How much do you know about bird s nest?

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.

Bird's nest is a nest built by swallows.

Of course, the swallow referred to here is not an ordinary house swallow, but an oak swiftlet, whose saliva has a very high protein content, and the ancients even compared it to ginseng and deer antler velvet. When it comes to bird's nest, there has always been a big controversy in terms of both the best and the nutritional value.

In terms of nutrition, bird's nest contains a variety of nutrients needed by the human body, such as protein, minerals, and carbohydrates, etc., although its effect is not as miraculous as imagined, but reasonable intake also has many benefits for the body.

Buying secrets

First, the origin should be fixed: the place where swiftlet grows affects the quality of bird's nest production, the production area is industrially developed, the more impurities such as dust, the darker the bird's nest produced by serious air pollution, the higher the rainwater and forest coverage area of the production area, the better the bird's nest produced 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.
