The ideal temperature for each type of food
The interplay of the ideal humidity and the ideal temperature is key to lengthening storage life and protecting nutritional content. Different types of food have very different storage requirements, for example, high-quality ham matures in dried Alpine air, mangos grow at high humidity levels and cheese develops its flavour in cool caves. The storage conditions in the BioFresh drawers can be adjusted to provide the optimum storage climate for different types of food.
Customised food storage with BioFresh
Meat and dairy products
In terms of temperature and humidity, meat products are extremely demanding, and they are best stored in the BioFresh DrySafe. The DrySafe environment, with low humidity and a temperature of just above freezing, significantly reduces the activity of micro-organisms, which greatly extends the storage life of meat products. This environment is also perfected suited to storing milk, cheese and yogurt.
Fruit and vegetables
The high water content of fruit and vegetables means that they need to be stored at a high humidity level. The BioFresh HydroSafe creates an ideal climate for fruit and vegetables, with precise electronic controls maintaining a constant temperature of just over 0°C. These optimum storage conditions not only prevent the food from freezing but also prevent it from drying out and, to a large extent, preserve the food's valuable nutritional content.
Retailers store fish and seafood on ice, and for good reason: their ideal storage temperature is at freezing point. Constant, uniform low temperatures are essential and, with a maintained ambient temperature of just above 0°C, the BioFresh safe is ideal for storing fish. In combination with the DrySafe setting, refrigerated fish and prawns will stay fresh for much longer.
Multiple climate zones in a single appliance
BioFresh technology is based on the observation that food stays optimally fresh when stored at just above freezing point. The temperature in the BioFresh drawers is therefore constantly maintained at just over 0°C. These drawers act as freshness safes, each of which offers optimal conditions for certain types of food – and all in just one appliance.
For even greater flexibility: BioFresh-Plus
In BioFresh-Plus appliances, the temperature in the top BioFresh safe can be set precisely to the required degree, and a sliding control allows you to set the required humidity. As a result, the compartment can either be used as a HydroSafe or a DrySafe. BioFresh and BioFresh-Plus technologies transform refrigerators into highly versatile storage spaces in which the broadest range of food can be stored under ideal conditions.
BioFresh safes at a glance
If the BioFresh safe is set to HydroSafe, the humidity increases, and the HydroSafe climate keeps unpackaged fruit, vegetables and salads crisp and fresh for much longer. Precision electronic controls enable the temperature to be accurately maintained at just over 0°C so, even with high humidity, food will not unintentionally freeze.
When the slider is open, the humidity falls and the BioFresh safe becomes a DrySafe. Low humidity conditions are ideal for storing packaged fish, meat and dairy products. When stored in this comparatively dry environment, these products retain their flavour for far longer than in a traditional refrigerator compartment – cheese, for example, for up to 100 days.
The BioFresh-Plus safe offers maximum flexibility. Its independent electronic control system means that you can set the top safe temperature to the exact degree. Fish and seafood stay fresh for longer at -2°C, whereas delicate tropical fruits are best kept at +6°C. With BioFresh-Plus the temperature in the top BioFresh safe can be quickly and precisely adjusted to accommodate whatever food you want to store.
Incidentally: a temperature of just over 0°C is perfect for storing fresh food but it's not necessarily the perfect consumption temperature. The full flavour of cheese only develops at room temperature and fruit tastes far better when it is not quite so cold. Even meat should be allowed to warm to room temperature before being cooked. Although you should store food in the refrigerator at a constantly cool temperature, you ought to remove it in good time before eating or cooking.
A place for every type of food
People's tastes vary and therefore, people have different refrigeration needs, for example, people who don't eat meat or dairy products need more space for fruit, vegetables and salad. But, whether you're a vegetarian or a steak lover, Liebherr's BioFresh refrigerators offer plenty of highly versatile storage space, which can be used however you want.
Arrange your refrigerator according to your needs
The BioFresh drawers have a highly practical design that enables you to keep stored produce organised, making it easier to view and find items, especially if add the easy to clean FlexSystem. These spacious drawers, open with great ease as they are set upon telescopic rails, and being transparent they conveniently facilitate the sorting and viewing of stored items. Meanwhile, in the refrigeration compartment, a variety of innovative shelving and storage solutions mean there is ample of space to keep food that does not have specific humidity requirements. Features such as the variable egg tray, VarioSafe and VarioBoxes promote order within the refrigerator. View our full accessory range for more fridge organisation ideas!
To store food optimally, you need to have a clear overview of and quick access to the things that you're looking for. Good interior organisation makes shopping easier as a quick look in the fridge will immediately tell you what you've run out of, so you can shop more specifically. It also prevents food being hidden out of sight, forgotten about and going off. BioFresh helps you to sustainably manage your food storage in two ways: food stays fresh for far longer and you can optimise your stocks with less waste.

Market freshness enjoyed at home
More and more people value a carefully balanced diet. The key to achieving this is eating fresh, high-quality food that's packed with important vitamins, trace elements and minerals. These nutrients provide energy, strengthen the immune system and support the metabolism in a completely natural way. The fresher food is, the higher its nutrient content. Although we rarely have time to go shopping every day, we do not want to manage without fresh food and therefore we need innovative technologies to help us store food for longer, while retaining its taste, texture and valuable nutrients.

Liebherr's BioFresh technology enables you to store your food in specialised refrigerator compartments that offer the optimum individual environments for fruit and vegetables, fish, meat and dairy products. The customised interplay of temperature and humidity ensures that the food's flavour and nutrients are retained for far longer. BioFresh refrigerators also offer extremely practical interior features and functions, plenty of storage space and a clear view of the items stored. Not only does a Liebherr appliance help you keep your food fresh for longer, it also helps you save time by storing items efficiently.
