The freshness zone is a separate compartment in the refrigerator, which often raises questions even among experienced housewives. Many people mistakenly consider it a “zero chamber” or just an additional shelf, but in fact it is a unique space with a special microclimate. The temperature is maintained here around 0°C and high humidity - ideal conditions for products that quickly spoil in the main chamber, but are not suitable for freezing.
Why do manufacturers Samsung, LG, Bosch and Liebherr pay such attention to this compartment? The fact is that proper use of the freshness zone extends the shelf life of meat, fish, herbs and dairy products by 1.5–2 times without loss of taste and nutritional properties. However, not all products are well preserved there - some, on the contrary, will spoil faster. In this article, we will look at what products should absolutely not be placed in the freshness zone next to raw meathow to set the temperature and what mistakes shorten the shelf life of food.
What is the freshness zone and how does it work
Freshness zone (its also called Fresh Zone, BioFresh or CoolSelect Zone) - it is a sealed box or compartment with a separate cooling system. Unlike the main chamber, where the temperature ranges from +2°C to +6°C, a stable humidity level is maintained here with humidity up to 90%. This mode slows down the growth of bacteria, but does not stop them completely (unlike the freezer). 0°C with humidity up to 90%. This mode slows down the growth of bacteria, but does not stop them completely (unlike the freezer).
Technically, there are two types of freshness zone:
- 🔹 With dry cooling — for meat, fish and cheeses (humidity ~50%). Fans evenly distribute cold air, preventing the formation of condensation.
- 💧 With high humidity — for vegetables, fruits and herbs (humidity ~90%). There are often special filters that absorb ethylene (a gas that accelerates ripening).
In premium refrigerators (for example, Liebherr BioFresh or Samsung Twin Cooling Plus) the freshness zone is equipped with a separate compressor and an air filtration system. This allows you to avoid mixing odors and maintain a stable temperature even with frequent opening of the door.
What products can and should be stored in the freshness zone
The main rule: products that are placed in the freshness zone spoil at room temperature, but are not intended for freezing. Here is a complete list of what is well preserved there:
- 🥩 Raw meat (beef, pork, lamb) - up to 5-7 days (in a regular compartment - maximum 2-3 days).
- 🐟 Fish and seafood - up to 3-4 days (in the main chamber - no more than a day).
- 🧀 Cheeses (especially soft and moldy) - up to 2-3 weeks without drying.
- 🥛 Dairy products: cottage cheese, sour cream, yoghurts without sugar - 3-5 days longer than in the main chamber.
- 🥬 Greens (parsley, dill, basil) - up to 10-14 days, if packed in a container with a paper towel.
- 🍓 Berries (strawberries, raspberries, blackberries) - up to 5-7 days without loss of shape.
- 🥕 Vegetables: carrots, celery, asparagus - up to 2-3 weeks.
Important: products in freshness zone must be packaged. Use vacuum bags or containers with a lid for meats and fish, paper towels for greens, and parchment paper for cheeses. This prevents the exchange of odors and drying out.
What cannot be stored in the freshness zone: 5 dangerous mistakes
Not all products tolerate temperatures around 0°C well. Here's what to strongly not recommended put in this compartment:
- 🍌 Bananas, avocado, mango - at 0°C they stop ripening and begin to rot from the inside.
- 🥔 Potatoes and onions - the starch in them turns into sugar, and the onion becomes slimy.
- 🍅 Tomatoes - lose their taste and become mealy.
- 🧂 Spices and dry products (flour, cereals) - become damp and clump.
- 🍷 Alcohol (wine, beer) - may become cloudy or change the taste.
Another common mistake is store ready-made dishes in the freshness zone (soups, cereals, salads). At 0°C they do not spoil, but quickly lose their taste. For example, borscht will become watery and pasta will become rubbery. For ready-made food, it is better to use the main chamber (+2...+4°C).
⚠️ Attention: Never put in the freshness zone defrosted products (meat, fish, semi-finished products). After defrosting, they should be cooked immediately or stored in the main chamber for no longer than a day. At 0°C, bacteria actively multiply on the surface of such products.
Optimal temperature and freshness zone settings
In most refrigerators, the freshness zone has temperature control. Optimal values depend on the type of product:
| Type of product | Recommended temperature | Maximum shelf life |
|---|---|---|
| Meat, poultry, fish | -1…+1°C | 5–7 days |
| Dairy products (cottage cheese, sour cream) | +1…+2°C | 7–10 days |
| Vegetables, herbs, berries | +2…+3°C | 1–3 weeks |
| Hard cheeses | +2…+4°C | up to 1 month |
| Sausages, frankfurters | +1…+3°C | 5–7 days |
How to adjust the temperature:
- In refrigerators Bosch i Siemens the freshness zone is adjusted by a slider inside the compartment (usually there are marks
Meat/FishandVegetables). - In models Samsung and LG setting occurs through the control panel on the door (look for the button
FRESH ZONEorCOOL SELECT). - In Liebherr the temperature of the freshness zone is tied to the main chamber: if the refrigerator has +4°C, then in BioFresh 0°C will be automatically maintained.
⚠️ Attention: If the freshness zone in your refrigerator is not is equipped with a separate compressor (for example, in budget models Indesit or Atlant), its temperature depends on the main chamber. In this case, do not store perishable products there for longer than 2-3 days.

How to properly package products for the freshness zone
Even at ideal temperatures, incorrect packaging reduces the shelf life of products by 2-3 times. Here are the basic rules:
- 🥩 Meat and fish: vacuum bags or containers with a lid. no - wrap in cling film, removing all the air.
- 🧀 Cheeses: parchment paper + plastic bag with holes (so that the cheese “breathes” but does not dry out).
- 🥬 Greens: rinse, dry, wrap in a paper towel and place in a container.
- 🍓 Berries: Do not wash before storage! Place in a container in one layer, cover with a paper towel.
Avoid these mistakes:
- ❌ Storing meat in original packaging from the supermarket (it is not airtight).
- ❌ Using foil to greenery (it interferes with air circulation).
- ❌ Overfilling of containers (products should lie freely, not wrinkle).
What to do if the products in the freshness zone are covered with ice?
This is a sign of improper air circulation. Defrost the refrigerator, check the door seals and do not put hot food in. If the problem recurs, there may be a malfunction of the fan or temperature sensor.
Storage life of products in the freshness zone: table
Even under ideal conditions, products are not stored forever. Here are the real terms for the most popular categories:
| Product | Shelf life in the freshness zone | Life in the main chamber |
|---|---|---|
| Fresh meat (beef, pork) | 5–7 days | 2–3 days |
| Chicken, turkey | 3–5 days | 1–2 days |
| Fish (fillet) | 3–4 days | 1 day |
| Shrimp, mussels | 2–3 days | 1 day |
| Cottage cheese, sour cream | 7–10 days | 3–5 days |
| Greens (parsley, dill) | 10–14 days | 3–5 days |
| Berries (strawberries, raspberries) | 5–7 days | 2–3 days |
Please note: the terms are indicated for fresh high-quality products quality. If meat or fish has already begun to spoil, the freshness zone will not save the situation - it only slows down, but does not stop the rotting process.
Cleaning and caring for the freshness zone: step-by-step instructions
The freshness zone requires more careful care than the main chamber. Here's how to clean it correctly:
- Defrosting. Turn off the refrigerator, take out all the food and let the ice (if any) melt naturally. Do not use a hairdryer or hot water!
- Washing. Rinse all surfaces with warm water and baking soda (2 tablespoons per 1 liter of water) or a special product for refrigerators. Avoid aggressive chemicals.
- Disinfection. Wipe the walls and shelves with a weak solution of vinegar (1:1 with water) - this will kill bacteria and eliminate odors.
- Drying. Wipe all surfaces dry soft towel. The humidity inside should be minimal before turning on.
- Checking the seals. Make sure that the rubber bands on the door are intact and fit tightly. If they are cracked, replace them.
It is recommended to clean the freshness zone every 2-3 monthseven if visually it seems clean. In a humid environment, mold and bacteria quickly multiply, which can spoil food.
⚠️ Attention: If a persistent odor appears in the freshness zone that cannot be removed by washing, place an open pack of soda or activated carbon for 12 hours. Do not use flavorings - they can be absorbed into the food.
FAQ: Frequently asked questions about the freshness zone
Is it possible to store defrosted products in the freshness zone?
No. Thawed meat, fish or semi-finished products should be cooked immediately or stored in the main chamber for no longer than a day. In the freshness zone at 0°C, bacteria actively multiply on their surface, which can lead to food poisoning.
Why does ice form in the freshness zone?
Ice appears due to two reasons: 1) a leaky door (check the seals); 2) high humidity + frequent openings. Try to reduce the humidity (if your model has an adjustment) and do not put hot foods.
Is it possible to store ready-made dishes in the freshness zone?
It is possible, but not advisable. At 0°C, prepared food (soups, cereals, salads) does not spoil, but loses taste and texture. For example, borscht will become watery and pasta will become rubbery. For ready-made dishes, it is better to use the main chamber (+2...+4°C).
How often do you need to defrost the freshness zone?
If your model has a No Frost system, you do not need to defrost the freshness zone. In other cases - every 3-6 months, depending on the intensity of use. Watch out for ice formation: if its layer exceeds 5 mm, it’s time to clean it.
Can I turn off the freshness zone if I don’t use it?
Yes, in most refrigerators this function can be turned off through the control panel (usually there is a button FRESH ZONE OFF). This will save energy. However, in some models (for example, Liebherr BioFresh), the freshness zone works constantly and does not turn off.
