The origins of canned food
Canning is a method of preserving food, and it can refer to canned beverages—such as canned soda, coffee, juice, frozen milk tea, beer, and more—or canned foods like luncheon meat, typically packaged in tinplate. Opening these cans traditionally requires a can opener, though some products now feature technology that mimics the easy-open lid design. Today, most canned goods are sealed using aluminum alloy packaging, and the modern opening mechanism often resembles the popular pull-tab design, making them incredibly convenient to use.

Why do canned foods stay fresh for a long time without the use of preservatives?
After food is packed into cans, it undergoes processes such as degassing, sealing, and sterilization. Once the container is completely sealed and placed in an oxygen-free environment, the sealed food reaches a sterile state. In this condition, microorganisms (including bacteria) lack the necessary conditions to grow or multiply, while external bacteria are effectively prevented from entering the can. As a result, the food remains fresh and free from spoilage—eliminating the need to add any preservatives at all.
