The preservation process is quite time-consuming and requires careful preparation, so every housewife should know the main points. We will start with the preparation, namely, how to sterilize the lids for seaming, to heat treat the glass jars, what it is for and how each stage takes place. We consider the main methods of sterilization of components for canning.
Preparation for sterilization
So, first of all, make sure that everything we need is at hand. We are talking about banks, lids, zakatochny key and a large saucepan.
Do not forget about forceps, because when boiling you use high temperature and you will not take a jar or lid with your bare hands!
Sterilization in simple words is a heat treatment that disinfects and cleans the surface of the lids and cans of microorganisms. The need for the process is to eliminate the possibility of fermentation, which may lead to damage to the preservation product. With banks, everything is simple - they need to be checked for the presence of chips and cracks, and then thoroughly cleaned. As for the covers, then you should be careful, the products must have the correct, that is, even shape without damage and bends.
"Do I need to sterilize the lids for seaming?" - Many housewives often ask this question. If you have a similar thought, this is already good, and here the answer is the obligatory norm. Remember that the result depends on the correct preparation. The purpose of this article is to help you achieve maximum quality in conservation.
If rust or pollution is noticeable on the covers, the paintwork on the inside is defective, or the surface is damaged by bending, then such a component cannot be used in conservation!
How to sterilize seaming covers?
One of the simplest ways we can isolate thermal cleaning in a double boiler. Here, both cans and lids for preservation can be sterilized simultaneously. To do this, thoroughly wash the jars and place them in the device. In cooking mode, set the time to 15-20 minutes. At the same time, you can also place the lids there immediately, the main thing is not to cover the neck of the cans so that the heat treatment process takes place inside the glass tank.
Features of the method:
- simply, quickly, saves your strength;
- in the kitchen will not be heat;
- is suitable only for those who have a double boiler;
- requires a large volume apparatus to sterilize several cans simultaneously.
We recommend sterilizing the cans and lids simultaneously, that is, at the same time, as sudden changes in temperature can affect the result. You will agree that it will be extremely unpleasant if a hot neck of a jar will crack due to the cold lid. The same temperature of the preservation components guarantees a safe roll-in, without any risk of damage. 
How to sterilize seaming covers with rubber?
One of the options is steam sterilization, it is best suited for covers with rubber gasket. Here it is worth remembering that the rubber part should receive a sufficient amount of steam, therefore - the lid should be installed so that the steam gets exactly on the bottom side of the lid.
There is a moment that should also be remembered - it is not necessary to remove the gum from the lid when it is heat treated. The thing is that it will be difficult to insert the rubber part in a heated state, despite the fact that the lid itself will also heat up.
How to sterilize screw caps for seaming?
Of course, sterilization alone is not enough, and even if the lid is twisted and not rolled up with a key, heat treatment is also necessary here. Microbes should not get into the container with preservation, so do not forget about the sterilization of screw caps.
A sure and reliable way is boiling in hot water. The action is performed immediately before rolling the cap. It is worth remembering how many minutes to boil caps for seaming, as a rule - from 10 to 15 minutes will be quite enough.
It is not recommended to sterilize covers for seaming in a dishwasher or in a microwave oven!
In general, the process of heat treatment of cans and lids for preservation is mandatory. Conducting sterilization, you guarantee the quality of the result - the absence of infection, turbidity, swelling of the caps due to fermentation.
Ways differ, but give one result. If it is steam, then pay attention to the position in which the jar or lid is located, perform all manipulations with hot objects using special tongs, in the case of heating in water - remember how much to boil the lids for seaming. Sterilization is a mandatory process, but an individual one. Sometimes the pasteurization of cans and lids can be combined, and in some cases it is simply unacceptable.
