How to tell whether bird’s nest is authentic? Look, touch, soak, smell

Bird's nests are expensive, and many vendors sell inferior products as good ones or use cheap foods such as pork skin to imitate bird's nests, or use glue to piece together bird's nest fragments to pass them off as high-quality bird's nests.

First of all, a good bird's nest is 100% dry. Bird's nest mixed with water not only causes economic losses, but also high-protein bird's nest is easy to breed bacteria when it comes into contact with water. Such bird's nest is harmful to the human body. When you buy bird's nest, you can pinch the bird's nest with your hands to test it. The one that breaks easily is a good bird's nest.

Bleached bird's nests are mostly dyed with inferior pigments, which not only destroys the nutrients but also contains chemical residues. Instead of buying health, it harms the body. The color of high-quality bird's nest is slightly yellow or natural beige.

A good bird's nest depends on the quality. Good bird's nests are generally processed with light hair nests, with clear bird's nest fibers, natural texture and beautiful nest shape.

Bird's nest should be in a filamentous structure. If it is made up of sheets or blocks, it may be spliced ​​together. These are all things to pay attention to when purchasing.

The smell is also a very important clue. Good bird's nests have a light and fragrant egg white smell. Some old bird's nests have a light musty smell, which is also very normal. Poor quality bird's nests will have a fishy and greasy smell.
