Food packed in plastic bags for too long is equal to "poison"

summary

Because I am a high school student, because I always eat in the restaurant, which is a problem that many people are very concerned about. Sometimes I will bring the restaurant food back to the dormitory to eat. But the food that needs to be packed in the restaurant will always be packed in plastic bags. I always feel that the plastic bags will contain toxins and penetrate into the food. Sometimes go out to buy some vegetables, fruit will also be put in plastic bags, until eating time will take out to wash. It's said on the Internet that the toxin in the plastic bag will penetrate into the food, but my friends say it's OK. Is this true? Is it really harmless to pack food in plastic bags? Let's take a look at the following.

Food packed in plastic bags for too long is equal to "poison"

First: even qualified food bags can't keep food for a long time. Plastic products are only relatively safe. They are high polymer chemicals. And in the market there are all kinds of toxic plastic bags, sometimes it is difficult to distinguish the true and false plastic bags. In this kind of poisonous plastic bag, vegetables with fresh, water vapor and pesticides are more likely to deteriorate in a day or two, and produce other harmful substances.

Second: when buying vegetables, try to use the shopping bags you have prepared. If you buy plastic bags in the market, if they are non food special plastic bags, you must add 15 places when you get home. Even if the storage time is not long, you should also store them open. Try not to use colorful plastic bags, let alone black plastic bags with heavy toxins. three

Third: some families are used to using plastic film to seal up the food, but this method is actually wrong. The chemical reaction between food preservative film and food makes it difficult to disinfect even with high temperature. In particular, the preservative film can not be pasted on the food, this toxin is difficult to remove, great harm to the body.

matters needing attention
