question 1: how can a bird's nest be distinguished from a fake bird's nest? Is it true if it is hairy? A bird's nest is not necessarily hairy because it can be added with hair. A clean bird's nest without swallow hair is not necessarily fake.

I have many years of experience in bird's nest management, and I grew up in the origin of bird's nest. I know very well that people who have never seen bird's nest at all can't tell the difference between true and false. People who have seen it from the picture can't tell 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.

In the past, many people suggested: smell, touch and burn, remember! Never smell bird's nest! Dried bird's nest is a primary processed product. At present, most of it has not been sterilized (not certified bird's nest under the agreement of the Quality Inspection Bureau). In addition, in order to prevent bacteria from growing more easily after being broken and humidified during transportation, you should be careful when smelling and touching it to ensure that it will not be invaded by bacteria.

after the bird's nest is soaked, it is not necessarily possible to see the swallow hair, and it is not necessarily possible to judge whether it is true or not and what substances are added from touching, smelling and burning. The authenticity of bird's nest is really difficult to distinguish for people who have little contact with bird's nest, but it can be distinguished for people who have frequent contact with 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 111% is added or what methods are used to make bird's nests clean more quickly. Even bird's nest experts can definitely distinguish the quality of bird's nest 111%! Therefore, the most effective way to ensure that the bird's nest is 111% authentic now is to buy the 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 ensure the authenticity.

Question 2: Is the soaked bird's nest hairless? Do you want to have a look at two smells, three pulls, four burns and five stews?

First, look: the real bird's nest should be filiform with clear fibers. Pure bird's nest is not completely transparent, but semi-transparent, whether it is soaked or viewed under the light, because there will be some gaps in the process of artificial hair picking of bird's nest. These gaps are all swallows' fine hair or other impurities, so it is normal to have gaps, and some small fine hairs can be seen, because it is impossible to be absolutely clean by artificial 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 a smooth surface, fiber adhesion and even flake shape, and it will reflect light slightly under sunlight or light, and the swallow cup is thick. Don't be too greedy when buying 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.

2. Smell: Many people think that bird's nest smells tasteless. In fact, the real bird's nest has a taste, which should be said to be 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 in the Yanwu now, so there will be woody smell, and water spraying will be carried out during transportation (this is an industry potential! ), so there will be some musty smell. But generally, it will be OK as long as it is ventilated, and it will not have this taste after soaking. The added bird's nest will emit a chemical smell and a moldy taste. The fake bird's nest will also smell fishy or greasy.

third, soaking: take a small piece of bird's nest and soak it in water. Pure bird's nest will be 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, so it can't be completely soaked for several hours. Moreover, the water turns yellow, and the fibers are in strands, with poor elasticity. It feels woody, hard and astringent, and emits a strong chemical 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. The Martian ash is black, which is the result of protein's burning.

5. Stewing: Of course, it means stewing bird's nest. Generally, it can be stewed in a stewing pot for 31 to 41 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. After the bird's nest is stewed, it becomes a paste, and there are tiny hairy spots in the bowl, which has a musty taste and a hard taste.

VI. Fluorescent examination. Take pieces of bird's nest and observe them under 365cm ultraviolet lamp. The genuine bird's nest is yellow-green or gray-green with purple fluorescence

Other identification methods of 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 price Bai Yan and sold as high-priced blood swallow or yellow swallow. This kind of fake blood swallow and yellow swallow are difficult to distinguish before wet water. But once soaked, it can be recognized. Because the pigment is dissolved in water, the clear water is immediately dyed red or yellow. And after stewing for one or two hours, its texture is soft and rotten, such as Bai Yan, and the red or yellow color is completely ineffective in water. The real blood swallow and yellow swallow, because they are natural colors, will not change color after soaking and stewing. At the same time, due to the rich nutrient and mineral content of blood swallow, the texture of true blood swallow is still cool and solid after long-term 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 for several times, and the fingers will stick with the smell of chemicals. Moreover, the 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 gum-coated bird's nest: soak the gum-coated bird's nest in water and take it out. After about half a minute, rub it with your thumb and forefinger several times, and your fingers will feel sticky and sometimes smell chemical.

Identification method of painted bird's nest:

Painted bird's nest is more common in swallow's nest, which is to coat flour, eggs, rubber powder, paste or other materials with glue

on the surface of inferior swallow's nest, so that the original loose swallow's nest is more tightly intertwined, the weight of swallow's nest can be increased, and the swallow's nest is not easy to break. Identification method of seaweed bird's nest: < P > It is more common in the market of Yan cake or shredded Yan. There is a mixture of true and false, and there is also an artificial bird's nest made of 111% seaweed by bleaching, drying and boiling. The color is solid white, less shiny, thick and hard, and it smells like seaweed. < P > Question 3: Is the bird's nest with hair really true? I can only say that the probability is greater than that without hair. To be exact, there is no bird's nest without hair, but I will be very meticulous in choosing it, and 11,111% of it will not be clean. I am a bird's nest seller, and I am reluctant to eat

Question 4: Can the bird's nest Maoyan on the market be trusted? Will it be fake? How to tell the true and false bird's nest? At present, there are many fake bird's nests in China, which are made of fish and tapioca powder. Even if they are really bleached and glued, they look good and add weight. You can judge whether they are true or false by soaking in water or cooking. In fact, all the products bought by regular pharmacies are branded, and the price of one branded product is hundreds of times higher.

Weak makes an advertisement, this girl makes a bird's nest purchase, and my sister delivers them directly from Indonesian bird's nest manufacturers. They are absolutely authentic, and the price is much cheaper than that in China. You can call me when you buy bird's nest in the future. You can also call me if you have any questions and help you answer them!

Question 5: I bought a 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 on the market, consumers are often deceived when choosing it. Yiyantang exposed some tricks of bird's nest counterfeiting and taught consumers some unique tricks to deal with counterfeiters.

Trick 1: Paint inferior bird's nest with tapioca powder to gain weight

Many consumers will ask merchants to provide bird's nest lamps with smooth surfaces, and think 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" comes 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 the fine hairs in the middle are picked out. However, unscrupulous businessmen take advantage of the public's misunderstanding and apply paints (such as tapioca powder, gelatin powder, eggs, gum, paste, etc.) on the surface of inferior bird's nest cups, which makes them look bright and dense, and increase their weight, thus gaining higher profits. Cassava powder is very crystal clear after soaking in warm water, and its appearance looks very close to stewed bird's nest. Ordinary consumers can't tell the difference at all.

Trick 2: Wet water

Lose weight for no reason after drying. 25

Some consumers will find that the bird's nest has shrunk after buying it and storing it for a period of time, which is actually another trap set by unscrupulous bird's nest merchants. In the market, the transaction price of some bird's nest is about 25% lower than the public price of the industry. Don't think that it is "cheap", because this 25% is exactly the water in the bird's nest. According to the usual size (excluding the extra-thick species), 37.5g bird's nest should have 6 lamps, but only 4-5 lamps after wet water. This is because the merchant added moisture 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 double

bought grass swallows at the price of 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.

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

Maoyan comes from "Dongyan". This kind of swallows are used to building nests with feathers mixed with saliva. Maoyan has weaker water absorption than Guanyan, and its color is darker. After removing impurities, it can be made into shredded swallows, balls and cakes after soaking in water, and its nutritional value is lower than that of Guanyan.

Swallow grass likes to build its nest with weeds mixed with saliva, which contains a lot of impurities, and its bird's nest components are the least, so the price is also the lowest among the three categories. The main manufactured products are shredded swallow and shredded swallow.

There is a layer of netted bird's nest strips on the concave surface of the official swallow cup, and unscrupulous businessmen will replace them with swallows of grass swallows with very similar shapes. The official swallow usually costs 951~1111 yuan/37.5g, while the grass swallow costs only 311 yuan/37.5g.. The profiteering of unscrupulous businessmen can be imagined.

Trick 4: Exaggerate the efficacy

Buy non-existent nutritional value at a high price

Among many species of bird's nest, people generally think that blood swallow is the noblest species, and eating blood swallow has the function of enriching blood. In fact, the efficacy of blood swallows is no different from that of Bai Yan and Huang Yan. The formation of blood swallows is not because of "swallows crying blood", but because the saliva secreted by swallows is red because of the minerals contained in the food they eat. This name is artificially determined.

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

trick five: totally fake

resin seaweed is eaten as bird's nest

At present, some restaurants will send bird's nest desserts to guests to taste after meals, but in fact, they are just making up the number. When cooking official swallows, merchants use resin or bleached seaweed as instant bird's nest or broken swallows to deceive consumers.

question 6: is the bird's nest I have soaked hairless fake? Generally, the less fine-grained bird's nest, the better its quality. According to the current processing technology, it is impossible to remove all the hairs and impurities from the bird's nest, unless it is a synthetic fake bird's nest, and the authenticity of the bird's nest can be judged by looking, touching and soaking.

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

Second touch: The swallow cup of bird's nest (the original shape of bird's nest) is dry and humid, because the swallow cup is too wet, which is not only easy to weigh and mildew.

Third soak: if the bird's nest is soaked for more than 4 hours, it will be a fake bird's nest. The bird's nest pretending to be pigskin is oily and contains oil stains floating on the water surface when soaked. Press it flexibly.

Guidance of Kangmei Health Mall: You need to pay attention to whether the bird's nest is clean or not, 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 to it, most of them are fake.

question 7: is the bird's nest fake? Of course, as we all know in Malaysia, blood swallows are fried by China people, which are all fake, and egg white is painted on the bird's nest to increase the weight. These are all available, but now China has made several policies, and the bird's nest market in the future should be standardized a lot, and people pay more attention to the quality.

Question 8: How to distinguish the authenticity of ready-to-eat bird's nest? How to identify the true and false instant bird's nest: Because many people are afraid of the foam and stew 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 buying 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 gently pulled). The juice is pale white, light yellow or light brown, and the taste is fragrant and sweet. 2. Why don't you buy broken Yan, Yan Jiao, 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 of Yan could be eaten. Is there any remedy?

In fact, 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 directly make broken Yan, Yan jiao, small Yan tiao and so on for sale.

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

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 directly make broken Yan, Yan Jiao, Xiaoyan and so on 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 Yan Jiao, Yan Broken, Yan 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 shops.

Due to the limited natural output, 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 choose other substitutes to avoid being cheap and counterproductive. Especially expectant mothers and babies should pay special attention. Today, when food safety is a problem, we must choose pure bird's nest washed by hand, 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 common bird's nest, it is recommended to rinse it repeatedly with running water after soaking, so as to minimize drug residues. Pregnant women and children are advised not to eat.

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

First, the fake bird's nest is made of tremella (tremella), which is flaky and the liquid is thick, so it is not easy to shake;

second, it is made of seaweed glue and fish skin, which can be faked in appearance, but has poor taste and no rich fragrance of bird's nest.
