Blood -colored bird's nest is "sorrowful"? It is actually the result of environmental oxidation and fermentation

　　Data show that China ’s bird's nest consumption was thousands of tons in 2018, but only more than 100 tons imported through customs formal channels. It is an indisputable fact that bird's nest is becoming more and more civilian, but do you understand some of the bird's nest rumors rumored?

　　It is generally believed that bird's nest refers to the saliva secreted by several golden swallows of the Swift Swift and Golden Swallows, and then mix the nests made of other materials. Ma Zengjun, the president of the National Municipal Agricultural Trade Center Federation, believes that bird's nest is condensed from liquid secreted by the tongue, and it is not the saliva that people usually understand. "In addition to several kinds of swallows that can secrete this type of liquid, other swallows also use saliva to make nests, but it cannot be called bird's nest." Ma Zengjun said that only Indonesia, Malay, Thailand, and Vietnam can produce bird's nest, but my country It is currently not imported Vietnamese bird's nest.

　　So how did Bloody Yan come from? Will the liquid secreted by the tongue adenal transform the blood and produce bleeding swallows? The natural growth environment of Swift is in the cave. Some reports show that those who climb the bird's nest mountain introduced that they arrived in the deepest and sultry cave belly, and they saw red -brown bird's nest.

　　"Bloody swallows are due to the result of bird's nest in a sealing hole, and due to the result of high temperature and humid environment oxidation and fermentation." Sun Li, an associate researcher at the Institute of Inspection and Quarantine Sciences, said that his nutritional components would not be higher than the regular bird's nest.

　　Earlier, in order to obtain higher profits, the merchant created a gimmick of blood swallows, claiming that the blood -colored bird's nest was made by the "sorrow". With the significant increase in market demand, driven by huge profits, illegal merchants have fumped bird's nest through swallow manure, or chromosomes such as Sudan Red make blood swallows. "Bloody swallows have been fired to 10,000 yuan, but there is no so -called blood swallow." Xu Jing, general manager of Jingdong Health and Nourishing Health Business Department, said that artificially smoked bloody nitrite content exceeded the standard by 350 times.

　　Although the current sales of bird's nest are hot, some experts have said that the nutritional value of bird's nest needs more experimental data certification.
