Canning is an important and safe method for preserving food if used properly. The canning process involves placing foods in jars or similar containers and heating them to a temperature that kills microorganisms that cause food to go of. During this heating process air is forced out of the jar and as it cools a vacuum seal is formed. This vacuum seal prevents air from getting back into the product bringing with it contaminating microorganisms.
Canning helps to preserve food by removing the air from the food. This causes the food to decompose much less quickly or not at all.
You put water in the pressure canner which helps create steam when the lid is twisted on. The pressure builds up and seals the jar lid which helps preserve the foods you are canning.
Simply stated, the canning process kills off bacteria that spoils food by means of salt, acid, and/or heat and sets up a vacuum seal so that the canned food cannot be contaminated.

Usually food is not cooked before it is canned. However, all food is cooked during the canning process. There may be a few reasons why you would cook food before canning. Cooking may help dissolve things like pectin or thicken things like starch. Cooking may also help extract flavors from ingredients. Also, food is almost always heated before canning to help remove atmospheric gasses from the can.

Nicolas Appert developed the method of canning to preserve food by sealing it in airtight containers. This method involved heating the food to kill bacteria and sealing it in airtight containers to prevent spoilage, enabling the food to be stored for long periods without refrigeration. Napoleon's army utilized canned food as a portable and convenient source of nutrition during long military campaigns.
It makes meat fresh and makes it last longer
Additives are put into food to make it taste better, look better and last longer. Sometimes, substances are merely applied topically. For example, ethylene gas is used to change the color of green oranges to orange, and carbon monoxide is used to restore or preserve cut meat's bright red color. Even at home, we put additives into our food, for the same reasons. Salt, sugar and vinegar can be used to help preserve food.
