The freshness zone (or “zero chamber”) is a special compartment in modern refrigerators where the temperature is maintained around 0...+1°C and high humidity. This microclimate is ideal for maintaining the freshness of perishable foods without freezing. But not everyone knows what can and cannot be put in this compartment, and improper use leads to rapid spoilage of food or even the risk of food poisoning.
In this article we will analyze in detail which products are optimally stored in the freshness zone, how to place them correctly and what mistakes users most often make. You will learn why milk and sausage are not always suitable for this compartment, as well as how to prolong the freshness of herbs, meat and fish without losing their taste. We will pay special attention to the nuances for different models of refrigerators - from budget ATLANT to premium Liebherr.
What is the freshness zone and how does it work
The freshness zone is a compartment with a temperature close to zero, but without ice formation. Unlike the main chamber (+4...+6°C), the growth of bacteria slows down here, but does not stop completely. This allows you to store food longer than in conventional compartments, but without the freezing effect.
In most refrigerators, the freshness zone is implemented as:
- 🧊 Drawer with adjustable humidity (for example, in models Samsung RB37J5240SA or Bosch KAN92VI30R).
- 📦 Separate shelf with ventilation and moisture removal (typical for Liebherr CBPesf 4043).
- 🔄 Hybrid compartmentwhich can be switched between the "dry zone" (for meat) and "wet zone" (for vegetables) modes.
It is important to understand that the temperature is in the freshness zone should not fall below -1°C, otherwise the products will begin to freeze, losing texture and taste. In some refrigerators (for example, LG InstaView Door-in-Doorthis compartment is equipped with a humidity sensor that automatically maintains optimal conditions.
What products can be stored in the freshness zone
The freshness zone is intended for products that quickly spoil at room temperature, but do not require deep freezing. Here is what you can put here:
- 🥩 Fresh meat and poultry (up to 3-5 days). pork, chicken - 0...+1°C.
- 🐟 Fish and seafood (up to 2-3 days). Especially useful for salmon, trout, shrimp.
- 🧀 Soft cheeses (brie, Camembert, ricotta) - up to 7 days. It is better to store hard cheeses in the main compartment.
- 🥬 Greens (parsley, dill, basil) - up to 10 days if packed in a container with a paper towel.
- 🍓 Berries (strawberries, raspberries, blueberries) - up to 5-7 days without mold.
- 🥚 Eggs in the shell (up to 3 weeks), but only if they are not washed (washed ones are stored worse).
Also well preserved in the freshness zone sausages (boiled sausage, frankfurters) - up to 5 days, and dairy products (cottage cheese, sour cream) - up to 7 days However milk and kefir it is better to keep in the main compartment: at temperature. near zero they can separate.
What NOT to store in the fresh zone
Some foods spoil faster or lose their taste at temperatures around zero. Here's what you shouldn't put in this compartment:
- 🍌 Bananas, pineapples, mango —at low temperatures they turn black and become black. soft.
- 🥔 Potatoes and sweet potatoes —starch is converted into sugar, a sweetish taste appears.
- 🧅 Onions and garlic —become soft and sprout.
- 🍯 Honey, jam, sauces —can become candied or flaky.
- 🍞 Bread and pastries —stale 2-3 times faster than at room temperature.
- 🥛 Pasteurized milk - may curdle due to unstable temperature.
It is also not recommended to store here canned food (even after opening), alcohol (except for non-alcoholic beer) and spices - they lose their aroma. If you like to keep them in the refrigerator chocolatethen the freshness zone is also not suitable for it: it will become covered with a white coating.
⚠️ Attention: If raw meat or fish are stored in the freshness zone, they must be packaged in sealed containers or vacuum bags. Otherwise, juices may leak and contaminate other products with bacteria. (for example, Salmonella or Listeria).
Table of shelf life of products in the freshness zone
To make it easier for you to navigate, we have compiled a table with the recommended shelf life of the most popular products:
| Product | Shelf life | Conditions |
|---|---|---|
| Beef (fresh) | 3–5 days | In a vacuum package or container with paper towel |
| Chicken fillet | 2–3 days | Packed in cling film, without contact with other products |
| Salmon, trout | 1–2 day | Rinse, dry with a paper towel, store in a closed container |
| Cottage cheese | 5–7 days | In the original packaging or airtight container |
| Greens (parsley, cilantro) | 7–10 days | Packed in paper or a container with holes for ventilation |
| Berries (strawberries, raspberries) | 5–7 days | Not washed, in a container with a paper towel on the bottom |
Please note: the timing may vary depending on initial freshness of the product and accurate temperature for example, in models with a system No Frost (for example, Indesit ITF 118 Wthe humidity in the freshness zone is lower, so meat and fish are stored for 1–2 days less.
How to properly package products for the freshness zone
Even in ideal conditions, food quickly spoils if incorrectly packaged. Here are the basic rules:
- Meat and fish store in vacuum packages or sealed containers. If there is no vacuum sealer, wrap the product in cling film, removing as much air as possible.
- Keep greens and vegetables pack in paper towels or perforated bags. This prevents the accumulation of condensation.
- Dairy products (cottage cheese, sour cream) in original packaging, but if it is damaged, transfer it to a glass or plastic container with a lid.
- Berries Do not wash before storage! Humidity accelerates the growth of mold. Rinse them immediately before use.
For convenience, you can use reusable silicone lids or containers with a valve (for example, from Tupperware or Lock&Lock). They allow you to regulate air access and prevent the mixing of odors.

Typical mistakes when using the freshness zone
Many users make the same mistakes, which cause food to spoil faster. Here are the most common:
- 🚫 Compartment overload. If the box is packed to capacity, air does not circulate and the temperature is distributed unevenly.
- 🚫 Storing food without packaging. Juices from meat or fish may drip onto other foods, causing cross-contamination.
- 🚫 Ignoring the temperature mode. If the “Vacation” or “Eco” mode is turned on in the refrigerator, the freshness zone can heat up to +3...+5°C.
- 🚫 Storing hot foods. Before putting food in the freshness zone, it must be cooled to room temperature.
- 🚫 Long-term storage of semi-finished products. It is better to freeze dumplings, cutlets or minced meat rather than keep them in the freshness zone for longer than 2 days.
Another common mistake is irregular cleaning. The freshness area must be washed at least once every 2 weeks, even if it looks clean on the outside. In a humid environment, bacteria quickly multiply, which can cause an unpleasant odor.
⚠️ Attention: If a persistent odor appears in the freshness area, do not mask it with fragrances! This is a sign that bacteria has accumulated somewhere. You need to remove all the products, rinse the compartment with a soda solution (1 tablespoon per 1 liter of water) and dry.
Features of the freshness zone in refrigerators of different brands
Not all freshness zones are the same. Depending on the refrigerator model, they may differ in temperature, humidity and even location. Let's consider the nuances for popular brands:
- 🔹 Liebherr: Models with the system BioFresh have separate compartments for meat/fish (DrySafe) and fruits/vegetables (HydroSafe). The temperature here remains stably at 0°C.
- 🔹 Samsung: The zone CoolSelect Zone can operate in three modes: “Meat/fish” (+1°C), “Greens/vegetables” (+3°C) and “Drinks” (+5°C). The mode is selected manually.
- 🔹 Bosch: In refrigerators with VitaFresh humidity is adjusted automatically, but the temperature depends on the general mode of the refrigerator. When activated
SuperCoolit can drop to -2°C - this is harmful for greenery! - 🔹 ATLANT: The freshness zone here is often combined with the zero chamber. If you see the designation "0° Zone", this means that the compartment can be used for both cooling and short-term freezing.
- 🔹 LG: In models with DoorCooling+ the freshness zone is located on the door. This is convenient, but the temperature here is less stable due to frequent opening.
If you have an electronically controlled refrigerator (for example, Samsung Family Hub), check the freshness zone settings in the menu. In some models, you can set the target temperature with an accuracy of a degree.
How to check the real temperature in the freshness zone?
Place a household thermometer (for example, Xiaomi Mijia Bluetooth) in the compartment for 12 hours. If the temperature is above +1°C, adjust the refrigerator settings or check the door seals.
FAQ: Frequently asked questions about the freshness zone
Is it possible to store ready-made dishes (soups, cereals) in the freshness zone?
Yes, but not longer than 2-3 days. It is better to store prepared dishes in airtight containers and place them on the top shelf of the main chamber. In the freshness zone, they can become overcooled, which will worsen the taste.
Why does ice form in the freshness zone?
This happens due to two reasons: 1) a malfunction of the defrosting system (needs repair), 2) the temperature is too low (check the settings). Normally, ice should not appear.
Can medicines or vitamins be stored here?
No. Most medications require a temperature of +2...+8°C (main chamber) or room temperature. The fresh zone is too cold and damp for them.
How often should you defrost the fresh zone?
If your refrigerator has a system No Frost, there is no need to defrost. In other cases - once every 3-6 months, depending on the intensity of use.
Can mushrooms be stored in the freshness zone?
Yes, but not longer than 3 days. It is better to keep mushrooms in a paper bag or container with holes. Do not wash them before storing!
