After preliminary investigation and analysis, the detection of propylene glycol was detected in the pure milk of the company.

On July 3rd, the official WeChat public account of the "Mc omine Dairy" said that according to the company's preliminary investigation, the unqualified product was failed to effectively clean the product tank line during the production and switching of two categories of pure milk and milk. The residual modulation milk causes the legal food additives (including propylene glycol components) in the modulation milk mixed with pure milk.

On July 4th, McElr apologized again that the company had stopped the production of pure milk, removed, sealed, and recalled unqualified products; it promised to return and refund unconditionally for consumers who had purchased unqualified pure milk.

What is propylene glycol?

According to the national "Food additive use standards", propylene glycol is a food additive approved by approved, and it is also a solvents allowed to use in food synthetic spices and food fragrances allowed to be used. However, propylene glycol must not be used in pure milk. ①

PhD in Beijing University of Chemical Technology and Chu Yuhao, an engineer of Sinopec Beijing Chemical Research Institute, introduced in the science popularization Chinese journal on July 2 that propylene glycol has a wide range of uses in industry and life. ②

It is widely used as a solvent in the chemical industry;

In cosmetics, soap and toothpaste, propylene glycol is often used as a wetting agent, moisturizing agent and antifreeze;

There are also certain applications in the field of resin synthesis and pharmaceuticals.

For additives in food, the national standards stipulate that propylene glycol can be used as a synthetic spice in food. The main function is stabilizer, coagulants, antidents, anti -foaming agents, emulsifiers, moisture holders and thickeners.

However, the national standard also stipulates that the use range of propylene glycol is limited to humid noodle products (noodles, dumplings, ravioli skin, etc.), pastries (such as Chinese pastry, western pastry, moon cakes, etc.) and edible decorations for cakes.

Among the wet noodle products, the amount of propylene glycol must not exceed 1.5 grams/kg;

In the pastry and edible decoration, the maximum amount of propylene glycol is 3 grams/kg.

According to the "Standard for Food Safety Standard Food Additives" (GB 2760-2014)

Therefore, as a food additive that is very toxic and allows the state, as a low toxic, the state is allowed to be added to some foods without exceeding the content, but the milk is not allowed to be added to the national standard. ②

In order to improve the flavor, some manufacturers will "add" fragrances in violation of regulations

According to the Red Star Capital Bureau, Before the "C. Trinol" storm, McWell was a "net red brand" that was popular on the entire network and was evaluated by consumers "stronger than other milk." ③

Dr. Yun, a popular science writer, Biological and Food Engineering Major, introduced in an interview with the Red Star Capital Bureau on July 3 that the fragrance spice is not allowed to be added to pure milk, but in order to improve the flavor, some manufacturers will "add illegally." In this case, it will not be a small amount of products or individual batches, but the same products will be detected. ③

The evaluation of McWer's "stronger pure milk incense" is related to the use of flavors (propylene glycol is fragrance solvents), and it needs further investigation.

What about people who have been drinking for a while?

Is it dangerous?

"People who have drank this brand of milk, do not need to be afraid to do medical examinations." On July 3rd, Dr. Yun, a professional and food engineering professional, said in an interview with the Red Star Capital Bureau. ③

He analyzed that the methanol content (0.32 grams/kg) was detected by the detective detected by Meloel, and 60 kg people drank 4.7 kg a day to "exceed the standard"; It is also in the "safe scope". However, Yun Wuxin introduced that although the meal of patelis with propylene glycol is not harmful to health, it is still a "unqualified product".

Yun Wuxin said in a report from Chinese consumers in 2019 that the addition of propylene glycol can make food better taste and keep a good taste longer. Although propylene glycol is a legal food additive, excessive consumption may also bring some dangers. ④

Yun Wuxin said that after people eat propylene glycol, about 45%of them will be discharged from the body through the kidneys, and the rest metabolized the lactic acid in the body. If the amount of consumption is too large, the lactic acid produced cannot be discharged in time, and it will accumulate in blood and kidneys, resulting in poisoning. It mainly affects the nervous system, causing slowing breathing, decreased heart rate, and loss of consciousness. ④

After the news of the "Meloel Pure Milk Unqualified" came out, Yun Wuxin posted on his Weibo on June 30 that propylene glycol appeared in pure milk, which was incredible. However, Yun Wuxin also reminded that referring to the "toxic-dose" relationship of propylene glycol, and the allowable dosage in other foods. The propylene glycol in these two batches of milk will not cause harm, so you don't have to tangle poisoning. ⑤

How to choose a good milk?

Chen Wei, deputy director of the clinical nutrition department of Peking Union Hospital, and Wang Lin, director of the Health Department of the Institute of Capital Pediatrics, said in the Health Time Newsletter in the Health Time News that the more simpler the ingredients, the better. Generally speaking, there is only raw milk in the ingredients of pure milk. Buy milk mainly for two points: protein and calcium.

As long as the protein content of milk is ≥2.9 grams/100 grams, the same is true of yogurt.

And other liquid dairy products, such as flavor yogurt, modulation milk, milk -containing drinks and lactic acid bacteria beverages, are reduced in turn, and such dairy products are often high in sugar, and the corresponding calories are relatively high. Essence

As for some fancy milk, such as high calcium milk and breakfast milk are not necessary. Milk itself is a high -calcium food. Even high calcium milk, its calcium content is much higher than ordinary milk, and the cost performance is not particularly high. Most of the breakfast milk is just milk with other flavors. Pay attention to whether its calories are higher than ordinary milk.

In short, milk and dairy products are foods that should be consumed every day. If you feel that drinking milk is too monotonous, you can choose to change between milk, yogurt, milk powder, cheese and other varieties. ⑥
