How to judge the quality of bird's nest

Many people like to eat bird's nests, but few know how to distinguish the quality of bird's nests. Among the items, blood bird's nest is the rarest, and now it has even become a very professional term, which only appears in books and is almost extinct in the market. There are some so-called merchants selling blood bird's nests. If consumers have no idea about blood bird's nests, they must be more careful. Here we will introduce how to distinguish the quality of bird’s nest.

The cave swallows appear a partially irregular rust-red color due to the infiltration of minerals from the rock wall, but they are not blood red all over, and mostly the rust color appears on the edges and corners. The color of real cave bird's nest is uneven, and the bird's corners and the lower part of the bird's nest are much darker. Many people in the market say that fake cave bird's nest turns red after being soaked in water. This statement is actually not very accurate.

Some counterfeiters are very sophisticated and can paint a non-fading red color on fake bird's nests. The real cave bird's nest will appear light red in water after being soaked. This is caused by the unique nutritional structure of the blood bird's nest. Therefore, you cannot use the color of the soaking water to distinguish the authenticity of the cave bird's nest. The identification of cave bird's nest mainly depends on the color distribution. If it is blood red or dark red all over, it is mostly fake cave bird's nest, and it will not turn into water when stewed normally.

Look at the certification documents for imported bird's nests. The quality will be guaranteed only if there is an inspection certificate and a health certificate issued by the China Inspection and Quarantine Bureau. Look at the color and shape of the bird's nest. A good white bird's nest is ivory white in color. A particularly white one is likely to have been bleached. As for the shape of the nest, an irregular half-moon shape, a depression in the middle to form a pocket shape, a hard and brittle texture, translucent, and a mirror-like luster on the cross section, with a slightly horny feel, is considered a good shape. And a good bird's nest bowl has gaps, because in the process of artificially picking the feathers of the bird's nest, some gaps will be formed. These gaps are originally the fine hairs of the swallows or some other impurities, so it is normal to have gaps.

When identifying bird's nests, you also need to smell it. If it is a normal bird's nest, it will smell like a faint smell of egg white. When the bird's nest is cooked, this faint smell of egg white will become more intense. If the bird's nest smells chemical, fishy, ​​or sour, then it is either fake or counterfeit.
