The quality and freshness of food is key to health and well-being. Nature offers a perfect spectrum of nutrients: vitamins, minerals and carbohydrates that give energy, boost stamina and enhance mood. When stored at the right temperature and humidity, foods retain their delicious freshness and flavour for much longer. This blog looks at how this works.


After a long day at work, you need fast food and that’s what you get with fresh fruit, fruit juice, a crispy salad or a tasty portion of vegetables! What’s more, not only are they a quick and tasty treat, they also enhance your mood! However, to preserve the vitamins and nutrients that they contain, you’ll need to have the right storage environment at home. Food’s shelf life is determined firstly by its freshness, and then by the temperature and humidity at which it’s stored. For this reason Liebherr has developed its BioFresh technology, which stores food at just above 0°C, with the support of high-precision electronics.

Targeted humidity for specific Foods

Humidity regulation in the BioFresh drawers makes it possible to individually set the humidity in DrySafes or HydroSafes. DrySafes with low humidity (dry climate) are ideal for storing meat, fish and dairy products.


Humidity regulation means you can individually set the humidity levels in the BioFresh safes.
