Tomato paste is the base ingredient for some of the most delicious dishes like pasta, taco filling, meat loaf and much more. Tomato paste can be made at home and can also be store bought, but either way, tomato paste is concentrated tomato sauce without the added flavorings and contains some preservatives only.
Some tomato pastes can also have additional herbs and spices for that added tang which is all the more better for cooking more versatile dishes.
Tomato pastes are often bought in bulk because they are a staple ingredient in most dishes. But you have to ask, will the tomato paste go bad? And that is what we are going to find out here.
How Long Does Tomato Paste Last? Does Tomato paste go bad?
Even though tomato paste is a staple ingredient for most dishes, most of the dishes call for only an amount, which does not require you to use the full can.
And on top that, most tomato pastes come in cans, which makes it even more problematic for storage as you need to find an airtight container to store.
But as long as you store it in an airtight container and in the fridge, the tomato paste can still be good to use over the next three to five days.
Another way of prolonging the shelf life of tomato paste is freezing it in a bag or in the form of cubes. In which case, its life can be extended for the next three months, provided it hasn’t been thawed.
Canned tomato paste that is still sealed can be stored way beyond its best-by date by six months. But it should be stored away from the sun and should be stored in a cool place. Tomato paste tubs can last for forty-five days even after it has been opened.
How to Tell if The Tomato Paste Is bad?
Tomato paste is moist naturally, so if it has gone bad, it will be most probably because it is a hub for mold. Tomato paste will have a moldy surface which can range from greenish to yellowish, which should be thrown out immediately.
Spoiled tomato paste will also give away an off odor which would be pungent and sour smelling, in a way that it does not smell like tomatoes at all. You should not try to salvage it at any cost.
In general, if you feel like it has been sitting for so long in the fridge, then it is most probably time for it to be thrown out.
