.
 Many friends began to isolate themselves at home again
.
If you don’t want to eat instant noodles every day during the quarantine period, it’s a good idea to “train food” appropriately in advance
.
But in summer, the temperature is high, how can we scientifically collect food and extend the shelf life of food? Our common foods can be roughly divided into three categories according to the shelf life: meat, fruits and vegetables, and grains
.
 MeatMeatBacon and sausages can be stored outside the refrigerator in a cool and dry place
.
If fish and meat are stored frozen, the shelf life can be extended a lot
.
When thawing, put it in the refrigerator one day in advance, so as to avoid the loss of nutrients and reduce the growth of microorganisms
.
However, you should be careful not to defrost repeatedly, which not only increases the risk of microbial contamination, but also deteriorates the taste and flavor
.
Divide the food into small portions before freezing, just take one portion at a time and thaw
.
 Fruits and vegetablesIn the refrigerator compartment, the most effective way to extend the storage time of fruits and vegetables is to reduce the evaporation of water in the fruits and vegetables
.
You can wrap green leafy vegetables and other easily wilted ingredients with a safety bag or plastic wrap in advance, so that it will be no problem to keep it in the refrigerator for one week
.
Beans, eggplants, green peppers and other ingredients can last for 2 weeks
.
Potatoes, onions, carrots, cauliflower, garlic sprouts and the like with less water will last longer and will definitely be able to delay the isolation period
.
But pay attention to the fruits and vegetables put in the refrigerator can not be washed, and there should be no water on the surface, otherwise it is easy to breed bacteria and cause rot
.
 foodSome people put food in the refrigerator, but they don't realize that food is different from fruits and vegetables.
There are many gaps on the surface, which makes it easy to absorb moisture
.
And there is a lot of water in the refrigerator.
It is necessary to know that mold can withstand the low temperature of the refrigerator, and there is still a risk of mold growth over time
.
The correct method is to store grain and beans in a dry environment, and put one or two peppers in it, which can also play a role in preventing insects
.
 Of course, the above are no alternatives, and the ingredients are of course the best to eat fresh
.
The refrigerator is not a safe, and it is best to renew the leafy vegetables stored in the refrigerator every three days
.
Rotten fruits and vegetables should also be thrown away as much as possible.
It is not recommended to cut them off and continue eating
.
May there be no more pandemics in the world
