Canning of food

Canning is a method of preserving food by sealing it in airtight containers, usually metal or glass cans. The process typically involves heating the food to kill harmful bacteria and enzymes, which prevents spoilage and extends shelf life. Once sealed and cooled, the cans create a vacuum that helps preserve the food's flavor, nutrients, and safety. Canned foods can last for years without refrigeration, making them a convenient option for long-term storage. Commonly canned items include fruits, vegetables, soups, and meats, providing an easy way to enjoy seasonal produce year-round.
