When making blanks for the future, it is very important to observe sterility. All pathogenic bacteria during the processing of products and the preparation of storage containers must be destroyed. Canning jars must be cleaned with laundry soap or soda, then washed with running water. Then they are poured over with boiling water, steamed, placed for several minutes in an air grill or microwave oven, and the lids are thoroughly boiled.

The last moment may scare away some housewives, who will find such troubles for disinfecting containers a difficult task. And it’s completely in vain, because there are ways to sterilize jars for blanks that are available even to the most inexperienced young ladies.

It is affordable, roomy and easy to use. In it, you can disinfect lids (of course, only iron ones and without rubber inserts), jars, ladles and other necessary utensils before laying food.

Sometimes the recipe calls for the sterilization of jars with blanks. In the oven, this can be done without much difficulty. The meaning of the action is the complete destruction of all bacteria and fungi that can spoil canned food and harm human he alth.

First you need to carefully inspect the jars for chips and cracks. When heated, they can burst, so the sterilization of jars with blanks in the oven is carried out only if the containers are intact.

Then you need to properly prepare the container and put in it the necessary pickles, jams or marinades. Finished canned foods should be covered with lids without twisting them. Next, the sterilization of jars with blanks is carried out.

In the oven, containers are first placed on the grate, and only then the gas is turned on. It is necessary to monitor the temperature: it cannot be raised above 120 degrees, as the glass may burst.

The cooking time is indicated in the recipe. Usually it is 10-15 minutes for 0.5-0.7 liter cans and 20 minutes for 1 liter cans. After the required time has elapsed, the gas must be turned off, and the jars should be left for a while to cool down a little.

Caution, they bring hot

It is necessary to take out the dishescarefully, using special fabric or silicone tacks. An important point: they must be dry. Firstly, in order not to burn your hand through a damp cloth, and secondly, hot glass may crack due to temperature changes. Banks must be held by the sides, the neck can slip out of the hands, then burns cannot be avoided. Immediately after removal, the jars are closed with lids.

Pasteurization

Sterilization of jars with blanks in the oven involves a long-term high-temperature exposure to products, in which part of the biologically active substances and vitamins is inevitably destroyed. Pasteurization is carried out at a temperature of 75-90 degrees and is a more gentle way of processing products. It is used for compotes, marinades in which a lot of vinegar is added, or preparations that are not planned to be stored for a long time.
