What is the best bird's nest?

Bird's nest is not the best. The so-called best is just the promotion rhetoric of the merchants. Some early dictionaries, such as Nutrition Encyclopedia, recorded: "After the second nest was taken off, the third nest made by Yan near the spawning period was called blood bird's nest because the gum spit contained bloodshot blood." Therefore, it is constantly criticized by environmentalists and believers. In fact, Jin Siyan is very rich. A pair of swallows can lay eggs three times a year, while each Jin Siyan can build a bird's nest three times a year at different times. But the blood swallow is not the result of Jin Siyan vomiting blood, because the red hemoglobin will only be oxidized to dark brown methemoglobin. Blood swallow is related to the consumption of coastal algae and insect food in Jin Siyan. Blood swallow is not as expansive and fragrant as Bai Yan, but it has higher mineral content, so it is more expensive because it is scarce. The difference between bird's nest and its quality lies in six indicators: origin, origin, completeness, cleanliness, taste and moisture content. 1. Indonesia's bird's nest accounts for 80% of the world's total bird's nest production, Malaysia 13%, Thailand 5% and Vietnam 2%. There are three domestic bird's nests: Yanyan in Huaiji County, Zhaoqing City, Guangdong Province, Yanzidong in Jianshui County, Honghe Prefecture, Yunnan Province, and Dazhou Island, Hainan Province (only two bird's nests were collected in 2002, and only 15 Jin Siyan was left in September 2006). Due to its proximity to the Tropic of Cancer, the collection of bird's nest is seasonal and the output is scarce, with the total amount less than one tenth of the global output of bird's nest. A large number of people in Southeast Asia go to caves to collect bird's nest, which is not only extremely dangerous, but also plunders nature after they collect caves. On the cliffs of several small islands in Thailand, many rotten bamboo ladders lead to caves once rich in bird's nest. Now these caves are abandoned, and Yaner is gone. With the increasing calls for protecting nature, the Yanwu invented by Indonesian Chinese came into being. The structure of these swallow houses is no different from that of ordinary houses, but raising swallows is not raising birds. Swallows are still wild and feed on their own. The house is only used to attract swallows to live together, so that swallows can nest in the house and collect a large number of bird's nests. The bird's nest in the swallow house with environmental awareness will not be picked until 18-24 days when the swallows hatch and fly in 45 days. Jin Siyan went back to the house and built a new nest, which was handed down from generation to generation. Environmental protection swallow is cleaner, smoother, whiter and more delicate than cave swallow in harsh environment. Second, the hair head "hair head" is calculated by weight. The greater the weight difference between the soaked bird's nest and the dried bird's nest, the better the "hair head". Generally, high-quality bird's nest has 6 to 8 times the "hairy head". The origin, location, picking season, processing technology, dry humidity, soaking season, room temperature and water temperature, and even the difference between morning and evening, hair will be different. However, some netizens sent the "bird's nest" bought in a bird's nest monopoly from Guangzhou. When they opened the envelope, they smelled a pungent chemical smell. I took a small piece, which expanded hundreds of times and was solid and granular. It was really terrible. Third, the degree of completeness is to remove the hair and clean up the selected bird's nest. It is not easy to keep the bird's nest clean and intact. In Emerald Jade, Liang Yiqing spent three years trying to carve the treasure ship that Zheng He brought back to the Bird's Nest, and finally failed. Swallow washing workers of high-quality brands of bird's nest are equally conscientious and dare not slack off. A good face-washing master is often trained from an early age, not only to master exquisite finger magic, but also to pay attention to "eye-to-eye, hand-to-hand, heart-to-heart" like a gem sculptor. Only the first-born swallows are selected for high-quality super swallows, which are complete and full, dense in texture and crystal clear in color. It is the ultimate enjoyment of high-quality living art. The cleanest, most complete and best-quality bird's nest must be the most attentive bird's nest. Fourth, clean quality If there is no carefully cleaned bird's nest, no matter swallow, swallow strip, swallow net, swallow horn, swallow slice, etc. There are swallow hairs, and there may be impurities such as eggshells and beetles. Buying this furry bird's nest is like buying a diamond and cutting it yourself. Consumers will really pay for it. Cleaning bird's nest is time-consuming and laborious, and there is no other way but to choose it patiently by hand. A novice can't pick one lamp a day, and a skilled person can only pick three or four lamps a day. Please read Bing Yi's personal experience on bbs: "In recent weekends, my wife and I spent almost half a day cleaning the Bird's Nest. Although it is an official swallow lamp, there are still many hairs, occasionally seaweed and sand. Even if you pick it with a needle, you are very tired. " The netizen replied that nothing happened. Someone replied, "Eating bird's nest like eating fish, sneaking in is pure bird's nest, isolating what you want to get through, just like eating fish and spitting bones." After dinner, the palms are all hairy. " Someone even replied, "The way to be lazy is to eat wool." Moreover, the water soaked in this kind of bird's nest has to be poured out repeatedly, but the nutrients of bird's nest are all dissolved in the water, so it is a pity to pour it out, just like soaking American ginseng, pouring out the ginseng soup and eating only ginseng slices. Therefore, buying bird's nest with hairy impurities is not worth the loss. Some vendors washed it with medicine and stirred it with a stick, and the swallow hair immediately floated to the surface, but no one dared to eat such bird's nest. The best way is to buy high-quality clean bird's nest of international brands. Large Yanwu factories usually have hundreds of swallow washing machines. The natural and safe way to wash swallows is that a skilled swallowwasher picks 7-8 bird's nests with clean water and tweezers every day. Except Baiyan Cave and Baiyan Mao Bird's Nest Factory, the rest are high-quality clean bird's nests. Fifth, high-quality bird's nest tastes delicate and smooth. If the water for stewing bird's nest is sticky, it will often be coated with glue or thickened. Different grades of bird's nest have different tastes: the special swallow cup Q is smooth and supple, which is extremely enjoyable. Bird's nest net is the "Yan 'an" part in the middle of bird's nest, and it is a slender net that supports eggs and Xiaoyan. The taste is delicate and easy to digest and absorb. Yanjiao is the part used by Jin Siyan to fix the two ends of bird's nest. It is the "load-bearing beam" of the Bird's Nest. Thick, refreshing and chewy, and the stew takes a long time. It is the concentrated part of bird's nest nutrition. 6. There are many bird's nests with high water content in the market. This kind of bird's nest is extremely cheap, but it is a mixed bag. The highest water content of true bird's nest can reach 40-60%. Even if it is stored in a wooden box or moistureproof box, it will still go bad, just like the so-called "golden jade is outside, but it is ruined" in The Word of Orange Water. High-quality bird's nest will not be moldy even if it is not put in a wooden box. Buying high-quality international brand bird's nest from famous shops is the best shortcut to prevent bird's nest from becoming moldy. 7. What is a good instant bird's nest? Top grade instant bird's nest is crystal clear. After the ready-to-eat bird's nest bottle is tilted at 45 degrees, there is not much water, and the bird's nest is crystal clear and delicate. High-quality ready-to-eat bird's nest (Bai Yan) has unique bird's nest collagen, which is rich in flavor after opening a bottle. Because Jin Siyan eats algae and insects on the seashore, the taste of stewed blood swallow is not as rich as that of Bai Yan, but the mineral content is high. The instant bird's nest stewed by exquisite craftsmanship has a smooth and elastic taste. Natural ready-to-eat bird's nest should be marked without preservatives and additives.
