When eating crayfish, I am obviously wearing gloves, why are I still full of hand oil?

There are three kinds of food in summer, beer, barbecue, crayfish, although it is autumn now, but it's okay, I still want to go to the food stall to eat spicy fried crayfish. When eating crayfish, you should pay attention to two precautions, the first is that it must be stir-fried, and the second is that it must be eaten by hand. It is a bit unhygienic to get started directly, so when we eat crayfish, the boss will give two gloves, but when we eat crayfish, we are obviously wearing gloves, why are we still full of hand oil?

One. Eating crayfish must be started.

Why do you have to get started with crayfish? Because if you eat crayfish with chopsticks, the first step will be to eat the shrimp meat so completely, second, it takes more time, and it is troublesome to use chopsticks to clip it, and third, you can't feel the fun of eating and drinking, so we must eat it with our hands when we eat crayfish, so that it is fragrant! <>

Two. The gloves that come with eating crayfish are too thin.

Then let's talk about why you wear gloves when you eat crayfish, but at the end you find that you still have oil on your hands. I think there are two reasons, the first is because the gloves that I usually eat crayfish with are the worst quality, the most general plastic gloves, it's okay to eat one or two, and if we eat too much, the oil will seep into the gloves, so when we take off the gloves, we find that there is still oil on our hands. <>

Three. Stir-frying crayfish will puncture the gloves.

After eating the crayfish, the second reason why he found that there was oil on his hands was that the crayfish was a crustaceous animal, and the claws, whiskers, and heads on his body were easy to puncture the gloves. Then stir-fry the crayfish, and the shrimp oil and seasoning sauce in it will penetrate into the gloves along this small hole, which is why we wear gloves and there is oil in them. But I don't think it's a big deal, if it weren't for the sake of elegance, you could have not even brought gloves and washed your hands after eating!

Because all the disposable polyethylene gloves on the market are thin and have low oil resistance, even when the gloves are worn, the hands are full of oil.

Because this kind of glove will leak oil, and the shell of the crayfish is relatively hard, and there are many thorns, so in the process of peeling the crayfish, the glove will be cut and the oil will stick to the hands.

Because the gloves we usually wear when eating crayfish are too thin, and they are also the kind of plastic gloves that are of particularly poor quality, so the hands must be oily.

This is because the crayfish has a lot of oil secretion, the gloves are disposable gloves, and the sealing is not particularly good, and the crayfish's pliers are likely to break the gloves.

Because these disposable gloves still have gaps, grease will enter the gloves, and disposable gloves are only used to keep bacteria out.

I think the main reason is that the disposable gloves are relatively thin, which may have been punctured in the process of eating crayfish, or because the main components of disposable gloves are composed of some compounds, which are very dense, which also causes the oil to pass through the disposable gloves.

Because the polyethylene raw materials used in the production of disposable film gloves are mainly low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), LDPE and LLDPE have low density, and there are more polymer molecules with branched chains, resulting in large molecular voids between polymer chains, and all oil will penetrate in.

The main component of disposable gloves may be composed of polymer compounds such as polyvinyl chloride, because its density is small, so the oil in the crayfish can penetrate the disposable gloves.

It's because the gloves are so thin that if you have nails, it's easy to pick them off, so you'll get oily.

Because the fat of the crayfish will enter the inside of the glove through decomposition, there will still be oil on the hands when wearing the glove.

Because there is no way to stop the oil on the crayfish from decomposing, some small molecules will enter it through the glove.

Because the density of oil is less than that of gloves, gloves cannot stop oil molecules at all.

Crayfish is a favorite delicacy and a delicacy that many people must order late at night, but the process of eating crayfish is also more troublesome, and most people wear disposable gloves to peel the shell. But there is a problem I don't know if you have noticed, when we eat crayfish, we obviously wear disposable gloves, but after eating, our hands are still full of oil. It is very likely that the gloves on the hands are too thin and have been punctured by the lobster shells, or it is possible that the oil molecules have stuck to the fingers through the gaps in the gloves.

There are three types of disposable gloves on the market, and most of the disposable gloves we wear when eating crayfish are polyethylene gloves. There may be two reasons why eating crayfish with disposable gloves still makes your hands full of oil, the first may be that the gloves are relatively thin, and the gloves are punctured by the crayfish in the process of eating, which is relatively easy to understand. There is also a possibility that there are gloves that only pass through gaps that we can't see, because the gloves we use when eating crayfish are usually polyethylene gloves.

When our gloves come into contact with grease, the gloves may swell to a certain extent, and at this time, the grease molecules will directly pass through the disposable gloves, thus making everyone full of games. <>

Since disposable gloves still can't get rid of grease, is it still necessary to use them? The answer, of course, is yes. In fact, the main purpose of using gloves in life is not to prevent grease, but mainly to deal with bacteria and achieve a barrier effect.

In our daily life, we will inevitably stick some bacteria on our fingers, and disposable gloves made of polyethylene have the function of blocking bacteria. Wearing gloves and eating crayfish can be very effective in preventing bacteria from entering the body, so as to achieve a healthy diet. <>

In daily life, we should also pay attention to the fact that when buying disposable gloves, try to buy products produced by regular manufacturers. Inferior gloves may be made from waste materials, which do not do a good job of blocking bacteria, and may also contain harmful substances. In short, when buying disposable gloves, we should face up to the problem and choose compliant and healthy products.

I think it might be due to the fact that your gloves are not very good quality, there is too much oil and it will seep through some of the gaps in the gloves.

Usually when we buy crayfish, we will be given a pair of gloves, but even if we eat crayfish with gloves on, we will still end up with a lot of oil. I think the glove is too thin, and the oil will still penetrate through the glove.

This is due to the fact that even after wearing gloves, oil is still drawn from the inside of the arm.

1. When you have spicy hands after eating crayfish, you can wash your hands with cold water, which can relieve the spicy pain, and if the spicy pain is more obvious, you may also put your hands into the ice water to soak for a while.

2. Chili pepper contains a lot of capsaicin components, so when eating crayfish, if the capsaicin in the chili pepper is stained on the hand, it will cause spicy hands, at this time, you can smear some vinegar on your hands, which can neutralize the acid and alkali, so as to relieve the spicy feeling.

3. The capsaicin and capsaicin in chili peppers are fat-soluble ingredients, so applying cooking oil to your hands can also relieve the spicy pain, and finally wash your hands with water and hand sanitizer.

4. Many toothpastes contain cool substances, so if you eat crayfish and spicy hands, you can also apply some toothpaste on your hands, let it stand for about 5 minutes, and then wash it with water, so that the spicy pain will disappear.

5. Capsaicin can be dissolved in alcohol, so the pepper can be smeared with an appropriate amount of alcohol on your hands, and the alcohol is more volatile, and it will also bring a cooling sensation during the volatilization process, which can relieve the spicy pain.

6. The shell of crayfish is very hard, and if you are not careful, you may puncture the thin disposable gloves, which will allow the oil to enter the hands, and there will also be spicy hands.

The disposable gloves we usually use are polymer compounds such as polyvinyl chloride, but the intermolecular gap between oil molecules is smaller than that of polyvinyl chloride, so there will also be cases where eating crayfish with gloves is still oily. In addition, the oil we eat is organic, and polyvinyl chloride is also organic, and the two are miscible, which will also cause the oil to penetrate through the gloves.

7. If the crayfish is ready, if the taste is spicy, you can add an appropriate amount of water to the pot, the water can dilute the spicy taste, so as to neutralize the taste.

Or you can add an appropriate amount of sugar to the crayfish, which can not only relieve the spicy taste, but also play a role in improving freshness.

In fact, even if it is a complete glove, it will still leak oil, because the disposable gloves we usually use cannot avoid oil leakage. Why? Let's start with the composition of raw materials for disposable gloves.

The disposable gloves we usually use are often made of PE material, and friends who have studied chemistry will have a certain understanding of polyethylene, which is a polymer compound, which is actually a long chain structure formed by the convergence of many small ethylene molecules "hand in hand", and a number of polyethylene polymers are intertwined together, forming a surface-like structure like weaving.

As we all know, disposable gloves are a very thin surface structure, when we use gloves, under the influence of external forces, the polyethylene molecular structure in the gloves will be gradually reversed, stretched, in the process, the polyethylene molecules will cause gaps, then the rest of the molecules are likely to pass through these gaps, and the oil is like this over the gloves. Friends who are interested will also find that water is actually not able to seep out of this disposable glove, so why can't water with a small molecular weight pass through, but oil can?

This is related to the structure of oil, we all know that polyethylene is an organic matter, and oil is also an organic matter, they are all non-polar molecules, there is a definition of "similar solubility" in chemistry, which means that very similar substances have a strong ability to dissolve each other, and water is a polar molecule, oil and water generally do not dissolve each other, which is equivalent to the exclusion of each other.

Therefore, when the water is in contact with polyethylene, the attraction between the two is weak, so the water will not penetrate into the plastic, and the oil molecules and polyethylene molecules attract each other, and the oil can penetrate into the plastic gloves. Of course, this session also takes a certain amount of time, usually 10 to 20 minutes. So even with disposable gloves, there will be oil on your hands.

Because the shell and pincers of crayfish are very sharp, they can cut through plastic gloves if you are not careful, and gloves are disposable and have no protective effect. So wearing gloves to eat crayfish is still a hand oil.

Because the molecular voids of the gloves are too large, the oil can enter our hands through these gaps.

The claws of the lobster have a hard shell, and if you are not careful, you will puncture the gloves, and the oil will also get on your hands unconsciously.
