Whether we go to a breakfast restaurant or order takeout, we often see this phenomenon: the boss skillfully tore off a plastic bag, then put it on the bowl, and finally put the food in it quickly. In fact, there is a reason for this. : Food is often stained with oil. If it needs to be cleaned, it means an extra labor. For the business model of “high volume and low interest” such as breakfast stalls, a cheap plastic bag can bring them Great convenience.
But there are also many people who are very resistant to this, thinking that plastic bags are “chemicals”. Compared with traditional porcelain bowls, they appear to be healthy on the surface, but in fact, they pose a great safety hazard to health. Especially when putting in “high-temperature food” such as noodles and soup that have just come out of the pot, you can clearly smell a plastic smell, which can be reluctantly accepted at light, or retching and hard to swallow at worst, causing some unnecessary “conflicts”.
So are plastic bags really poisonous after they are filled with hot food?
First of all, it is necessary to understand that plastic bags are made of “polyethylene”, “polypropylene”, “polyvinyl chloride” and so on. From a professional point of view, polyethylene does have the risk of precipitation of “toxic monomer ethylene”, but the possibility of precipitation of “food-grade polyethylene” is extremely low. The plastic bags that were spread earlier are generally made of “polypropylene”, because it has stronger high temperature resistance (160°-170°), and even if it is heated by microwave, it will not produce peculiar smell. According to the high temperature precipitation of food at 100°, there are almost no “poisonous monomers” in “polypropylene plastic bags”, but the premise is that the plastic bags used must be “food grade”.
Objectively speaking: the so-called “substance” in “polypropylene” does not mean that it is a toxic chemical. It is best not to eat it, but you don’t have to worry too much if you eat it.
