Keep food fresh up to five times longer with this FoodSaver? FFS001 Urban Vacuum Sealer. Oxygen and moisture in the air causes food to degrade leading to a loss of flavour texture and nutritional value. Conventional storage such as plastic wrap and ordinary containers contribute to the problem by trapping air inside. FoodSaver Vacuum Sealing Systems remove air preventing it from coming into contact with your food. The patented technology is proven to extend food freshness by up to five times. The simple-to-use automated vacuum sealing system allows you to vacuum seal your food. Your food can then be stored in the fridge freezer or pantry. It can be boiled in a pan to re-heat or cook or placed into a water bath for those into their Sous-Vide cooking. Food within the bags and rolls can even be defrosted in the microwave.
