However, propylene glycol is only approved for food additives as food additives (such as noodles, dumplings, ravioli, burning skin) and pastries in China. The maximum use of wet noodle products is 1.5g/kg, and the maximum usage of pastries is 3.0g/kg.

Liquid milk is not approved to use the food additive!

In the pharmaceutical industry, propylene glycol is often used to make various types of ointments, solvents, softeners, etc. In addition, propylene glycol is also used as a solvent and softener for cosmetics.

▶ will be added to the feed in the animal husbandry industry

Zhang Yimin, Director of the Second Department of Kidney Affiliated to Sun Yat -sen University, pointed out that propylene glycol is still a kind of raw sugar substance. In the animal husbandry, it is added as a nutritional ingredient to prevent cows from being caused by abnormal fat metabolism. Keto acid poisoning can also increase the yield of milk.

What about people who have been drinking for a while?

Is it dangerous and serious?

The safety standards formulated by the international food additive joint expert group (JECFA) are: the intake of the human body per kilogram of weight per day does not exceed 25 mg per day.

The popular science writer and doctor of food engineering pointed out that about 45%of people after eating propylene glycol, and about 45%of them will be discharged from the body through the kidney, and the rest are metabolized in the body as lactic acid.

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. Poisoning mainly affects the nervous system, such as slowing breathing, decreased heart rate, loss of consciousness, etc.

However, for people with normal liver and kidney function, the metabolism and excretion of propylene glycol are very fast, and poisoning at this degree will hardly appear.

The propylene glycol content detected in pure milk is 0.318g/kg ~ 0.321g/kg, which is lower than the amount of use as a food additive, and it is also within the scope of human intake.

Therefore, consumers who have bought or drink the brand of milk do not have to worry about physical problems, and they will not cause harm to the body in terms of dosage.
