The ones that bleach bean sprouts " The sodium hydrosulfite " Can't be used in the vegetables
National regulation, " connect with two inferior sodium sulfic acid " Can not be used in the bean sprouts the bleaching of this kind of fresh vegetables. Staff reporter's king went on an expedition and took a photograph of it a few days ago, this newspaper reported " sodium hydrosulfite " in succession Bleach bean sprouts, industrial chemicals and whiten news such as the pig hoof, has caused the extensive concern of the society, furthermore let to bleach the food and become the focus which consumers paid close attention to recently. Which are there on earth to bleach food in our life? Are nutrition and security of bleaching the food still ensured? The current situation is bleached and used extensively in fact in the food industry, we have much food at one's side the process was bleached and dealt with, for example potato, lotus root, peanut, day lily, mushroom, steamed bun and some other color and luster lean towards light food. Bleach as a kind of industrialized means, the application in the food industry is very extensive too. When we are painted by the market agreeably, whitely if the food of the snow is attracted in winter, wonder it is so white why to think of the food? China Agricultural University the intersection of food and ZhiHong Fan, Professor of institute, say a lot of natural fruits and vegetables contain many phenol materials and oxidize enzyme among the food. When the notch of the food is exposed to air, much phenol, oxidase and oxygen meet, will happen brown and change and react. "This is a very normal thing, every white fruit vegetables, all have this kind of phenomenon mostly. It will influence the appearance when becoming brown after entering the supermarket, so the food is bleached just appears. " To bleach as to the food, it is only the iceberg corner that the vegetables melon and fruit mentioned above are bleached, it is numerous too that the other fields of food processing are applied to the situation bleached. National standard Even two inferior sodium sulfic acid can only be used in the dried food and nuts and bleach the black workshop of Fangshan district to use " The sodium hydrosulfite " Bleach the incident of the bean sprouts and let a lot of citizens in Beijing worry. The food security incident of our country takes place frequently, make a lot of citizens discuss " powder " in recent years The color changes, then this kind of " sodium hydrosulfite " What is it on earth? Researcher of food industry of Beijing research institute Li Gang says, " sodium hydrosulfite " Chemical name " Even two inferior sodium sulfic acid " ,It is a kind of bleaching agent often used industrially, can apply to the food industry too. A lot of consumers do not understand pollution has been heavier industrially why one kind of same chemicals can already be used such as textile, papermaking, can apply to the food industry. In fact regardless of what is in industry, the principle of bleaching this course is the same. Only different one is the food industry in consideration of personal security, will make higher requirement in quality, purity and applicable scope of raw materials, the interpolation not in accordance with these requirements belongs to adding illegally without exception. In " food additive uses standard GB 2760- 2011 " regulations to " connect with two inferior sodium sulfic acid " This kind of compound is a kind of additive that can be used in the food and bleach, mainly apply to dried food and nuts such as Guo doing, candied fruit, canned and bean vermicelli bean noodles. Can not use on this kind of fresh vegetables in the bean sprouts. So from the viewpoint of this, it is illegal that black workshop bleaches the bean sprouts with it. And it is industrial that what black workshop uses is connected with two inferior sodium sulfic acid, also not in accordance with regulation. Li Gang says, chemical raw materials that the small workshop is used for bleaching the bean sprouts are a kind of raw materials that can be used in the food industry at first, if the norm uses and has a little effect on health. But if bleach with raw materials not reaching the requirement of food industry, may receive the residual influence of heavy metal in raw materials, the situation that will suffer from abdominal pain, vomit when being serious. Inducement A certain material " It is said that carcinogenic" Overly the scientific tumour hospital of Chinese Academy of Medical Sciences gives protection against cancer Yuan FengLan, chief physician of department, says generally, cancer is a special disease of a kind of comparison, its morbidity range is wider, the canceration can take place both in several main organs and systems of the human body. And direct against different positions, the reason why cancer takes place is not the same. For example it is a great inducement of lung cancer to smoke, and bear an important inducement that is women's breast cancer late. So should get to a certain position specifically while mentioning the inducement of cancer. Yuan FengLan says, it is to smoke that the reason that can improve the whole incidence of all position cancers of body at present is clearer. Smoking is not only apt to cause lung cancer, but also will improve the emergence probability of cancer of the other positions. This is the result of setting up in a large amount of epidemiology research. And air pollution, pollution of waterhead factor these reason to bring out cancer too, which kind of material brought out cancer it can prove directly it is among them on earth but not studied yet at present, can only infer the it and relevance between cancer indirectly. Thus a certain statement that the material can be brought out such as cancer is not very scientific, can only be as a kind of general statement. The expert proposes to let" The primary color " The food returns to the dining table Wang Yi, bleaching agent of nutrition department director of food therapy of Guang'anmen hospital could contribute after needing to enter food, so bleaching agent may remain and enter the human body in the food finally. So consumer should try hard, select natural colored food, must guard against, buy the intersection of color and too pale food. For example the bean sprouts after bleaching can keep white and light color continuously, but the soya bean bud has thin brown if the ordinary bean sprouts have been generally reached at noon, one of the bean sprouts will begin to turn green too, wait until the color will be more ugly in afternoon. If go to buy the bean sprouts in the afternoon, it will be probably bleached if the color of the bean sprouts is very white. There is dry fruit like American pistachios, actually the outer cover should be slightly yellow. But some illegal retailers bleach the American pistachios with industrial hydrogen peroxide solution, seem to be clean and many, but disadvantageous to human body. Ginger, white fungus, rice, white sugar,etc. are the food often improved looks besides this. So consumers should try hard to select some primary color natural food when buying food, make illegally bleaching and losing the market, let the natural colored food get back to the dining table. It is actually a kind of very ordinary food that relevant to chain ammonia water and send the bean sprouts and bean sprouts harmful to human body, but become in recent years to let people hung back " The dangerous cargo " . Because bleach the many bean sprouts on one hand, on the other hand the bean sprouts sent with ammonia water have to be defended either. Wang Yi says, ammonia water can grow the plant and is beneficial to as a kind of nitrogen. Bank up with earth and take place the bean sprouts with ammonia water, though can promote the bean sprouts to grow, has brought the problem too. Because ammonia water have certain toxicity, light to make people shed tears, heavy to make people go into a coma. If contain 5�� ammonia in the air, will stimulate people's nose mucous membrane strongly, and cause indigestion, respiratory tract inflammation, can also make hearing fail, congestion inflammation of eyes. Because is growth period of bean sprouts is relatively short, when ripe, there is remaining ammonia in water. They will generate a bad impact on human body, and often make the bean sprouts present pained bad smell, have influenced the original tender taste of the bean sprouts. At present, still fail to determine correctly that trains the security density of the bean sprouts with ammonia water, and some people, in order to enable It is the shorter to contract in growth period of bean sprouts, the density of ammonia water added is larger and larger, this increases danger, so, should not stimulate the growth of the bean sprouts with ammonia water at will.
