The canning industry involves the preservation of food by sealing it in airtight containers, typically metal cans. This process helps to extend the shelf life of various products, including fruits, vegetables, meats, and soups. The industry plays a crucial role in food safety and convenience, allowing consumers to store and consume food over long periods without spoilage. Canning began in the early 19th century, with Nicolas Appert credited for developing the method. Today, the industry has evolved with advanced technology, ensuring efficient production and quality control. Major companies in the canning industry focus on sustainability and reducing waste while meeting consumer demand for ready-to-eat meals.
