Among the three nests of swiftlets among the people, the other one was removed due to the nest, only to see the nest again in despair. A more reliable statement is that in fact, the blood swallow is made from a bird's nest in a cave built on the cliff. It has the general shape of a hand and a half. We also think of it as holding water, but also because of the changes in different environments and connections, it is mainly 1/4 ball. shape or triangle. There are three main reasons for colored nests: First, swiftlets eat mountains of seaside algae, flying ants and other insects, so the minerals contained in their saliva are more likely to be oxidized in red nests; second, mine rocks include nest materials that have been passed through for many years and The contact surface of the rock slowly penetrates into the nest, and the natural mineral water in the cave drips into the nest, resulting in a color change; third, the air in the cave is very hot, and the deeper the cave is, the more stuffy it is and contains minerals. It is the oxidation change of the sultry air or the clarification of the red-grey-red bird's nest. According to people who have climbed the mountain nests, the nests on the outer periphery of the cave pearls are all white. As you go further in, the pearls start to build yellow and orange (yellow rock) nests on the cliffs, and then they reach the deepest and hottest cave belly. I only saw orange-red bird's nests. Please note that it is not bright red, orange or gray, but red. The bright red blood swallows on the market now are smoked. Yan is not so natural blood red, reddish brown dry also, but has the unique smell of swiftlet (the caves that produce hundreds of thousands of bird's nests, there are only a few caves in Sabah blood swallow). Most of them are produced in Thailand's Roland Rock, Constance Mountain, Songkhla Mountain and other places.

In August 2011, the Zhejiang Provincial Administration for Industry and Commerce leaked news that the nest authorities found problems through bird market sampling, with 90% of the high blood swallows, including "Eagle King Brand", "Yanxian" House" and other major brands. In these blood swallows, the toxic substance nitrite content exceeded the legal limit by up to 350 times. It is reported that these problems come from Blood Swallow Malaysia. After analyzing its raw materials, it is not difficult to find that the blood swallow has been smoked and disinfected using glue, additives and bird droppings. Industry experts point out that such "poisonous blood swallow" food will cause great harm to human health and even lead to serious diseases such as gastric cancer and esophageal cancer. Regarding these issues, some insiders have revealed the true source of blood swallows. For example, Malaysian Deputy Minister of Agriculture and Agro-Based Industry Chua Chi Yong once said that "there are no blood swallows in the market" and these merchants are selling so-called blood swallows with an extra "dyeing pigment." In addition, the chairman of the Bird's Nest Federation of Malaysia, Ma Xingsong Make the same point. He also pointed out that the problem of blood swallows was eliminated in the market and the reason why merchants made huge profits. In the past two months, the Zhejiang Provincial Administration for Industry and Commerce has carried out a special inspection of the bird's nest market. 491 blood dealers sampled swallows, and 537 batches of swallows were collected. The results showed that the nitrite content in the blood swallow samples seriously exceeded the standard.Black nest endangers national health. On August 15, the Zhejiang Provincial Administration for Industry and Commerce announced the results of law enforcement: retail stores across the province participated in the problem of blood yanda reaching 200,000 grams, approximately more than 30,000 lamps, and the average nitrite content sampled was 4,400 mg/kg, the highest Nitrite content up to 11,000 mg/kg. Zheng Yumin, director of the Zhejiang Provincial Administration for Industry and Commerce, said that these "artificial blood swallows" containing a large amount of nitrite can cause harm to the human body after consumption. Excessive intake can cause poisoning or even death, and long-term intake can increase the risk of cancer. Relevant law enforcement officials said that the "problem blood swallows" sampled mainly came from Malaysia. What is bird's nest? The swiftlet spat out a mouthful of blood from her daughter's worth. In the stage of advanced nutrition, expensive blood swallow has always been accompanied by such a legend. According to preliminary statistics, the sampling involves the entire province of Zhejiang Xueyan retail stores. Guangdong, where the "Yinghuang" brand blood swallow of the Yinghuang Ginseng and Antler Products Co., Ltd., the "Yanzhijia" brand of Xiamen Food Co., Ltd.'s thick silk thread, and the "Active Base" of Guangzhou Kang Pharmaceutical Co., Ltd. Brand blood swallow, "Victor Tang" brand of Beijing Qinghetang Ginseng and Antler Co., Ltd., the highest nitrite content detected in 11 batches of blood swallow products exceeded 10,000 mg/kg. According to Zheng Yumin, there is no blood lead in the house. Yan Yan, what they call human hematopoiesis has an inevitable connection with the serious excess of nitrite detected. The national mandatory standard (GB2760-2011) "National Food Safety Standard for Food Additive Usage Standards" limits the addition of nitrite to only allow the production of cured bacon and other products, which has a trace residue limit of 30 mg/kg, and the highest residue limit is smoked ham. More than 70 mg/kg. Comparing the limits, in the largest sample of bird's nests, the nitrite content exceeded 350 times. Zhejiang Province has launched a large-scale operation to investigate fake blood swallows and is also resistant to counterfeiting. On July 26, the association held a "Malaysian official press conference" in Hangzhou. Two parties claiming to be from the Malaysian Endangered Species Import and Export Management Agency and other agencies made so-called "clarifications" on the issue of nitrite in blood swallows. . After verification, the identities of two Malaysian officials were suspected of being falsified. Regarding this, Zheng Yumin said that they were not refuting the rumors but making them up. The identity of its officials was suspected of falsification, but they issued a blood swallow test report and among the 35 items, none involved nitrite content. Zheng Yumin emphasized. "As long as bird's nests are exported to China for sale, they must pass mandatory basic food safety standards, and the toxic substance content in China's national standards should be less," Zheng Yumin said. In Malaysia, there is a large bird's nest industry with an annual output value of 2 million yuan. , the first bird house with more than 50,000 rooms, 95% of which are exported to China. "So the Chinese market is in trouble, and they are worried, especially with people who are very anxious about their interests, that I will make a fool of myself in a hurry." Relevant experts said that fake blood swallows are not only sold in Zhejiang. The reporter learned from the State Administration for Industry and Commerce that on the 16th, the State Administration for Industry and Commerce has notified all localities to concentrate time and law enforcement forces to increase inspections, inspections and investigations in the bird's nest market; operators found to have nests that do not meet food safety standards should be ordered to stop selling. The shelves will be delisted, and the enterprises will be investigated and destroyed according to law to prevent them from entering the market again
