When buying fish in the wet market, some fishmongers use black plastic bags, what is the reason?

Mainly because the black plastic bag is cost-effective, the plastic bag is relatively strong, and you can put some water in it to avoid the situation of fish dying.

Because black plastic bags do not refract sunlight. That is, protected from light. Fish will not be exposed to sunlight and die.

Black plastic bags are much cheaper than other color plastic bags, which can reduce costs, and general black plastic bags are more practical.

Summary. Hello, before selling fish there were no plastic bags with cages, or straw ropes. In the early 80s of the last century, plastic bags were rarely seen in China's cities and villages, when people bought vegetables in plastic baskets, bought tofu or cold noodles in bowls and basins, bought a large piece of meat wrapped in paper, bought a fish with straw ropes, popped corn with bamboo baskets, vinegared soy sauce and took their own bottles, bought apples with their own net bags, bought bulk candy with paper wrapped, people living in the south bought noodles and went home to eat early, and had to use bowls to bring back.

In the early 80s of the last century, plastic bags were rarely seen in China's cities and villages, when people bought vegetables in plastic baskets, bought tofu or cold noodles in bowls and basins, bought a piece of meat wrapped in paper, bought a fish with straw rope, popped corn and carried bamboo baskets, beat vinegar and soy sauce and took their own bottles, bought apples with their own net bags, bought bulk candy with paper wrapped, people living in the south bought noodles and went home to eat early, and had to use bowls to bring back.

Thank you. Now we are all using plastic bags, how can we stop it.

Everyman. You can use a cloth bag to go out, and ordinary people can't force it, so they can only start from themselves and the people around them.

We all know that most businessmen are mercenary, and what they value most is the final profit, so as long as they can make a little more, they will not let go of that opportunity. When fishmongers put fish or shrimp in our bags, they will quickly put more water in them, often when we are not looking, and the black bags block our vision so that we can't see it. When the fish in the bag is weighed, the fishmongers will often put some more water in it, saying that it will make the fish survive longer, so that we will not be able to find out their careful thoughts, so that a fish can be sold for one or two more dollars than the original.

I'm afraid that the fish and shrimp will run back when they see the way they came.

Because the black plastic bag can hide the color of the fish well and the freshness is not visible, it is easier to sell.

First of all, these black plastic bags are relatively strong and not easy to rot, and then because they are black, others don't know about filling some water in the process.

One is because of the beauty, after all, some people will feel very fishy when they see fish and shrimp, and they will feel uncomfortable, and the black plastic bag can block the view, and the second is that the quality of the black plastic bag is better.

Because the black plastic bag is not easy to see the extra water inside. This is the routine of the vendors.

Because black bags are cheaper than other colored plastic bags, and the fish in black bags look cleaner.

One is that the ** of the black bag is cheaper, and it is not a ready-to-eat product, so the black bag can be used, and the other reason is that the fish are more bloody after being slaughtered.

There is a kind of black bag that is relatively strong, the fish is generally not too small, and it will not break with that kind of strong bag, and it is generally necessary for fishmongers to dispose of the fish, and it is not good to have blood and water in a transparent bag, and the black bag is economical.

Why do fishmongers always use black bags for fish? In fact, there are several reasons for this, one of which is that the cost of black thick plastic bags is slightly lower, and the most important reason is that the seafood put in this way is not easy to die, because it is opaque, the fish will think that it is a dark day, and the metabolism of the fish will be smaller, in a state of low consumption, in terms of activity, the oxygen consumed will be less, and the fish will survive for a long time.

In fact, every industry in life has its own habits, these habits are for a reason, are summed up from the experience of life, we know that it is not easy to transport seafood in the past, once these seafood see the existence of nearby creatures, they will panic, flee in all directions, resulting in excessive physical exertion, and oxygen will also be consumed in large quantities, so when transporting goods, they are all used in black space, in fact, in the past when transporting the army, there are also planes, Usually turn off the light shield, in fact, it is to let everyone enter a loss of interest and tension in the outside world, reduce people's excitement, and then reduce the consumption of oxygen in the air, in fact, such examples are very common in life.

If you use a transparent bag to contain live fish, then it will see the surrounding people or things, feel that there is danger approaching, and want to avoid and escape, it will be nervous and waste energy, and the probability of fish death is much higher, and fishermen must have discovered this secret in the long-term transportation process, and now they are starting to use, people who don't know the inside must think that the reason for the low cost of black plastic bags is not the main reason.

Of course, this is for those more active fish, if it is the kind of sardines that are more scattered, they don't need it, and they also have to put catfish, because catfish are very sensitive to changes in the environment, they will jump up and down, and the sardines don't have time to die, don't transport them to the place, these are actually summed up in the practice of life, we call it the "catfish effect".

If the road is long, fishermen will also fill the bag with some oxygen, so that the fish can survive longer, and now there are logistics companies that can transport seafood over long distances, of course, all by air, and live, all need oxygen, and even small pets can be transported by express. Human intelligence is getting higher and higher, and it used to be difficult to transport plants, but now it can be so high, I don't know if it will be consigned to humans in the future.

There are many things worth observing and learning in life, we must learn to experience with our hearts, think with our brains, summarize more useful and beneficial experiences, do not simply think about one thing, comprehensive thinking will help us judge and understand things.

Although the cost of black plastic bags is low, compared with the profit of seafood, it is certainly not the main reason, the main reason is to improve the survival rate of seafood, so that they will not die during transportation, or consume too much, especially crabs and other refrigerated transportation, even more reason.

When you go to the market to buy fish, why do fishmongers use black bags? Hidden in it is a big cat.

If you use black bags to fill fish, there is no guarantee that some merchants are cheating customers. So when people go to buy fish, especially when they see this kind of black bag containing fish, after taking it, they must check whether there is water in these black bags. In fact, whether it is black or white tape, it is more difficult to rot, and they will cause great pollution to the environment around us, so in the process of shopping for food, try to use your own bags to reduce this plastic bag pollution.

When we go to the vegetable market to buy vegetables, we often find that the merchants who usually sell vegetables will use transparent bags to store vegetables, but when we buy fish, they all use black bags to store fishThis seems to have become an unwritten rule for fish sellers, and whether the choice of black plastic bags must have a certain connection with selling fish?

First of all, the black plastic bag ** is relatively cheap, which is naturally a better choice for fish sellers, and the black bag is relatively strongFresh fish usually still maintain a certain vitality, and even when you take it home, you will be alive and kicking, usually when you buy fish, you will add a small amount of water to the plastic bag to keep the fish fresh. This requires the plastic bag to be stronger, otherwise if it leaks in the middle of the road, it will be troublesome.

Secondly, when we buy fish, many people will ask the boss to help deal with the fish, so there may be some blood stains left on the fish. In this way, if you use a transparent plastic bag, everyone can see that you are holding a blood-stained fish, which seems unsightly, and the black plastic bag can prevent the blood from showing up and is more privacy-protecting.

Although the third situation is relatively rare, there will still be individual cases, that is, some unscrupulous traders will use some methods to reduce the weight of two catties. For example, if you use one fish when you weigh it, you can replace it with another fish when you bag it, and if it is a transparent plastic bag, this operation is easier to detect. In addition, some unscrupulous traders will also take this opportunity to add more water to it before the time of weighing, resulting in heavier fish, and black plastic bags are easier to disguise this behavior.

I think the fish in the vegetable market are not good-looking, and most of the fish bought in the vegetable market are processed fish, and the perception is a little poor, and people who are afraid of fish like me will be shocked.

Personally, I think that on the one hand, this is a business opportunity, for fresh vegetables, as soon as others ask, then they may go to this place to buy, on the other hand, if the fish is killed, it may be more embarrassing.

The material of the black plastic bag is relatively high-quality, and the average family will want live fish, buy one to go home, and kill the fish yourself. It takes a process for a live fish to get from a foam box to a black bag, during which time if the fish struggles, the normal plastic bag will definitely break, but the black plastic bag will not break.

That's because the black bag is relatively strong, and there will be water inside, add weight, and the black bag will not be visible if it is water.

As a housewife, a friend has to go back and forth to the vegetable market every day, whenever he buys seafood, he will always receive a big black plastic bag, especially when buying fish, almost every house is a black bag, not some transparent bags, now people, every day to go to work to cook, who cares about this small problem? It wasn't until my friend told me the truth that I learned where the "profiteers" came from.

Intentional watering. Remind everyone again, buy seafood must go to a fixed stall, we can't beat a stick to death, say a personal experience of one thing, buy fish with a black bag, which one is like this, when loading fish, the merchant will deliberately "drop the bag", here is not the fish, but the plastic bag, has been loaded with water in advance, it weighs with the fish, it will add extra weight, a fish paid 5 yuan more, fortunately, after going home to weigh, and came back to him, only to return the money to me, the fishmonger's method is too fast, The main reason is to lack two catties, and nine taels of fish can weigh one catty.

Steal beams and change columns. The most afraid of buying fish is the raw face, no matter what kind of fish you pick, eventually come home are dead fish, a little careful friends will find that this is "dropped", fresh fish was replaced with dead fish, from the ** point of view, it will be doubled, and the dead fish is not fresh, the meat will not be delicious, some young people are the key objects, mainly just play with the mobile phone, will not pay attention to the fishmonger's "small actions", this is the so-called stealing beams and changing pillars, live fish to home will die, some people still think that this is a lack of oxygen on the road, in fact, the cause of death is unknown.

Black is poisonous. Black plastic bags are in direct contact with food, will contaminate food, many people feel a bit of a fuss, first of all, this kind of bag is cheap, in order to reduce costs, the first choice is black bags, it is made of waste ** garbage, plus a large number of black dyes, so that the bag is blackened as a whole, this is to cover up the color of raw materials, and even some materials are loaded with fertilizers, pesticides, and garbage, if they penetrate into the food, it will seriously endanger human health.

Which plastic bag is safe?

1. Milky white or transparent, with a lubricating feeling to the touch, it is best to print the three big words "food grade".

2. Non-toxic plastic bags, after fire burning, there is no obvious smell, and the flame head will be cyan.

Try not to use plastic bags with colors, including black, yellow, red, etc., the feel is obviously sticky, this is because a large number of dyes are added, and the friends who have used black plastic bags must remember its smell, smelling very nasally, a strong chemical smell, which is mostly produced by small workshops, and harmful substances will not be low.

In order to reduce costs, businesses will continue to use black plastic bags, this kind of bag is really good quality, not easy to scratch, and relatively strong, but it is better to use less, if it really can't be avoided, here is a small suggestion for you, to stare at the hands of fishmongers throughout the whole process, to avoid being transferred, there is a shortage of catties and two phenomenon, the elderly are smarter, I am afraid that some young people, the whole process only cares about playing with mobile phones.

Merchants slaughter people three times.

1. The black bag is deliberately filled with water.

2. Dead fish steal beams and replace pillars.

3. Five shrimps become three shrimps.

First of all, the black bag is heavier, even if there is a little water in it, you can't see it, and you can add more on the catty. The second is that the freshly killed fish will have blood, mucus and other substances, and it is more disgusting to pack it in a transparent bag.
