The introduction of natural bird s nest, what is pure natural bird s nest

Natural bird's nest refers to the nest built by a petrel with saliva. The Compendium of Materia Medica, written by Li Shizhen in the Ming Dynasty, has a more detailed description of bird's nest: When the swallow is about to give birth to an egg, the liquid vomits out, and the silk is knotted into a nest.

For a long time, it flies with the little bird's nest, and the sea people pick it up according to the time, so it is called bird's nest. According to the classification of bird's nest, it can be divided into two categories, namely cave nest and house nest, and both cave nest and house nest are built by the petrel (swiftlet) in Southeast Asia to feed the nest of young swiftlets, generally common swallows on land, most of them are built with hay, wood chips, and bark, and this kind of nest has no edible value.

Cave swiftlet is a type of cave swiftlet that originates from Thailand, Indonesia and Sabah and Sarawak in Malaysia. The Bird's Nest Caves in Sarawak and Sabah are dotted throughout the national parks, forest reserves and coastal islands, Niah, Baram and other places. There are also islands in the South China Sea.

Bird's nest is made by a bird called swiftlet, cemented with moss, seaweed and soft plant weaves mixed with feathers and saliva.

The history of Chinese people's consumption of bird's nest can be traced back to 600 years ago, and here we can tell you a story about bird's nest, according to legend, Zheng He's ocean-going fleet encountered a major storm at sea and was forced to anchor on a desert island in Southeast Asia. There was a severe shortage of food, and the crew stumbled upon a white swallow's nest like a small boat on the cliff, which was picked, washed and stewed in water to satisfy hunger.

When the belt was removed when escaping, the crew was in good spirits and had a powerful voice. When he returned to China, Zheng He brought some to Ming Chengzu. Since then, Chinese have regarded bird's nest as a precious tonic.

Inedible bird's nests: nests built by swifts and sand swallows under the eaves of houses with materials such as soil, grass, branches, and feathers.

FormationRed bird's nest

Red bird's nest is usually called blood bird's nest, most of the swallows in the cave are not called swallows nesting on the rocks, and the minerals on the rock wall seep into the bird's nest, causing the bird's nest to turn from white to red. There is also a possibility that when the swallow is building a nest, due to the consumption of physical strength, the capillaries in the throat wall are ruptured, and the saliva spit out at this time is bloodshot, and it is also partially red after nesting. Unadulterated blood swiftlets on the market are extremely rare, and the minerals contained in blood swiftlets are not necessarily good for the human body, so it is not recommended to eat withered wild blood swiftlets.

Natural bird's nests are formed by the condensation of feathers and saliva.

Bird's nest is formed by a bird called swiftlet that eats moss, seaweed, insects, whitebait, etc., which is digested and then mixed with their feathers and saliva to condense into a solid in the air. This is not only the hiding place of swiftlets, but also the natural form of our edible bird's nest, and then people will pick this bird's nest, after refining, selecting and finally giving it to the majority of potato people.

Blood swiftlets are made of brown-tailed swiftlets. Compared with ordinary swiftlets, the environment in which swiftlets live is different, and the water in their habitat and the walls of the nesting swallow's cave contain high levels of iron, which makes their saliva appear red, and the bird's nest is also blood-colored.

There are three types of bird's nests: bird's nests collected from natural cave nests, house nests raised in captivity and built indoors, and processed bird's nests. In addition, there are artificial bird's nests made from seaweed and fake bird's nests made with starch, etc. This kind of counterfeit can almost be fake, so to identify bird's nest, we must first distinguish the real from the fake, and then divide the category and set the grade.

Features of bird's nest:

Generally, the color of natural bird's nest will be slightly yellowish, and it is normal for bird's nest to be beige gray, milky white, and ivory white. However, if the color of the bird's nest is very white, or even white to the point of shining, and there is no fine fluff on the body, it is likely to be bleached bird's nest. Natural bird's nests smell faintly fishy or Xylella, while fake bird's nests smell pungent chemicals or greasy.

Pure natural bird's nest is generally half-moon shaped or boat-shaped, the body of the bird's nest will have natural gaps left after picking bird's feathers, and the inside of the bird's nest has a rich reticulated sac, the texture is tight and clear. The filament structure of the crushed bird's nest is very irregular.

1. Bird's nest is a nest built by the saliva secreted by several swiftlets of the swift family and their down feathers. It is mainly produced in Southeast Asian countries such as Malaysia, Indonesia, Thailand and Myanmar, as well as the coastal areas of Fujian and Guangdong in China.

2. Bird's nest is rich in sugars, organic acids, free amino acids and characteristic substances - sialic acid, which has the effects of nourishing yin, moisturizing dryness and nourishing qi.

3. The main nutrient in bird's nest is protein, of which there is 1 essential amino acid (lysine) and 3 conditionally essential amino acids, while the human body needs 8 kinds of essential amino acids and 13 kinds of conditionally essential amino acids.

Main origin: Indonesia 80%, Malay 10%, Thailand 5%, Vietnam 2%.

Vietnamese bird's nest: 1. It is sold in China and is extremely rare on the market. Vietnamese people belong to the descendants of Chinese, and in ancient times, they belonged to the country of Nanyue, and they had the habit of eating bird's nest, which is a kind of Chinese health culture. However, Vietnam's production is small, and processing is not good.

Malays and Indonesians don't have such a food culture, so they don't eat it themselves.

Thai Bird's Nest 1, Weizhen production is not high, processing costs are high, and many of the tourist attractions in Thailand are shipped from Indonesia.

Indonesian Bird's Nest Indonesian bird's nest processing and swiftlet houses have a long history, and there is a habit of using medicinal water treatment in the early days, as much as 90%. But it is basically a food-grade potion, which can meet the standard, can be detected, and can be exported, and the purpose of the potion is to make it easy to pick hair and save costs.

3. Indonesia has a large output, goes wholesale, and pays low attention to quality.

4. There are many small family workshops and poor sanitary conditions. Indonesia as a whole is relatively backward, the processing conditions are poor, and the water used is not even tap water. There are also good factories in Indonesia, but most of them are very average.

Malaysian Bird's Nest.

1. The history is short, only 30 years.

2. Strong supervision. The world's first bird's nest chamber in Malaysia. Zeng Yongan was complained about engaging in a swiftlet house in the block, and later negotiated with ** to engage in self-lack mountain inspection management and become a chamber of commerce.

3. Tomato takes the quality route, mostly for enterprises and brands.

4. High level of processing technology and high safety.
