Refrigerators are items and foods that are refrigerated, frozen or fresh. Everyone must be very clear. So why do fresh foods need to be kept in the refrigerator? Can't you put it outside? Because most of the time, we go to the supermarket and see many fresh products directly on the shelves. In fact, these products need to be processed on the same day. Therefore, except for special fruits and vegetables, there is no need to use the refrigerator to store them, or off-season Food is usually refrigerated in the refrigerator to better extend its life in a low-temperature environment and obtain fresh preservation and storage, so let us first understand what is fresh and what is included? Fresh food refers to the primary products that are sold without further processing, such as cooking and making, requiring only preservation and simple layout, and in-situ processing. In products such as bread and cooked food, it seems to contain a variety of fresh foods. Many fresh foods must be in the freezer
So what are the benefits of refrigeration? First of all, it is definitely there. Refrigeration refers to storing food in low-temperature equipment to prevent spoilage and rot. Generally, the temperature of cold storage is in the range of 4 to 10 degrees, and the temperature zone of normal temperature is in the range of 18 to 22 degrees. Then according to different food temperature requirements, adjustments are made to curb its metabolism and extend its life. The temperature in cold storage cannot be constant at a certain temperature value. The storage temperature fluctuates within a certain range due to factors such as the performance of the refrigerator, the size of the storage capacity, and the temperature difference between inside and outside. Generally speaking, the storage temperature of food is lower, and the smaller the range of change, the better. This is conducive to food preservation, to prevent loss and low temperature physiological diseases. In this way, we can better benefit the refrigerator to keep fresh and refrigerate, in order to achieve our purpose. All, fresh food must be refrigerated in a freezer, so that we can feel clean and hygienic.
