"Poison" that shouldn't be there was detected in milk twice. What exactly is propylene glycol? Will drinking milk become unsafe?

You must have heard about the detection of toxic and harmful substances - propylene glycol - in a certain domestic brand of milk. I guess many people have begun to worry about whether they have drunk this problematic milk or whether the milk they drink has this problem. Don't be afraid, listen to me slowly. I suggest you like and forward it to more people.

First of all, we must emphasize three points. The first point is that propylene glycol is indeed toxic. The second point is that propylene glycol is an additive allowed to be added to certain foods. The third point is that it is very inappropriate for it to appear in milk because it is not allowed to be added to milk.

After talking about these three points, I guess you are both clear and confused. If this thing is poisonous, why is it a food additive? If it is not allowed, why does it appear in milk? Most importantly, is there this thing in the milk we drink? Will we be poisoned if we drink it occasionally?

Propylene glycol is a colorless, tasteless and odorless chemical that is flammable and highly absorbent. Yes, it is toxic and is an approved additive. However, its toxicity is very low. How low is it? According to the standards set by the International Joint Expert Group on Food Additives, for an adult weighing 70 kg, a daily intake of no more than 1.75 grams will not pose a risk. How much is in the problematic milk just mentioned? This amount should be difficult to achieve. The second one is right, it is indeed a food additive. It can be used as an efficient solvent for flavors and food colorings, and can also be used as a mold inhibitor and fruit ripening preservative. Of course, not all foods can be put in this thing, such as raw wet noodles, Chinese cakes, Western cakes, moon cakes, etc., and the milk just mentioned is not included here. Some people are worried that although propylene glycol has low toxicity, it also has risks. What if you eat too much? Don't be afraid, the amount added here is very low, and you will not be poisoned by eating too much.

Since propylene glycol should not be present in milk, why is it detected? Is there something wrong with the cow's feed? Propylene glycol is mainly converted into lactic acid after entering the body, and does not appear in milk in its original form. So, as to why it appears in milk, this still needs to be investigated by relevant departments.

Are other brands of milk safe to drink? Don't be afraid, the quality supervision department regularly checks the dairy products on the market, and any problems will be discovered naturally. The most important thing is that milk is a good thing that can supplement protein and calcium. It is recommended that you still insist on drinking milk. According to the 2022 dietary guidelines, it is healthier to drink 300-500 grams a day.

Regarding the detection of "propylene glycol" in milk, don't worry too much, and don't spread rumors. Believe in science, and believe in the truth.
