How to judge the dryness and wetness of bird's nest.

Friends who often buy bird’s nest should know that bird’s nest is sold in grams, so when buying dried bird’s nest, the higher the dryness of bird’s nest, the more affordable the price. If the water content of bird’s nest is high, even if the price is cheaper for one gram 2, 3 yuan, the overall consumer is still expensive. Dryness means that when the actual weight of the bird’s nest is the same, the lower the moisture content of the bird’s nest, the better. What is the criterion for determining the dryness? How to judge the dryness of bird's nest?

1. There is no strict criterion for the dryness of bird's nest

The geographical environment and climate are different in different regions of the world, and the rainfall and humidity in the air are also different. As a result, the bird’s nest absorbs the moisture in the air and increases the bird’s nest during the transportation to the humid city or during the sale process. The moisture content of the bird's nest increases its weight; on the contrary, when the dry bird's nest is transported to a city with lighter humidity or dry, the moisture of the bird's nest will be evaporated and the dryness will increase and the weight will be reduced. Therefore, the dryness of bird's nests does not have strict standards around the world, and it depends on the actual situation.

This kind of increase in the weight of bird's nest due to geographical weather is limited, and will not have much impact on the quality of the bird's nest itself. What we need to be wary of is the artificially increased weight.

2. The bird's nest is absolutely 100% dry

Absolutely 100% dry, that is, the bird's nest is absolutely moisture-free, 100% dried bird's nest. This is difficult to achieve. The texture of bird's nest itself is very brittle. If the bird's nest has no moisture at all, it will break when touched and cannot be transported. In addition, retailers and wholesalers sometimes try to reduce the damage of dried bird's nest during transportation. The cost of the consumption will also be sprayed on the bird's nest. Therefore, what the merchants say is dry, not 100% dry, it still has a certain water content.

3. How to judge the dryness of bird's nest

Dry bird's nest depends on touching and smelling: Under normal circumstances, the dryness of retail bird's nests should reach about 98%, and the minimum should be 95%. This kind of dry bird's nest will feel dry and dry when touched by hand, and the corners and base of the bird's nest will feel harder and more brittle. The smell is relatively light and not very strong.

Soaked bird's nest looks elastic: high-quality dry bird's nest has low moisture content and high dryness. After soaking, the silk strands are clearly visible and elastic. If the bird’s nest is soaked, pick out a bird’s nest, which has poor elasticity, and it breaks when you pull it. It is a fake if you rub it with your fingers. If there is no elasticity to make a paste, it is also a fake. It may be artificially sprayed to increase the weight.

Stewed bird's nest depends on taste: there is a slight egg white taste, and the water content is low. If the egg white taste is very strong, it is fishy, then the water content in the bird's nest is high, so the dryness of the bird's nest depends on the richness of the egg white flavor. , The stronger the moisture content, the higher the moisture content. If you buy bird’s nest with more moisture content, you can dry the bird’s nest in a cool and dry place before eating
