Sterilization of cans is one of the most important stages in the preservation preparation process. There are many sterilization methods. Ovens are often used for this. This allows you to quickly and efficiently heat several cans at once. Experienced housewives know how much time it takes to sterilize containers in water or over steam. How is such sterilization carried out and how long do you need to keep the jars in the oven? This will be discussed below.
How to properly sterilize empty jars
Sterilization is essential in order for the jars to be stored for a long time. Without it, various bacteria will begin to multiply in the blanks. The toxins emitted by them are very dangerous for human health and life. With the help of the oven, you can carry out high-quality sterilization. In addition, the containers will not need to be additionally dried, which often takes a lot of time.
The advantage of this method is also that it is not necessary to warm up each jar separately. Several such containers will fit into the oven at once. In terms of spaciousness, the oven surpasses even the microwave, in which you can put no more than 5 cans. In the oven, you can sterilize both empty containers and filled with workpieces. And it doesn't matter what exactly you roll. It can be both various vegetable salads and pickled cucumbers and tomatoes.
Before sterilizing empty containers, make sure that the dishes are free of any defects. Cracked or chipped containers can easily burst when heated. The jars should also be free of any stains.
Then the containers are turned over and left to dry. Now you can start the sterilization itself. All containers are placed in the oven upside down. If the cans are not completely dry yet, then they are placed upside down. For sterilization in the oven, set the temperature within 150 degrees. Half-liter jars are kept in the oven for at least 15 minutes, but three-liter containers will have to be heated for about 30 minutes.
Important nuances
It is possible to get jars out of the oven only with the help of special gloves or a kitchen towel. So that the can does not suddenly burst, it is necessary to carefully place it on the surface with the neck down. To keep the jars cool slowly, you can cover them with a towel on top.
Be sure to hold the jar with both hands so that in case of something it does not fall and hurt you. Then the question may arise, what to do with the lids? It is undesirable to sterilize them in the oven. Lids, like jars, must be thoroughly rinsed, and then placed in a pot of water and boiled for 15 minutes. To remove the lids from the pan, it is best to drain the water first or use tongs.
Sterilizing cans in an electric oven
Owners of electric ovens can also sterilize cans in this way. In this case, it does not matter at all what shape and size the oven itself is. The whole process is as follows:
- The cans are washed thoroughly using baking soda as in the above method. Then the containers are laid out on a towel to dry.
- Do not forget that wet jars must be placed with their neck up, and the rest are turned upside down.
- Metal lids can also be sterilized in an electric oven. They are simply laid out next to the cans in the oven.
- We set the temperature to about 150 ° C. We heat three-liter containers for 20 minutes, and half-liter containers for about 10 minutes.
As you can see, using an electric oven can significantly speed up the sterilization process. You also need to take out the cans carefully, using oven mitts and towels. It is necessary to put sterile jars only on a clean, washed surface, otherwise all the work will be in vain and bacteria will again fall into the container.
Attention! With a sharp jump in temperature, the jar may burst, so it is better to immediately cover the containers with a towel. So, the heat will be stored much longer.
How to sterilize jars of finished blanks
There are many advantages to using ovens for sterilization. These seams are perfectly stored and almost never explode. Thanks to heating, the container is not only sterilized, but also dried. This saves time for additional drying of containers, as after processing over steam. In addition, your kitchen will not increase the level of humidity due to the boiling liquid. This process does not cause any inconvenience. You don't even have to fish hot cans from boiling water.
In addition to empty containers, ready-made seams can also be sterilized in the oven. This is also pretty easy to do. The process is as follows:
- The jar is filled with a blank and the container is placed in water. The cover is not needed at this stage.
- We set the temperature to 150 degrees. When the oven heats up to this level, we timed ten minutes for half-liter jars, 15 minutes for liter containers and 20 minutes for 3 or 2 liter pieces.
- When the required time has elapsed, the jars are taken out of the oven in turn and rolled up with special lids.
- Further, the cans are turned upside down and left so until they cool completely. To cool the jars slowly, cover the canning with a blanket.
- A day later, when the jars are completely cool, you can transfer the containers to the cellar.
Conclusion
Even cooking does not stand still. Everything old is changed to newer and more practical. It is so good that with modern technology you no longer need to boil huge pots of water, and then, at the risk of burning your fingers, hold jars for blanks above them. Using the oven for these purposes is much more convenient and faster. No steam, stuffiness and bursting cans, which often happens during the boil. It is possible to list all the advantages of this method for a very long time. But it's better not to talk about it, but to try it. So if you have not yet had time to try this wonderful method, then do not wait for next summer, try it as soon as possible.
