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 made of mucus secreted from the throat of swiftlets. The swiftlet's head has a well-developed mucus line, and these mucus secretes it can solidify into a solid form in the air, and the swiftlet builds its own nest through this property, and after forming it, it takes on a half-moon or triangular appearance, which looks like an irregular network of filaments. <

Bird's nest is a bird's nest called a swiftlet, which is made by cementing their feathers and saliva using moss, seaweed and soft plant weaves.

Bird's nest refers to the saliva secreted by some swifts of the swift family and several swiftlets of the genus Swiftlet, mixed with other substances. Also known as bird's nest vegetables, bird's nest roots, bird's nest can be divided into "house nest" and "cave swallow" according to the place of nesting, cave nest because of its mineral influence causes different colors, there are white bird's nest, yellow bird's nest, red bird's nest, and house nest only ivory white a color. 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".

Main production areas

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. Among them, Indonesia has the best quality of bird's nest due to the weather and environment that is most suitable for swallows to live, and Indonesia's bird's nest production is also the largest, followed by Malaysia.

According to statistics, as of the end of 2010, Indonesian bird's nest accounted for 85%-90% of the world's bird's nest production, Malaysia accounted for 5%-10%, Thailand 3%, Vietnam, the Philippines and other places about 2% (refer to the data of the Hong Kong ** Department for several years). A subspecies of Javanese swiftlet, cfuciphagagem ani, has been found on the island of Yannan Dazhou to produce edible bird's nests.

Swiftlets are produced in southwestern China and southeastern Xizang, and the earliest well-documented works are "Materia Medica" and "Benjing Fengyuan". There are six species of swiftlets that produce bird's nests because the saliva secreted by various birds of the genus Collocalia in the family Apodidae is mixed with their down and condensed on cliffs or farmhouses.

The swallow's salivary glands secrete a gelatinous saliva that acts like glue to hold down feathers and other substances in place, and eventually shape a nest.

The bird's nest made in this way will become translucent under the action of gum after molding, which has strong toughness and is very comfortable to live in.

In the ordinary sense, the most important component of saliva is water, and other substances such as enzymes and sialic acid are relatively few. However, in the saliva used by swallows to make bird's nest, the main components are sialic acid and protein-like substances, and water is secondary.

In particular, sialic acid is a special substance composed of sugars, organic acids, free amino acids, and characteristic substances in terms of composition.
