What kind of bird s nest to buy I don t understand this

Ordinary white bird's nests will do.

Pay attention to distinguish the real from the fake when buying.

Classification: Guanyan is the best variety.

Specifically, bird's nests are usually classified into the following three levels according to their texture, cleanliness and appearance:

Official swallow: (from "house nest" or "cave swallow") has less impurities, its color is slightly yellow, and it is loofah-like. After adding water, it will become soft, strong water absorption, and can expand seven or eight times, which is the top grade in bird's nest. Because it was only used to pay tribute to the government in the past, it was called "Guanyan".

Bird's nest: (only produced in "cave swallow") Bird's nest has weaker water absorption than official bird's nest, and the color is darker, and it can be made into bird's nest silk, bird's nest balls and bird's nest cakes after removing impurities and soaking in water. Because of its more processing process, its nutritional value and price are lower than those of Guan Yan.

Grass Swiftlet: (Produced from "House Nest" or "Cave Nest") Grass Nest contains a large number of impurities, and its bird's nest composition is the least among the three types, and the price is the cheapest. It is more suitable for tasters or long-term eaters who like to mix and eat with swallows.

Distinguish the real from the fake: the genuine product has irregular hairy texture.

Real bird's nest: with a little hair, irregular texture, the best bird's nest can grow up to 8 times larger after soaking. After the real bird's nest is boiled and stewed, some melt and some do not, and the taste is also refreshing and smooth.

Fake bird's nest: It is mainly divided into the following categories.

First, dyed bird's nest. It is dyed with low-priced white bird's nest into ** yellow bird's nest or blood bird's nest. However, because the pigment is soluble in water, the dyed bird's nest will appear in its original form once it is soaked.

Second, add "material" bird's nest. There are many unscrupulous traders in the market who apply tapioca flour, fish gelatin powder, eggs, gums, paste, etc. to the surface of low-quality bird's nest cups to make them look brighter and thicker, and increase their weight to achieve higher profits.

Third, all fake bird's nests. Profit from resin or bleached seaweed, etc., as instant bird's nest or bird's nest crumble.

Clause. The second and third types of fake bird's nests are not easy to identify in appearance, so be sure to pay attention to the brand's reputation when buying.

Advantages and disadvantages: Pretty bird's nest is clean and dry.

There are four key tips for choosing a good bird's nest: first, the difference between the weight of the bird's nest and that when it is dried, that is, the bigger the "hair", the better, which means that it is eaten. The "hair" of the general official swallow is 6 8 times; secondly, clean, that is, the less fine hairs and impurities, the better; Thirdly, the shape of the bird's nest should be obvious, and the thinner the head and feet at both ends, the better; Finally, it is dry and light, and the one with less water content is the best quality.

How to choose bird's nests.

Bird's nest has always been a precious ingredient, and only dignitaries can afford to enjoy it after ancient times, but now with the development of the economy, people's consumption level is getting higher and higher, and more and more people can afford to eat bird's nest, but the problem of mixed bird's nest and uneven quality is more serious. Therefore, how to choose a good quality bird's nest becomes the key.

When choosing bird's nest, the first thing to do is the structure of the bird's nest, a good bird's nest is composed of a trace of filaments, if it is a sheet structure, it is a fake bird's nest. Then there is the smell, if there is a fishy smell and a greasy smell, it is a fake. In addition, soak the bird's nest for 6-7 hours, take a few bird's nest filaments by hand, and then pull it, if the elasticity is poor, it will break when you pull it, and if it becomes a paste after rubbing it by hand, it is also a fake.

Bird's nest is a precious ingredient, and the appearance of vermicelli looks similar to bird's nest, so there are many people on the market who use vermicelli to pretend to be bird's nest, and the fans for a few dollars are sold as bird's nest, and the economic benefits are simply scary. So we must be smart consumers, don't be fooled by those unscrupulous merchants.

1. Comparison by texture.

There are probably the following criteria for evaluating the grade of bird's nest:

1. The "dense, fine, and sparse" of bird's nest cups are distinguished, and the denser ones are classified as top-level bird's nests, and the sparse ones are second-class. Generally, the compact fiber of the complete fiber is the first grade, and the fiber of the incomplete shape is not compact as the second grade.

2. According to the division of the bowl shape, it is better to have a complete and uniform bowl shape.

2. Comparison according to the type of bird's nest.

According to the quality of bird's nest, it is divided into official bird's nest, hairy bird's nest, and grass bird's nest.

1. Official bird's nest: The bird's nest in the first stage with a complete shape and few impurities is usually called "official bird's nest" and "tribute bird's nest". This bird's nest is the most nutritious, with few impurities and a good taste. Tradition also has a way of calling the first high-quality white bird's nest as the official bird's nest.

2. Bird's nest: a bird's nest containing more bird's nest, or second and third bird's nests. The nutritional content is not as good as that of the official swallow, and there are many impurities, which is not easy to handle.

3. Grass swiftlet: a kind of bird's nest built in the grass, mixed with a large number of grass clippings, the worst quality.

3. Compare according to the color of bird's nest.

Bird's nest can be divided into white bird's nest and blood bird's nest according to its color. In fact, there is a lot of controversy about comparing the quality of bird's nest with **. A lot of data shows that the bird's nest unique ingredient content of white bird's nest in the first stage is the highest, and the difference between the two is not very large.

However, due to the fact that the production of blood bird's nest is very scarce and has a special texture and taste, sometimes the market ** is slightly higher than that of white bird's nest.

1. First of all, taste.

High-quality bird's nest will have the saliva smell of swallow and a little fishy, this taste will disappear after stewing, replaced by a faint fragrance, if the fishy smell of bird's nest is too strong, it means that it is not high-quality bird's nest.

2. The second is "hair".

For the same weight of bird's nest, the greater the weight after soaking, the better the quality. This is called "hair" in the industry, which means that the greater the weight after soaking, the better the hair.

3. Then there is density.

Generally, when choosing dried bird's nest, the main thing to look at is the density of the filament, if the bird's nest filament is fine, it seems that there is no void, in fact, the light transmittance is high, this kind of bird's nest has a large head after soaking, and the quality is good.

1. Bird's nest, also known as swallow vegetables, swallow roots, and swallow vegetables, refers to the saliva secreted by some swifts of the swift family of the order Swift family and several swiftlets of the genus Swiftlet, and then mixed with other substances to build a nest.

2. Bird's nest can be divided into two kinds according to the place of nesting: "house nest" and "cave nest", cave nest has different colors due to its influence by minerals, there are white bird's nest, yellow bird's nest, red bird's nest, and house bird's nest only has a color of ivory white. Bird's nest is one of the traditional and precious foods that has been eaten in China since the Ming Dynasty. The so-called "blood bird's nest" on the market is said to be made by artificially bred house nests through the "guano fumigation method".

1. Look at the origin of bird's nest: Under normal circumstances, bird's nest produced in Indonesia and Malaysia is better.

2. Look at the dryness and water content of the bird's nest: the bird's nest is drier to the touch, and the less water content is better.

3. Look at the completeness, fullness and cleanliness of the bird's nest: it is better to have a complete, full and clean bird's nest.

4. Look at the type and color of bird's nest: under normal circumstances, it is better to take bird's nest, white bird's nest is better, blood bird's nest is better to be dark red, and the less feathers entrained in bird's nest, the better.

5. Look at the shape and transparency of bird's nest: under normal circumstances, bird's nest should be a filamentous structure, and the structure composed of pieces is generally not a real bird's nest; And the better bird's nest is not completely transparent after soaking or under the light**, but translucent.

6. Smell the smell of bird's nest: Bird's nest has a fragrant fragrance, but there is no strong smell. Those with a peculiar smell and a fishy or greasy smell may be fake.

7. Feel the elasticity of the bird's nest after soaking: take a small piece of bird's nest and soak it in water, and pull it with silk after it is soft, the elasticity is poor, and it may be a fake if it is broken; If you rub it with your fingers, it may be a fake if it has no elasticity and it becomes a paste.

8. Look at the color change of bird's nest after soaking: Normally, the discoloration of blood bird's nest and yellow bird's nest after soaking may be fakes.

9. Look at the sound and sparks after the bird's nest burns: Use fire to ignite the dried bird's nest slices, the real bird's nest generally does not produce crackling sparks, but only has a slight sound, and melts into bubbles, no smoke odor. Fake bird's nests have bursting, sparkling sounds, black smoke, and a scorching smell.

10. Look at the morphological changes of the bird's nest after soaking in water: the real bird's nest is soft and swollen, crystal clear, elastic under light pressure, and retractable by hand. Fake bird's nests generally have oily substances floating on the surface of the water, which are easy to loosen, sponge-like and opaque.

11. Look at the touch of bird's nest: real bird's nest is hard and brittle, and the section is slightly keratin-like, while fake bird's nest is generally crispy and fragile.

The selection of bird's nest should be seen, smelled, touched, burned, and fired.

1. Take a look. Bird's nest should be a filamentous structure, and it is not a real bird's nest composed of a piece structure; Bird's nest is not completely transparent, but translucent, whether it is soaked or under the light**.

2. Second smell. Bird's nest has a unique fragrant aroma but no strong smell. Those with a special smell, fishy smell or greasy taste are fakes.

3. Three touches. Take a small piece of bird's nest and soak it in water, take the silk strip and pull it after it is soft, the elasticity is poor, and the one that breaks when pulled is a fake; Rub the base Zheng code with your fingers, and those that can be rubbed into a paste without elasticity are also fakes.

4. Four burns. Ignite the dried bird's nest slices with fire, if it is a real bird's nest, it will never produce any violent splashing sparks.

5. Five water and fire identification.

Good bird's nest has a "hair" after water immersion, which can be expanded by 7 to 8 times, and the water immersion is hard or faded, which is fake and shoddy.

In fact, if you eat it yourself, it is enough to eat some of the most ordinary bird's nests, which are the same in terms of nutritional value, but they are not so good-looking, and the soaking rate and taste are very good.

Here's how to tell the difference between a bird's nest and a fake:

1. Look: See if there are gaps in the bird's nest (due to the dehairing process, it is impossible for the bird's nest to be free of gaps, and the general gap-free ones are more serious gluing); whether the soaking rate is between 7-9 times (it is not normal for the soaking rate to be too low or too high, because the soaking rate of some adulterated substances is far from the bird's nest); If each one is the same, white, and very beautiful, it is likely to be bleached or fake (bird's nest is natural, it is impossible to be very perfect, and it is impossible for each one to be the same); Looking at the light or under a magnifying glass, the real bird's nest should be able to clearly see a trace of lines.

2. Smell: Bird's nest has a unique fragrance, but no strong smell. Those with a special smell and a fishy or greasy smell are fakes.

3. Touch: Real bird's nest is formed from swiftlet saliva, which has an obvious rough hand feeling to the touch, while fake bird's nest is very smooth to the touch. 4. Bubble:

Bird's nest will expand after soaking in water, and after being soft, take the silk strip and pull it, the elasticity is poor, and it will break when it is pulled. Rubbing with your fingers, if you don't have elasticity to make a paste, it's also a fake; After soaking in water, the water quality of real bird's nest is still clear, while fake bird's nest has other ingredients that cause turbidity when dissolved in water.

I hope it can help you, and if there is anything you don't understand, you can ask me.

The denser the fiber is selected, the larger and more complete the appearance.

1. The denser the fiber, the better.

2. Beware of paint processing.

Most of the high-quality bird's nests have undergone a plucking process, and there are obvious gaps between the silks. Although it is said that the denser the bird's nest, the better, but it is definitely not airtight.

5. A small amount of young hairs.
