People often use various additives when cookingThis is because these additives improve the taste of food and deprive it of its original taste. Meanwhile, one of the most widely used food additives in cooking is tomato paste. In addition to giving the food a great texture, tomato paste and its combination with some ingredients is very attractive and also gives the food a nice color. Tomato paste is relatively easy to prepare and does not contain any additional ingredients. However, there are two different processes a manufacturer can use to make it: a cold process and a hot process, each resulting in different consistency and color. Because tomato paste is a perishable item, a reliable storage strategy is required for it. You may keep it in the refrigerator, but if you want the shelf life of the can of tomato paste to be extended, you can keep it in the freezer instead. Tomato paste from a can that has been opened may be kept, even if the can has not been refrigerated. 
How long does tomato paste last in the fridge
Cans, glass jars, and tubes are the common packaging options for tomato pasteYou want to know how long tomato paste will keep in the refrigerator after you purchase it, regardless of the packaging it comes in Store-bought sauces that come in tins or cans often include a significant amount of preservatives to lengthen the product's shelf life. Once they have been opened, the length of time that these sauces may remain fresh on the shelf varies from brand to brand. When a container is opened, it indicates that the tomato paste has to be stored in the refrigerator and the correct packaging. You should keep the container in a cool, dry area that is free from any sources of heat until it is ready to be used. The unopened jar of paste has a shelf life that is readily extended by many months beyond the date printed on the label. If stored in a refrigerator and properly packed in an airtight container, it has a shelf life of seven to ten daysWhen stored in a glass jar, it will keep for two or three days longer than when stored in an unsealed can after the can have been opened for five days. tomato paste in tubes stays longer than in other forms; after being opened, the tomato paste can keep longer, 6-8 weeks, in the fridge. 
What to do with the leftover tomatoes
Canning them or turning them into something else that may be eaten is what you can do with leftover tomatoes, such as salsa or sauce, which are also options for dealing with excess tomatoes that you have on hand. You may put them in the freezer to use later for sauces, spaghetti, soup, or any other dish. If you want to use them within the next few days, you may keep them in the refrigerator (but not in the tin) until you are ready to use them. When you are making meatloaf, you may include the hamburger with these ingredients. If you make meatballs, you may put the meatballs in spaghetti sauce, and then put the sauce on top of the meatballs. There is an infinite number of options; Salsa, sauces, stewed (roasted and not), mixed with other vegetables that pair well (peppers, onions, garlic), and preserved (canned, pickled, frozen) so that when another meal comes up for which you would usually reach for something that came from a grocery store shelf, you can instead use what you have saved up for that particular occasion.

You have some leftovers, but you're not sure what to do with them. Do not squander the flavor that comes from those ripe tomatoes. Instead, you should freeze it so you may use it in another recipe. You will not only save money, but you will also avoid wasting the concentrated tomato flavor and thickening power that it has, both of which are quite essential in the kitchen. To preserve tomato paste for later use, simply measure out any leftovers into tablespoon-sized servings on a plate, then place the dish in the freezer for a few hours. Once the sections have been frozen, they will be simple to pop off the plate and you will be able to move them to an airtight container or a resealable plastic bag. You should label the container or bag to indicate that each portion is one tablespoonTomato paste can last for around two to three months in the freezer if it is properly stored. Add the frozen parts straight to the recipes as they are asked to get the most out of their flavor. 
How to store tomato paste without a fridge
Because of this, tomato paste is often purchased either in a box or in large quantities; nonetheless, there is always the risk that it may go bad. so, it is very important to know how to store it without a fridge. It is almost difficult to prepare many meals in the kitchen without using tomato paste since it is the condiment and pantry staple that is considered to be the most essential in all cuisine. It would be difficult to go to the store every time you ran out of it. Due to this issue, people prefer to buy more than one container. Tomato paste can go bad if it is not stored properly. As long as the container has not been opened, it should be stored in a location that is cold, dry, and away from any sources of heat. Also, if the container is made of glass, keep in mind that it must not be left in direct sunlight. But once, it is opened, it should be kept in the fridge because tomato paste, particularly the store-bought ones, is a perishable food that goes bad quickly out of the fridge. To maintain both its taste and its shelf life, the paste, whether it is packaged in a tube, a glass jar, or a can, has to be chilled once it has been opened. 
Open tomato paste can
Once you open a can of tomato paste, you should be aware that it can last just for 5- daysIf you want to utilize all of the contents of the can, you will need to pour them into a different container after you have left the lid off for a significant amount of time ( a glass jar). after opening the lid of the can there is a very high chance that one of the ingredients in the food (especially the acid) will react with the metal walls of the jar inside, and if you pay attention, you have seen, for example, if the pineapple remains in the jar, and the water will turn gray after a while, so it is better to pour it into another container (preferably a glass) after opening the jar. 
When you open the lid of a can of tomato paste, it is almost hard to shut it again. However, moving the tomato paste to another container makes it easy to do so, and securely sealing the container protects food from being contaminated. This is another crucial aspect. On the other hand, one of the primary reasons why mold develops both in cans as well as glass containers is because the food is exposed to the same pollutants in both types of containers. Because of this, food contamination and mold may be avoided by paying attention to hygiene procedures, such as extracting the paste from the container using a spoon that is dry and clean.
