The price of authentic bird's nests in the market is getting higher and higher. Many merchants are passing off fake ones as genuine, making it difficult for consumers to distinguish good from bad ones. Now, let me teach you how to judge the quality of bird's nests. Hurry up. Come and learn.
1. Look at the appearance.
When purchasing bird's nests, you must first look at the overall appearance of the bird's nest, including its external packaging. For imported bird's nests, you need to see whether there are relevant import certification documents, as well as certificates and health certificates. Wait, then look at the color of the bird's nest. Generally, the color of good bird's nest is ivory white, and the white and shiny ones are mostly bleached. Next, look at the shape of the bird's nest. Good quality bird's nests have gaps in between and are half-moon shaped. It is translucent, with a depression in the middle and corners.
2. Touch.
To identify the quality of a bird's nest, you can also touch it with your hands. If it feels hard and crisp, it is a good bird's nest. If it feels dusty or soft, it means there is more water and impurities in the bird's nest, and the quality is poor. Poor.
3. Smell.
A simple criterion for judging the quality of bird's nests is to smell the bird's nest through your nose. Pure bird's nest will emit a unique and light fragrance, while isinglass, starch, seaweed, eggs, etc. are added to the bird's nest. Inferior bird's nests will have a greasy, fishy, ??and chemical smell.
4. Soak in water.
In addition, if conditions permit, you can also identify the quality of bird's nests by soaking them in water. After being soaked in water, good bird's nests have a certain degree of elasticity and are not easily torn. They are in the shape of silk strips, with different lengths and thicknesses. They are all different. They will not feel sticky to the touch, and their natural color will not change. On the contrary, if the bird's nest changes color after being soaked in water, feels sticky, and has poor elasticity, it is a poor quality bird's nest or a fake bird's nest.
