwave it for a few seconds until it’s soft enough to stir.

Conclusion

It is important to know how to store tomato paste properly to extend its shelf life.

Tomato paste can go bad if it is not stored in a cool, dark place.

The signs of bad tomato paste include a change in color or texture, mold, or an off odor.

You can extend the shelf life of tomato paste by freezing it in an airtight container.
