Underwater objects: milk, animal feed.
Melamine is a low toxic chemical raw material. Due to the defects in the methods used to estimate the content of protein in China's food and feed industry, melamine is often doped into food or feed by unscrupulous businessmen to improve the protein content index in food or feed testing, so melamine is also called "protein essence" by counterfeiters.
The recent tainted milk powder incident has become famous all over the world, so I'm speechless here.
Just as I was sorting out this passage, another poisonous snake incident happened in Zhejiang. Preserved egg viper is a more terrible milk powder additive than melamine. Post it for everyone to see. The aftermath of melamine is not over, and similar incidents have happened again, which really makes people completely speechless. ......
Adding preserved egg viper to milk of a dairy enterprise in Zhejiang Province
Preserved Agkistrodon halys is a kind of egg with high chromium content, which is made of waste from tannery. At present, it is allowed to be used in animal feed industry in China, but due to "unreasonable feeding leads to chicken poisoning", the content of protein can be increased. Zhejiang Chen Yuan Dairy actively added it to dairy products.
On April 24th, 2009, Zhejiang Jinhua reported the investigation and handling of the case of "Chen Yuan Dairy Industry". Jinhua Chen Yuan Dairy Co., Ltd., located in Lanxi, Zhejiang Province, found a substance called "leather hydrolyzed egg viper" in many batches of milk, which is a suspected carcinogen.
Preserved egg viper
The main component of leather hydrolyzed powder is leather hydrolyzed protein, and the raw material of inferior hydrolyzed protein mainly comes from the corner waste of tannery. There are potassium dichromate and sodium dichromate in the waste of leather-making corners. Using this raw material to produce hydrolyzed protein, potassium dichromate and sodium dichromate are naturally brought into the product and absorbed by human body. These substances cannot be decomposed in the body, and will accumulate slowly, leading to poisoning, joint loosening and even child death.
According to food experts, the food added by leather hydrolysate is mainly milk, dairy products and milk-containing drinks, which can increase the content of protein. In other words, it is a substance similar to melamine, which is different from melamine in that the detection of leather hydrolysate is more difficult than melamine.
Consumer suggestion: It is best to buy all imported products. If there are no conditions, try to buy famous foreign brands (not completely guaranteed, at least relatively safe). Domestic brands, if they are not short of money, stay away. If they are short of money, I advise you not to drink.
Stay away from the so-called "high-end brand milk" with some special chemicals added.
Potential Listing 2: Formaldehyde
Underwater objects: aquatic products, alcohol, animal offal food.
Formaldehyde is a colorless, irritating gas, easily soluble in water, and its aqueous solution is commonly known as "formalin", which has antiseptic and fresh-keeping effects. Aquatic products soaked in formaldehyde are pale in color, tough in hand and hard in taste. If the amount of formaldehyde is too large, it will be irritating when chewing. Long-term consumption of food containing formaldehyde is harmful to human health.
Due to the lack of uniform packaging labels for aquatic products, illegal traders often add formaldehyde in order to increase water retention and extend the shelf life of aquatic products, regardless of consumer safety.
Formaldehyde whitebait: Soaking whitebait with formaldehyde can keep whitebait from rotting for several days, its color is unusually white and bright, its toughness is enhanced, and it is very popular. (picture)
Formaldehyde crab, formaldehyde clam meat
The inspection squadron of Wenzhou Industrial and Commercial Branch randomly sampled 33 batches of river crabs, all of which showed that the crab yolk of river crabs contained toxic chemical component formaldehyde.
The inspection brigade of Daliang Street, Shunde District, Foshan City focused on sampling semi-finished products and processed foods such as mussel meat, tripe, tripe and goose intestines, and took samples 1 1 at the scene, and immediately sent them to the food safety monitoring vehicle for rapid detection. Two samples of mussel meat, tripe 1 sample and tripe 1 sample were found to be unqualified, all of which contained formaldehyde preservatives.
Formaldehyde beer: adding formaldehyde is an open secret in the domestic beer industry. Why is there formaldehyde in beer? Because beer is an unstable colloidal solution, it is easy to produce turbidity and precipitation during production and storage, which affects the appearance of the product. If formaldehyde is added in the saccharification stage of beer production, it can not only inhibit the oxidation and dissolution of polyphenols in beer malt, make beer clear and bright, but also greatly shorten the time of wine production. The traditional beer brewing technology at home and abroad is to add formaldehyde in beer processing and production. China's "Hygienic Standard for the Use of Food Additives" also listed formaldehyde in the recommended list of processing AIDS in the food industry.
So formaldehyde is added as a stabilizer. Although the country has clear regulations on the content of formaldehyde in beer, it is only the lowest safety line, not completely harmless. Considering the cost, small and medium-sized breweries will not brew without adding formaldehyde. It is unknown whether small and medium-sized breweries will reduce the formaldehyde content in a responsible attitude towards public health.
After all, formaldehyde is a toxic substance. From the point of view of food safety, it is best not to add it. At present, some responsible well-known brand beer producers have given up the process of adding formaldehyde in beer brewing. Although the formaldehyde content of most beer products meets the national standards, it is not necessarily appropriate to make an analogy: the contents of heavy metals and chlorine in tap water generally will not exceed the national standards, but if conditions permit, we should be alert to the harm of toxic substances such as heavy metals in tap water and drink less tap water-we also suggest that you choose beer brewed by well-known brands without formaldehyde.
Consumer suggestions:
1, eat less animal offal food.
2. When buying water-based food, don't just look at the appearance of the food, but carefully distinguish it. Protein, a kind of food soaked in water soaked in formaldehyde, solidified, so it became tough, elastic and not easy to break. It smelled a little soaked in water and its surface was crystal clear.
Don't drink beer that is not sure and not well known. Try to buy brand beer marked formaldehyde-free.
Potential Listing 3: Bromate Pesticide Residues
Underwater objects: drinking water, fruits and vegetables.
Natural water is unnatural;
In China, especially in economically developed urban areas, with the serious pollution of rivers and lakes, a large number of industrial wastewater, domestic sewage and pesticides enter the municipal water system, and the existing urban sewage treatment system is difficult to meet the requirements of drinking water for residents. If you have the heart, study the urban water standards in China, and I believe you will make amazing discoveries. So when you blindly believe in "natural water", have you ever thought about the harm of air pollution, animal carcasses, pesticide residues and industrial wastewater pollution behind natural water?
Disinfection of mineral water and ozone;
Bromate, a term unknown to consumers but well known to the drinking water industry, began to surface with the formal implementation of the Hygienic Standard for Drinking Water (1) in July 2007 and the country began to solicit opinions on the new standard of mineral water last year.
Because the national drinking water standard has very strict requirements on the total number of colonies, which is limited to 50cfu/ml, bromate will inevitably be produced by various manufacturers in the sterilization process, and bromate, an inorganic disinfection by-product produced by ozone disinfection of drinking water, is a potential carcinogen rated as Grade 2b by the International Agency for Research on Cancer.
Fruits, vegetables and pesticide residues:
According to the investigation of agricultural plant protection department, according to the survey statistics of five main vegetable types by households, 32.8% growers used highly toxic pesticides on leafy vegetables. The main vegetable varieties are tomatoes, cucumbers, peppers and beans. The main drugs are omethoate, parathion, phorate, methamidophos, isocarbophos and carbofuran. Methamidophos is the most commonly used pesticide with high toxicity and broad spectrum. Methamidophos is often used secretly by vegetable farmers because of its large yield, low price and good efficacy. The frequency of use in leafy vegetables is as high as 50-60%, and the frequency of use of parathion in tomatoes, beans and peppers is as high as 60%. More importantly, the survey shows that drugs are generally used within 10- 15 days before harvest. Some people even take medicine four days before harvest. The high concentration of pesticide residues on vegetables affects the health of consumers.
Consumer suggestions:
1. Don't be superstitious about the so-called "minerals" of natural water or mineral water. The function of drinking water is to quench thirst. Whether it is pure water, mineral water or natural "mineral" water, you should read the product label carefully and choose a good brand. Don't believe those endless concepts: in fact, mineral water from tap water and "weakly alkaline" water advertised as alkaline in PH are just marketing gimmicks.
2. Drink little or no city tap water.
3. Get into the habit of soaking vegetables in alkaline water or rice washing water, which can remove some pesticide residues.
Potential Listing 4: Clenbuterol
Underwater object: pig
Clenbuterol is an animal medicine. There are several drugs called Clenbuterol, such as ractopamine and Clenbuterol. Adding lean meat to feed can increase the amount of lean meat in animals, reduce the consumption of feed, bring meat to the market in advance and reduce the cost. However, due to the side effects on human body, the standards for open use vary from country to country. Clenbuterol belongs to Class B accelerant, which can promote the synthesis of protein, make pigs grow more lean meat (lean meat) and less fat, and can be added to pig feed for long-term consumption. The pigs are in good shape and have high profits. Farmers can mix lean meat with pig feed to feed pigs, which can make pork grow lean meat quickly.
Clenbuterol pork
After pigs eat lean meat, lean meat is mainly stored in pig liver, pig lungs and other places. If you don't use it according to the regulations, the residue will be too high, and after eating a lot of pig liver and pig lungs, even cooked food, you will immediately have poisoning symptoms such as nausea, dizziness, muscle trembling, palpitation and elevated blood pressure.
Consumer suggestions:
1. Generally, pork with lean meat is unusually bright in color;
2. Pork cut into two or three fingers wide is soft and cannot stand on the chopping board;
3. There is yellow liquid flowing out between lean meat and fat;
4. Observe the fat layer of pork. If its thickness is less than 1 cm, there is a problem. Generally, the fat layer of pork is more than 2 cm.
Potential List 5: Sudan Red
Underwater objects: peppers, eggs.
Sudan red is a lipophilic azo compound, which mainly includes four types of Sudan I(SudanI): I, II, III and IV. "Sudan Red" is not a food additive, but a chemical stain. Its chemical composition contains a compound called naphthalene with azo structure. Due to the nature of this chemical structure, it is carcinogenic and has obvious toxic effects on liver and kidney organs of human body. Sudan red is a chemical dye, which is mainly used in industrial solvents such as petroleum and engine oil to brighten it, and also used to brighten shoes and floors.
Why is "Sudan Red" spicy?
An industry insider analyzed that Sudan red, as a chemical raw material, was added to food, especially in the processing of pepper products. First of all, Sudan red is not easy to fade after use, which can make up for the discoloration of pepper after long-term storage and maintain its bright color. Second, some enterprises dye corn and other plant powders with Sudan red and mix them with Chili powder to reduce costs and gain profits.
Red heart egg
In June, 2006165438+1October, 65438+June, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) found that Sudan Red was detected in the nominal Shen Dan egg products. Natural breeding can't feed "red heart" eggs, so experts think it is probably related to feed additives. Whether it's duck eggs or eggs, if the yolk is too black, it may be added with something, even if it's not Sudan red, it may be other pigments. "Sudan red" was detected in eggs and duck eggs, and the most likely reason was that problematic additives were added to the feed for raising chickens and ducks. According to experts, according to the traditional natural feeding method, chickens and ducks can't feed "red heart" eggs no matter how many bugs they feed.
Consumer suggestion: Experts remind readers that no matter whether they buy duck eggs or free-range eggs, they should not choose bright red yolk, because it is likely to be poisonous eggs; In addition, readers should be vigilant and buy egg products to see the production date and shelf life of the goods.
Potential List 6: Food Additives
Underwater objects: drinks, snacks and some movable foods.
Looking around all kinds of foods around us, additives appear on the packaging labels of almost any food. These food additives, all chemical products, all have hidden dangers in one way or another. Take the wide variety of fruit juice drinks on the market. Is it juice or drink? The relationship between juice drinks and juice is actually like the relationship between milk drinks and milk. Milk drink is not milk, and fruit juice drink is not fruit juice. Imagine that an apple can be made into a four-piece juice drink and a watermelon can be made into a twenty-piece juice drink! In fact, an apple squeezed out less than half a cup of juice, and half a cup became four sticks. What's in it? The answer is: food additives.
Preservatives, such as low sodium oxide or low potassium oxide, are usually added to beverages to ensure a long shelf life. What's more, some juice drinks are directly mixed with essence and water. There are dozens of varieties such as pineapple, banana, peach, Sunkist orange, apple and grape, as well as yogurt essence and fresh milk essence. According to the ratio of 1: 100 to 2: 100, water and sugar can be added to make various flavors. " It is necessary to add some thickener when preparing milk. The packaging of these food additives is mostly around 500 grams, and the price ranges from several yuan to several tens of yuan. It is very cheap to make food and drinks with them.
Award-winning question and answer: Is there a pineapple in the once popular "pineapple beer"?
Consumer suggestions:
If you want to supplement vitamins by drinking fruit juice, it is recommended to eat fruits and vegetables directly, or look for pure natural fruit and vegetable drinks. If you want to quench your thirst, try to drink boiled water. Of course, some big brands of drinks have strict scientific testing and artistic craftsmanship, and the quality is more guaranteed. It is ok to drink them in moderation.
Potential List 7: Sodium Bicarbonate and Mineral Oil
Submerged object: Chen Huami
The chemical name of sodium formaldehyde sulfoxylate is sodium formaldehyde sulfoxylate, which is easily soluble in water and can be decomposed into formaldehyde and sulfur dioxide when it meets acid or alkali at a slightly higher temperature. It is an industrial bleaching agent that is forbidden to be used in food, mainly used in printing and dyeing industry. The state explicitly prohibits the use of sodium formaldehyde sulfoxylate in grain products, but many operators illegally add sodium formaldehyde sulfoxylate by taking advantage of its characteristics of bleaching, coloring, antisepsis and improving the toughness of flour products. After people eat food with sodium bicarbonate, it will cause poisoning, allergy and intestinal irritation, and people will die if they ingest 10g.
