Tyhjiöpakattu

Tyhjiöpakattu is a Finnish term that translates to "vacuum-packed" in English. It refers to a method of food packaging where the air is removed from the packaging before it is sealed. This process significantly extends the shelf life of the food by slowing down the oxidation and spoilage processes.

The vacuum packing process typically involves placing food into a plastic bag or container. A vacuum sealer machine then extracts the air from the bag, creating a tight seal around the food. This absence of air prevents the growth of aerobic bacteria, which require oxygen to survive and multiply.

Tyhjiöpakattu is widely used for preserving a variety of foods, including meats, cheeses, fish, vegetables, and fruits. It is also beneficial for sous vide cooking, as it ensures even heat distribution and prevents water from entering the food during the cooking process. Beyond food, vacuum sealing can be used for non-food items to protect them from moisture and air damage, such as important documents or clothing for storage. The reduced volume also makes vacuum-packed items more compact and easier to store or transport.
