】 _Storage time_How long
Many people like to eat potatoes. Potatoes are rich in starch. They taste good. The preservation of potatoes is very important. If the potatoes turn green, do n’t eat them.In fact, this approach also prevents many people from participating. So, can potatoes be stored in the refrigerator?
How long can potatoes be kept in the refrigerator?
Let ‘s take a look next.
How long can potatoes be stored in the refrigerator?
In the low temperature environment of the refrigerator, the starch in the potatoes is gradually converted into sugar. If such potatoes are used for cooking or cooking, a series of terrible chemical reactions will occur.
The specific process is this. Under high temperature conditions, the sugar in potatoes will react with asparagine to form acrylamide.
According to research, polyamidoamide is a carcinogen that can synthesize the growth and division of nanotubes in the body, which is extremely harmful to health.
Because the refrigerator is relatively upstream, there is a lot of water, and potatoes are easy to germinate in this environment continuously.
Everyone knows that potato sprouts must not be eaten, otherwise they will be poisoned.
Reasons why potato sprouts cannot be eaten 1.
The germinated potato contains a toxic substance called solanumin, which has a very strong stimulating effect on the fever mucous membranes, has a paralytic effect on the respiratory central system, and also has a hemolytic effect on blood cells.
The specific manifestations of human poisoning are nausea, vomiting, diarrhea, severe blood pressure drops, smoking, dyspnea, and even heart failure and death.
If the potato is intact, the content of solanine is very small. Once germination occurs, the solanine content will increase by 5 or 6 times. It is mainly concentrated in the buds and around the buds. Fortunately, solanine does not spread.
Therefore, try not to eat germinated potatoes, if you eat, you must dig out the buds.
After the potatoes are stored in the refrigerator, the taste and taste of the potatoes will also be greatly reduced. From this perspective, potatoes are not suitable for the refrigerator, and they are not delicious.
Therefore, the best way to store potatoes is to keep them in a ventilated, dry, cool place, but not in direct sunlight.
When potatoes are exposed to sunlight, chlorophyll will increase, making the skin green, and at the same time, solanin will also increase.
Note that everyone must know that not only does potato have vegeterin when they germinate, but they also produce a lot of solanin when the potatoes turn green, soft, and black, so be careful.
Solanine is an alkaline substance that easily decomposes under high temperature and acidic conditions.
Therefore, when you fry potatoes, you must fry them. In addition, add a little vinegar and neutralize the acid and alkali to reduce the content of solanine more effectively.
