lofttæming

Lofttæming, a Danish term, translates to "emptying the air" or "air emptying" in English. It is primarily associated with the process of vacuum packing or creating a vacuum seal for food preservation and other applications. In the context of food, lofttæming involves removing air from a food-safe bag or container before sealing it. This vacuum sealing significantly slows down the spoilage process by reducing the amount of oxygen available to microorganisms that cause decay.

The principle behind lofttæming is to create a low-oxygen environment. This not only extends the shelf life of perishable goods like meats, cheeses, and vegetables but also helps to prevent freezer burn when items are stored for extended periods. The absence of air also helps to maintain the texture, flavor, and nutritional value of the food. Beyond food, lofttæming can be used for non-food items, such as protecting delicate materials from moisture and air damage, or for compressing textiles to save storage space. The process typically requires a vacuum sealing machine, which evacuates the air and then heat-seals the bag.
