We can hardly imagine today the time when canning has not yet been discovered, because it is through canning technology that we can keep our products for a much longer time and eat fruits and vegetables, even when they are not in their growing season..
Cans are also easily portable, the chemical composition of the products they contain can be controlled and the digestibility of the starting products can be increased.
Canned meat, for example, definitely becomes easier to digest and much more tender, and there is nothing better than eating strawberries or raspberries in December, especially if the products you preserve are homemade.
The purpose of canning is to destroy the microorganisms in the products so that they can last longer. The methods of this process can be by subjecting them to low or high temperature, by the addition of chemicals or by the action of gamma rays.
Today, most products at home are preserved by sterilization or drying.
Here's what you need to know about canning technology to make sure you've produced quality processed products:
1. When picking fruits or vegetables, you need to inspect them carefully to make sure they are fresh and healthy. It is good to preserve on the same day as the picking.
2. The processing time of fruits and vegetables depends on their maturity and size, so you must sort them.
3. In order to reduce the amount of microorganisms, all products must be thoroughly washed under running water. If necessary, some of them are peeled and planed.
4. Some products need to be blanched before canning. The goal is to reduce their volume and destroy the enzymes that cause them to darken.
5. When filling jars, the products should usually be up to 1 cm below the top edge of the jar, after which they should be filled with water.
6. All jars are tightly closed and arranged in a large container, which is filled with water reaching 5-6 cm above the jars.
7. The sterilization time depends on the products, but it should be noted that it is taken into account from the moment the water starts to boil. Once the jars are ready, they cool, but not immediately because they will burst.

Pasteurization Technology
Pasteurization is a type of canning in which what is pasteurized can last longer than if it is unprocessed or fresh. The method of pasteurization was invented back in 1862 by Louis Pasteur and Claude Bernard, who studied the processes of fermentation and is widely practiced today, especially when it comes to storing milk.
