A refrigerator is an unnecessary, large appliance in a home and is also known as"Food Organizer".It is a rare storage space in home life.
Everyone has a refrigerator at home, but not everyone will use it:What foods should not be refrigerated? How long do different foods last in the fridge? What are the different storage locations in the refrigerator? Do you know all of this? In this issue, let's talk about decoration to share the practical guide that most people can't answer, so that everyone can say that it is correctOpen With
Before we understand which foods should not be refrigerated, let's first understand why we should refrigerate them, so that we can understand more comprehensively.
Before food is refrigerated, that is, at about 0 degrees Celsius, microorganisms usually stop or slow down the rate of reproduction, and can also slow down the movement of molecules, which is not easy to collide with each other and react. Many of the reactions that make food spoil and nutrients are lost will also slow down as the temperature drops.
After refrigeration, many foods can increase the freshness of food, which is more conducive to food storage and ensures that food is not wasted.
Next, let's talk about which foods should not be placed in the refrigerator area, which is also the refrigeration function of the refrigerator to ensure that you do not make the wrong one.
Chocolate, sweet potato, banana, mango, durian. If these ingredients are left in the refrigerator for a long time, frostbite will occur, and the texture will become rough, due to the change in the crystalline form of cocoa butter, although there are no nutritional and safety issues, but the enjoyment when eating is far from good.
Tomatoes, unripe fruitsIf this kind of food is directly placed in the valve room of the refrigerator, the genes related to the production of aromatic substances in tomatoes will be "frozen" at low temperatures, resulting in a great reduction in their flavor.
Pasteurized cooked meat, soy products, tomato paste, mustard sauce, sand tea sauce, condiments, fruits and vegetables, dried fish, shrimp skin, sea rice, sesame paste. These foods are suitable for being placed in the refrigerator room, and it is also to ensure that the flavor and texture will not be significantly reduced.
The refrigerator is not"Safe".There are also their own foods to put in"Shelf life".Therefore, it is necessary to store the food according to its shelf life, so that you can be surprised that the food has spoiled because it has been stored for a long time.
1.Meat
For meat and marinated cooked food, it is safe to store in the refrigerator freezer2--3 daystime.
If you put it in the freezer, generally speaking, beef should not exceed 3 months, fish should not exceed 6 months, animal offal should not exceed 4 months, and fish with less fat should not exceed 6 months.
2.Eggs
Fresh eggs can generally be stored for 1-2 months, hard-boiled eggs can generally be guaranteed for about 1 week, and egg yolks and egg whites can generally be stored for about 2 days.
3.Dairy products
Milk can be stored for 5-6 days when refrigerated, and yogurt for 7-10 days longer. If the milk is opened, it should not be stored for more than 24 hours, and it cannot be eaten after the time.
4.Vegetables
Root vegetables such as radishes are generally stored for 1-2 weeks. Cauliflower, beans, and green peppers can be stored for about 5 days at most. Onions, garlic and potatoes should not be stored in the refrigerator.
5.Fruits
For most fruits, it can be stored for about 3-15 days, and the specific ones can be classified according to the type of fruit.
But for fruits that have been cut, the shelf life should not exceed 24 hours, and once it is exceeded, it is not recommended to eat it.
If you want to make this food as fresh as possible, in addition to remembering the refrigeration time, you must also learn to place it correctly so that it can be made fresher.
1.Vegetables
Remember not to wash the vegetables with water before putting them in the refrigerator, and put them directly into a perforated plastic bag and store them in the refrigerator.
This makes it better and longer-lasting. At the same time, be careful not to get close to the inner wall of the refrigerator to avoid frostbite.
2.Fruits
Grapes, apples, strawberries, etc., such thing"Cooked".It is recommended to put the fruit in a plastic bag to prevent water loss, and then put it in the refrigerator.
Kiwi, persimmon, etc"Late ripening".It is recommended to keep the fruit at room temperature before considering whether to put it in the refrigerator.
3.Meat
Meat floss, jerky, dried meat, ham sausage, canned food, etc., can be stored at room temperature, and put in the refrigerator after opening.
It is important to keep in mind that seafood and livestock and poultry meat should be separated and not put together, so as to avoid the taste of skewers.
If you want to store the food in the refrigerator with better freshness, you must be inseparable from the following "cold knowledge", because it is very critical and alsoUse the "right" refrigeratorImportant steps.
1.The refrigerator is only seven points full
Although the refrigerator is used as a food storage device in home life, the storage is also limited, and it is necessary to ensure the freshness of the food on the basis of storage, so that it belongs to the use of "right".
Normally, the refrigerator is put in the refrigeratorSix or seven points fullIt is the best to ensure that there is as much space between the food or containers as possible, so that the cold air circulates and every corner of the refrigerator reaches the ideal temperature value.
2.Cool hot food before putting it in the refrigerator
Whether it's a refrigerated or frozen area, if you want to put food in, you should cool it down before putting it in, so as to ensure that the internal temperature of the refrigerator remains stable and low without rising too much.
Don't underestimate this step, just do it rightSave money on your electricity billFood is also less likely to spoil, which is an important rule for "using the right" refrigerator.
3.The freshness temperature is controlled below 4°C
In general, the optimal growth temperature of microorganisms is mostly between 5 °C and 57 °C, which is calledHazardous Temperature Range.
Therefore, the freshness temperature of the refrigerator should be lower than this temperature value, in general, set at:4 °C or lessFood should be avoided in this temperature zone to prevent the growth of microorganisms.
4.Avoid storing expired food
Clean up the food in the refrigerator regularly, and eat it at the best time to make the food taste the best.
When taking food from the refrigerator, cultivate"First in, first out".Try to take the food that was stored earlier first, and check the shelf life of the food regularly to avoid food expiration.
There was a sudden power outage at home, and how long the food in the refrigerator could be guaranteed, I believe this is something that many people want to know.
In simple terms, if the power outage is timeWithin 4 hours, and the refrigerator door is closed and not opened, then the food in the refrigerator can be eaten, but the shelf life should be halved, such as the original food that can be stored for 7 days, it should be eaten within 3 days.
Once the power goes outMore than 4 hoursAll the food in the refrigerator cannot be stored effectively, so it is recommended to dispose of it on the same day.
