What is the fake bird's nest like?

Bird's Nest has only emerged in China in recent years. Many people have eaten bird's nest in hotels, but they don't particularly know what the real bird's nest is like. Now teach you some ways to tell the true and false bird's nest.

The key points of choosing bird's nest are "one look, two touches and three dips":

Look: mainly depends on whether the bird's nest is clean, with less impurities and tight fibers;

Touch: mainly to measure the dry humidity of bird's nest;

Soaking: If the bird's nest is completely inelastic or oily on the water after soaking, it is a fake bird's nest.

Because bird's nest is expensive, there are many fake and shoddy products mixed in the market. Common fake materials are: fish glue, pigskin, tremella, shark fin and so on.

The identification of true and false bird's nest depends on seeing, smelling and pulling.

Look: bird's nest should be a filamentous structure, and the flaky structure is not a real bird's nest;

Smell: those with special smell, fishy smell or greasy smell are fakes;

Lara: Take a small piece of bird's nest and soak it in water. When it is soft, pull it with silk strips, which has poor elasticity.
