How to identify hairtail fish containing formaldehyde, and how to identify hairtail fish soaked in f

Formaldehyde, as a widely used material in modern industry, has been added to food by many unscrupulous traders in order to preserve freshness and preserve preservation. The hazards of formaldehyde are well known, so how to identify formaldehyde-soaked hairtail?

Formaldehyde will denature the hairtail protein, and the shrinkage stress is different when encountering high temperatures, so when frying is disturbed, the phenomenon of bursting and rolling will occur.

When buying hairtail, bend the hairtail, and the hairtail soaked in formaldehyde will rebound faster and appear very tough. Normal hairtail fish is soft and has poor elasticity.

After long-distance transportation and stall placement, the appearance of the normal hairtail fish will be damaged to a certain extent, and it will not look good. The formaldehyde-soaked hairtail is shiny. It's been dead for so long, and it still looks so energetic, there must be something wrong!

Formaldehyde soaked hairtail is tightly fleshed, the meat is very porcelain and elastic, and the hairtail of normal grinding Chundan, a finger press a pit, there will be fingerprints left.

Large regular markets and supermarkets will have perfect cold chain transportation, and the detection of all aspects is relatively perfect, and generally speaking, formaldehyde will not be used to smash their own signboards. Consumers should try to buy from these places as much as possible.

Summary. Formaldehyde is certainly for a pro that hurts.

The release of formaldehyde in the newly renovated house is particularly violent, and it is summer, formaldehyde is easy to volatilize slowly at high temperatures, and formaldehyde is very soluble in water, formaldehyde volatilized in the air will be dissolved in water in large quantities, and the fish living in the fish tank are particularly sensitive to formaldehyde dissolved in the water mold, once it exceeds a certain level, it will cause coma and rot symptoms, and if it is too serious, it will also lead to the death of goldfish.

If the goldfish is not dead, it does not prove that the indoor formaldehyde is not too high, and it is not harmful to the body.

Not really.

Formaldehyde should still be diluted more in the activated carbon package and green plants.

My family sells carpets, and the black rubber mats are not all formaldehyde.

There will definitely be formaldehyde when it is just produced.

Harm to the human body.

It will volatilize on its own over time.

Is it harmful to the human body?

Formaldehyde is certainly for a pro that hurts.

The 6 types of fish with the most formaldehyde: oversized fish, fried hairtail, deformed fish, wild fish and reputation, salted fish, and yellow eel.

1. Oversized fish.

The heavy metal content of large fish or long fish may be relatively high, and after too much heavy metal is ingested into the human body, it will soon affect the operation of body functions, and even excessive heavy metals may occur, which is not good for health.

2. Fried hairtail.

Hairtail fish is also a kind of fish that we often eat in our daily life, containing relatively rich nutrition and low calories, the reason for the flowering of hairtail fish ** is that they may carry a large amount of formaldehyde, and businesses will use formaldehyde to keep it fresh, but this hairtail fish is not conducive to the health of Xiaochen.

3. Deformed fish.

These so-called deformed fish may have a lot to do with the living environment. For example, if the fish lives in polluted waters, it will cause some chemicals to cause genetic mutations, so it will grow into deformities, so this kind of fish is not safe.

4. Wild fish.

Fishing is indeed a great form of recreation, but it is not recommended that you eat fish, because the natural environment has changed a lot now compared to a few decades ago, and the water in which fish live may not be so clean, so eating wild fish regularly may also affect your health.

5. Salted fish.

Many people in coastal areas add a lot of salt to the fish they catch or special cooking methods for salting, and the salt in salted fish is relatively high. After a large amount of intake into the human body, it is easy to cause a certain burden and impact on the body, and it may also contain a large amount of nitrite.

6. Yellow eel.

Eel is also a kind of fish with few spines, but eel is more special and likes to drill in the silt, so there are more heavy metals and parasites, which will inevitably lead to these harmful substances entering the human body, and over time will increase the burden on the body, try to avoid it.

The 6 fish species with the most formaldehyde are sharks, tuna, cod, rainbow trout, eels, and abalone.

1. Sharks. Sharks are large marine predators that live in the depths of the ocean and are therefore generally unaffected by pollutants. However, studies have shown that some shark species contain high concentrations of formaldehyde in their bodies.

For example, species such as white sharks, tiger sharks, and bullhorn sharks are all considered fish with higher formaldehyde levels.

2. Tuna.

Tuna is a widely consumed fish that is generally considered to be relatively healthy. However, some studies have shown that tuna may have more formaldehyde levels in their bodies than other fish. This may be due to the fact that tuna** stay in the water for a long time after being caught, or because they live in pollutant-rich waters.

3. Cod. Cod is a common cold-water fish that lives in the deep waters of the Arctic and North Atlantic. While cod is generally considered a relatively healthy food, some studies suggest that they may contain high levels of formaldehyde in their bodies.

4. Rainbow trout.

Rainbow trout is a freshwater fish that lives in rivers and lakes in Europe and North America. While rainbow trout are generally considered a relatively healthy food, some studies suggest that they may have high concentrations of formaldehyde in their bodies.

5. Eel. Eels are a common Japanese food that lives in freshwater or seawater in Asia. While eels are generally considered a relatively healthy food, some studies suggest that they may contain high levels of formaldehyde in their bodies.

6. Abalone. Abalone is a high-grade seafood that lives in the depths of the ocean. Although abalone is generally considered a relatively healthy food, some studies suggest that they may contain high concentrations of formaldehyde in their bodies.
