[ Abstract] Recently, a Weibo who questioned "Gabon ash in Lanzhou Lamian Noodles may cause cancer" caused a heated discussion on the Internet. Some people question whether the plaster added to Lamian Noodles has been used for hundreds of years, and is it really harmful to health? Different from every food safety incident, many media people came forward to clear Lamian Noodles's name this time. Some gastroenterologists say that if there is only a small amount of arsenic in the ash, plus the natural metabolism of the body, it will not cause too much harm to health. [Let me say a few words ]\xd\ Yangcheng Evening News Reporter Yin Anxue reports: In the early morning of 26th, a Weibo questioned that penghui was added to Lanzhou Lamian Noodles, which may cause cancer. This Weibo was quickly forwarded. However, many media people and netizens stood up for Lamian Noodles in Lanzhou and thought it was safe to eat Lamian Noodles in Lanzhou. The relay of media people made the news of "Lu Bianshe" turn off. \xd\ A rumor set off the topic \xd\ Yesterday morning, the "Dilmac official" reported in Weibo that in order to make Lamian Noodles more flexible, all Lanzhou ramen noodles are using ramen, and the main ingredient of the ramen is Peng Ash, which contains a lot of carcinogen arsenic. Now Lanzhou and Lamian Noodles all use this preparation to make flour more elastic. If the putty is put into a paper cup, it will be oxidized, and if the ramen solution is poured on the smooth floor, it will be even more horrible. \xd\ The news quickly triggered a hot discussion among netizens, and nearly 2, comments were forwarded within one hour. With the increasing forwarding volume of the Weibo, more and more netizens are participating in it. Some people question whether the penghui added in Lamian Noodles has been used for hundreds of years, and is it really harmful to the health? \xd\ Some netizens began to worry about the safety of Lanzhou Lamian Noodles. Someone also broke the news that Lamian Noodles in Lanzhou, another province, may not be owned by Lanzhou people, which is not authentic and hygienic. \xd\ However, many people from all walks of life who have studied, lived and worked in Lanzhou have come forward to defend Lamian Noodles in Lanzhou, especially Ma Jun and Wang Keqin, who work in the media, have frequently posted Weibo, arguing vigorously, making the wind vane of online public opinion become the protection of the traditional food of Lanzhou Lamian Noodles. Some netizens feel that every time food insecurity is exposed, some enterprises can always be defeated. But this time, I failed to scold Lamian Noodles in Lanzhou. \xd\ The media renamed Lamian Noodles \xd\ Ma Jun from Gansu TV Station saw the controversial Weibo, and in the early morning, he immediately renamed Weibo as Lanzhou Lamian Noodles. \xd\ "We didn't die after eating it, okay? We've seen those who died, but we've never seen those who were poisoned." Ma Jun said that he was deeply puzzled and angry to hear that someone was spreading the poisonous rumor of Lanzhou Lamian Noodles on the Internet. \xd\ Ma Jun introduced that the traditional technology of Lanzhou beef noodles pays attention to "three times of water, three times of ash, and 9981 times of kneading". Among them, ash refers to Peng ash, which can make the pulled noodles smooth and yellow and strong. Later, the process was replaced by a ramen agent, which is to purify the ash and get rid of harmful substances. At present, the Lanzhou market uses the ramen agent developed by Lanzhou University, Jiaotong University and related enterprises, and has passed the relevant safety certification. \xd\ Wang Keqin, a famous investigative journalist in China, studied in Lanzhou and is very familiar with Lamian Noodles in Lanzhou. He said that he had lived in Lanzhou for more than 2 years, and he ate a bowl of Lamian Noodles almost every day. Sometimes breakfast and lunch were all beef noodles. Beef noodle shops are generally small, and there are many eaters. They can't sit in the noodle restaurant, and everyone will squat on the street with their faces. It snows heavily in winter, and the most enjoyable thing is to squat in the snow. Goose feather flakes are floating in the bowl, but the heat in the bowl is rising. \xd\ "Lu Bianshe" news disappeared \xd\ Some netizens analyzed that people didn't know enough about food safety when they used to make noodles with bitter fleabane ash. With the development of science, there will be no problem with the ramen developed by Lanzhou University, but the hygiene of ramen noodle shops in other provinces is really worrying. "Lamian Noodles, Lanzhou is a business card of Lanzhou. When people from other provinces associate the mess with Lamian Noodles, Lanzhou, it is really uncomfortable to be a Lanzhou person." \xd\ Some people applaud Ma Jun: As a media person, after the news of "Lu Bianshe" came out, he knew the truth at the first time and announced it. Unlike some media people, they do news for gimmicks. Our nerves have been scared tight enough by food safety, so don't spread the news of "Lu Bianshe". \ xd \ At 1 o'clock on the 26th, the reporter couldn't find the "Dilmac official" on the Weibo, and his Weibo was closed. Some netizens said that "Dilmac officials" should feel guilty. Can Lanzhou farmers who have been Lamian Noodles for generations afford to be injured? \xd\ Yin Anxue \xd\ Sohu Health Supplementary Reading: \xd\ Peng Hui is neither a food additive nor a food raw material \xd\ Nong Shaozhuang, a food expert and professor of dalian polytechnic university Food College, said that Peng Hui is neither a food additive nor a food raw material, but a traditional ramen noodle. It's made of Pennisetum and its main component is potassium carbonate. At present, one kind of Peng ash used in the market is made of Peng grass, and the other is prepared by enterprises according to the composition of Peng ash. Traditional Lamian Noodles in Northwest China uses Peng Ash, which can increase the elasticity of noodles. \xd\ Trace arsenic in Peng Ash is harmless to people, but excessive arsenic will cause poisoning \xd\ According to Zhao Guohua, dean of the School of Food Science of Southwest University, Gabon Ash in Lamian Noodles is a method handed down by the people, and this talent must be added to Lamian Noodles in Lanzhou. Peng ash contains lead, arsenic, hydrogen sulfide and other chemical components, whether it is baked by natural vegetation or artificially prepared Peng ash, it may cause certain safety hazards to the human body. Zhao Guohua said that the relevant national regulatory agencies should conduct a safety assessment on the production technology, production standards, scope of use and content of Peng Ash, so as to eliminate the panic of netizens. \xd\ Wang Lei, deputy director of the Department of Gastroenterology, xinqiao hospital, said that lead and arsenic have certain toxicity. Arsenic, for example, exists in various forms, and there will be poisoning symptoms unless it is ingested in excess. In addition, the toxicity of arsenic mainly affects the blood system. Wang Lei said that if there is only a small amount of arsenic in the ash like Peng, and the body's natural metabolism, it will not cause too much harm to health. Unless it is excessive intake of arsenic, it will cause chronic poisoning.
