Is the instant bird's nest brought back from Thailand really good? It was brought back by the tour guide.

How to judge the quality of bird's nest;

Look at viscosity. You can usually see the truth by shaking the bottle. If it is a real bird's nest, it can shake with the shaking of the bottle. The bird's nest itself will not sink to the bottom of the bottle, nor will it float above the bottle, but will be hung in the bottle. Fake bird's nest is usually filled with tremella, and the liquid is thick and not easy to shake.

Look at the ready-to-eat bird's nest with good shape. It is made of bird's nest cups and strips, which are in the shape of silk strips with different lengths and thicknesses. If the shape is flocculent, it is made of Yan cake, broken Yan and so on. The quality is slightly inferior and it is easier to make fakes. The fake bird's nest posing as tremella is flaky.

Look at the color. Instant bird's nest juice is light white, light yellow or light brown, crystal clear. If the soup is turbid, it is likely that stabilizers or thickeners have been added, or fine swallowing scraps have been used.

Smell it. Although bird's nest has a faint protein smell, it is by no means a strong fishy smell, and it will not have a greasy taste. If it smells strange, it is probably made of pigskin and fish bones.

Look at the elasticity. Gently pull the instant bird's nest. If it is easy to break, it means it is fake. Because other ingredients added may dissolve out, this is most likely to happen in the bird's nest processed by tremella.

High-quality bird's nest tastes delicate and smooth, sweet and delicious. If it tastes sticky, it is probably added with glue or thickener.
