Not all types of food need the same temperature and humidity, so Liebherr introduced an additional temperature zone ‘BioFresh’, where many types of food can be kept fresh significantly longer than in a traditional refrigerator compartment. Keeping the temperature at just above 0°C combined with high humidity (HydroSafe) results in fruit and vegetables staying fresher for longer, while a dry environment (DrySafe) is ideal for storing meat, fish and dairy products.
With BioFresh, not only is the appearance and fresh flavour maintained but first and foremost, the valuable vitamins and minerals our bodies crave are preserved much longer. Research* revealed benefits of a BioFresh drawer compared to a normal refrigerator included 92% higher vitamin C values, with some foods even showing an increase in vitamin C content. Weight retention during storage was also increased by 68.3% on average and wastage in preparation was significantly reduced.
Meat and dairy products
Low humidity and a temperature just above freezing point are the ideal storage conditions for meat and dairy products. BioFresh with the DrySafe setting provides this type of climate and keeps it constant at all times.
Fruit and vegetables
Fruit and vegetables are best kept in the HydroSafe with high humidity. A precision electronic control system ensures the temperature is maintained at just above 0ºC, preventing damaging frostbite.
Please note: For storage of fish and seafood with the DrySafe setting please refer to BioFresh Plus.
