Why should melamine be added to milk?

Because melamine and protein are both nitrogen-containing substances, this should be done to make fresh milk look high in protein during testing.

In the International Programme on Chemical Safety and the International Handbook on Chemical Safety (Volume III) edited by the European Commission, the description of melamine is: "Long-term or repeated exposure: the substance may affect the kidneys". Melamine is referred to as melamine for short, and its scientific name is melamine, also known as melamine, melamine and melamine. Melamine is an important nitrogen heterocyclic organic chemical raw material. This chemical is usually used to produce plastics, glue and flame retardants. Melamine contains nitrogen, which can increase the content of protein in feed products, and make the products appear higher in protein in routine inspection, thus improving the grade of feed. But melamine has no nutritional value. Melamine is a chemical that is forbidden to be used in pet food and animal feed. After animals eat it, it will lead to renal failure and death.

In fact, "melamine" has become a key word in the "pet food door" incident in 2007. In March 2007, pets died in the United States because of eating food containing toxic substances, which showed a rapid spread trend, and there were incidents in which pet food killed cats and dogs. According to incomplete statistics, in the United States and North America alone, tens of thousands of pets died suddenly because of eating toxic feed, and there are countless complaints. A survey by the US Food and Drug Administration showed that melamine was found in recycled pet food, urine crystals of dead animals and kidney cells, and it was confirmed that the raw materials of pet food were contaminated with melamine.

The recent tragic incident that milk powder was contaminated with melamine caused hundreds of children to get sick and one died, which made the call for compulsory detection of melamine in food more and more high. Ma Puni testing food testing experts said that melamine was not a routine testing item for foods such as milk powder before, but in view of the harm of this substance to human body, Ma Puni testing had carried out professional testing services for melamine before the "toxic pet food" incident in 2007, testing pet food, fish feed, baby food and its raw materials (including starch, rice protein, corn protein, gluten, etc.). ). PONY Pony test food testing experts suggest that food production enterprises should take the attitude of being responsible for product quality and send products to professional and authoritative testing institutions for testing related projects to ensure the health and safety of products and avoid the recurrence of the above tragic events.

Xinhuanet Beijing September 18 After the Sanlu infant milk powder incident, the CPC Central Committee and the State Council attached great importance to it and made major arrangements. In accordance with the requirements of comprehensive inspection of dairy products, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) urgently organized a national special inspection of melamine in liquid milk after completing the national special supervision and inspection of melamine in infant milk powder. The test results show that most liquid milk on the market is safe.

Special inspection According to the "three unifications" principle of unified inspection methods, unified inspection instruments and unified inspection result judgment rules, 150 national food quality inspection centers and laboratories were organized to supervise and inspect the national liquid milk production enterprises, and the inspection results were confirmed by the State Key Laboratory and the State Key Inspection Institutions.

This special inspection focused on whether the liquid milk produced by well-known brand enterprises such as Mengniu, Yili, Guangming, Sanyuan and Nestle with a market share of over 70% contains melamine. The test results are as follows:

Spot check Mengniu products 12 1 batch, no melamine was detected in10 batch, and melamine was detected in1/kloc-0 batch, with the detection value of 0.8-7 mg/kg;

8 1 batch of Yili products was randomly selected, and melamine was not detected in 74 batches, and melamine was detected in 7 batches, with the detection value of 0.7-8.4 mg/kg;

93 batches of Guangming products were randomly selected, and melamine was not detected in 87 batches, and melamine was detected in 6 batches, with the detection value of 0.6-8.6 mg/kg;

53 batches of ternary products were sampled, and no melamine was detected in 53 batches;

Seven batches of Nestle products were sampled, and no melamine was detected in seven batches.

No melamine was detected in 847 batches of liquid milk products produced by other 406 enterprises.

In order to make enterprises truly fulfill their social responsibilities, AQSIQ requires production enterprises to take the initiative to recall the batch of products with melamine detected. The products were removed from the shopping malls and the products without problems were sold normally. At the same time, for the rectification of production enterprises, starting with raw materials such as raw milk, batch inspection should be implemented, the quality and safety of production process should be strictly controlled, and batch inspection of ex-factory products should be strictly implemented. All products that have not been inspected or failed to pass the inspection are not allowed to leave the factory for sale, so as to effectively protect the health and safety of consumers. It is necessary to strictly investigate the reasons for adulterating melamine and severely punish those responsible.

According to medical experts, the United States Food and Drug Administration (FDA), the European Food Safety Agency (EFSA) and the authoritative organization of the health department in China have all made scientific assessments on the safe limit of human intake of melamine. According to the most stringent evaluation criteria, taking an adult with a standard weight of 60 kg as an example, it is safe to eat the liquid milk with the above melamine content if it does not exceed 2 liters per day (that is, 8 bags, 250 ml per bag).
