How to tell the quality of freshly soaked bird s nest?

At first glance, the color is clear, clean, and thick (the flashlight is lit at the bottom of the bottle, so you can see it more clearly) The second smell, the protein fragrance (keep a distance of 10 cm between the mouth and nose and the bottle mouth) Three products, Q bomb is smooth, and the mouth is full (directly into the mouth). If you've ever eaten Bird's Nest's freshly soaked bird's nest, you'll know what pure bird's nest is.

1. First look at whether the bird's nest is dry and light, and the bird's nest has a dry feeling when you touch it, which means that the bird's nest does not contain excess water, and the shape of the premium bird's nest is large and thick, (about three or four fingers are stacked together).

2. Pure bird's nest should be a filamentous structure, the bird's nest is fine and dense, whether it is soaked or under the light** is translucent.

If the bird's nest is made up of pieces of structure, it is not a real bird's nest, and it is not genuine if it is completely transparent after soaking.

3. Smell, bird's nest has a unique eggy smell. If the smell is special, the fishy smell or greasy smell is fake, and the strong smell or musty smell is defective, (it has been processed).

4. After soaking in water, the water of pure bird's nest is clear. If the water is cloudy, it means that the bird's nest has been processed (with bird's nest powder to add weight). If you rub it with your fingers, it is also a fake if it has no elasticity and can be kneaded into a paste.

Looking at the degree of expansion of bird's nest: different types of bird's nest also have different degrees of expansion (i.e. the difference between the weight of bird's nest after it is soaked and when it is dried, the greater the multiple, the better the degree of swelling), and the degree of swelling of high-quality bird's nest is 6 8 times.

The soaked whole bird's nest weighs about 6 7 times the original weight after draining, and feels soft and elastic.

Bird's nest is also a kind of food, and there are also grades. Good bird's nests are relatively large in size, and the soaking time needs to be longer; The soaking time of the bird's nest is shorter, and the filaments are not thick.

In order to make the bird's nest have a better hair, the water used for soaking must have good permeability and cleanliness, and the ideal choice is drinking water or cool and white, which is conducive to full soaking.

Bird's nest should be picked up first, and then soaked in water, and when the bird's nest is completely soaked, the color becomes transparent, and the hand is soft and soft, that is, it is good to soak, and then wash it, stew it in a saucepan, or put it in a pot to stew, and then put rock sugar to eat it.

See if it is soft and swollen.

Depending on the variety, the soaking time of the bird's nest is different:

Blood Bird's Nest: Soak for 6-12 hours and simmer for 1-2 hours.

White Swallow: Soak for 4-6 hours and simmer for about 30 minutes-1 hour.

Swallows: Soak for 1 hour and simmer for 30 minutes.

Many people like it when they see that the larger the shape, the whiter the color, and the more perfect the shape when choosing bird's nests in the market, the more they like it, which of course does not rule out that you have bought a top-level official bird's nest, but it is also very likely that you will buy a "beautiful" bird's nest after artificial treatment. Therefore, when buying bird's nest, you must not blindly pursue the beauty of bird's nest. So how can you tell if bird's nest is good or bad?

How to tell the difference between good and bad bird's nest?

1.Dryness. High-quality bird's nest should have a high dryness, and it will break if it is slightly broken. The higher the dryness, the easier it is to store, and it will not become moldy when stored in a cool place. The poorer bird's nest is not up to standard in dryness, and it is not easy to break it by bending it by hand, so the bird's nest has high humidity, accounts for a large amount, and is not easy to store.

Generally, ninety percent dry is the best, ensuring quality and easy transportation.

2.Natural crevices.

After washing the bird's nest, many bird's nests will produce gaps and cannot be restored to smoothness, this is because the bird's nest has the down feathers of swiftlets, which need to be picked, and there will definitely be gaps after manual picking. For the sake of the beauty and weight gain of bird's nest, some unscrupulous merchants will brush glue on the bird's nest to repair the gaps. Therefore, brushing glue bird's nest will look airtight and tight.

High-quality bird's nest can see natural and clear cysts and textures under sunlight and light.

3.Cleanliness.

Bird's nests generally contain bird's feathers and a small amount of impurities, the less these are the better, indicating the higher the cleanliness. There are generally three kinds of picking techniques for bird's nest: dry picking, semi-dry picking and wet picking, generally the best raw materials can choose pure dry picking, followed by semi-dry picking, and wet picking is the heaviest hair.

4.Palate. After the good bird's nest is stewed, it will have the fragrance of egg whites, the taste is smooth and smooth, and if it is a bird's nest, the fragrance will be even stronger. Inferior bird's nest is generally treated with chemical potions or glue, and after stewing, there is no fragrance, and the taste is not good, and some even feel the taste of glue and the taste of chemical system, which makes people tasteless when they smell it.

Therefore, I would like to remind all readers to keep their eyes open and discern carefully. Reasonable and balanced intake, maintain good health, eat vitality, eat healthy!

Origin: Indonesian bird's nest accounts for 80% of the world's total bird's nest production, Malaysia 13%, Thailand 5%, Vietnam 2%, China has three places of bird's nest: Yanyan in Huaiji County, Zhaoqing City, Guangdong, Yanzidong in Jianshui County, Honghe Prefecture, Yunnan, and Dazhou Island in Hainan (the island has been closed for protection).

With the growing call for the protection of nature, the Chinese in Indonesia invented the swiftlet house came into being. The structure of these swiftlet houses is no different from ordinary houses, but the swallows are not birds, the swallows are still wild and foraging for food on their own, and the houses are only used to attract swallows to live in the house, so that the swallows can build small nests in the bird's nests, and there is a large amount of bird's nests to collect. The bird's nests in the environmentally conscious swiftlet house will not be picked until they hatch in 18-24 days and fly in 45 days.

The swiftlets return to the house to build a new nest, which has been passed down from generation to generation. The eco-friendly house nest is cleaner and smoother than the cave nest in the harsh environment, white and delicate. Most of the world's best bird's nests come from Malaysia and Indonesia.
