HOW LONG DOES FOOD KEEP IN A VACUUM SEALED CONTAINER?
The lifecycle of vacuum-sealed food depends on many factors, including: the initial germ count of the food, adherence to the correct storage and cooling conditions, and individual hygiene practices followed during preparation and vacuum sealing. The ZWILLING Culinary World app calculates the estimated longevity of the food based on the type of food stored (e.g. fresh beef or fresh vegetables) and the storage location (e.g. fridge, freezer, or pantry). Keep in mind, the calculated longevity is an estimated guideline.
HOW LONG DOES WARM FOOD STAY WARM IN THE CONTAINERS OR BAGS AFTER VACUUM SEALING?
Food should be allowed to cool at least to room temperature before vacuum sealing. Vacuum sealing warm food is generally not recommended. The Fresh & Save products do not offer insulation and thus will not keep food warm.
ARE ANY MATERIALS USED IN THE PRODUCTION OF FRESH & SAVE HARMFUL TO MY HEALTH?
All the components used in the production of Fresh & Save products are food-grade and checked for harmful substances.
HOW LONG IS THE FRESH & SAVE WARRANTY?
ZWILLING offers a 2-year warranty on Fresh & Save pump and containers.
CAN I STORE CHOPPED FRUIT, SUCH AS APPLES OR BANANAS, IN FRESH & SAVE CONTAINERS OR BAGS AT ROOM TEMPERATURE? OR SHOULD FRUIT ALSO BE REFRIGERATED OR FROZEN?
Vacuum sealing is not a replacement for the correct freezing, cooling, or storage of food. Depending on the food type, the standard storage practices generally recommended should be followed.
WHY DOES FOOD KEEP LONGER IN A VACUUM?
Vacuum sealing extracts air that surrounds food in a container, thereby markedly reducing the oxygen content of the container and delaying oxidization and aerobic processes. This results in food spoiling more slowly. Moreover, the minimal amount of air that is still present after vacuum sealing is unable to transport moisture to the surrounding environment, helping to prevent freezer burn and preserve flavors for longer.
HOW DO I KNOW IF THE VACUUM SEAL IS STILL SUFFICIENT? SHOULD/CAN I REPEAT THE VACUUM PROCESS IF NECESSARY?
The specially designed container lid also serves as a vacuum seal indicator. If the lid is sunken, a vacuum exists inside the container. If the lid is slightly raised, the vacuum should be refreshed. It is recommended that you check the vacuum from time to time, particularly when storing food long term.
HOW DOES REGULARLY OPENING THE CONTAINER AFFECT THE LENGTH OF TIME MY FOOD WILL STAY FRESH?
The less often that a food comes in contact with air, the longer it will remain fresh. When regularly opening a container or bag, it should be vacuum sealed again as quickly as possible after opening.
