Can shredded potatoes still be eaten when they turn black? Shredded potatoes is a common practice. The first thing is to clean the potatoes and cut them into thin wires. However, many friends have noticed that it is easy for potatoes to turn black after shredding. Can the blackened shredded potatoes still be eaten? What is the reason why potato silk turns black? Let's have a look
1、 Can shredded potatoes be eaten when they turn black
Potatoes can be eaten safely after they turn black, because in general, potatoes turn black because they will oxidize after contacting with air, but potatoes will stick to the pot after they turn black, because some potatoes contain high starch content, and the situation of sticking to the pot itself is a little more serious than other ingredients, The blackened potatoes are even worse, and the eating taste of the blackened potatoes is not very good. Therefore, it is best to cook fresh potatoes when eating potatoes, so as not to have a certain impact on the eating taste. Some potatoes may be blackened because of deterioration, so this kind of potatoes blackened because of deterioration should not continue to eat, After eating, it will have a certain impact on health.
2、 Why is it dark
Most of the reasons for the blackening of potatoes are due to the oxidation of potatoes. Generally, the oxidized potatoes can still be eaten normally, but attention should be paid to the problem of sticking to the pot when cooking, because potatoes contain rich starch, which has a little problem of sticking to the pot itself. After blackening, the problem of sticking to the pot will be more serious, Therefore, attention should be paid to during cooking, and the edible taste of potatoes after oxidation and blackening is not very good. The reason why potatoes have this oxidation problem is that potatoes contain a certain amount of starch, which will accelerate oxidation after being cut again, resulting in redness and final oxidation on the surface of potatoes, In fact, many ingredients in life are the same as potatoes, just like apples that are exposed to the air for a long time after being cut. Therefore, this kind of food with discolored skin due to oxidation can be eaten safely, but generally the taste is not very good, so you should pay attention to it when eating, It is best to cook the ingredients fresh and eat them. Do not eat them after they are stored for a period of time, which will lead to the loss of nutritional value of the ingredients, and the eating taste will not be too good.
3、 How to keep the cut potato shreds black
As for how to preserve the cut potato silk, it can be stored in water or in the refrigerator. Such potato silk will not change color. If it is stored in water, the starch content can be reduced by a part, which can effectively isolate the oxidation in contact with the air. It is necessary to pay attention to the problem of changing the water when soaking at ordinary times, If the potatoes are stored in the refrigerator, it is best to wash the potatoes and cut them into filaments, put them in the fresh-keeping bag, isolate the air and put them directly in the refrigerator, which can also save the potatoes well and reduce the blackening.
The blackening of potatoes can continue to be eaten, because potatoes themselves are also a kind of food material with high starch content, so usually cut potatoes will be oxidized if they come into contact with air. At this time, it is necessary to keep potatoes well.
