Do you have fake bird's nest?

Question 1: How can bird's nest be divided into true and false? Is it true if there is hair? Bird's nest is not necessarily hairy, and it is not necessarily true, because hair can be added. A clean bird's nest without swallow hair is not necessarily fake.

Having many years' experience in managing bird's nest and growing up in the origin of bird's nest, I know very well that it is impossible for people who have never seen bird's nest to tell the true from the false. People who have seen it from the picture can't tell the truth from the truth when they see the real thing. Therefore, the best way to distinguish the authenticity of bird's nest at present is to send it to the quality inspection bureau for inspection.

Many people used to suggest: smell, touch, burn, remember! Never smell the bird's nest! Dried bird's nest is a primary processing product. At present, most of them have not been sterilized (not the bird's nest certified by the Quality Inspection Bureau). In addition, in order to prevent bacteria from breeding more easily after being damaged and damp during transportation, you should be careful when smelling and touching to ensure that it will not be invaded by bacteria.

After the bird's nest is soaked, you may not be able to see the swallow hair, and you may not be able to judge whether it is true or not and what substances have been added from touching, smelling and burning. The authenticity of bird's nest is really difficult to distinguish for people who rarely contact bird's nest, but it can be distinguished for people who often contact bird's nest. At present, many bird's nests on the market are actually real. The question is what additives are used in the processing, how much 100% is added or what methods are used to make bird's nest clean faster. Even bird's nest experts can definitely tell the difference between good and bad bird's nest! Therefore, the most effective way to ensure the authenticity of bird's nest 100% is to buy traceable bird's nest from Malaysia, which has signed an agreement with the Quality Director Bureau of China. This is the only way for the two countries to guarantee authenticity.

Question 2: Is it false that the soaked bird's nest has no hair? Do you want to watch two smells, three pulls, four cooks and five stews?

First, look: true bird's nest should be filamentous structure with clear fibers. Pure bird's nest is not completely transparent, but translucent, whether it is soaked or watched under light, because some gaps will be formed in the process of artificial hair picking. These gaps are all fine hairs of swallows or other impurities, so it is normal to have gaps, and some fine hairs can be seen, because it is impossible to be absolutely clean by manual hair picking. At the same time, the texture of normal bird's nest should be a little bit. However, the glued bird's nest has smooth surface, fiber adhesion, uniform sheet shape, slight reflection in sunlight or light, and thick bird's nest cup. Don't be too greedy to buy bird's nest. The color should be light gray or yellowish. It is normal to have different shades of color, which is the color of bird's nest after natural oxidation in contact with air.

Second, the smell: Many people think that bird's nest smells tasteless. In fact, the real bird's nest has a taste. It should be said that it is a faint fishy smell. After all, it is made of swallow's saliva. There is also a faint woody smell, because most of the bird's nests are now in Yanwu, so there will be woody smell, and water will be sprayed during transportation (this is the industry potential! ), so there will be some musty smell. But it's usually OK as long as it's ventilated, and it won't smell like this after soaking. The added bird's nest will give off a chemical smell and moldy taste. Fake bird's nest can also have a fishy smell or greasy feeling.

3. Soak: Take a small piece of bird's nest and soak it in water. Pure bird's nest is soaked in half an hour, the water in the bowl is still clear, and the bird's nest filaments are clear, smooth and elastic; However, the glued bird's nest fiber has been calcified and cannot be completely soaked for several hours. Moreover, water turns yellow, fibers become strands, and their elasticity is poor. It feels woody, hard and astringent, emitting strong chemicals and musty smell. Rubbing with your fingers, those that can be rubbed into a paste without elasticity are also fakes. 4. Burning: If the dried bird's nest is lit with fire, it will never produce any violent splash. Mars ash is black, which is the result of protein burning.

Stewed: Of course, it means stewed bird's nest. Usually stew in a saucepan for 30 to 40 minutes. The stewed bird's nest is translucent, the silk strips are still clear, it smells rich in protein, and the taste is smooth and tender. The stewed bird's nest becomes mushy after being added, and there are tiny hair spots in the bowl, which have a musty taste and a hard taste.

Six, fluorescence inspection. Take bird's nest slices and observe them under 365 cm ultraviolet lamp. Genuine yellow-green or gray-green, with purple fluorescence.

Other identification methods for making fake bird's nest

Identification method of dyed bird's nest:

The so-called dyed bird's nest is mostly dyed red or yellow with low-priced Bai Yan and sold as high-priced blood swallow or yellow swallow. This kind of fake blood swallow is difficult to distinguish from Huang Yan before wet water. But once soaked, you can recognize it. Because the pigment dissolves in water, the clear water is immediately dyed red or yellow. And after stewing for an hour or two, its texture is soft and rotten like Bai Yan, and red or yellow is completely ineffective in water. The real blood swallow and yellow swallow, because they are true colors, will not change color after soaking and stewing. At the same time, because the blood swallow is rich in nutrients and minerals, the true blood swallow is still cool and solid after a long period of stewing.

Identification method of bleached bird's nest;

Soak the bleached bird's nest in water and take it out. After about half a minute, rub it with your thumb and forefinger a few times. Fingers will stick to the smell of chemicals, and bleached bird's nest will not rise much after stewing, which is easy to water and has no natural egg white smell.

Identification method of coated bird's nest: soak the coated bird's nest in water and take it out. After about half a minute, rub your thumb and forefinger several times, and your fingers will feel sticky and sometimes smell chemicals.

Identification method of painted bird's nest;

Colored bird's nest is common in cup-grade bird's nest, which is made by coating flour, eggs, rubber powder, paste or other glue on the surface of inferior cups.

The quality of the material makes the original loose swallow cup woven more tightly, which can increase the weight of the swallow cup and is not easy to break. Identification method of seaweed bird's nest;

More common in the market of Yan cake or Yan silk. There are real ones, and there are artificial bird's nests made of 100% seaweed after bleaching, drying and boiling. The color is pure white, not very shiny, thick and hard, with seaweed flavor.

Question 3: Is the long-haired bird's nest really true? It can only be said that the probability is really greater than that of hairless bird's nest. To be exact, there are no hairless bird's nests, but there are few carefully selected ones, and 100,000% are not clean. I sell bird's nest, and I can't bear to eat less hair. I wanted to choose one for two whole days, but I still saw a lot, so I gave up.

Question 4: Can Mao Yan trust the bird's nest on the market now? Could it be fake? How to tell the authenticity of bird's nest? At present, there are many fake bird's nests in China, which are made of fish and cassava flour. Even if it is really bleached and glued, it looks good and adds weight. You can tell whether they are true or not by soaking in water or cooking. What regular pharmacies buy is actually OEM, and the price of an OEM is hundreds of times higher.

Weak advertising, this girl does * * * bird's nest purchasing, and elder sister delivers it directly from Indonesia bird's nest factory, which is absolutely authentic, and the price is much cheaper than that in China. You can come to me when you buy bird's nest, and you can come to me if you have any questions and help you answer them!

Question 5: I bought bird's nest, but it feels fake. Where should I go to identify the authenticity? In view of the uneven quality of bird's nest in the market, consumers are often deceived when choosing. Yi Yantang exposed some tricks of bird's nest fraud and taught consumers some tricks to deal with counterfeiters.

Trick 1: draw.

Weight gain of inferior bird's nest coated with cassava flour

Many consumers will ask merchants to provide bird's nest lamps with smooth surfaces, thinking that such bird's nest is a good bird's nest. In fact, it is this misunderstanding that gives unscrupulous businessmen an opportunity, and the so-called "painted bird's nest" came into being.

In fact, real experts know that after the bird's nest is made into a lamp, there are many small holes on the surface because of the fine hair in the middle. However, unscrupulous businessmen use the misunderstanding of the public to smear pigments (such as cassava flour, Geely flour, eggs, gum, paste, etc.). ) on the surface of inferior bird's nest cup, it looks bright and dense, increases weight, and thus obtains higher profits. Cassava powder is very crystal clear after soaking in warm water, and looks very close to stewed bird's nest. Ordinary consumers simply can't tell the difference.

Trick 2: wet water

Unnecessary weight loss after drying 25

Some consumers will find that the bird's nest has shrunk after buying it for a period of time, which is actually another trap set by illegal bird's nest merchants. In the market, the transaction price of some bird's nest is about 25% lower than the open price of the industry. Don't think it is "cheap", because this 25% is just the water in the bird's nest. According to the usual size (excluding super-thick species), there should be 6 bird's nests with 37.5g, but only 4-5 after wet water. This is because the merchants added water to the bird's nest after purchasing. Therefore, if experienced buyers find that it is wet bird's nest after inspection, they will ask for 75% of the original price, and most inexperienced consumers will become "big heads".

Trick 3: Body body double

Bought grass swallows at the price of buying official swallows.

It is understood that the types of bird's nest are divided into three types according to the classification of swallows: official swallows, hairy swallows and grass swallows.

Yan Guan is used to building nests with pure saliva, so there are few impurities and the color is light yellow, like loofah. After adding water, it becomes soft, has strong water absorption and can expand seven or eight times. It is the top grade of bird's nest.

Mao Yan comes from "Dongyan". This swallow is used to nesting with feathers mixed with saliva. Mao Yan's water absorption is weaker than Yan Guan's, and its color is darker. After removing impurities, it can be made into shredded Yan, meatballs and cakes after soaking in water, and its nutritional value is lower than that of Yan Guan.

Grass swallows like to nest with weeds mixed with saliva, which contains a lot of impurities, and bird's nest has the least components, so the price is also the lowest among the three categories. The main products are Yansi and Yansi.

The concave surface of the official swallow cup has a layer of netted bird's nest strips, and unscrupulous merchants will replace it with grass swallows with very similar shapes. The price of official swallow is usually 950~ 1 100 yuan /37.5g, while the price of grass swallow is only 300 yuan/37.5g. The profiteering of unscrupulous businessmen can be imagined.

Trick 4: Exaggerate the curative effect

Pay a high price for non-existent nutritional value.

Among the many varieties of bird's nest, it is generally believed that blood swallow is the noblest variety, and eating blood swallow has the function of enriching blood. In fact, the efficacy of blood swallow is no different from that of Bai Yan and Huang Yan. The formation of blood swallows is not because swallows cry blood, but because the food they eat contains minerals, so the saliva secreted by swallows is red. The name is artificially determined.

Wu Hongsen revealed that, in fact, the wholesale prices of blood swallow, Bai Yan and Huang Yan by bird's nest merchants are the same. It is only because the number of blood swallows is small that consumers mistakenly think it is particularly precious, so merchants will "follow the trend".

Trick 5: Full leave

Resin seaweed is eaten as bird's nest.

At present, some restaurants will give guests bird's nest desserts after meals, but they are just making up the numbers. Merchants cheat consumers by using resin or bleached seaweed as ready-to-eat bird's nest or broken swallow when cooking official swallow.

Question 6: Is the hairless bird's nest I soaked fake? Generally, the finer the bird's nest, the better the quality. According to the current processing technology, it is impossible to remove all the hair and impurities from bird's nest, unless it is a synthetic fake bird's nest, and the authenticity of bird's nest can be judged by looking, touching and soaking.

Take a look: Is the bird's nest clean, with few impurities and tight fibers?

Two touches: the swallow cup of bird's nest (the prototype of bird's nest) is dry and wet, because the swallow cup is too wet, which is not only easy to weigh, but also easy to mold.

Three bubbles: the bird's nest soaked for more than 4 hours is a fake bird's nest. The bird's nest posing as pigskin is oily in water and contains oil stains. Real bird's nest will be 6-8 times larger after soaking in water, and it will be elastic when pressed.

Guide of Kangmei Health Mall: You need to pay attention to whether the bird's nest is clean, and the bird's nest with less fine hair is better, but if the bird's nest has no impurities and hair at all, you should pay attention, most of them are fake.

Question 7: Is the bird's nest fake? Of course, we all know that Malaysian blood swallows are fried by China people, and they are all fake. Brush egg white on the bird's nest to increase the weight. There are all these, but now the country has made several policies, the future bird's nest market should be standardized, and people pay more attention to quality.

Question 8: How to tell the true and false instant bird's nest? How to distinguish true and false instant bird's nest: Because many people are afraid of the soaking and stewing of bird's nest, many people now choose to buy bottled instant bird's nest (concentrated bird's nest) directly. But the bird's nest in the bottle is more difficult to identify, so fakes are very rampant. When you buy canned bird's nest, shake it gently first. The real bird's nest can shake with the shaking of the bottle, and it is silvery white, transparent, crystal clear and elastic (it will stretch when pulled gently). The juice is pale white, light yellow or light brown and tastes sweet. Why don't you buy Broken Swallow, Yanjiao and Yan Bing? Many friends asked about the detailed processing process of ordinary bird's nest and inferior bird's nest, and some friends asked if some very cheap pieces, cakes, horns and strips could be eaten. Is there any remedy?

In fact, there are many forms of "black-hearted" bird's nest, some are made into different shapes of Yan cakes, and many inferior ones are directly made into broken Yan, Yan glue and Xiao Yan strips for sale.

Inferior bird's nest is made by soaking inedible bird's nest raw materials (grass swallow, hairy swallow and heavily polluted official swallow) in chemical solution to achieve the effects of bleaching, deodorization and depilation, and then gaining weight by hanging pulp and other methods.

There are many forms of "black-hearted" bird's nest, some of which are made into different shapes of Yan cakes, and many inferior ones will be directly made into broken Yan, Yanjiao and Xiaoyan for sale.

These dried bird's nest products not only have no benefits to human health, but also contain a lot of heavy metal residues, which seriously threaten health, especially the damage to pregnant women and infants is irreversible.

The products of inferior bird's nest are mostly presented in swallow gum, broken swallow, swallow cake, bird's nest products and bird's nest ingredients in restaurants and hotels, and the sales channels are mainly concentrated in wholesale markets and online stores.

Due to the limited natural production, bird's nest is still a scarce high-end tonic for a long time. It is suggested that friends with limited economic conditions and price sensitivity should buy other substitutes to avoid being greedy and cheap, which is counterproductive. Especially expectant mothers and babies should pay special attention. Today, when food safety is a problem, we must choose pure hand-cleaned bird's nest, without using a drop of chemicals or adding a gram of non-bird's nest substances, in order to play a nourishing role. After buying inferior and ordinary bird's nest, it is recommended to rinse it repeatedly with running water after soaking to minimize drug residues. Pregnant women and children are advised not to eat it.

There are several kinds of fake bottled concentrated bird's nest:

First, tremella fuciformis (tremella fuciformis) is flaky, and the liquid is viscous, so it is generally not easy to shake;

Second, it is made of seaweed glue and fish skin, and its appearance can be faked, but its taste is poor, without the rich fragrance of bird's nest.

Question 9: How to tell the authenticity of bird's nest? Method 1: Draw a bird's nest.

The inferior bird's nest is smeared with cassava powder to gain weight. Many consumers think that the bird's nest with smooth surface is a good bird's nest. It is this misunderstanding that gives unscrupulous merchants an opportunity, and painted bird's nest comes into being. The Bird's Nest is a bird's nest built in Jin Siyan. It is rich in protein's saliva and overlapped in strips. It takes about two and a half months before and after nesting, and it is inevitable that there will be falling feathers or other impurities between the strips of bird's nest. After the bird's nest is taken off and made into a lamp, there are many small holes on the surface because there are fine hairs and impurities in the middle. This kind of bird's nest is not very beautiful. Compared with the best official swallow, there are fewer impurities. Unscrupulous businessmen take advantage of consumers' misunderstanding and smear pigments (such as cassava flour, fish glue, eggs, gum, paste, etc. Fake the surface of inferior bird's nest cup to make the bird's nest cup look bright and dense, increase the weight and get higher profits. Cassava powder is also very crystal clear after soaking in warm water, and looks very close to stewed bird's nest. Ordinary citizens simply can't tell the difference.

Method 2 of bird's nest fraud: wet water.

Some citizens bought dried bird's nest, stored it for a while, and then lost 25% for no reason. The shrinking of bird's nest is actually another fraud trap set by illegal bird's nest merchants. In the market, the transaction price of some bird's nests is 25% lower than the open price of the industry. Consumers should never feel cheap, because low prices are just water in the bird's nest. According to the usual bird's nest size (excluding super-thick species), 37.5g bird's nest should have 6 cups (6 grams on average), but only 4-5 cups (7-9 grams on average) after wet water. This is because the merchants added water to the bird's nest after purchasing. Experienced buyers will charge 75% of the original price if they find it is wet bird's nest after inspection, while inexperienced consumers will mostly become suckers. What's more, the surface of bird's nest is sprayed with colorless and odorless glue similar to hair gel. Once the glue sets, the surface of bird's nest seems dry to the touch. In fact, the water contained in bird's nest is completely sealed by spraying glue, and the profit of this bird's nest is amazing.

Method 3 of bird's nest fraud: double body.

Bought grass swallows at the price of buying official swallows. The species of bird's nest can be divided into three types according to swallows and nesting materials: official swallows, hairy swallows and grass swallows. Official swallows are used to building nests with pure saliva, so there are few impurities and the color is yellow, like loofah. After adding water, it becomes soft, has strong water absorption and can expand seven or eight times. It is the top grade of bird's nest. Mao Yan is produced in Dongyan. This swallow is used to nesting with feathers mixed with saliva. Mao Yan is weaker in water absorption and darker in color than Yan Guan. After removing impurities, it can be made into shredded Yan, meatballs and cakes after soaking in water, and its nutritional value is lower than that of Yan Guan. Grass swallows like to nest with weeds mixed with saliva, which contains a lot of impurities, and bird's nest has the least components, so the price is also the lowest among the three categories. The main products are Yansi and Yansi. The concave surface of the official swallow cup has a layer of netted bird's nest strips, and unscrupulous merchants will replace it with grass swallows with very similar shapes. Official swallows usually cost 950~ 1 100 yuan/37.5g (25~30 yuan/g), while grass swallows only cost 300 yuan/37.5g (8 yuan/g). The profiteering of unscrupulous businessmen can be imagined.

Identification method of bottled concentrated bird's nest (instant bird's nest);

Because many people are afraid of the foaming and stewing of bird's nest, many people now choose to buy bottled instant bird's nest (concentrated bird's nest) directly. But the bird's nest in the bottle is more difficult to identify, so fakes are very rampant. But you can make a preliminary identification from the following methods.

Top-grade instant bird's nest, crystal clear in color. After tilting the ready-to-eat bird's nest bottle at 45 degrees, there is not much water, and the scooped bird's nest is crystal clear and delicate. High-quality ready-to-eat bird's nest (Bai Yan) has unique bird's nest collagen, which is rich in flavor after opening a bottle. Because Jin Siyan eats algae and insects on the seashore, the stewed blood swallow is not as rich as Bai Yan, but the mineral content is higher. The instant bird's nest stewed by exquisite craftsmanship has a smooth and elastic taste. Natural ready-to-eat bird's nest should be marked without preservatives and additives. When you buy canned bird's nest, shake it gently first. The real bird's nest can shake with the shaking of the bottle, and it is silvery white, transparent, crystal clear and elastic (it will stretch when pulled gently). The juice is pale white, light yellow or light brown and tastes sweet.

There are several kinds of fake bottled concentrated bird's nest: first, > >;

Question 10: Dear gods, is it fake to buy bird's nest in Malaysia? It is true to buy bird's nest in Malaysia. Malaysia strictly controls bird's nest. Malaysia is the second largest exporter of bird's nest in the world and the only country in the world where bird's nest has gone abroad without flu. Because it is the place of origin, raw materials and finished products can be obtained at reasonable prices everywhere, and there is no need to falsify. However, I don't know that there are some products from other countries on the market, and the processing technology or other substances may not meet the requirements of Malaysia. We must be cautious when buying.
