When drying or freezing products for winter of problems with container usually does not arise, however for conservation both the banks, and covers have to be not only are washed, but also correctly processed. That banks with preparations could stay long time, without having deteriorated, they have to be well sterilized.
Why carry out sterilization of covers and cans
Even on those covers and banks which seem clean there live the microorganisms capable to do harm not only to preparations, but also health much. Not microorganisms, but their waste products are terrible – they are quite poisonous and can provoke severe poisoning. Not to risk, all banks and covers should be sterilized.
For conservation it is necessary to choose covers free of defects, rust traces. If their surface colored, paint does not have damages. It leads to emergence of corrosion in the course of storage which negatively responds on products. Both covers, and banks have to be washed carefully up – the good result can achieve by means of plain baking soda. Further everything is just well washed with flowing water.
So-called "hot sterilization" sometimes nonpluses the beginning hostesses. If the jars are sterilized in different ways – both on couple, and in boiled water, and in the microwave oven, and in normal oven, then with covers so will not leave. Metal covers cannot be placed in the microwave, in oven they burn, and plastic foully melt.
Ways of sterilization of covers
Sterilization of covers can be carried out in several ways.
Pluses of these methods are obvious: the excellent quality of sterilization and additional expenses is not required.
The oldest and widespread way of sterilization which still our grandmothers – sterilization by means of boiling successfully used. For this purpose it will be required to take pan and to boil in it necessary amount of water, and then just to lower in cover boiled water. They should be boiled how to close banks with preparations. It is necessary to keep them in boiled water from two to fifteen minutes. Further it is necessary to arrive depending on material of which covers are made. Kapron it is possible to take in boiled water absolutely slightly, otherwise they can be deformed and on bank will not fit any more. Hot covers should be got from boiled water nippers. Before closing they need to allow to dry out. There is also one more way, but it will suit not all covers. It is possible to sterilize them in hot oven – but only metal and only those that without rubber inserts. Time for sterilization – about 10 minutes.
Advantages of processes are that they very fast, are not labor-consuming, and and pans all have ovens, unlike double boilers, for example – in them sometimes too sterilize both the jars, and covers.
Sometimes covers – warm up in any way at all some hostesses prefer to take a little them in solution of Furacilin, potassium permanganate or alcohol. This way is suitable both for tin, and for glass, and for plastic covers.
