Vacuümverpakking, also known as vacuum packing or vacuum sealing, is a method of packaging that removes air from the package before sealing it. This is typically achieved using a vacuum sealer machine, which creates a partial vacuum inside a plastic bag or container and then seals the opening.

The primary benefit of vacuum sealing is to extend the shelf life of food products. By removing air, it significantly slows down the oxidation process and inhibits the growth of aerobic bacteria and fungi, which are the main causes of spoilage. This makes vacuum-sealed food last considerably longer than when stored using conventional methods like plastic wrap or containers.

Beyond extending shelf life, vacuum sealing also offers other advantages. It helps to preserve the freshness, flavor, and nutritional value of food by preventing contact with air. For meats, it can prevent freezer burn by eliminating air pockets. In some cases, vacuum sealing can also reduce the volume of the food, making storage more efficient.

The technique is widely used in both commercial food production and by home cooks. It is particularly popular for preserving meats, cheeses, vegetables, and other perishable items. Specialized vacuum sealers are available for both household and industrial use, with variations in features and sealing capabilities. It's important to note that while vacuum sealing inhibits aerobic organisms, it does not prevent the growth of anaerobic bacteria, such as Clostridium botulinum, which can thrive in the absence of oxygen. Therefore, vacuum-sealed perishable foods still require refrigeration or freezing to prevent spoilage and ensure safety.
