Nowadays, many college students will bring back a lot of food when they go back to school on holiday, and sometimes they will go out shopping to buy a lot of food by themselves, but there is often no refrigerator in university dormitories. At this time, how to preserve food has become an urgent problem. Of course, we still encourage students to buy on demand, and don't hoard a lot of food that is not easy to preserve.
If there are some foods that need to be preserved, we can put them in a cool and ventilated place. If there is some food that needs to be preserved, we can use the washbasin to hold half a basin of tap water, then put the food in a bowl, cover it with gauze (mainly to prevent fly pollution) and put it in the basin. Finally, put the washbasin in a cool and ventilated place, so that the food will not go bad the next day, but it will not last long, so it should be eaten in time.
Precautions for proper use of refrigerator:
1, bottled drinks should not be put into the freezer, and bottled liquid drinks should not be put into the freezer to avoid freezing and cracking the packaging bottles.
Food can be put in a separate container after it is sealed. Fresh meat and fish should be sealed in fresh-keeping bags after treatment, and then put in the refrigerator. Vegetables and fruits should be dried and put in the refrigerator.
3. Store raw and cooked separately, and try not to mix them together, so as to ensure the cleanliness and hygiene of food.
Let the food cool before putting it in the refrigerator. When the food is still hot, we can't put it directly in the running refrigerator. This is easy to make the external temperature of food low and the internal temperature high, and the food is easy to deteriorate, which reduces the fresh-keeping effect of food.
5, there should be a gap between food, food storage should not be too full or too tight, there should be a gap in the middle.
