Since the Ming Dynasty, bird's nest has been cherished by people because of its natural characteristics, which has the effect of medical care and is regarded as a nourishing sacred product. There are many bird's nests in the market now. For bird's nest fans, the biggest worry is that they spend money but buy fakes. In order to prevent bird's nest lovers from buying fakes, today I will introduce you to the method of distinguishing true and false bird's nest.
First of all, color
Whether saturated or in light, pure bird's nest is not completely transparent, but translucent. The color of real bird's nest is natural gray-white, white, uneven, with some chromatic aberration. If it is bleached bird's nest, the whole bird's nest will look very consistent and white.
Second, the taste.
If the humidity of bird's nest is high, the taste of eggs will be stronger. Some dried bird's nest smells very weak. The smell of bird's nest is more obvious. The thicker the egg white, the better the bird's nest. The taste is also smooth.
If it is bleached bird's nest or brushed bird's nest, there is basically no egg white smell, and bleached bird's nest even has a strong chemical syrup smell, which is dry and inelastic.
Third, texture.
The texture of real bird's nest is different in thickness. The texture is clear, natural and delicate, and the cup body has slight horizontal stripes and irregular seams. Look carefully, the thickness of the swallow strips is uneven. The texture of real bird's nest will not feel very smooth, but it will feel concave and convex.
The adulterated bird's nest looks unnatural. The thickness of the strips is very close, and there is basically no gap in the middle of the lamp. Glued bird's nest also looks like a thick layer of skin on the surface of bird's nest.
Fourth, hair.
It is normal for bird's nest to have a hair multiple of 5-8 times or even 10 times. Only the special fake bird's nest can be less than 5 times. Of course, the higher the quality of bird's nest, the better the effect. After the bird's nest is soaked in water, the thread is broken and the elasticity is poor. If it is damaged, it is a fake. If you rub it with your fingers, it is not elastic and it is also a fake.
V. Cup shape
The complete true bird's nest is irregular and half-moon, with relatively neat edges, rough interior and nested depressions. There are patterns of loofah road at the bottom and both sides, which are relatively uniform, convex, with slight horizontal stripes and often cracks in the middle. Adulterated bird's nest will thicken in swallow cups and horns.
Increase the weight of bird's nest. The cracks in the middle of the thickened swallow cup are filled, and the bottom and sides are still loofah-shaped, but the thickness is uneven, irregular and without horizontal stripes.
Six, burning
When the real bird's nest burns, it will have slight cracks, bubbles and a slight smoke smell. It tastes like burning hair, carbonized and gray. The burning of fake bird's nest will make a violent sound, and Mars will splash bubbles, which will not bubble and produce more smoke.
Seven. traceability
At present, the four largest bird's nests in the world are Malaysia, Indonesia, Thailand and Vietnam. , the traceability information will be scanned when purchasing. The difference between real bird's nest and fake bird's nest needs careful consideration. It is difficult for you to distinguish real bird's nest from fake bird's nest in the theoretical stage.
Be sure to integrate theory with practice, see more objects, compare more objects and observe more purposefully, and you will become an expert on bird's nest!
