BioFresh keeps food fresh for longer

Storing food in tropical climates is often a challenge. BioFresh is Liebherr’s patented refrigeration technology that’s designed to keep fruit, vegetables, fish, meat and dairy products fresher for much longer. It takes into account the fact that different storage conditions are necessary to optimally store different types of food, and so BioFresh offers a tailored storage climate for maximum freshness.

The interplay of temperature and humidity

Both air circulation and temperature can be adjusted in the BioFresh safes.

Both air circulation and temperature can be adjusted in the BioFresh safes.

A tropical climate means high ambient temperatures with high levels of humidity – conditions under which food spoils extremely quickly. BioFresh technology was developed based on the fact that food stays fresh for longest when stored at a temperature just above freezing point. The BioFresh drawers therefore offer a carefully maintained temperature of just above 0 °C, which is far lower than a normal refrigerator compartment temperature.

However, an optimum temperature alone is not enough to preserve freshness: fruits and vegetables also require moisture to remain crisp, whereas cheese and dried fruits keep best when stored in dry conditions. To take account of this, the humidity in the BioFresh drawers can be adjusted using a slider control to create either a HydroSafe or a DrySafe. The drawers act as freshness safes, which can be set as desired. BioFresh transforms refrigerators into versatile storage spaces, in which the widest range of foods can be stored under ideal conditions.

Multiple climate zones in one appliance

If the BioFresh-Safe is set to HydroSafe, the humidity increases to keep unpackaged fruit, vegetables and salad products fresh and crisp for longer. Precision electronics carefully maintain the temperature at just above 0 °C, preventing any undesired freezing of the food, even at higher humidity levels.

When the vents are opened, the humidity falls, and the BioFresh-Safe becomes a DrySafe. This lower humidity is ideal for storing fish, meat, dairy products and dried fruit. When stored packaged in this comparatively dry climate, these foods retain their flavour for far longer than in a conventional refrigerator compartment – cheese, for example, keeps well for up to 100 days.

Incidentally: Temperatures of just over 0 °C are ideal for storing fresh food but are usually too cold for immediate consumption of the food. Cheese only develops its full flavour at room temperature, and fruit tastes better when it’s not too cold. Also, meat should be allowed to come up to room temperature before being cooked. Therefore store food in the refrigerator at a constantly cool temperature, but remove it well before eating or cooking it.

Customised food storage with BioFresh

The carefully balanced interplay of humidity and temperature is vital for successful long-term storage with good nutrient preservation. In this regard, different types of food have very different requirements: tropical fruits grow in climates with high humidity levels, cheese develops its full flavour in cool, dry caves, and fish requires constant storage at freezing point. With its flexibly regulated safes, BioFresh can provide optimum storage conditions for each food category.

Customised food storage with BioFresh

  • Fruit
    Fruit tastes best when fully ripe, and fruit from the tropics grows in a humid climate where the sunshine and heat boost its flavour. To preserve the fruit’s flavour and consistency after harvest, cooling alone is not enough –a high humidity level is also essential. Humidity can be regulated in the HydroSafe and, as a result, sensitive tropical fruits can be kept fresh for much longer.

  • Meat and dairy products
    Meat products, fresh mutton, poultry and kheema (minced meat) have very specific storage requirements in terms of temperature and humidity. The BioFresh DrySafe offers them the ideal environment: low humidity and a temperature of just above freezing, which significantly reduces the activity of microorganisms and so greatly extends product shelf life. DrySafe conditions are also ideal for milk, cheese and paneer (cottage cheese).

    The high water content of vegetables means that they need to be stored at high humidity levels. The BioFresh HydroSafe creates the optimum storage environment and uses precision electronics to maintain a constant temperature of just over 0 °C. HydroSafe conditions prevent any undesired freezing of the food, prevent it from dehydrating, and help to preserve most of its valuable nutrients.

  • Fish
    Retailers store fish and seafood on ice for good reason: their ideal storage temperature is at freezing point. Fish has particularly demanding storage requirements, and must be kept at an uninterrupted low temperature. Set to precisely 0 °C, the BioFresh-Safe is perfect for storing fish and, when set to DrySafe conditions, it ensures that bhakur, barramundi and crab all stay fresh in the refrigerator for much longer.
