and other nutrients, especially arginine produced after the hydrolysis of proteins in pig trotters.

speed.

Mainly because the hair is shaved, and then some pigment is added, so it will appear so white, which makes the quality of the pig's trotters very bad.

The pig's trotters sold on the table are usually very clean, and the color of the pig's trotters is not particularly fresh when the wind blows, so it will look particularly white.

Because these trotters are most likely chemical trotters, they may have been soaked in medicated solutions.

The whitishing may be a "chemical pig's trotter", which is mainly soaked with three chemicals: sodium hydroxide (commonly known as caustic soda), hydrogen peroxide (commonly known as hydrogen peroxide), and sodium nitrite. After the caustic soda is added to the water, the solution is strongly alkaline, and the pig's trotters will become bloated and obese after soaking in such a solution overnight, and then bleached and kept fresh with hydrogen peroxide, and then added sodium nitrite for coloring, and the pig's trotters will become "good-looking" white and fat. The best-looking white fat pig's trotters were soaked in potions.

Hydrogen peroxide blisters pig's trotters are mainly whitening, and after the pig's trotters are soaked, they are very beautiful. Hydrogen peroxide has the function of drifting, and the oxidation is particularly strong, which can remove all the dirt on the surface, and can also remove odors. However, it is very dangerous to soak pig's trotters with this potion, and if you eat too much, it will cause poisoning.

A method for identifying whether pig trotters are soaked in medicated water.

1. The pig's trotters soaked in the potion generally swell, and they will be much larger than the pig's trotters that have not been soaked normally, so it is not necessarily good to choose the big one. Usually, most of the pig's trotters on the market are about eight taels to one catty and two taels, and if they rise too much, it is estimated that they have been soaked. When buying pig's trotters, you must not patronize the large and good-looking ones, and the generally inconspicuous pig's trotters are ***.

Of course, if it's too small, it's not a matter of food safety, it's a matter of satisfying your appetite.

2. Touch it with your hands, and feel sticky or not. Pig's trotters that have been soaked in potion will feel sticky, and those that have not been soaked will not be sticky. Also, press lightly on the pig's trotters with your hands, the soaked pig's trotters feel harder, and the unsoaked pig's trotters should be softer.

3. Get closer and smell the smell when you buy. The soaked trotters have a faint smell of potion, and sometimes the smell of the potion can also mask the fishy smell of the pork itself. If it has not been soaked, it will have no medicinal smell, and there will be a fishy smell of pig's trotters.

4. The ability of double oxide to remove oil stains is strong, and there will be no oil stains on the pig's trotters after soaking in this potion, so it can be identified in the water, and it is estimated that the oil foam can not be found.

1. You can fry the pig's trotters with oil for a little (if you use a little lard, it is better), so that the egg whites can be melted into the soup later; 2. Cook pig's trotters under cold water; 3. Put enough water at one time, and do not add water in the middle of cooking soup; 4. Cover the pot and bring to a boil over low heat; 5. Use a clay pot instead of a stainless steel pot; 6. Use an open flame, do not use an electric stove or induction cooker or electric sand pot.

Unless treated with chemicals, it will not turn whitish by normal means.

If you soak in water for a long time, you have either soaked it in chemicals.

Is it better to buy pig's trotters as white as possible or bigger as possible? How do you choose a pig's trotter? It's not that whiter and bigger is better.

Pick the trotters. 1. Pig skin is dry, non-sticky and elastic.

Whether it is pork knuckles or pork, if it is fresh, the surface of the pork skin will feel dry and will not be sticky. If the pig's skin becomes sticky, it means that a large number of bacteria have multiplied, so the pig's feet are rotten and cannot be bought.

Fresh pork knuckles are rich in water content and have good elasticity. When you press the meat with your hands, you can feel the ** of the meat. If it is loose and there is no reaction, it is a rotting pig's trotter.

2. The bigger the white, the worse the quality.

Normal trotters are pink or light yellow in color and not very large. If it's particularly white, it's extraordinarily large, it's a chemical pig's trotter bleached with hydrogen peroxide. Don't buy it. The average pig's trotter is one inch long and no more than 8 centimeters in diameter. If this criterion is exceeded, it is soaked.

3. The fishy smell is small and there is no peculiar smell.

It is normal for pig's trotters to have a slight fishy smell. After all, if you step on the ground every day, there will definitely be a fishy smell. If a trotter has a strong fishy or sour smell, it has gone bad.

If the potion has a pungent smell, it is a chemically treated pig's knuckle. There will be a lot of chemical residues. Don't believe it.

4. Pig's feet have large pores and are not easy to use.

Fresh and high-quality pork knuckles can be seen from the pores of the epidermis. They are thin and numerous. They are healthy pigs.

If the pores are thick, one may be an old sow's pig's foot, and the other may be a dead pig's foot. They are all bad pig's feet. Don't buy them.

The quality is definitely not good.

5. Look at the feel.

Whether you go to the supermarket or the market to buy pig's feet, you should touch them with your hands first. The skin and meat of fresh and natural pork knuckles are closely connected, while poor quality pork knuckles will have a noticeable feeling of separation of skin and meat. Also, the trotters feel sticky.

There is a layer of mucus on the surface, or it feels very hard. Most likely a pig's trotter soaked in a chemical solution.

6. Look at the color.

Many people don't know how to choose a pig's trotter. They only look at the color of the surface. They think the whiter the color, the cleaner it is, and the better it tastes.

In fact, this is not the case. Don't be deceived by the "** value" trotters. These white-looking pig's feet may have been soaked in a chemical solution, giving them a particularly white color.

If it is a normal trotter, the color should be light yellow or light pink.

7. Look at the opening and closing.

The trotters passed the test in the first two steps. Finally, we must see the beginning and the end of it. If the two valves of a pig's trotter are tightly closed, it is a good quality pig's trotter. If there is swelling and opening, you should pay attention. It may have been soaked in a chemical solution.

It should be as big as possible. Actually, I don't think the whiter the better, mainly because after it is too white, I will feel if there are some preservatives added to it. You have to look at the hardness of the trotters.

I think you should choose a pig's trotter with a relatively large number. According to the quality of the trotters, you can choose according to the premise or hind legs, you can also choose according to the hair of the trotters, and you can choose according to the freshness of the trotters.

I think the whiter the color, the better, because the whiter the color, the better the health of the pig, and the pig's trotters should also be white and thick.

I think that when buying pig's trotters, you can choose according to the situation at that time, and it is not that the whiter the color, the bigger the better, and we can observe the overall pork situation.
