What is the reason why the shredded pork with potatoes turns white the next day after being put in t

Stir-fried shredded potatoes and shredded pork will turn white the next day after being put in the refrigerator, probably because the moisture in the shredded meat and shredded potatoes solidifies at low temperatures, causing the color to turn white.

In terms of the list of ingredients, potatoes and shredded meat are relatively common ingredients, and shredded meat may absorb water during the marinating process, and there is also water in shredded potatoes. After being placed in the refrigerator, this moisture may solidify at low temperatures, forming a white substance.

In terms of production steps, it is usually necessary to marinate the shredded pork for a period of time when making fried shredded pork with potatoes, and the shredded meat will absorb some of the water during the marinating process. If you notice that the shredded meat turns white the next day after putting it in the refrigerator, it may be because the moisture solidifies into a white substance at low temperatures.

Therefore, when making fried shredded pork with potatoes, you need to pay attention to the moisture in the ingredients, especially when you find that the color of the ingredients turns white after low temperature storage, you can try to heat the ingredients in the microwave to evaporate the water, thereby improving the color of the ingredients. At the same time, you can also add an appropriate amount of salt and sugar to taste during the production process, but be careful not to add too much, so as not to affect the texture and taste of the ingredients.

Don't eat potatoes overnight, they will produce solanine, which is poisonous. If a large amount is consumed, the poisoning is extremely obvious.

A grandmother in my neighbor cooked a potato for a one-year-old baby, ate half of it, and felt that it was a pity to throw away the remaining half, so she put it in the refrigerator, and fed the baby the next day, but later went to the hospital, because of poisoning, her lips were blue, but fortunately she went in time.

FYI.

Summary. The shredded potatoes turn red because they come into contact with oxygen in the air after being cut, resulting in an oxidation reaction. However, if the shredded potatoes turn white again, it may be because the oxide on the surface of the white shredded potatoes has been washed away by moisture, or it has been restored when it is heated and cooked.

In addition, shredded potatoes lose water when they are cut, and if they are stored for a long time, they may become dry due to water loss, so they will look white.

The shredded potatoes turn red because they come into contact with the oxygen tung gas in the air after being cut, resulting in an oxidation reaction. However, if the shredded potatoes turn white again, it may be because the oxide on the surface of the shredded potatoes has been washed away by moisture, or it has been heated and cooked. In addition, shredded potatoes lose water when they are cut, and if they are stored for a long time, they may become dry and dry due to water loss, so they will look white.

Can you add, I don't quite understand it.

The reason why shredded potatoes turn red is because the amylase enzyme in potatoes oxidizes when it comes into contact with air, producing an enzyme called polyphenol oxidase, which causes potatoes to turn red. However, this change does not affect the nutritional value and taste of the potatoes. The reason why the shredded potatoes turn white may be because the polyphenol oxidase in the potatoes has been reversed for too long, or because the shredded potatoes have been washed away by excessive washing during processing.

In addition, if the shredded potatoes are not eaten after processing, they may turn white due to oxidation. Whether the shredded potatoes turn red or white, they will not have any effect on human health. It is recommended to minimize the number of washes when handling shredded potatoes to avoid the loss of polyphenol oxidase, and at the same time eat shredded potatoes in time to keep the taste fresh and the nutrients of the ears intact.

I think the shredded potatoes have changed color in the refrigerator for two days, so don't eat them, and the potatoes are not too expensive, in case you eat them badly, the gains outweigh the losses.

Potatoes are easy to oxidize and turn black after cutting, which is a normal phenomenon, because there is a large amount of starch on the surface, which will make the color of potatoes red and black in the air, but it will not cause harm to the human body, but this kind of potatoes are also easy to stick to the pan when fried, and the taste is not good.

So even though your potatoes are black overnight, you can still eat them, even if you eat nothing, but after all, the color is not very comfortable, and it is estimated that the nutrition has also been lost, so it is recommended that you give it up and don't eat it, especially in summer, you still need to pay attention to hygiene!

Nightshade is green, and this potato is generally about to sprout, and potatoes that are sprouted are not edible, because the solanine produced is poisonous.

It's not that the potatoes turn green after a long time, but they are not well preserved, you put the potatoes in the dark place in the corner, or in the basement, so that they don't turn green.

Can you eat potatoes when they are blue and peel off.

Potato skin green is a situation that we can often see in our daily life, if the potato skin is green, then it is often a sign of potato sprouting, due to potato skin sprouting or potato skin sprouting, then a large number of toxins will be produced, especially solanine and other substances are often easy to cause food poisoning.

In addition, it is best not to eat fresh potato skins, because potato skins contain a large amount of alkaloids.

Even if it is cooked, it is not allowed to thin the skin, because the alkaloids often penetrate deep into the potatoes through cooking, causing diarrhea and abdominal pain after eating.

and other symptoms, which are also prone to moderate disease.
