Many housewives are accustomed to filling the refrigerator compartment with all the contents of the packages immediately after returning from the store. Intuitively, it seems that cold will preserve the freshness of absolutely any food, prevent the growth of bacteria and extend the shelf life. However, this is a common misconception that can lead to rapid spoilage of products, changes in their taste and even loss of beneficial properties.
Modern refrigerators create a specific damp and cold environment, which is destructive for some categories of food. Exotic fruits, root vegetables and bakery products behave unpredictably in such conditions. In this article, we will take a closer look at why some products should absolutely not be sent to the refrigerator shelves, and where exactly they are best stored to maximize quality.
Understanding the principles of thermodynamics and biochemistry of food will help you not only save money, but also enjoy truly delicious food. You will be surprised to learn that the habit of storing tomatoes or potatoes in the cold deprives you of some of the vitamins and flavor. Let's figure out what mistakes we make most often.
Tomatoes and loss of taste
Tomatoes are one of the most popular products, which are most often mistakenly sent to the refrigerator. In fact, low temperature destroys the cell walls of the fruit, making the pulp mealy and loose. Aromatic compoundsResponsible for the very smell of a ripe tomato, under the influence of cold they stop being produced.
If you take out a chilled tomato, it will appear to you tasteless and watery. Tomatoes need room temperature to fully ripen and maintain texture. The only exceptions are already cut fruits, which really need to be covered and put on the shelf, but it is better to eat them within 24 hours.
Interestingly, in the Mediterranean countries, where the best are grown varieties, they are never hidden in the cold. They know: cold kills the soul of a vegetable. Therefore, when buying beautiful red fruits, leave them on the kitchen counter in the fruit basket.
Potatoes, starch and low temperatures
Root vegetables such as potatoes require special storage conditions that differ from the climate inside the refrigerator. At temperatures below +7 degrees Celsius starch, contained in the tubers, begins to actively transform into sugar. This leads to the appearance of an unpleasant sweetish taste and a change in the color of the pulp during cooking.
In addition, high humidity in the refrigerator provokes the sprouting of eyes and the development of mold. Potatoes love darkness, coolness (but not cold!) and dryness. The ideal place would be a cellar, basement or a special box in the pantry, where the temperature is around +10...+15 degrees.
⚠️ Attention: Never store potatoes together with onions. They release gases that speed up each other's deterioration. Separate them or store them in different containers.
If you do put the potatoes in the refrigerator, let them sit at room temperature for several hours before cooking. This will partially restore the starch structure, although it will not be possible to completely restore the original taste. It is better to immediately determine the correct storage location.
Onion stocks and humidity
Onions are another product that is absolutely not friendly to the refrigerator if it is whole and unpeeled. Excessive moisture causes the husk to become soggy, and the bulb itself becomes soft and begins to rot. In a dry state, onions can be stored for months, maintaining their phytoncidal properties.
It is better to store onions in mesh bags, stockings or wicker baskets that provide free air circulation. It is important that the room is well ventilated. The lack of light also plays a role, since in the light onions can begin to germinate ahead of time.
The situation changes if the onion is already peeled or chopped. In this form, it must be placed in an airtight container and refrigerated, but used within 1-2 days. Whole heads should remain at room temperature in a dry place.
Bread products and the staling process
Many people believe that the refrigerator is the best place for bread so that it does not go moldy. Indeed, cold slows down the growth of mold, but it also speeds up the process starch retrogradation. In simple words, bread in the refrigerator goes stale 3-6 times faster than at room temperature.
Moisture from the crumb migrates into the crust, making it rubbery, and the crumb itself becomes dry and crumbly. If you need to keep your bread fresh for more than 2-3 days, it is best to freeze it. Freezing stops all biochemical processes, and after defrosting the bread will be as fresh.
How to freeze bread correctly?
Cut the bread into slices, wrap in cling film or foil and put in the freezer. If necessary, take out the required number of slices and heat them in a toaster.
Bread bins made of wood or ceramics with holes for ventilation are ideal for daily storage. They maintain an optimal microclimate, preventing the bread from drying out or becoming damp. Plastic bags are also undesirable, since bread in them quickly “suffocates” and becomes moldy.
Honey, oil and crystallization
Natural honey is a product that can be stored for centuries without loss of properties, but only under the right conditions. In the refrigerator, honey quickly crystallizes and sugars, turning into a solid lump that is difficult to remove from the jar. In addition, cold can cause the product to separate.
Butter also requires attention. While we often keep it in the refrigerator, for daily use it's best to leave a small piece in a butter dish at room temperature (if you plan to eat it 2-3 days in advance). Cold butter is hard and difficult to spread, losing some of its aromatic properties.
However, if you buy butter for future use, it is better to store it in the freezer, wrapped in foil. In the main compartment of the refrigerator, oil easily absorbs foreign odors, since fat is an excellent sorbent.
| Product | Reaction to cold | Optimal place |
|---|---|---|
| Honey | Crystallization, loss aroma | Kitchen cabinet, dark place |
| Olive oil | Hardening, cloudiness | Cool place away from light |
| Avocado (whole) | Stopping ripening, blackening | Room temperature (before ripening) |
| Bananas | Blackening of peel, stopping ripening | Room temperature |
Tropical fruits: bananas, mangoes, papaya
Fruits brought from warm countries are not genetically adapted to low temperatures. When placed in the refrigerator, a protective mechanism is activated: the peel quickly turns black and the ripening process stops. As a result, you get a fruit that is blackened on the outside and hard, unripe on the inside.
Bananas they instantly darken in the cold. The enzymes responsible for ripening stop working, and the fruit may rot without becoming sweet. Mangoes and papaya also require heat to ripen. Only after they become soft and fragrant can they (but not necessarily) be refrigerated for a short time before serving.
⚠️ Attention: If you bought hard avocados, do not put them in the refrigerator immediately. Let them sit at room temperature for 2-4 days until softened, otherwise they will remain “woody.”
An exception may be already cut tropical fruits. They, of course, need to be stored in the refrigerator in a closed container so that they do not dry out and become a habitat for bacteria. But whole fruits should remain in the fruit bowl on the table.
Chocolate, coffee and odor absorption
Chocolate is a capricious product. In the refrigerator, it becomes covered with a white coating called “fat bloom.” This occurs due to changes in temperature and humidity: cocoa butter comes to the surface and hardens. This does not spoil the taste, but the aesthetic appearance suffers, and the texture becomes grainy.
Coffee beans or ground coffee also does not like being next to other products in the refrigerator. Coffee is powerful absorbent properties and instantly absorbs the odors of meat, fish or vegetables lying nearby. As a result, your morning drink may acquire an unpleasant foreign taste.
☑️ Checking storage conditions
It is better to store coffee and chocolate in airtight jars in the kitchen cabinet. If the apartment is very hot (above +25 degrees), the chocolate can be put in the refrigerator, but only in a tightly closed container and on the warmest shelf (usually the door), after allowing it to cool to room temperature.
Eggs and the refrigerator door
Although eggs are traditionally stored in the refrigerator, where they are placed is critical. The door is the most unsuitable place for them, since there are constant temperature changes when opening. This can lead to spoilage of the product and the development of salmonellosis.
In addition, many egg manufacturers do not recommend washing them before storage, since water washes away the protective film and the pores of the shell open to bacteria. In European stores, eggs are often just lying on the shelves, and there is a logic to this: at a stable room temperature they are stored for up to 25 days.
If you are still used to storing eggs in the cold, put them in the main compartment on the middle shelf, and not in the door. And try not to wash them until just before cooking. This will help keep them fresh longer.
How to check the freshness of an egg?
Dip the egg in a glass of water. If it sank, it’s fresh; if it floats up with a blunt end, it’s old; if it floats in the middle, it needs to be used as soon as possible.
Following these simple rules will allow you to significantly reduce the amount of food thrown away. You will notice that the food has become tastier, and you have to make purchases less often, since supplies no longer spoil.
Can watermelon be stored in the refrigerator?
It is better to store a whole watermelon at room temperature so that it retains its antioxidants. A cut watermelon must be put in the refrigerator, tightly wrapped in film, but for no more than 2 days.
Why can’t you store mushrooms in a plastic bag?
Mushrooms are a living organism that breathes. In polyethylene they suffocate and become covered with mucus. For refrigerator storage (short-term), use a paper bag or glass container.
How long does opened wine last in the refrigerator?
Opened red or white wine can be stored in the refrigerator for 3-5 days, tightly corked. However, the taste will gradually deteriorate. Fortified wines can last longer.
Is it harmful to store baby food in the refrigerator after opening?
Puree in glass jars after opening can be stored in the refrigerator for no more than 24 hours. Pediatricians recommend eating the contents of an open jar on the same day to avoid bacterial growth.
