The concept of hermetically sealed canned food is one that goes back to the late 19th century. The idea of preserving food in cans and other containers so that it could be transported and stored for a long period of time was revolutionary. Canned foods are still widely used today, but how does hermetic sealing work?
Hermetic sealing is a process that involves sealing a container in a way that makes it impermeable to air and moisture. This is done by using materials such as metal, rubber or plastic, which are heated up and then cooled to form an airtight seal. Hermetic sealing also prevents bacteria, mold and other microorganisms from entering the container, which helps keep food safe for long periods of time.
The most common type of hermetically sealed can is the tin can. Tin cans have been around since 1810 when Peter Durand invented the first tin canning process.
Tin cans are made from thin sheets of metal rolled into cylinders or rectangles and then joined together with soldering or welding. This creates an airtight seal which keeps food safe from spoilage.
Modern canned foods also use other types of hermetic seals such as plastic lids with rubber gaskets built into them. These lids are designed to fit tightly around the top of a can so that no air or moisture can get inside. This helps keep canned foods fresh for longer periods of time.
Hermetically sealed canned food has become a staple in many kitchens around the world because it is convenient, safe, and cost-effective. Canned goods are also easy to store, transport, and prepare – making them ideal for a variety of recipes.
Conclusion:
Yes, canned food is hermetically sealed in order to keep it fresh for longer periods of time and free from spoilage due to air and moisture exposure. This process involves using materials such as metal, rubber or plastic to create an airtight seal which prevents bacteria, mold and other microorganisms from entering the container. Tin cans have been used since 1810 while modern cans often use plastic lids with rubber gaskets built into them for extra protection against spoilage.
