The type of bird's nest and the characteristics of bird's nest

Every time we go to visit the bird's nest shop and look at the glistening bird's nest on the counter, many people, like the editors, are confused. I don't know that there are so many kinds of bird's nests. How is the type of bird's nest? What kind of species are there?

First, according to the nest environment can be classified:

1. Dongyan: It is a bird's nest built on cliffs and cave walls by the swiftlet. It is gradually replaced by House Yan because of the scarcity of production volume and increasing environmental protection.

2. House Yan: It is a bird's nest nestled in artificially-built houses. The swiftlets are still wild. They go out for food in the morning and return in the evening.

3, grass Yan: Some swiftlet nest to do in the grass from the bird's nest mixed impurities.

Second, according to the swiftlet species and nesting habits classification:

Blood Yan

The nest is red or light red. Most of them are nests built by brown-tailed swiftlets. Because the brown swiftlet has a higher level of copper oxide in its living environment, the predatory insect has a higher content of iron (iron food), so the saliva it secretes is light red, commonly known as blood swallows. In addition, nests built by other types of swiftlets may also change their nest color to blood red due to food or the external environment. Blood Yan dip stew for a long time, taste refreshing, fragrant fire-resistant. Due to low output and high demand, its price is higher than other types of bird's nest.

Bai Yanqi

In all kinds of bird's nests, Baiyan is the most tender and not fireproof. Especially house swallows. This is because within the bird house, bird's nest has the shortest picking time (on average every three months). In addition, due to the different types of nesting swiftlets, the structure of house swallows and cave swallows is different. The white house nest's silk is thin and lubricated, while the white one is slightly rough. Therefore, it indirectly affects the dipping time and the heat of the bird's nest. The texture of the Baiyan in the cave is relatively firm and the expansion force is also large. After the top of the product has been stewed, it not only smells fragrant, but also tastes fresh, lubricious and refreshed.

Mao Yan

Mao Yan is a type of Dongyan. Its origin includes Thailand, Sabah, Malaysia, and Sarawak. The Sarawak and Sabah bird's nest caves are found in national parks, forest reserves and coastal islands, Niah and Baram. Mao Yan is mainly a nest constructed by grey-haired swiftlets. This kind of swiftlet nature likes to build nests with saliva and their own hair (on average, a nest contains about ten to fifty percent of the feathers). Other species of swiftlets, nests built for the second time or the third time, may be classified as Maoyan if there is insufficient saliva and if there are many feather impurities. The thickness of Maoyan's nest varies from place of origin, but the nest color is generally darker, with more impurities, especially villi, so the processing process of Maoyan is rather complicated.

Cao Yan

Grass swallow is a wild swallow, and it has strong ability to adapt to various environments. They used to pick grass and spit out their own saliva to nest. When the grass nests and the saliva condenses into the nest, it becomes a shelter for the next generation. Therefore, the bird's nest built by this type of swiftlet is covered with grass pieces. Therefore, it is easier to distinguish the grass bird nest from other kinds of bird nest. Basically, “there is grass”. This swallow is abundant in the Sulu Sea in the southern part of the Philippines and is also known as the Philippine grass bird. Grass Yan's processing is simpler than Mao Yan. In the processing plant, the workers need to separate the grass and debris and saliva before further processing. After that, they are organized into various shapes according to the needs of the market. The smell of Caoyan was inferior to that of House Yan and Mao Yan.

Third, according to the shape to be divided into Yan, Yan, Yan broken, Yan cake, Yan Jiao, Yan net and so on.

1, Yan Yi: There is a complete shape of the bird's nest

2, strips: crushed during picking or transport, relatively large

3. Yanjiao: The two sides of the bird's nest are fixed at the time of construction, and it is also the top beam column of the entire bird's nest.

4, Yan Si: pick hair process brought down, was filamentous

5, broken pieces: transport, hair picking, crushed packaging process, broken shape

6, Yanqiu, Yan cakes: from the swallow broken (Yan Si) through the mold processing

7, Yan network: bird's nest in the middle to support the egg and Xiaoyan's slender network, delicate and smooth taste.
