Did you know that you can keep food fresh for up to 8 times longer by vacuum-packing it? As a result, you will not only reduce food waste but save money at the same time. Another important benefit of vacuum-packing food is its aroma-preserving property: Vacuum-sealing locks in all flavours while protecting food from contamination with unwanted odours at the same time. Vacuum containers are suitable for vacuum-packing fresh and dry food like fruit, vegetables and cereals as well as pureed fruit, and are just the perfect solution especially for pressure-sensitive and liquid food. These vacuum containers are designed for long-term use. The vacuum-sealing process takes place by use of a suction hose that is included in this set and can be attached to the lid's air valve of the container to extract air.
