Canned products have a fairly short shelf life after opening the can. When deciding how to store tomato paste for a longer period of time, you have to resort to various tricks. The product can be frozen, sterilized and repackaged, and natural preservatives can be added to it to prevent free access of air and prevent oxidation of the product.
Long-term storage of tomato paste
Tomato paste is a non-perishable product. That is why, for personal use, it is customary to buy it in soft portioned packaging for 1 use.
If the base for sauces and first courses is purchased in jars, the issue of its long-term storage becomes quite acute. You can solve the problem in different ways: from radical to simpler ones that do not require significant effort.
Sterilization
If there is a large volume of homemade or industrially produced tomato paste, it is better to solve the issue of its storage radically. The paste can be re-canned at home. In this case, you no longer have to decide how to store tomato paste - in the refrigerator or on a shelf in the pantry. The product will be completely ready for placement in any conditions. For sterilization you need:
- Place the product in a thick-bottomed container, grease it with oil.
- Put on fire, bring to a boil.
- Prepare sterile small jars with lids for preservation; screw or roll-up tin options are suitable.
- Divide the boiled mixture into separate containers. Seal tightly and cool.
After this, the product can be stored not only in the refrigerator, but also in any cool, dry place.
Storing tomato paste with oil
After opening a large container of canned product, the remaining mass must be used or disposed of quickly. You can extend this period by using the natural properties of sunflower oil.
It creates an airtight film on the surface, prevents the development of mold, and helps avoid drying out. It is enough to pour a thin layer of sunflower oil over the product; to enhance the effect, it is permissible to add dried garlic and turmeric. After this, the tomato paste can be stored for 2-3 weeks longer than usual.
Freezing
When purchasing sauce base in a tin, freezing it is the smartest solution for storing it. It can be done in different ways. Subsequently, without defrosting, the product is divided into portions for use. Popular freezing methods include:
- Using an oblong zip bag. The paste from the jar is transferred into it, giving the mass the shape of an oblong oval, and the clasp is closed. After complete freezing, the product is transferred to a new clean bag. As needed, you can take it out and use a knife to separate the desired amount of tomato base for preparing dishes and sauces.
- Using ice cube trays. It is better to take silicone or plastic products. The paste-like substance is laid out in them in portions, leaving a little space to the edge of the form, and sent to the freezer for 24 hours. After the ice is formed, it is removed from the container and transferred to a clean bag or plastic jar with a lid. This makes it quite convenient to store tomato paste for a long time, and it will be divided into convenient portions.
- Using a can as a form. For this freezing method, an opened container of tomato paste is used. Before sending for freezing, its top is covered with plastic wrap. To easily extract the mass, after 24 hours, dip the jar in boiling water for 3-5 seconds, then remove the contents - it will freely separate from the walls. The product frozen in this way is easily cut into portions 2 cm thick, packaged in individual bags, and stored in the freezer for up to 3 months.
Freezing is a simple and affordable way to preserve all the consumer properties of the paste if it is not used too often.
Mustard as a preservative
This method raises the most doubts, but it can also be considered when deciding how to store tomato paste in the refrigerator. It is enough to lubricate the neck of the glass jar, as well as the inside of the nylon lid, with the caustic sauce. Mustard will serve as a natural preservative and will prevent the development of pathogenic microorganisms inside the container.

It’s possible to store opened tomato paste for up to 3 months
Once you learn this trick, you won't have to overpay for small packets of tomato paste anymore. It turns out that you can store the contents of an open tin can for up to 3 months. The paste remains fresh and can be used as needed.
After using a couple of spoons of tomato paste, do not rush to put the contents of the tin in the refrigerator. Most likely, the paste will not be used rationally; some of it will begin to sour over time or even become moldy. Changing your diet to justify the cost is also not worth it. It’s much easier to take the advice and store the pasta in a special way.
Sequencing:
- Carefully open the can with a can opener on both sides.
- After removing the top lid, cover the jar completely with cling film.
- Place the pasta in the freezer overnight.
- We take the jar out of the freezer and, after waiting a few minutes, press the bottom.
- The contents of the tube move freely and end up in film.
Now it’s easy to cut the pasta into portions and package it. You can also cut off the required amount each time, sending the excess paste along with the tube back to the freezer.
You can do the same with pasta from a glass jar. In this case, you will have to make a tube from a plastic bottle and cut off the nylon cap, which will become the bottom.

Useful tips
Storing products with a limited shelf life requires careful attention on the part of the consumer. Do not eat food that has traces of mold on its surface. Fungal spores penetrate deep into the entire mass and are not localized on the surface.
When eating paste from an opened jar, use only a clean, dry spoon. You cannot keep the container open for a long time; after removing the required amount of tomato product, the lid is always returned to its place.
Preparation:
- Place the cutting board in a plastic bag, spoon the pasta onto it in small heaps and place directly on the board in the freezer.
- After the tomato paste has hardened, remove the board from the bag and simply turn the bag inside with the paste. Pieces of pasta will end up inside the bag.
- Store this package in the freezer.
- Frozen pieces of pasta do not stick together and are easy to remove from the bag. Each frozen piece is a tablespoon of tomato paste.
- We take our opened jar and cut off the slightly open lid.
- Cover with cling film and place in the freezer until completely frozen.
- When the paste has hardened, cut off the bottom cover, but do not throw it away.
- We run a knife along the inner walls on both sides to help the paste move away from the walls.
- Now we take the lid that we saved and use it to push the paste out of the jar.
- We cut off as much as we need, and wrap the rest in cling film and store in the freezer until next use.
To avoid this, you can store tomato paste in the following way:

Method one for preserving pasta
Tested by me personally. After you have opened a glass or tin jar with tomato paste or thick sauce, scooped out the required amount with a spoon, do not rush to close it - pour one spoon of any vegetable oil into it. That's all! Consider the problem solved. I mean seriously - everything is quite simple. The next time you take out a jar, when you open it, you will see, instead of the usual mold, a normal paste with a little oil on top. Scoop out as much as you need and put it back in the refrigerator. The main thing is that there is always oil in the jar, and you can add it if necessary.
The second way to preserve tomato sauce.
Very popular on the Internet. Freezing tomato paste. A very good method, especially suitable for long-term storage. But he has several options:
- You can freeze it immediately in the jar. This is especially convenient if you have tomato sauce rather than pasta. Before freezing, open the lid and cover it with a bag to prevent the product from airing. If you decide to use the frozen version of the sauce, take it out on the table and let the jar warm up a little to room temperature. Then lower the jar into boiling water for a few seconds - this will help you easily remove the contents from the jar. Then simply cut the ice paste into thick pancakes, put it in a plastic bag and put it back in the freezer.
- To avoid handling frozen pasta, first place tablespoons of it on a bag lined on a cutting board. Cover the top with another bag and freeze. After complete freezing, transfer small portions of pasta into a bag and store in the freezer.
The third way to keep pasta fresh
Simple, but dubious... Although I didn’t check it personally, I decided to share it with him. So, after opening a jar of tomato paste or sauce, grease the inner walls of the jar and the lid itself with mustard. It's that simple.
If you have your own secrets for storing tomato paste, write in the comments, we will be very interested!
In my opinion, for most people it is a problem to preserve tomato paste after opening. So I have suffered with this. It seemed like I always used a clean spoon and kept it in the refrigerator, but no, the paste still became moldy or covered with a dark, unpleasant crust. I had to throw it away in most cases. As a result, I started buying tiny jars of paste that looked like baby food. Thanks to this, I no longer threw away the pasta simply because there was none left. It seems that the problem has been solved, but no... It’s too expensive to buy these tiny jars, the price of which is not inferior to some larger volumes.
How to cook:
- Place the cutting board in a plastic bag, spoon the pasta onto it in small heaps and place directly on the board in the freezer.
- After the tomato paste has hardened, remove the board from the bag and simply turn the bag inside with the paste. Pieces of pasta will end up inside the bag.
- Store this package in the freezer.
- Frozen pieces of pasta do not stick together and are easy to remove from the bag. Each frozen piece is a tablespoon of tomato paste.
- We take our opened jar and cut off the slightly open lid.
- Cover with cling film and place in the freezer until completely frozen.
- When the paste has hardened, cut off the bottom cover, but do not throw it away.
- We run a knife along the inner walls on both sides to help the paste move away from the walls.
- Now we take the lid that we saved and use it to push the paste out of the jar.
- We cut off as much as we need, and wrap the rest in cling film and store in the freezer until next use.
Usually we only need a tablespoon of tomato paste to prepare a dish. We open the jar, use one spoon, and put the remaining paste in the refrigerator, where it usually sits forgotten until it goes moldy. There are two ways to conveniently store tomato paste after opening.
Natural and healthy. Homemade ketchup
Preparing it is not as difficult as it seems. The base is natural tomato paste. Fresh herbs will add new flavors to the sauce. It is enough to follow simple preservation rules so that the sauce can be stored for a long time in sealed bottles or jars. In addition, homemade ketchup is much healthier than any store-bought one, since it does not contain thickeners or preservatives. Using the “Box of Astrakhan Tomatoes” tomato paste allows you to independently control the desired balance of sugar and salt, because the paste itself does not contain them. This sauce can be used not only for meat, but also for spaghetti, lasagna or stew.
