Inferior nitrate of Hong Kong bird's nest exceeds standard The expert soaks while claiming that needs to be long before eating
The University of Science and Technology of Hong Kong finds, the thousandfold that swallow's content of inferior nitrate of blood is the sauced salted vegetables standard, need to soak the news reporter Wang RiJing in the south and release from Hong Kong inland citizens and like going to Hong Kong to buy the bird's nest for a long time before eating, but the newest sample survey of research and development centre of traditional Chinese medicine of Hong Kong University of Science and Technology is found, Hong Kong the intersection of business and all the intersection of bird's nest and sample inferior the intersection of nitrate and content exceed standard, the most serious swallow's content of blood is even up to 20,000 milligrams / kilogram. However, the expert don't think that need to worry, so long as soak the time long enough with the fresh water before eating, can reach the edible standard of the security. Include inferior nitrate in the natural bird's nest too and is entrusted by Hong Kong professional bird's nest trader, Hong Kong traditional Chinese medicine research and development centre of University of Science and Technology gauges 47 bird's nest samples bought at random, and announced the latest investigation result yesterday. The examining report reveals, the samples all contain inferior nitrate, there is content of inferior nitrate of some bird's nests that goes beyond the safety standard, especially blood swallow, each kilogram of most serious content of inferior nitrate of sample is up to 20,000 milligrams. The traditional Chinese medicine research and development centre of University of Science and Technology of Hong Kong says, in the bird's nest sample bought on the market, inferior nitrate is not added manually on later stage, but natural inferior nitrate with different content. Inferior nitrate to not intending to add, produce naturally, the country " standard with a limit on quantity of pollutant in the food " (G2762-2005) Stipulate, it puts a limit on quantity to be 3-5 milligram each generally, sauced salted vegetables of height it puts a limit on quantity to be 20 milligrams / kilogram only even the most. Doctor of University of Science and Technology of Hong Kong life sciences department Karen Chen participates in this research project, he reveals all reporter southwards, besides 47 samples of the business, the research and development centre has also collected several dozen bird's nests in the pure nature environment from the cave of Indonesia, Malaysia and other places. "The content of inferior nitrate in these natural bird's nests hardly differs from what has been bought on the market. " The research and development centre says, it is not strange that the bird's nest includes inferior nitrate, the swallow excrement and urine may cause pollution to him too. Can eat to boil safely to stew to soak for a long time though the content of inferior nitrate in the natural blood swallow may be frightfully high, but the expert says citizens do not need to be anxious. Preside over this time life sciences department professor and concurrently traditional Chinese medicine director of research and development centre Zhan HuaQiang of University of Science and Technology of Hong Kong surveying and studying it say: "The bird's nests, like vegetables, are all food raw materials, though contain nitrate and inferior nitrate, but not terrible, after dealing carefully with and stewing and boiling, such as soaking for more than 3 hours with 100 times of fresh water, and then wash twice with the fresh water, stew and boil for more than 30 minutes, can eat safely. " "It is a blood swallow that nitrate and inferior nitrate is the highest, aptest to exceed standard. We soak the bird's nest in water, white swallow is all right within very short time, because the quantity that itself exceeds standard is very low. After swallow soaks the blood for 15 hours, we find even the content is the highest, the majority of inferior nitrate can be removed. " Zhan HuaQiang says, white swallow can remove the majority of inferior nitrate in 15 hours when soaking for 3 hours, yellow swallow 10 hours, blood swallow, reach the edible range of the security.
