What was the breakthrough in modern food packaging and canning and who developed this preservation method?

The breakthrough in modern food packaging and canning came with the development of the canning process by Nicolas Appert in the early 19th century. Appert discovered that food could be preserved by sealing it in jars and heating it to destroy spoilage-causing microorganisms. This method not only extended the shelf life of food but also made it safer for consumption, revolutionizing food preservation and storage. His pioneering work laid the foundation for the commercial canning industry that followed.
