How is bird s nest formed How does bird s nest come about?

The nest is made up of saliva secreted by some swifts of the Swift family and several species of swiftlets of the genus Swiftlet, mixed with other substances. 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".

The main production areas of bird's nest range from the Philippines in the east to the caves on deserted islands near the coast of Myanmar in the west, and most of them are in Southeast Asian waters such as Indonesia, Malaysia, Sandakan, Singapore and Thailand, as well as the islands of the South China Sea.

1. Bird's nest is a kind of bird called "swiftlet", which is cemented by mixing their feathers and saliva with moss, seaweed and soft plant weaving.

2. Swiftlets have well-developed mucus glands in their throats, which can secrete abundant saliva, and their saliva can be condensed into solids in the air, so swiftlets mainly use it to build nests as hiding places.

3. Bird's nest is rich in sugars, organic acids, free amino acids and characteristic substances - sialic acid.

4. The "blood bird's nest" in the bird's nest is made of the "brown-tailed swiftlet", which may drink different water quality, or because the feed may contain minerals and other factors, causing its saliva to appear red, so the "blood bird's nest" nest is built, which is regarded as a treasure in the bird's nest.

Bird's nest is a tonic with high nutritional value, **expensive, and real blood bird's nest is relatively rare. The general bird's nest is white and is formed by the saliva secretion of the swallow, while the red bird's nest is due to the special living environment of the swiftlet, the bird's nest is on the mineral-rich mountain wall, and the iron substance seeps into the saliva secreted by the swallow and turns red. Most of the red bird's nests on the market are dyed, so they should be identified.

Bird's nest is simply formed by the long-term accumulation of swallow's saliva.

Wellness is becoming more and more popular, how is bird's nest formed?

1. Swiftlets belong to the swift family, migratory bird habits, fly from Siberia and other places to the natural caves along the coast of Southeast Asia from December to March of the following year to reproduce.

2. Swiftlets are several times smaller than the common swifts in our country, and the swiftlets have developed mucus glands in their throats, which can secrete rich saliva, and its saliva can be condensed into solid in the air. Swiftlets nest in February-March, May-September every year, it takes about 20 days to build, the bird's nest is generally like a half-moon shape, the base is thick, the wall is thin, the periphery is neat, and the internal capsule is like a net-like structure.

3. Eggs are laid in March-April and June-October every year, and it generally takes about 3 months to hatch and nurse the little swallows to grow up and leave the nest.

4. At this time, the bird's nest farmer can pick the bird's nest, and after the bird's nest is picked, it also needs to go through complex processes such as picking, air drying, sterilization, inspection, and packaging before it can be made into edible bird's nest for sale.

Bird's nest is a nest made of saliva by swiftlets endemic to Southeast Asia.

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

Bird's nests can be divided into two types: "house nest" and "cave nest", cave nest has different colors due to its influence on minerals, there are white nests, yellow nests, red nests, and house nests only have one color, ivory white. Bird's nest is one of the traditional and precious foods that has been eaten in China since the Ming Dynasty.

What are the types of bird's nest?

According to the color can be divided into white bird's nest, yellow bird's nest, gray bird's nest and blood bird's nest, the first bird's nest is the swiftlet throat has a very developed mucus gland secretion of saliva in the air condensed into a solid formation, is the swiftlet group feeding insects, seaweed, silverfish and other substances after digestion, spit into the bird's nest, colored, so it is white early, also called the official swallow, the whole bird's nest is hot and white, this white is natural white and white with a little yellow!

Yellow morning, the whole bird's nest or most of the bird's nest polarized color, this is the natural principal, the bird's nest picked from the cave also has some uneven brownish-red, blood-colored, brown or brown-yellow lack of wheel color, and the bottom color is darker, the middle and edge are lighter, it should be clarified that this color does not come from the blood in the swallow's mouth, the reason for its formation is mainly believed to be the result of the combined action of the bird's nest environment such as air, humidity, rocks, etc.

Blood bird's nest, especially from the nesting swallow cave wall in the environment where swallows live, contains a high amount of iron to penetrate into the bird's nest, so the bottom of the bird's nest is maroon-red, this part of the bird's nest is called blood bird's nest, it is generally believed that the blood bird's nest is rich in minerals, and the nutritional value is higher than that of white bird's nest, but not all minerals are beneficial to the human body.

What is the composition of bird's nest and how is it formed, and the explanation of how bird's nest is formed is as follows

First of all, we need to understand what bird's nest is. Bird's nest, also known as bird's nest or bird's nest vegetable, is a nest made of some swiftlets or some swifts of the swift family with a large amount of saliva secreted by them mixed with down feathers, Bize seaweed and other substances. In layman's terms, bird's nest is actually a nest built by swiftlets.

Note that it is not comparable to our traditional Chinese nest nest, which is made of mud and weeds. Swallows nest three times a year Suihui stove, all in order to lay eggs to welcome the arrival of small life, each nest only lives once, when the little swallow grows to be able to fly when the nest is abandoned, the swallow nests for about 45 days, 7 to 10 days to lay eggs, with about 15 days to hatch eggs, born of the baby swallow will fly away after 45 to 50 days. This period of time before and after a total of 11 guesses 10 to 120 days, the bird's nest picking work will be carried out after the swallows fly away, after the bird's nest is picked, but also through steaming, soaking, impurities, hair, drying and other complex processing to make the finished bird's nest.

Bird's nest can be divided into three types due to different collection times: 1. White bird's nest: it was listed as a tribute in ancient times, so it is also called official bird's nest; 2. Mao Yan; 3. Blood swallow.

Bird's nest is the part of the nest built by swift swifts and a variety of swallows of the same genus with saliva and down feathers after deep processing. Do you know how bird's nests are formed? I have compiled the formation principle of bird's nest here for your reference, and I hope you will gain something in the process of reading!

Bird's nest is a nest made by swallows, but this swallow is not the swallow we commonly see nesting under the eaves. Bird's nest is built by a kind of swallow, they belong to the swift family, called "swiftlet" (specifically refers to the saliva secreted by some swifts of the swift family of the swift family and several swiftlets of the genus swiftlet, and then mixed with other substances to build a nest, the nest is half-moon-shaped, shaped like a human ear, with a diameter of 6-7 cm, a thick base, a thin profile, and a weight of about 10-15 grams. The periphery of the bird's nest is neat, and the interior is rough, like a network of loofahs.

The whole bird's nest is white and crystalline, full of elasticity, attached to the rocky cliffs.

A bird's nest called swiftlet is made from moss, seaweed and soft plant weaves mixed with their feathers and saliva as a hiding place. The swallow's throat has well-developed mucus glands, and the saliva secreted by it can be solidified in the air, which is the main material for their nesting.

The nests made by young swiftlets are rough due to their lack of nesting experience, containing impurities and feathers. Mao Yan is used to build a nest with feathers mixed with saliva, and grass swallow likes to build a nest with weeds mixed with saliva, so it contains a lot of impurities, the color is dark, the transparency is poor under the light, and the water absorption is weak.

First, the place of origin should be fixed: the place where swiftlet grows affects the quality of bird's nest production, the production area is industrially developed, the darker the bird's nest produced by serious air pollution, the more impurities such as dust, the higher the rainwater and forest coverage area of the production area, the better the bird's nest head and the higher the quality. Many well-known bird's nest brands in China are from the above origins.

The second is to look at the hair of the bird's nest: the bird's nest picked in different periods also has different "hair".

Third, it depends on whether the bird's nest is clean: the less fine hairs, the better.

The fourth is the pick type: the thinner the head and feet at both ends of the bird's nest, the more beautiful it is.

Fifth, it depends on whether the bird's nest is dry and light: those with dry and less water are the top quality. High-quality bird's nest should feel dry to the touch. Wetter bird's nests contain more moisture and can become moldy if not stored properly.

Six stews: Of course, it refers to the stewed bird's nest, good bird's nest is resistant to stewing, and the bird's nest that is hand-picked is not easy to appear watery, and there will be a strong protein fragrance after stewing, which is an important indicator of true and false bird's nest. Fake bird's nests will not have such a fragrant albumin.

Chemically processed bird's nests tend to turn into watery form if they take too long during the stewing process.

The difference between the high and low of bird's nest lies in six indicators: the degree of trimming of leftovers, the place of origin, the hair, the degree of integrity, the quality of cleanliness, and the taste.
