What are the fluorescent dyes in the bisoxalate-hydrogen peroxide-fluorescent dye fluorescence system?

Clenbuterol hydrochloride is an animal medicine. There are several drugs called Clenbuterol, such as ractopamine and Clenbuterol hydrochloride. Adding clenbuterol to feed can increase the number of lean-meat animals, reduce the consumption of feed, make meat market earlier and reduce the cost. But it has a very dangerous side effect, from arrhythmia to heart disease, which may lead to serious problems.

2. Milk mixed with melamine and its products

Commonly known as melamine, albumin and melamine, it is a triazine nitrogen-containing heterocyclic compound used as a chemical raw material. Because it is harmful, it cannot be used in food processing or food additives. Intake of melamine may cause long-term damage to animal's reproductive and urinary system, bladder and kidney calculi, and may further induce bladder cancer. However, some unscrupulous merchants often mix melamine into food or feed in order to improve the protein content index in food or feed testing. In recent years, melamine has been repeatedly found in milk and its products in some places. Especially in the "Sanlu milk powder" incident that broke out in September 2008, according to the Ministry of Health, as of 8: 00 a.m. on September 2, 2008, a total of 2,892 infants 12892 were reported to have been hospitalized for eating infant formula, among which 4 infants 104 with severe symptoms were cured and discharged.

3. Fruits and vegetables ripened with ethephon ripening agent.

Ethephon is an organic compound, which is usually used to stimulate crop growth, but it is harmful to health. Normal and mature fruits should be rich in nutrition and sweet in taste. Ripening fruits with plant growth regulators can change the surface color of fruits, but the internal quality of fruits has not changed, and fruits should be rich in nutrition. In order to get a good price and go public in advance, some merchants often use ethephon as a ripening agent to ripen immature bananas, tomatoes, watermelons and other fruits and vegetables quickly. Eating fruits and vegetables ripened by ethephon is harmful to human body.

4. Washing powder fritters

Some manufacturers make fried dough sticks and detergent to make fried dough sticks gray flour. The fried dough sticks are so bright and beautiful, and they are very eye-catching. Detergent sulfonic acid, with moderate toxicity, is the main component entering the human body, which can inhibit the activities of pepsin and trypsin, thus affecting gastrointestinal function, but it also damages liver cells, leading to liver dysfunction, diarrhea, indigestion, kidney abnormality in liver area, spleen atrophy and even cancer, leading to blood system diseases.

5. Antibiotics for fish farming

At present, fish farmers in China provide fish disease prevention, adding nitrofurans to fish feed, and antibiotics such as chloramphenicol and ciprofloxacin are common. Antibiotic residues in aquatic food chain are enriched for a long time. When the human body ingests some drugs and food residues for a long time, it may lead to the accumulation of drugs in the body and eventually lead to toxic damage. For example, chloramphenicol can inhibit the hematopoietic function of bone marrow and cause aplastic anemia and agranulocytosis.

6. Feed the ducks to Sudan

Some duck farmers let ducks lay red-hearted duck eggs, and duck feed is in Sudan. Sudan red is a chemical dye, not a food additive. Accord to that risk assessment report of Sudan red issued by the ministry of health, Sudan red will increase the risk of canc if food containing high doses is consumed frequently, so it should be ban.

7. Pesticide residues

Pesticide residue in agricultural products refers to the application of pesticides in agricultural production. The latter directly or indirectly affects pesticide residues in grain, vegetables and fruits, livestock products, aquatic products, soil and water. In China, the problem of pesticide residues in agricultural products is quite common. Food contains a large number of highly toxic, highly toxic and highly residual pesticides, which can lead to acute poisoning of people and animals. Long-term consumption of agricultural products with excessive pesticide residues may not lead to acute poisoning, but may lead to chronic poisoning of people and animals, thus leading to the occurrence of diseases and even affecting the next generation.

8. Feed livestock and fish hormones

In recent years, in order to pursue high profits, some farmers have increased the concentration of livestock, poultry, fish and shrimp, abused hormones or used hormones at will. Long-term consumption of foods containing hormones may lead to weight gain, osteoporosis, decreased resistance, increased blood sugar, corticosteroid diseases, digestive tract ulcers, electrolyte disorders and so on. And it also affects children's development.

9. Artificial eggs

In recent years, there have been some underground factories producing artificial eggs in the market, which, as the name implies, use other raw materials. Artificial eggs and real eggshells are mainly composed of calcium carbonate, and also contain a small amount of artificial egg gypsum. In egg white, yolk and really different ingredients, the main ingredients of synthetic resin are eggs, starch, coagulants, pigments and other chemicals, pigments and resin yolk. Studies have found that long-term consumption of artificial eggs can cause brain memory loss and dementia.

10, poisonous bean sprouts

In 2009, "poisonous bean sprouts" were found in Changchun, Lanzhou, Zhengzhou and Shenyang. Poisonous bean sprouts, which seem to be more than 10 cm long, some are nearly 20 cm long, with even heads and white colors. Most of them have no roots and look beautiful. According to the regulations, no additives are allowed in the production of bean sprouts, but in order to make more money, black processing points are needed. During the production of bean sprouts, at least four additives, urea, enrofloxacin and 6- benzyladenine, exceeded the standard seriously. Urea and 6- benzyladenine bean sprouts grow thick and long, which can shorten the production cycle and increase soybean germination. However, people will produce nitrite after ingestion, which will cause cancer after long-term consumption.

1 1, using industrial alcoholism

It is often found that some unscrupulous merchants use industrial alcohol to consume wine to make money in recent years. Wine is brewed by eating agricultural products such as grains. The main chemical component of wine is ethanol, and mixed alcohol generally contains a small amount of esters. The consumption of wine is 60 degrees (60%) or less. Although the main chemical component of industrial alcohol is ethanol, it contains a small amount of methanol. Methanol is very toxic, which has the greatest influence on the nervous system and blood system of human body. Symptoms of acute poisoning include: headache, nausea, stomachache, fatigue, blurred vision, even blindness, and then difficulty breathing, which eventually leads to respiratory paralysis and death. Chronic toxic reactions: dizziness, drowsiness, headache, tinnitus, fatigue and digestive system disorder. If the intake of methanol exceeds 4g, poisoning reaction will occur; If the intake of methanol exceeds 10g, it will lead to blindness, and if it is drunk, it will lead to death, resulting in a dose exceeding 30ml. Methanol is not easy to be discharged in the body, and it accumulates and oxidizes in the body. Formaldehyde and formic acid are also toxic.

12, posing as industrial salt and table salt.

Daily salt is defined as the extraction process of sea, salt lake, salt and salt. Its main component is sodium chloride, commonly known as sea salt, lake salt, well salt and rock salt. "Industrial salt" refers to a compound composed of metal ions (including ammonium ions) and ions, which has a wide range of different properties, different appearances and different uses. Many "industrial salts" are toxic and harmful. Due to the high profit of salt, in recent years, some lawless elements pretend to be industrial salt for sale.

13, smoked ginger with sulfur

In recent years, sulfur-smoked ginger has been found in many places in China for sale. Some unscrupulous traders smoke toxic chemicals soaked in water with sulfur. Compared with normal ginger, smoked "poisonous ginger" looks more tender and Huang Liang in color, just like it was just picked. Sulfur is a metal sulfide. If ingested in food, it will cause mild dizziness, dizziness, listlessness, general fatigue and other symptoms. If eaten for a long time, it will seriously affect people's liver and kidney function. What is even more worrying is that these vendors fumigate unsolicited ginger, which may contain impurities and heavy metals, posing a threat to health, and more seriously. If you eat this kind of food often, you are undoubtedly taking chronic poison.

14, wash crabs with oxalic acid.

Oxalic acid plays an important role in industry. Oxalic acid is harmful to the pH value of human body, leading to imbalance, and overeating can cause poisoning and stones. Oxalic acid will affect children's development. If oxalic acid changes calcium and zinc into calcium oxalate and oxalic acid in human body, it will be easily absorbed and excreted by human body, which will affect the absorption of calcium and zinc. Children need a lot of calcium and zinc for their growth and development. If the body lacks calcium and zinc, it will not only lead to bone and tooth dysplasia, but also affect intellectual development. Rust-proof bleach commonly used in oxalic acid industry. In recent years, it is very common to resell crabs washed with oxalic acid, because after all, crayfish washed with oxalic acid (commonly known as "shrimp washing powder") are very bright in color, and it is difficult to distinguish real crabs from crabs washed with oxalic acid (commonly known as "crab washing").

15, soaked in formalin

Shrimp, whitebait, Maoxuewang, tripe, bezoar throat, chicken feet, jellyfish, some hot pot restaurant fans, and some foods on the market at present have been soaked in formalin. Because the processed food is not only shiny, but also absorbs a lot of water, the weight increases significantly, such as shrimp soaked in formalin, which can increase by 10%. Formaldehyde aqueous solution, also known as formalin, contains 35% to 40% formaldehyde (usually 37%). Medical experts believe that it is a chronic poisoning drug. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, menstrual disorder in women, neonatal physique or nasopharyngeal symptoms, and toxic effects of high-concentration formalin on nervous system, immune system and liver.

16, used for processing caustic soda in food industry.

Also known as caustic soda and caustic soda, the chemical name is sodium hydroxide. Caustic soda can be used in food processing, but it must be food-grade caustic soda. Because food grade contains toxic substances within the control range, the content of toxic and harmful substances is high, so it can not be used in food production in the industrialization stage. However, the price gap between food-grade caustic soda and industrial-grade caustic soda is relatively large. At present, the market price of industrial caustic soda is more than 3,000 yuan per ton, while the price of food-grade caustic soda is more than 6,000 yuan per ton. Some small workshop-style manufacturers and unscrupulous traders, desperate for profits, use industrial-grade caustic soda in food processing instead of food-grade caustic soda. People find it useful to soak tofu and cakes, shrimp and tripe, boiled peanuts, etc. with industrial caustic soda.

17, the fish was polluted by malachite green.

Malachite green is a toxic triphenylmethane synthetic organic compound, and two dyes and fungicides can also cause cancer. Malachite green has been widely used to control fungi, molds and melon diseases of various aquatic animals. Since 1990s, scholars have found that malachite green and its metabolites are highly toxic, highly residual, highly carcinogenic, teratogenic and mutagenic. In view of malachite green, malachite green is dangerous because many countries will ban drugs in aquaculture. In May 2002, China also banned malachite green from all food animals. However, malachite green is still widely used by some farmers and fishmongers in the production and transportation of aquatic products because of its low price and remarkable bactericidal effect.

18 days

Gutter oil refers to all kinds of oils in life, which can be divided into three categories: first, gutter oil in a narrow sense, that is, oily floating objects in sewers or leftovers from hotels and restaurants (commonly known as swill) are simply processed and refined; Second, the output of inferior pork, pig offal, pig processing and refined oil; Thirdly, the fried food is used for more than a certain number of times, and then it is reused, or some new oil and regenerated oil are added. Waste edible oil is harmful to human body, and long-term consumption may cause cancer. According to some experts' estimation, when the country that has been "gutter oil" for one year returns, oil accounts for 10% of the total. In March 20 10, the General Office of the State Food and Drug Administration of the United States issued the Emergency Notice on Preventing Waste Oil from Entering Catering Services, and in July 20 10, the State Council issued a decision to organize the pilot work of recycling kitchen waste and harmless treatment of urban waste oil. However, the economic temptation is not small, and there are still unscrupulous vendors who take risks to sell and use waste oil.

19, dyed steamed bread and corn steamed bread

Recently, many dyed steamed bread and corn bread have been found. Corn bread, corn bread, some illegal enterprises use lemon yellow. Also known as tartar yellow, lemon yellow, acid yellow, hydrazine yellow and lemon yellow, it is a synthetic pigment, and its national scope has strict regulations, so it should not be used in bread. General toxicity and diarrhea, such as eating a large amount of pigment at one time, may cause allergies, diarrhea and other symptoms, and long-term consumption will lead to harm to human body, such as liver.

20. Bleach steamed bread, noodles and other flour products with toxic and harmful methods.

On 20 11March1day, the Ministry of Health and the Ministry of Finance issued an announcement, and flour brighteners were banned from May 1 1 day. The active ingredient is benzoyl peroxide, which is a flour whitening agent and a commonly used flour food additive abroad since the late 1980s. Mainly used for bleaching flour whitening agent and accelerating after-ripening of flour. Due to the negative effects of flour brighteners, the relevant state departments decided to ban benzoyl peroxide and calcium peroxide in flour production and food additives after repeated research. It is expected that all contracting parties will ban flour brighteners, and the use of toxic and harmful methods to bleach steamed bread, noodles and other flour products may breed. Common toxic bleached steamed bread, noodles and other flour products, its method is:

First, use a hanging white block. The chemical name of formaldehyde is sodium formaldehyde sulfoxylate or sodium formaldehyde sulfoxylate, which has a strong reducing and bleaching effect at high temperature. Formaldehyde is used as discharge agent and reducing agent in printing industry, and there are some organic bleaching and bleaching. In addition to flour products, formaldehyde is also used in food processing by many illegal traders.

Twice sulfur fumigation with white bread. Bleaching effect of sulfur dioxide and high temperature steam titanium oxide.

Pasta made of tricolor powder. Fluorescent agent, also known as optical whitening agent or fluorescent bleaching agent, is used as an auxiliary class in China. The whitening effect can't be seen at first when the fluorescent powder is added to the flour, but it will be particularly obvious after the first steam is changed into steam. After being absorbed by the human body, the fluorescent agent will accumulate in the human body, greatly weakening the immune system. For example, overexposure can accumulate toxicity in the liver or other important organs, leading to cancer.

Food made of flour and sodium chlorite. Sodium chlorite, white powder, odorless or slightly odorless, nontoxic. As a bleaching agent, it is mainly used to bleach textile fibers and paper pulp, and also used for metal surface treatment, water purification and sewage treatment of leather wool. Adding sodium chlorite to flour can steam out big, white and bright steamed bread, as well as restaurants and pressed bleached pasta noodles.

The above bleached bread, noodles and other flour products are harmful to human body, but they are also prohibited in food processing.

2 1, tender meat powder with excessive nitrite.

In recent years, many restaurants, supermarkets and shops have improved the taste of meat, beef and pork and supplemented tender meat. The basic component of tenderloin is papain, which decomposes protein, such as enzymes, and is used to dilute and fill starch. In order to improve the "efficacy" of tender meat powder, many components of tender meat powder have been reformed, and chemicals such as phosphate and sodium carbonate have been added. In order to help dye hair, prevent corrosion and flavor, some also added nitrite. In 2009, nitrite was found in China Agricultural University Laboratory 10 kinds of tender meat powder and cured meat substances, but only two kinds of packaging labels were found. 10 the nitrite content of all kinds of tender meat powder and cured meat compounds is in some limited national standards, while others are more than five or six times or even more. In recent years, the catering system has occupied a considerable share in the nitrite poisoning incidents notified by the health department. At present, the meat products being processed will be allowed to use nitrite as coloring agent, but the use amount is limited. But excessive consumption is harmful, and excessive consumption can cause food poisoning. Eat 0. 30.5 grams of nitrite can cause poisoning and even death.

22. Inferior soybean oil polished rice

In many places, almost all rice is polished before it goes on the market. Polishing can remove the surface of rice bran and make it have a good appearance, which is harmless to human body. However, it has become an unspoken rule for unscrupulous merchants to add soybean oil to polishing. Rice polished with inferior soybean oil is prone to rancidity, which will cause harm to organs such as stomach and intestines and affect bones. Even if some insidious businessmen use cheap and toxic industrial oil to polish rice, it will affect the digestive system and nervous system of the human body and endanger life.

23. Mix industrial bleaching powder with industrial bleaching powder.

In some places, this has become a habit. Some companies will mix 50kg flour with100g industrial bleach. Chlorine bleach is prepared by the reaction of calcium hydroxide (hydrated lime). Industrial bleaching stimulates gastrointestinal mucosal erosion, affecting liver, kidney and blood system. Eating bleach to bleach flour can cause food poisoning.

24. Dipdichlorvos soaked ham

Dichlorvos, also known as dichlorvos (scientific name O, O- dimethyl-O -O-(2 2,2-dichlorovinyl) phosphate), is an organophosphorus pesticide, which is toxic to people and animals and easily absorbed by the skin. Soak pork ham and legs with dichlorvos, because some unscrupulous manufacturers soak pork legs with dichlorvos, and flies won't stare, but they can look as good as fresh ham and keep for a long time.

25, poisonous cowpea

20 10 the investigation results in Wuhan, Shanghai, Guangdong, Chongqing, Jiangxi and other places come from the highly toxic pesticide isocarbophos, which is a highly toxic pesticide-forbidden fruit, tea, tobacco, vegetables and Chinese herbal medicine plants in Hainan. It causes human poisoning through esophagus, skin and respiratory tract.

On the 26th, add "a drop of incense" food.

"A drop of incense" is a food additive, but a drop of water can be turned into broth. Many hotels are using this "spice that can obviously improve the flavor", among which hot pot restaurants, Lamian Noodles shops and casserole rice noodles on the street are the most widely used. The so-called three fresh, spicy, spicy, all rely on "a drop of incense" to produce attractive fragrance effects. "China Quality News" once reported that food experts can basically conclude that "a drop of incense" is directly blended through chemical synthesis reaction, and its nutrition is very limited. Long-term consumption of "a drop of incense" will damage the liver and be harmful to health. The national industrial product production license inquiry agency also said that "a little incense" belongs to chemical products, which is very harmful to human body after eating. It may damage the liver, and it is also cancer.

27. Foods treated with hydrogen peroxide

Hydrogen peroxide, that is, hydrogen peroxide solution, a colorless and odorless liquid, is a strong oxidant, which can be added to food for bleaching, antisepsis and deodorization. Therefore, some businesses need some whitening foods, such as water, food tripe and jellyfish, sharks, shrimps, octopus, squid, canned fruit and flour. It is forbidden to soak in hydrogen peroxide in the production process to improve the appearance of products. Even moldy dry aquatic products in small food processing units are resold or eliminated from the surface of sick chickens, sick ducks or sick pork after being soaked in hydrogen peroxide bleaching process. These materials are soaked and bleached with high concentration hydrogen peroxide, and then artificial pigments or nitrite are added for sale. Hydrogen peroxide can form epoxide with starch in food and cause cancer, especially gastrointestinal cancer. In addition, industrial hydrogen peroxide contains toxic and harmful substances such as arsenic and heavy metals, which seriously harms consumers' health. FAO and the United Nations World Health Organization conducted toxicity tests according to the declaration requirements, and hydrogen peroxide was only used as an emergency measure for milk preservatives. China's "Hygienic Standard for the Use of Food Additives" also stipulates that the use of hydrogen peroxide in milk is limited, and there are only two kinds in Inner Mongolia and Heilongjiang, and residues are not allowed in other foods.

28, fake gelatin

In recent years, driven by interests, there are many small factories that produce fake and shoddy gelatin. In some small factories, the hides used in leather processing to produce Ejiao are basically cut off the nerves in the waste materials such as head and leg skins. These materials pretend to be pure donkey skin with edible gelatin, which seriously harms consumers' health.

29. Soy sauce production

A few years ago, many places found a way out in the market. Instead of brewing soy sauce with traditional techniques, soy sauce was used to prepare amino acid solutions, which was a dirty hair processing. The main component of soy sauce is amino acid. Using this amino acid solution to prepare soy sauce, soybean and other raw materials, not only has no soy sauce and nitrogen content that needs fermentation, but also can completely meet the national standards. However, this process and the amino acid solution of hair contain harmful substances such as arsenic and lead, which have toxic and side effects on human liver, kidney, blood system and reproductive system and can lead to cancer. Adding caramel sauce will produce harmful substances such as 4- methylimidazole, which can cause convulsions and even induce epilepsy patients. Therefore, the state prohibits the use of amino acid solutions produced by non-food raw materials such as hair to prepare soy sauce.

30. Fake chicken

In recent years, fake chickens have been found many times in various places. The price of fake chicken is surprisingly low, but the cooked food tastes a bit strange. Chicken is a kind of compound seasoning. Its basic component is monosodium glutamate, the content of which exceeds 90%. Based on the value-added treatment of refreshing agent, salt, sugar, chicken powder, spices and chicken flavor essence, it contains a variety of amino acids and other ingredients, which is harmless to human body. However, it contains fake chicken essence, pigment, industrial salt, and toxic and harmful substances, which is harmful to diet health.

3 1, poisonous seeds

In recent years, many kinds of viruses have been found in many places. Some underground black processing points make the seeds bright and completely smooth, and in this process, alum, industrial salt, paraffin wax and harmful substances in mineral oil industry are added. If consumers eat these seeds, it will harm their health.

32. Fake wine

20 10 February 2008,10, the Changli fake wine production enterprise exposed by CCTV, sold to Beijing at a low price. According to "China Wine Technical Specification" issued by China in 2003, wine must be fermented with 100% grape juice. These enterprises are wine blended with water, alcohol, pigment, tartaric acid, citric acid, sodium citrate, tannin and essence, but they don't make the necessary grape juice, which is a fake. Drinking this fake wine is harmful to human health. For example, blending fake wine with citric acid can promote the excretion and deposition of calcium in the body. For example, long-term consumption of foods containing citric acid may lead to hypocalcemia and increase the risk of duodenal cancer.

33, fake milk powder, fake milk powder

In recent years, fake and shoddy milk powder and other dairy products have been discovered in Zhejiang, Henan and other places. In Henan, some manufacturers will sell milk, and dairy products and drinks will be passed off, which is far less nutritious than pure milk. Long-term consumption will affect children's development. Part of the inferior starch in the black processing point is mixed with glucose powder, which is treated by a blender, then labeled with brand milk powder and packaged in exquisite packaging. If you use this fake milk powder, baby food, the result can be imagined.

34, pretending to be paraffin butter to make hot pot bottom packaging

Recently, it was found that some manufacturers in Chongqing and other places used paraffin wax as the bottom material of butter hot pot packaging. Under normal circumstances, the main raw material for making hot pot bottom material is butter, and butter will work harder when the weather is cold, so the reason why the bottom material is good is that butter becomes difficult. However, some manufacturers reduce the cost, without affecting the use experience, the amount of butter is reduced, and the cost of packaging paraffin is increased. The owner of a food factory in Chongqing said that one catty of wax can use four catties of butter, and its hardness can be three to four times or even five times that of butter. Edible wax is petroleum extract, which is mainly used in the production and use of containers and packaging materials in contact with food. It is strictly prohibited to be used as food additives. But in Chongqing, a ton of edible wax costs 8,000 yuan, and a ton of packaged paraffin costs only 5,000 yuan and NT$ 3,000, which is cheaper than edible wax. Therefore, some manufacturers use hot pot bottom materials to process cheap packaging paraffin. According to the relevant regulations of the health department, even edible wax is processed with non-composite hot pot, not to mention wax only used for packaging. Paraffin contains a variety of packaged organic compounds, which are carcinogenic to human body, and some substances accumulate in the body, leading to long-term chronic harm.

35, toxic black fungus

Auricularia auricula is a delicious food with high nutritional value. Due to the high price of auricularia auricula products, some enterprises in the market use it to obtain high-quality products and edible gum, and boil pigments to improve the color, texture and thickness of auricularia auricula slices and increase the weight of auricularia auricula itself. In fact, some unscrupulous traders are more insidious because fungus makes "articles" and turns people who eat food into "drugs". In order to keep the cost low, if there is any, the acquisition of high-quality edible fungus, Northeast Auricularia auricula, is more like being cut into the shape of Northeast Auricularia auricula by those who do not meet the specifications, and it needs to be colored with inferior ink to make it look black and shiny and better "sell". In order to increase the weight of auricularia auricula, some unscrupulous traders add white flour and powdered flour to auricularia auricula, and what's more, some add cement, copper sulfate and magnesium sulfate. These poisonous auricularia auricula do great harm to human health.

36. Bleached mushrooms

Let some unscrupulous merchants "sell" mushrooms, use fluorescent whitening agents, bleaching agents, bleached mushrooms and so on. 20101Media reported that the experimental report of Zhang Hao's seal face, a sixth-grade student in a primary school in Beijing, was based on mushrooms sold in the market, 90% of which were bleached. Eating bleached mushrooms in this way is harmful to human health.

37. Harmful preserved fruit

Some manufacturers preserved fruits, and microorganisms seriously exceeded the standard. Most bacteria exceed the standard 100 times. Some manufacturers also add harmful preservatives and excessive sodium cyclamate. These well-preserved fruits are harmful to human health.

38. Poisonous rice

In recent years, poisonous rice has been found many times in the market.
