Many mothers ask me what kind of milk their children should drink. I will recommend several brands to mothers, but mothers tend to choose imported ones. Most mothers will mention that they are afraid of giving milk. My child bought milk powder with a similar melamine problem!
Indeed, the 2008 "Sanlu Melamine Incident" affected 300,000 children! Many children have suffered damage to their kidneys, leading to problems such as kidney stones.
Because melamine will be excreted through the kidneys, it can cause damage to the reproductive and urinary system, bladder and kidney stones!
I still remember that in 2008, the hospital’s B-ultrasound room collapsed because children who had drank Sanlu milk powder could be examined for free to see if there were any stones in their bodies.
Why is there melamine in milk powder?
01
Later investigation found that it was mainly because the country had requirements for raw milk collection standards.
In 2008, the hygienic standard for fresh milk was GB 19301-2007. The protein requirement of at that time was at least 2.95 grams of protein per 100 grams.
Because most of the raw materials used in Sanlu milk powder at that time were fresh milk purchased from dairy farmers. For some fresh milk, the protein content did not reach 2.95 grams/100 ml. What should I do with ?
In order to avoid national detection, they added melamine in it.
The protein content in food is mainly estimated by simulating the nitrogen gas emitted by the human body after digestion. Only nitrogen gas is emitted after protein digestion in food.
After unscrupulous merchants add melamine, nitrogen can be excreted after the human body digests it, which infers that the protein content has increased.
This is the purpose of adding melamine to milk, just to falsely increase the protein content to meet national standards.

Later, during an investigation, a reporter found that children in many places in Shaanxi had kidney disease, and these children had drank Sanlu milk powder, and finally issued a report.
Finally, it was discovered that melamine was added to Sanlu milk powder. Later, it was also discovered that not only melamine was added to milk powder, but also some normal-temperature pure milk. led to a sharp decline in the trust of Chinese people in domestic milk powder!
Because of this, Tian Wenhua, the chairman of Sanlu milk powder, was sentenced to life imprisonment.
When the country updated the raw milk standards, it also lowered the protein content. The GB 19301-2010 raw milk protein standard is no less than 2.8 grams per 100 grams.
14 years have passed. Tian Wenhua, chairman of Sanlu Milk Powder, actively reformed in prison and successfully obtained three commutations. It is said that he may be released from prison in 2022.
Even Tian Wenhua, who was sentenced to life imprisonment, is ready to be released from prison, so time is the best medicine!
Coupled with the country's increasingly strict control over food safety, slowly we have regained confidence in domestic milk.
Coupled with the impact of the epidemic, the new coronavirus may contaminate food through the surface of food. For various reasons, the sales of domestic milk powder and domestic pure milk have begun to increase!

Unexpectedly, some time ago, the Market Supervision Bureau of Qingyuan County, Zhejiang Province, during a food sampling inspection on May 26, 2022, found that two batches of pure milk produced by Maiquer Group Co., Ltd. contained propylene glycol.
In the national standards for milk, propylene glycol is an additive that is not allowed! After the
test result was announced in June, it aroused the anger of the people!
You must know that after finally gaining some trust in domestic milk, another food safety incident happened!
Although propylene glycol, as a food additive, is allowed to be used in wet pasta and pastries.
But the only ingredient of pure milk is raw milk, and cannot add any additives!
And some experts have discovered that propylene glycol is also excreted through the kidneys, but 55% of propylene glycol cannot be metabolized and will turn into lactic acid in the body. If lactic acid accumulates in large amounts, it will also affect the kidneys and nervous system!
The propylene glycol content in the two pure milks sampled this time was not high, and it was far from toxic levels. Fortunately, it was discovered early!
Why is there propylene glycol in pure milk?
- Milk feed contains propylene glycol
because propylene glycol can prevent and treat dairy cow ketosis, and can also improve the cow's disease resistance and increase milk production. Therefore, many feeds actually contain propylene glycol.
It is possible that the residual propylene glycol in the cows has contaminated the milk.
When disinfecting cows, they were not washed thoroughly. The disinfectant contained propylene glycol.
Generally, the udders of cows are disinfected before milking, and some disinfectants add propylene glycol. The propylene glycol in these disinfectants will contaminate the milk.
- As a flavor, fragrance is added
Propylene glycol as a water-soluble flavor, fragrance, may be added to milk.
I think of the online reviews about Maiqule. It tastes very good and fragrant. So it is most likely added as flavors and fragrances.
"A glass of milk strengthens a nation" has been promoted for many years. Milk is a food containing high-quality protein and calcium, but when will we be able to drink "safe milk"?
