The big bird's nest cups in the picture are all white and flawless, and the stewed bird's nest is clear and transparent without impurities, but many people buy dried bird's nest cups and go home to soak their hair, and find that the bird's nest contains many tiny hairs. Is this bird's nest good or not?

As we all know, the Bird's Nest is a nest built by Jin Siyan with saliva and a few feathers, which is used to breed and feed swallows. Swallows can fly and leave the nest, and then the farmers will pick the bird's nest (Ps: so don't say it's cruel to pick the bird's nest). In the process of nesting life, the bird's nest will inevitably lose a lot of feathers.

When the bird's nest is uprooted, the content of swallow hair is divided into extremely light, light, medium and heavy, and the quality decreases in turn. Heavy swallow can't be used as the raw material of bird's nest, but bird's nest will undergo strict sterilization and disinfection before leaving the factory, and then the hair will be picked manually. A mature wool picker can pick 3-4 bird's nests at most every day, but there will be some tiny hairs in the gaps of bird's nests to avoid destroying the integrity of dried bird's nests, but not many will be preserved.

Manual hair picking needs to be done one by one, and the integrity of the swallow cup cannot be destroyed. Therefore, it is normal to dry the bird's nest and plant fine hair. Even many people buy bird's nest with fluff, which proves that the bird's nest has not been chemically bleached, and the bird's nest after chemical bleaching is white, and the swallow hair has been burnt by chemical reagents.

So don't worry about the bird's nest with tiny fluff bought by friends, just pick it with tweezers after soaking. However, it is best not to buy Yan Yan, especially Mao Yan, although the price in Mao Yan is very cheap.

Mao Yan is an untreated raw material for bird's nest wholesale. Because there are no procedures such as disinfection, sterilization and manual hair picking, the cost is very low, so the price is very cheap compared with net beauty. However, the bird's nest is where swallows live. Swallows always eat and drink Lazar on it, and the cleanliness is worrying, which is not conducive to long-term preservation and is easy to breed bacteria. Therefore, the health and safety of Mao Yan without disinfection and sterilization cannot be guaranteed, and it cannot be eaten regularly.

At present, the bird's nest sold by regular manufacturers is a bird's nest cup with clean surface. After strict sterilization and manual picking, it has passed the national inspection and quarantine, so the safety is guaranteed. If it is normal to have fine fluff after soaking, you can also pick it out or eat it directly twice at a time.
