What is the difference between an official swallow and a blood swallow, and what is the difference b

Guan Bird's Nest is a variety of bird's nest, which refers to the white bird's nest (white bird's nest) with better quality and complete shape. It is said that in ancient times, when paying tribute to the nobles, they would select clean and complete high-quality white bird's nests. This is where the name of Guanyan comes from.

Blood swallow", many people mistakenly think that because the swallow nests lack saliva, even the blood is spit out to build the nest, so it becomes the blood swallow Yunyun. In fact, the blood swiftlet is a kind of "brown-tailed swiftlet", and the formation of the blood swiftlet is affected by the growth environment and water quality and gradually oxidizes to form a red color. Because of the small output and the scarcity of things, it has only been promoted in recent years.

In ancient times, official swallows were more expensive than blood swallows. Compared with the two, white bird's nest is rich in collagen, which is beneficial to women's health and beauty. It is easier to absorb, has a good taste, and is more convenient to make and stew.

Blood bird's nest is rich in minerals, with slightly higher content of sodium, magnesium, copper, phosphorus, potassium, etc. The point is that many of the ones on the market are artificially colored, so don't buy them easily if you don't have enough ability to identify them.

The blood bird's nest is the best in maroon and unbroken, and it is the richest in nutrients such as iron and minerals. Blood swiftlets are caused by the species of swiftlets, the gathering places in different places, the substances contained in the organisms they swallow and the influence of water quality, resulting in the reddish color of the saliva secreted by the swiftlet, and the weathering. The longer these blood bird's nests are stored, the darker their maroon becomes.

The nutritional and therapeutic effects of blood bird's nest are better, and doctors regard them as treasures, but because the production of blood bird's nest is small, the price is higher than that of official bird's nest.

Key points of authenticity identification of bird's nest: Because of the high value of bird's nest, there are many counterfeit and adulterated products mixed in the market, and common counterfeit materials are: agar, fish gelatin, pig skin, white fungus, etc.

Distinguish between real and fake bird's nests: one look, two smells, and three pulls. A look:

Bird's nest should have a filamentous structure, and it is not a bird's nest that is composed of a lumpy structure; Second smell: the smell is special, and those with fishy or greasy smell are fakes; Three pulls: take a small piece of bird's nest to soak in water, take the silk strip and pull it after it is soft, the elasticity is poor, and it will break as a fake, rub it with your fingers, and there is no elasticity to rub it into a paste is a fake!

From the color of the characteristics: the commercial bird's nest is divided into red bird's nest (blood bird's nest), dragon tooth bird's nest, white bird's nest, and yellow bird's nest, among which yellow bird's nest is relatively rare, and it is the best product in bird's nest. White bird's nest color is white, red bird's nest is better than dark red, red bird's nest is more expensive than white bird's nest.

When purchasing, it is better to use the whole bird's nest shape.

The differences between blood swiftlets and snow swifts are as follows:

Snow swallow is the pith secretion of the plant of the apple tree of the genus Apple Po, which is called "snow swallow" because it is more similar to bird's nest after soaking. Swiftlets are mainly found in Myanmar, China, and Yunnan, with a small distribution in Vietnam.

Blood bird's nest refers to the nest of swiftlets cast in the cave, because the bird's nest itself contains minerals, and at the same time is oxidized by the hot air, so that the color changes and becomes orange-red or gray-red, because it absorbs a variety of minerals in the cave, so it contains trace elements are particularly rich.

Snow swallow is the plant pith secretion of the apple tree of the genus Ping Po, because it is more similar to bird's nest after soaking, it is called "snow swallow", mainly grows in Myanmar and Yunnan region of China, and has a small distribution in Vietnam.

The swift is made by manually cutting the trunk of the tree, punching holes to collect the pith secretion, and drying it. It inhibits sucrose absorption and reduces blood sugar elevations.

Swiflets nest, a type of cave swallow.

It is the swiftlet that nests on the rock wall of the cave, and the minerals inside the rock wall slowly penetrate into the bird's nest through the contact surface between the bird's nest and the rock wall or through the dripping water of the rock wall.

The differences between official bird's nest and bird's nest are as follows:

First, the design features are different

1. Bird's nest: Bird's nest digests and absorbs minerals of different compositions, and the color is orange-yellow.

2. Official swallow: generally milky white or gray-white, the bird's nest has been stored for a long time, and its hue will gradually transform from pearl milky white to gray-white.

Second, the composition of high-quality protein is different

The main reason is that the high-quality protein of bird's nest in a certain area is higher, so the calcium content of bird's nest is also higher, and the air oxidizes and turns yellowish, so the high-quality protein of bird's nest is higher than that of official bird's nest.

Proper soaking methods and steps for bird's nest

1. Put the dried bird's nest into a container of purified water, as much water as possible, because the bird's nest will swell during the soaking process.

2. Soak for two hours to change the water, and by the way, tear the bird's nest into strips along the texture, the bird's nest is the load-bearing part of the bird's nest, so when the swiftlet is spitting out, the saliva concentration is larger, and the time required is longer.

3. After tearing into strips, you can wash off some fine hairs and impurities with water several times, and then replace it with clean pure water and soak it for 1 and a half to 2 and a half hours.

4. Take out the soaked bird's nest, squeeze the water of the bird's nest with both hands and put it in a clean dish or stew pot, most of the tutorials are taught to drain the water with a colander, I don't like it very much, because it is almost impossible to drain the water with a colander until it is no longer squeezed, it will take a long time, it is more convenient and fast to squeeze directly with both hands, and you can wear disposable gloves so that it is more hygienic.

Since swiftlets secrete saliva before each spawning and nesting is a cyclical physiological response, there is no difference in the quality of bird's nests harvested three times a year. Blood-inducing swiftlets are mostly produced in Thailand's Roland Rock Mountain, Kangshi Mountain, Songkhla Mountain and other places, but it is not formed by the blood vomited by swallows as legend has been said.

What is Blood Bird's Nest

Blood bird's nest is actually a kind of bird's nest, it is a fine bird's nest, it is the swiftlet nesting on the rock wall of the cave, the minerals in the rock wall react, so that this bird's nest absorbs a large amount of trace element iron, so that its color changes, become the red bird's nest that people see, people also name it blood bird's nest according to its characteristics.

Blood bird's nest is the nest of swiftlets, which is a type of bird's nest, and the reason why blood bird's nest is red is because the minerals in the bird's nest have changed color due to long-term oxidation.

Bird's nest is a valuable nourishing and nutritious product, but among the bird's nests sold by many merchants, there is a kind of bird's nest called blood bird's nest, what is blood bird's nest? Let's find out.

01 Swiftlets feed on seaside algae, mountain insects, flying ants, etc., which are rich in minerals, so their saliva also contains more minerals.

02 The minerals contained in the rock wall where swiftlets nest nest will penetrate into the bird's nest through the contact surface between the nest and the rock wall; Water that flows down the rock wall, if dripping into the bird's nest, will also cause it to change color.

03 The stone cave where swiftlets nest nest is heated due to poor air circulation, and the higher the temperature, the faster the mineral oxidation and discoloration.

04 The bird's nests near the entrance of the cave are mostly pearl-white, and when you go inside, pearl-yellow and orange-yellow "yellow swallows" begin to appear, and when you reach the depths of the cave, you will see orange-red or gray-red bird's nests.
