Food will speed up its corruption under high temperature, so food needs to be kept fresh in the refrigerator. However, the temperature of different positions of the refrigerator is also different, and it is more suitable to keep different food. So the following four seas net small editor teaches you how to put food in the refrigerator more reasonably.
In general, when refrigerators are placed in this way in various fields, the temperature of the refrigerator room is about 3-10 ℃, the temperature of the upper layer is higher than that of the lower layer, and the temperature at the door is the highest, while the temperature near the back wall of the refrigerator is the lowest, which can be placed in a suitable place according to the characteristics of the ingredients themselves.
Refrigerator door frame
Open the door of the refrigerator, you can see that there are many grooves at the door frame to place the canned goods. However, because the door of the refrigerator is often open and close to the opening, the temperature here is on the high side, so it is more suitable to place the things that are not easy to be damaged, such as seasoning, general canned drinks and other foods that can be temporarily placed at room temperature.
The refrigerator door frame provides a large vertical space and is more convenient to use. Most people will put the canned milk here, but the temperature here is high, so it is not suitable for storing milk or dairy products that are easy to rot.
The refrigerator door frame is suitable for placing seasonings, canned drinks and other ingredients that can be temporarily placed at room temperature. Food classification into fresh-keeping boxes helps to avoid mutual pollution and extend the shelf life.
Refrigerator top:
The temperature near the top of the refrigerator is the lowest, which is suitable for storing perishable food, such as yogurt, bean products and milk, as well as cooked food such as leftovers commonly found in families, which helps to prevent food from spoiling due to bacteria breeding. There must be some space between the food and the back wall of the refrigerator, which is easy to freeze in direct contact.
Refrigerator lower level:
The lower part of the refrigerator near the door has a high temperature, which can store all kinds of vegetables, fruits, etc. which are easy to frostbite. They can be put into a fresh-keeping bag first and then into the refrigerator to avoid frostbite due to low temperature. Food that has not been cooked and needs to be preserved at low temperature is suitable for the second half of the lower layer, such as fresh meat and seafood purchased from the traditional market, which is convenient for immediate use when cooking. In order to prevent cross contamination of different ingredients, it is suggested to separate several blocks to store meat, fruits, vegetables and seafood.
Freezer:
The temperature of the freezer is generally around - 18 ℃. It is used to store foods that need to be kept fresh and watery at low temperature, such as bread, steamed bun and other starch, as well as seafood and meat. Putting bread into the freezer can not only prolong the storage period, but also avoid water loss. In addition, other frozen foods that need to be kept for a long time can also Put it in the freezer. The ingredients to be put into the freezer can be put into fresh-keeping bags or plastic containers first, which can save more space. It is not recommended to use glass containers for filling, so as to avoid cracking due to low temperature.
Precautions for use of refrigerator point 1 do not open and close the refrigerator door frequently:
First, figure out which ingredients to take. When you open the refrigerator door, take them quickly. Avoid frequent opening and closing of the refrigerator. It is easy to increase the internal temperature of the refrigerator. It will not only bring in germs, but also increase the electricity cost.
Point 2 fridge eight full:
Do not overfill the food, leave a certain gap to facilitate the convection of cold air and maintain low temperature. If too many items are put in, in order to adjust the internal temperature, the condenser of the refrigerator will exhaust the hot gas, which will cause the surrounding temperature to rise, make the food materials rotten, and the electricity cost will also rise! The way to save electricity, money and keep the food materials safely is: reserve a certain space for the refrigerator interior!
Point 3 classification saving:
Put the ingredients into the fresh-keeping box to help maintain proper humidity and prevent different ingredients from being polluted due to contact with each other! The raw food and cooked food must be stored separately, and then put into the refrigerator after being packed in the fresh-keeping bag or box. It is recommended that the cooked food be placed on the top of the refrigerator and the fresh food be placed on the bottom. It should be noted that even fresh fruits and vegetables cannot be placed together, because many fruits will produce ethylene to help ripen, but this material will affect the quality of other fruits and vegetables, making them aging, yellowing and even sprouting. Therefore, fruits such as apples, peaches, plums, pears, melons and so on must be kept separately from other fruits and vegetables.
You can put a label on the fresh-keeping box or bag, and write down the type of ingredients and the duration of consumption.
