The canning industry involves the preservation of food by sealing it in metal containers, known as 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 distribution, ensuring that safe and nutritious options are available year-round. Canning began in the early 19th century, largely due to the work of Nicolas Appert, who developed the method of sealing food in glass jars. Today, the industry has evolved with advanced technology, allowing for mass production and improved safety standards, making canned goods a staple in many households worldwide.
