Identify the three types of fake bird's nests: brushing, soaking, and sticking!
One, brush glue bird's nest test methods:
1, soak test: brush glue bird's nest immersed in water to remove, rub with the index finger a few times, such as feeling sticky on the finger, and can smell the smell of chemicals, it belongs to brush glue bird's nest.
2. Break test: If the bird's nest is above 95% dry, break it directly by hand, such as breaking the location of hardness (no crunchy shape), neat break and no more crumbs falling down, then it is brushing glue.
3. Soaking test: If the bird's nests are soaked for more than 5.5 hours, but not yet soaked, and the bird's nests are torn apart by hand, the bird's nests are thick and hard, and the bird's nests are not soft and sticky after being stewed for more than 50 minutes in the same place, then the bird's nests are brushed with glue.
PS: Many people directly judge bird's nest brushing with glue based on photos, just because the surface of bird's nest has a glossy finish, which is totally illogical! Because the surface of bird's nest itself contains bird's nest cream (polysaccharides), which is a manifestation of the overflow of salivary acid from the bird's nest, you can never conclude that the bird's nest is brushed!
Two, soak water (bleach solution) bird's nest test method:
1, smell: bleach solution smell everyone has smelled it ...... If the bird's nest soaked in water, even how to deal with it, the smell will be different from the bird's nest itself with the damp rocky smell, the fishy smell of the birds and birds, more or less. with a little bit of chemical substance odor.
2, color: The color of bird's nest will change due to seasonal changes. There will be: beige, beige-yellow, beige-gray, gray-yellow, golden-yellow, even the top official bird's nest, the color is definitely not snow-white, there will be a little uneven color. If you buy a bird's nest that is snow white, even in color and without any impurities, then 99% of it is soaked bird's nest.
Third, the identification method of broken bird's nest:
1, look at the base: the most common is to stick the broken bird's nest under the base of the bird's nest, usually it is the merchants who stick the broken bird's nest into the base of the bird's nest after soaking. If you see the base is very thick, and there is no texture to speak of, just like a bunch of broken heaps on top. This is the most common type of bird's nest, and it is the most common type of bird's nest!
2. After soaking: After soaking, the base of broken bird's nest will be scattered with the marigold itself. If you hold the soaked base in your hand and use your finger to stick it gently, it will be broken like the broken bird's nest after soaking, then it is a broken bird's nest.
After the triangular marjoram is soaked, the texture of the base is clear and not broken
Summary: Brushing glue and soaking bird's nest will affect the nutritional value of the bird's nest itself, and may lead to health problems after consumption, so if you buy it accidentally, it is not recommended to consume it.～
Sticky bird's nest has little effect on the nutritional value of the bird's nest itself, and there is no problem in consuming it. However, it is not cost-effective to buy broken bird's nests at the same price, because the price difference is more than half a point. The texture of the broken bird's nest is still very different from that of the marigold
