Melamine was first used in livestock feed production by counterfeiters in China and added to feed. As soon as the instrument is tested, there are a lot of nitrogen atoms. In this way, the content of protein is also high, and producers naturally save the expensive protein powder. Although melamine is toxic, cattle and sheep are relatively large in size and have strong renal function, so they can metabolize toxins smoothly. After eating it, nothing seems to happen, so no one cares. The counterfeiters naturally expanded the scope of application, and by the way, melamine was used in pet feed exported to the United States. Unfortunately, pets such as cats and dogs are much smaller than cattle and sheep, and their metabolic ability is poor, so the toxic effect of melamine is also great. As a result, cats and dogs were poisoned, and foreign grandfathers in the United States were alarmed. Finally, melamine has also entered the sight of the US FDA. It is said that Americans were puzzled when they found melamine. They don't know why they added it, thinking it was caused by rat poison pollution. I remember that the American news media reported that it was suspected that the grain warehouse in China was not well guarded, which caused rat poison pollution. Finally, an informed China couldn't help secretly telling Americans the secret of adding melamine to this food. This makes the American academic community gathered with this expert suddenly realize that this is a complicated high-tech fraud process. Attention, this Sanlu milk powder incident has been "polluted" by the cheapest 18 yuan bag of baby milk powder (at present, a bag of 400g milk powder for adults in supermarkets costs about 20 yuan, and the price of baby milk powder is arguably at least doubled). Obviously, Sanlu has adopted a low-price dumping strategy, occupying the last piece of fat in the rural milk powder market, but it is not enough to sell this 18 yuan bag of milk powder. So in order to save costs, Sanlu added cheap soybean protein powder to milk powder instead of milk powder. This soybean protein powder was not a big deal, but it was this time that melamine, a high-tech gadget forged in protein, was added, which finally created the sensational Sanlu milk powder incident. Of course, this high-tech gadget must be added to adult milk powder, because the metabolic ability of adults is much stronger than that of babies, and there will naturally be no poisoning incidents except for special patients. In addition, if you want to know the extensive application of melamine in China's food industry and feed industry, Google "Albumin" to see the results. In fact, there are more advanced counterfeit products than melamine, which can be "washable and testable" and "resistant to ammonia nitrogen reaction". In short, your high-tech grandfather can't detect that this is fake protein. Sanlu milk powder incident reflects the seriousness of food safety problems in China from one aspect (in fact, Fonterra actually holds 43% of Sanlu milk powder shares). What is left for us to eat safely now? Melamine, the black hand, spread from the initial cattle and sheep feed market to today, and finally reached the field of baby milk powder. I think hundreds of millions of people in China, unconsciously, have been eating pork, beef and chicken fed with melamine for many years, and drinking adult milk powder with melamine for many years, and unconsciously, they are all contaminated by melamine. Has anyone done the long-term effects of melamine on human health? I don't think so, because no one would have thought that hundreds of millions of people in a country would eat this plastic industrial raw material that has nothing to do with food.
