Look at the body

Before you buy a bird's nest, you should search for a comparison chart of the sparse and dense jian, like the kind of jian body has no gaps, dense and impermeable, this kind of direct pass, either brushing glue or pushing the dense, like the kind of gap is very big, the bird's wire is very thick basically are sparse jian, do not recommend to buy, all are used in the heavy hair of the bird's wet picking, not much nutrition. The normal gap of the kind, and in the sunlight can see the natural gap, this is the dense marigold, buy this kind.

Look at the base

Like that base is very heavy, a bubble hair all is broken, basically make up for the broken, this kind if not very cheap do not buy. Like the base is relatively light and thin, even a little wider does not matter, this will not step on the mine.

Look at whether it is fully dry

Fully dry bird's nest is gently pinched on the broken, sometimes transport received a little cracked that are basically fully dry bird's nest, it does not matter, does not affect the quality of the, but like how to pinch the pinch can not be crushed, touch is still wet water bird's nest, do not buy, not only is prone to mildew, the focus is mixed with water, for the water to pay the bill.

Look at the soaking time

General natural bird's nest soaking 4 hours is almost the same, the Yan corner of the part of the more difficult to soak, usually 5 hours or so, like the kind of marigold body parts soaked for five or six hours has not been soaked, basically, is to brush the glue, this can be directly to find the seller of the after-sales service.

Look at the soaking water

The natural bird's nest soaking water is clear, but there will be a little bit of small fluff, like brushing glue/medicated bird's nest soaking water is cloudy.

Smell it

Natural bird's nests are basically a bit musty, and the smell will actually be bigger after you spray it with water. After stewing, the bird's nests are egg-white in flavor, and it's not quite right to smell fishy and fishy like that. And the pungent odor of that potion is not right.

Look at the traceability code

This point is really important, now the traceability code is really false, we just need to remember one thing, China Inspection and Quarantine Scientific Research Institute, Web site ebn.caiq.org.cn only the only one Web site is our national test, the other are false traceability code!
