Hermetiserte

Hermetiserte is a Norwegian term that translates to "hermetized" or "sealed" in English. It primarily refers to the process of sealing food in airtight containers, such as cans or jars, to preserve it. This method is widely used for a variety of food products, including fruits, vegetables, meats, and fish, extending their shelf life significantly and preventing spoilage by inhibiting the growth of microorganisms.

The hermetic sealing process typically involves placing the food into a container, which is then sealed, followed by a heating or retorting process. This heat treatment kills any existing bacteria, yeasts, or molds and inactivates enzymes that could cause spoilage. The airtight seal ensures that no contaminants can enter the container after processing, thus maintaining the safety and quality of the food for extended periods, often for years.

Products that are hermetiserte are commonly found in grocery stores and are a staple in many households due to their convenience and long shelf life. This preservation technique allows for food to be consumed out of season and reduces food waste. The term itself emphasizes the complete and secure nature of the sealing, guaranteeing protection from external environmental factors.
