Bird's nest pays attention to eating less and more meals, and keeps a regular diet. Dry bird's nest 3-5g each time, instant bird's nest 20-30g each time, once in the morning and evening, once a day or once every other day. Bird's nest food pays attention to "clear in the middle, soft in the middle." Generally, during eating bird's nest, eat less spicy and greasy food, and don't smoke or smoke less. Don't eat bird's nest during a cold, because the human body can't absorb bird's nest nutrition well.
The bird's nest, as its name implies, is the nest of swallows. However, this is not an ordinary swallow's nest, but a special swallow's nest-Jin Siyan. Jin Siyan is a bird, swift family. It is a migratory bird, which flies from Siberia and other places to natural caves along the tropical coast every year from 65438+February to March of the following year to breed. Jin Siyan is smaller than the swallows we usually see. Its back feathers are grayish brown with golden luster, its wings are pointed and long, and its four toes grow forward. This swallow has well-developed mucus glands in its throat, and the saliva it secretes can solidify into solids in the air, which is the main substance for their nesting. Jin Siyan lays eggs in March and April every year. Before laying eggs, they fly on the sea and high altitude every day, sometimes for several kilometers, breaking through the clouds, sucking rain and dew, eating insects, algae, whitebait and other things. After digestion, drill into steep, shady, high-altitude cliff cracks and deep holes, spit and nest. It will take about 20 days to build. Bird's nest in Yan Wu Li
The bird's nest is half-moon-shaped, resembling a human ear, with a diameter of 6-7 cm, a thick base and a thin profile wall, and weighs about10-15g. The nest has neat periphery and rough interior, like a loofah net. The whole bird's nest is white, glittering and translucent, elastic and attached to the rocky cliffs. Known as "precious medicinal materials" and "oriental treasures". The nests built by Jin Siyan for the first time were completely condensed by a large amount of mucus secreted by their throats. It is pure and hairless. This kind of bird's nest has the best quality and is the top grade of bird's nest. In the feudal dynasty, it was often chosen as a tribute, so it was named "Yan Guan". After the bird's nest pickers seized the opportunity to pick the bird's nest, Jin Siyan had to build a nest for the second time. Because the spawning season is approaching, Jin Siyan is plump, with a lot of jelly in his throat, and his nest is relatively fat. However, due to time constraints, they brought feathers and grass ... and mixed them with the jelly in his throat to build a nest again. It was rough, with many impurities and poor nutrition. The bird's nest collected at this time is called "Mao Yan". Another kind of bird's nest is wetted by the red liquid oozing from the attached red rock wall, and its whole body is dark red, also called "blood swallow" or "red swallow". It contains some minerals, has good nutrition and low yield, and is regarded as a treasure in bird's nest.
According to the nesting sites in Jin Siyan, it can be divided into cave swallow and house swallow. Dongyan: Swallows make nests in wild caves and coastal cliffs. The living environment of Siyan was destroyed because of early disorderly and indiscriminate mining and excavation. Now there are only bamboo ladders for picking in some caves in Thailand, and swallows have long been rare. With the scarcity of winter swallow production and the growing voice of environmental protection, it was gradually replaced by domestic swallow. Yanwu: From Dongyan to Wuyan, the nesting environment in Jin Siyan has changed, but the living habits have not changed. Jin Siyan is still wild. It goes out for food in the morning and comes back at night. Due to the artificial protection, Jin Siyan breeds more and more, and the built bird's nest is picked in time, with no loss of nutrients and better quality than Dongyan. The original ecological house bird's nest combines the advantages of "house swallow" and "hole eye" The combination of nature's primitive forest environment and "house swallow" technology effectively solved the internal and external environmental problems of bird's nest quality and formed a unique original ecological house swallow, which was natural, fresh and clean. Color: Blood Swallow, Yellow Swallow, Bai Yan. According to the specifications, it is divided into: Zhan Yan, Yan tiao, Yan Si, Yan Bing, Yan Sui and Yan Jiao. The nest of edible swift
According to the production form: grass swallows: small size, thumb size, small flight range, poor texture of grass swallows, some grass swallows contain nylon grass, which is actually caused by the inability of plastic bags to digest. High-quality grass swallows are mainly broken swallows, while inferior grass swallows have impurities and rough taste. Grass swallows are wild swallows and have strong adaptability to various environments. They are used to picking grass clippings and spitting out their saliva to build nests. When the grass is cut, the saliva condenses, and it becomes a nest for raising the next generation. Therefore, the nest built by this swift is covered with grass clippings. Therefore, grass swallows are easier to distinguish than other kinds of bird's nests, and are basically "grassy". This kind of swallow is common in Sulu Sea in the southern Philippines, so it is also called Philippine grass swallow. Mao Yan: The directly picked and untreated bird's nest is called Mao Yan because it is mixed with many feathers from Jin Siyan. This hairy swallow is different from the high-quality domestic swallow that has just been picked with a little hair, which is very different whether in the swallow house or in the wild. Light swallow can be turned into a swallow strip after hair removal. Heavy swallow used to wrap and dissolve bird's nest with stockings, but now it is broken and then depilated and added with working swallow cake or swallow strip. Some wool swallows need to use chemicals because of many impurities, unsightly colors, or re-adhesion, so there are few impurities, even if there is hair, but no chemicals are used. According to the shape: the swallow cup is intact. The swallows' cups after hair picking treatment are clean, with less impurities and good color. According to the completeness of the cup shape, Baiyan Cup can be divided into different grades, among which Super Bai Yan (Longya) is the best grade-the cup shape is big and perfect, and the fiber is tight; There is also a triangular swallow, which is a triangular bird's nest built by Jin Siyan in a corner of Yanwu. In the process of picking, packaging or transportation, many complete swallow cups are crushed and cannot form cups. Those thick bird's nests are called swallow strips. The taste of Yan tiao is slightly worse than that of Zhan Yan, but its nutritional value is the same. Because it doesn't have a cup shape, the sales volume is not good, so the price is lower than that of Zhan Yan. The nest of edible swift
Yansi Yansi is a thin strip that workers will drop when picking wool, and then pack it. Because its shape is more broken than swallow silk, it is filamentous, so it is called. The taste of shredded Yan is worse than that of Yan Yan and Yan tiao, and it is very broken after stewing, with more impurities than that of Zhan Yan. The price is lower, which can meet the needs of low-cost consumer groups. There are also swallow nets, balls, pieces and pieces made of swallow silk. In the process of processing, most of them are made of edible gum, so the price is lower. When the dovetail angle is trimmed, the irregular part of the dovetail angle is trimmed into an angular shape, so it is called the dovetail angle. Because the swallow horn is the horn of the swallow cup, the texture is hard, so it is chewy, but it has less hair and takes a long time to soak, generally more than 10 hour.
