In modern homes, refrigerators have become one of the indispensable appliances. It helps us to preserve food for a long time, ensuring that the ingredients are fresh and hygienic. However, many people do not know much about the temperature settings in the refrigerator compartment, resulting in unsatisfactory food preservation. So, how many degrees should the refrigerator be refrigerated?This article will answer this question in detail for you and take you through the importance and precautions of refrigerator temperature setting.
1. Overview of answers
The temperature of the refrigerator compartment should generally be set between 4-8 degrees Celsius, which can not only inhibit the growth of bacteria, but also maintain the fresh taste of food. There may be slight differences between different brands of refrigerators, but they are generally in this range. It is important to note that the lower the temperature setting in the refrigerator compartment, the better, and too low a temperature may cause frostbite of the food, affecting the taste and nutritional value.
2. Detailed description
Why choose 4-8 degrees Celsius?
The temperature of the refrigerator compartment is set between 4-8 degrees Celsius, mainly because this temperature range is able to effectively inhibit bacterial reproduction. Bacteria multiply at lower temperatures at a slower rate, which prolongs the shelf life of food. At the same time, this temperature range does not freeze the food too quickly, maintaining the original taste and nutritional value of the food.
The effect of setting the temperature too low
While low temperatures inhibit bacterial growth, if the temperature in the refrigerator compartment is set too low, it can cause frostbite to food. Ice crystals can appear on the surface of frostbitten food, causing cells to rupture, which can affect the taste and nutritional value of the food. In addition, some temperature-sensitive foods, such as vegetables and fruits, may accelerate decay at too low temperatures.
The effect of setting the temperature too high
If the temperature of the refrigerator compartment is set too high, it will not be able to effectively inhibit the growth of bacteria and shorten the shelf life of food. Excessively high temperatures can also cause food to spoil, develop odors, and even cause food safety issues.
3. Precautions for setting the refrigeration temperature of the refrigerator
Adjust the temperature according to the season
The temperature settings in the refrigerator compartment should be adjusted according to the season. In summer, when the room temperature is high, the temperature of the refrigerator can be set on a lower setting, such as around 4 degrees Celsius;In winter, when the room temperature is lower, the temperature of the refrigerator can be set on a higher setting, such as 6-8 degrees Celsius.
Don't open and close the refrigerator door too often
Frequent opening and closing of the refrigerator door can cause temperature fluctuations in the refrigerator room, affecting the freshness of food. Therefore, when using the refrigerator, the number of times the refrigerator door is opened and closed should be minimized, and the opening time should be minimized.
Separate food storage
In order to improve the freshness of the refrigerator, it is recommended to store the food separately. For example, keep perishable foods such as meat, fish, etc., on the bottom floor of the refrigerator because the cold air is heavier and will sink to the bottom;Whereas, non-perishable foods such as vegetables and fruits are placed on the upper level of the refrigerator.
Check the refrigerator temperature regularly
To ensure that the temperature settings in the refrigerator compartment are appropriate, it is recommended to check the refrigerator temperature regularly. You can use a thermometer to check it, and if you don't have a thermometer, you can test the freshness of the refrigerator. For example, place a glass of water in the refrigerator and watch it freeze. If the water freezes for a short period of time, the temperature of the refrigerator is too lowIf the water does not freeze for a long time, the temperature of the refrigerator compartment is too high.
4. Summary and Suggestions
The temperature setting in the refrigerator compartment is crucial for how well food is preserved. In general, it is appropriate to set the temperature of the refrigerator between 4-8 degrees Celsius. At the same time, it is also necessary to pay attention to things such as adjusting the temperature according to the season, reducing the number of times you open and close the refrigerator door, sorting and storing food, and checking the temperature of the refrigerator regularly.
In order to better extend the shelf life of food, it is recommended to buy a refrigerator with a thermostatic function, which can control the temperature of the refrigerator compartment more precisely and avoid the impact of temperature fluctuations on food. In addition, you can also consider using tools such as fresh-keeping bags and fresh-keeping boxes to assist in preservation, so as to further improve the preservation effect of food.
