The classification standard of bird's nests

Bird's nests are generally classified according to the "dense, thin, sparse" and cup shape of the bird's nest. Those that are denser and have a well-proportioned cup shape are classified as top-grade. Yanzhan, the sparse ones are inferior. Bird's nest products can be divided into the following types according to their appearance and processing methods:

1. Bird's nests: workers select nest-shaped or boat-shaped bird's nests from the harvested bird's nests, and then sell them after small plucking. Yanzhan is taken out naturally, so its shape and size are different. Its nutrition, fragrance and hair are the best. The cleanest product out there and the best hair.

If the swallow builds its nest on the beam of the swallow house, the swallow cup will be in the shape of a boat; if the swallow builds the nest in the corner, the swallow cup will be in the shape of a triangle.

2. Bird's nest strips: strip-shaped bird's nests that are broken when harvesting bird's nests or cut from bird's nests. The hair is basically the same as the bird's nest.

3. Bird's nests/bird's balls: Bird's nests crushed by workers during harvesting, pressed into different shapes (such as rhombus, spherical, half-moon, rectangular, etc.). Usually taken from grass swallows and feathers The quality is poor, not recommended to buy.

4. Yanjiao: Yanjiao does not refer to large pieces of swallow. This is a serious mistake! Yanjiao refers to the harder ends of the swallow. This part is also the place where the swallow's saliva is thickest and requires a longer soaking time (8 to 12 hours). The swallow's horns are usually cut out and soaked in water separately, and the swallow's horns are torn into pieces before soaking. It makes it easier to soak the hair. The hair is larger than that of Yanzhan, and it is more refreshing.

5. The price of Yanzhan is very thin. < /p>

6. Broken: It is seriously broken during transportation or harvesting. It often contains impurities or is a mixture of several qualities.
