Ji'nan bean sprout market shady: bean sprouts soaked in insurance powder or carcinogenic
Author: Sun Hao Chen Jianfeng source: city girl
bean sprout is a favorite dish in people's life, but it may not be known that the common dish also has some secrets.
Zhang Mei, who once sold bean sprouts, reflects that the traditional method of producing bean sprouts is expensive and not very good. To this end, some people in the process of raw bean sprouts, the use of a substance, making the bean sprout white and fat, attractive, which is the "beauty bean sprout" we often see in the market.
color and lustre bean sprouts very popular
we found in a wholesale vegetable market in Ji'nan, we found that the bean sprouts sold here, whether it is green bean sprout or yellow bean sprout, are mostly white fat and bright, the seller confessed that "there is a secret recipe".
what secret recipe can make the color of bean sprouts become so uniform and good-looking? Then, we told the situation to the Ji'nan agricultural supervision team. "The powder is coming again." The team's staff are worried.
what exactly is the powder? An expert on Applied Chemistry says that the substance is an industrial acid, toxic, and long-term food can cause cancer.
the puzzled bean sprout did not sell
in January 16th, a friend who worked in the food and Drug Administration recommended us to know the old bean sprout.
old three said that 4 years ago, he could sell nearly a thousand pounds of bean sprouts a day, when bean sprouts were long and thin.
but in recent years, a group of outsiders came to Ji'nan and began to distribute "looks" more tender roots without bean sprouts. This kind of bean sprout is quickly favored by Ji'nan citizens and some organization units and school canteens. The business of the old three is falling down and some of Ji'nan's peers are also selling "fat bean sprouts".
at the beginning, the old three tried to produce some bean sprouts with the soil method, but the sprouts were small, low yield and bad selling. In September last year, the old three spent 2900 yuan on the "technology" to their peers, but after learning "technology", the old man decided to quit.
"is the use of medicinal water bubble out, 500 grams of bean sprout, put about 1.8 grams of insurance powder, bright color, but also to remove impurities, but can not eat. The old man said that although he had no culture, he never did anything else.
the best selling secret "no feeding" bean sprouts no one eats
the third secret, which has lifted our curiosity.
under his suggestion, at 7 a.m. on January 17th, the reporter came to a vegetable wholesale market in Licheng District. In the market's southern wall, mung bean sprouts and sprouts are stacked up like hills.
there are 11 wholesale bean sprouts in the market, most of which sell both yellow bean sprouts and mung bean sprouts. The bean sprouts are all root free and white fat, and "wash white bean sprouts" with the old three.
when we asked why there was such a thick bean sprout, "there's a way." The elder sister was pleased with her face. "This bean sprout can be measured. Generally, 3 or two half will be able to fry a dish."
we continue to ask. She looked at us as if she were looking at her identity and did not answer. After many of our "consults", she confided some of the things - "it would add a kind of powder, good use, hydration, and soak the bean sprouts in it." It can't be used for 10 minutes. The color is bright and the shape is beautiful. This stuff is in the wholesale market, and many bosses are using it. "
she regrets that no bean sprouts are fed because they are not beautiful enough.
is the Secretary General of the Ji'nan Food Industry Association, which is easy to get
, said Liu Qingnian, the vegetable market in Ji'nan indeed has unlawful peddlers to use bleached vegetables. He said that the sulfur powder contained in the insurance powder can play the role of bleaching and sterilization, and the color of the soaked vegetables is white and the shelf life is longer.
common practice is to add industrial raw materials in water to two sodium sulfite and sodium sulfite to soak bean sprouts. The two industrial materials used are commonly known as insurance powder. It is a chemical preservative, widely used in papermaking, textile printing and dyeing industry, and can be bleached. "Insurance powder has the nature of decomposing sulfur dioxide in water, and if it is used to soak and bleach, it will certainly cause great harm to the body." Liu Qingnian said.
among the technologies circulated among the growers, it is also necessary to follow the strict operation process - not more than 2 grams, and the excess may cause the vegetable to burn, and it will also cause significant harm to the human body.
in 2008, a certain type of plant owner in Guangdong did not follow the operation procedure, adding excessive amount of insurance powder to the vegetables, causing many people to be poisoned. The incident sparked a severe campaign against the government's insurance powder. The powder was turned into the ground.
but the experience of old three shows that the powder is still lingering. People can easily get a lot of insurance powder, and some peddlers are also hungry and eager to buy it.
the composition of the big bottom and the wash shrimp powder is industrial acid
for further understanding of the powder, we also interviewed the chemical researchers.
Du Wenyu, director of the Shandong Food Research Institute, said that in the powder, even two sodium sulfite content is generally 20%, this product is industrial grade, the toxic to the human body is quite large, may affect the human vision, damage the liver and intestines and stomach. Serious will cause poisoning, the greater the impact on children, and even affect intelligence. This bleach will accumulate in the stomach and cause cancer.
"insurance powder", like last year's stir fried shrimp powder, is industrial raw acid. The so-called "powder", its acid content may be higher than "shrimp powder".
Wei Qin, Professor of chemistry at University of Jinan, also said that heavy metals contained in the "insurance powder" may remain in the human body for a long time. She emphasized that vegetables such as bean sprouts were not included in the processing area.
everything around money to preserve "beauty"
"people will think about how to increase income, all around the money." Du Wenyu said that today's vegetable traders catch up with the good times, and "science and technology are developed and problems can be solved."
we contacted a manufacturer of insurance powder in Yantai in the name of vegetable seller. The manufacturer's sales person said that the insurance powder they produced was mainly used for preserves and sweets.
when we asked whether the powder could be used to bleach the bean sprouts as well as the specific dosage, the person in charge said that some peddlers who sold bean sprouts had bought them and said the bleaching effect was good. She also said that the insurance powder available for this kind of food is much smaller than that used in industry.
in the conversation we learned that the people of the insurance powder manufacturers also understood that their industrial insurance powder was used in the food industry.
maybe the elder sister is good, and the purpose is to not offend his own customers, but her kindness has given the green light to those who use industrial vegetables and fungi. Her statement is also surprising: "a lot of dealers sell them to the food factory. That's their business. You'd like to sell it, you make white powder with it, no matter what I do."
buy back to do experiments like laundry powder, a very white
we bought this "insurance powder" at a chemical store in the Tianqiao East. Female owners say dry cleaners often buy clothes to avoid color mixing. As for the whitening and freshness keeping of vegetables, she said it was not clear, just told us that this material was very bright and clean.
opening the bag, a smell is coming. We pour the white powder into the paper cup and add a small amount of warm water to make the blending. When the warm water comes into contact with the powder, it immediately reacts, and a large number of white bubbles are surged in the paper cup. It's kind of like washing powder, but it tastes more pungent.
later, we will buy bean sprouts from the market and immerse them in a liquid mixed with the insurance powder and water. Before the soaking bean sprouts, the color is black, and there are many impurities on the neck. After soaking for about 20 minutes, the bean sprouts were "very happy" and began to become bright and full. The impurities on the vegetables were also bubbling down, better than the pollution-free bean sprouts placed beside them.
after about half an hour, the bean sprouts that had been soaked were thicker. The pollution-free bean sprouts were thinner and longer. Subsequently, the difference between the two bean sprouts became more and more obvious. The sprouts sprout longer and the more beautiful, and the pollution-free bean sprouts appear more "rustic". What
surprised us is that the bean sprouts are still the same as fresh ones all day long, and pollution-free bean sprouts have long been withered.
workers in Ji'nan's pollution-free bean sprouts production base also conducted soaking test on soybean sprouts. After testing by a scientific research institution, the pH value of this "safe powder" is 2.5, which is a strong acid substance.
the experimenter stirred the water with his hand and felt pain and itching immediately. "It is safe to say that these insurance powders are all made up by people." The testers said.
let a few readers to sell well, everyone chose to bubble
then, we found 5 female readers, the soaked bean sprout after the supermarket to sell the pollution-free bean sprouts sold together, let them choose. In advance, 5 readers who did not know about it chose 4 soybean sprouts after soaking, and only one chose pollution-free bean sprouts.
Ms. Feng, who has been soaked in bean sprouts, is a housewife who has many years of experience in buying vegetables. She says the bean sprouts are bright and tender, and the taste must be crisp. Ms. Wang, who also chose the bean sprouts, said that she bought bean sprouts mainly by looking at new stale, dry, and sprout sprouts that met the criteria she chose.
the only woman who had chosen no pollution-free bean sprout, said she had heard about the bleached bean sprouts. She had carefully picked up some of the bean sprouts that sold each other, and felt that the soaked bean sprouts had a little odor. And she also heard that this bean sprout broke the neck after a lot of water, personally proved this, so she chose the supermarket selling pollution-free bean sprouts. "The steeped dishes do sell faster." Yesterday morning, when we came to the wholesale market for second times, a vegetable vendor named Guo said.
generally, the storage period of vegetables is relatively short. Generally, it can only be stored for more than 1 weeks, and the storage time of insurance powder bubbles can reach 3 months or even longer.
seafood also hide secret bubbles 10 minutes, crab belly wash snow white
in Ji'nan a seafood processing enterprise product insurance director Ceng Yu, said that white bean sprout is not an example. "Not only bean sprouts, but many good potatoes, yam and other vegetables, including rice cakes sold on the street, and even seafood, may be used for insurance powder."
under the guidance of Zeng Yu, we came to an aquatic product market in Shizhong District. Here, the powder is used by some people to do his way.
among them, a Liu surname boss is a friend of Ceng Yu. While he was smoking a cigarette, he used a large bucket of blister crabs and bleached with insurance powder.
we can see that the crab shells were black and dirty at the beginning, and some of them were entangled with black impurities.
boss Liu ordered the workers to remove two packets of white powder from the store, first adding a salt like powder and adding MSG like crystals. "This is the two kinds of special kimchi powder, a 10 yuan a catty, a 8 yuan, two kinds of reconciled washed crab, are very bright and clean."
see only the workers add water and dirty crabs in a bucket, pour "powder" into the stirred, and take it out for about 10 minutes. The original color, black and dirty crab, only become bright and clean. Especially the crab belly, wash snow white.
Liu boss said: "a pound of powder plus 100 Jin of water, water can be used repeatedly. Soaking can wash away all the dirty things. But when you pick up it, you'd better wash it with tap water, otherwise you will easily smell the powder.
traders also revealed that spraying the powder solution on the surface of kelp can make kelp green.
their behavior was also exposed to the media, and boss Liu was angry about it. He complained about the embarrassment of life - if you don't have to do it, "do you want to do it?"
asked five regulators, "no matter insurance"
Yesterday morning, we soaked bean sprouts on the insurance powder and dialed the 12315 report hotline in Ji'nan. On duty, the business department said that the industry and Commerce Department was only responsible for managing the problems occurring in the process of food circulation. For the bean sprouts soaked in the vegetable market, she recommended that the reporter dialed the quality and technical supervision and food medicine. Product supervision hotline, if the results of these two departments prove that bean sprouts have problems, the trade and Industry Bureau can check the traders in the market.
staff of the Municipal Food and Drug Administration said that the bean sprouts that had been bought by the food market were not managed by them. They only tested the food in the restaurant or the canteen, and the bean sprouts should be managed by the industrial and commercial departments. The reporter said that the Department of industry and Commerce required the food and drug administration to issue the test results to investigate, the staff said that they have not yet detected the equipment of the insurance powder, and called the Quality Supervision Bureau to test it.
later, the reporter dialed the hotline of the provincial quality and Technical Supervision Bureau. A staff member said that soaking bean sprouts with chemicals is illegal, but sales problems should be supervised by the industry and Commerce Department. The reporter said he wanted to do a test on the bean sprouts he bought, and the staff said that the city quality inspection institute could do the tests, but at their own expense.
Ji'nan Quality Inspection Institute staff said that testing two sodium sulfite required related qualifications, and they did not do the related tests, so they could not be tested.
the staff of the Ji'nan agricultural supervision team said vegetable merchants used illegal additives to their management, but the related tests of the additives were very complex and time-consuming, and they were not qualified to detain. Many illegal traders fled before the test results were not available. "Food safety regulatory system and law enforcement system problems are the fundamental sticking point of food safety incidents." Du Wenyu said that the establishment of a sound regulatory standard and supervision mechanism is building the city wall. "We have to restore people's confidence in food safety." He said.
