Problem description:

My mother and her neighbors buy breakfast. White food bags can be filled with hot soybean milk and fried dough sticks for breakfast. I always feel unsanitary, but I can't say why. It is said that the substance on the surface of the non-stick pan is toxic, and my rice cooker also has non-stick substances. My family often uses it to make rice and soup. Is it unhealthy? Can someone explain? Help everyone get rid of some bad habits in life?

Analysis:

Plastic bags can be roughly divided into two types: one is new plastic and the other is recycled plastic. Article 7 of the Measures for Hygienic Management of Plastic Products and Raw Materials for Food stipulates: "Recycled plastics shall not be used in processing plastic tableware, containers and food packaging materials. Plastic products for food must be printed with the words' for food' in a conspicuous position. " Real food plastic bags are made of new materials. The main raw materials are polyethylene and polypropylene. They are odorless, nontoxic and relatively transparent. They can hold food and have the words "for food". The so-called food plastic bags, especially colored plastic bags, which are common in the market are mostly recycled plastic bags. The main raw materials are recycled waste plastics, industrial wastes and medical wastes. After separation, cleaning and heating, they are made into granules and sent to a film blowing machine. These materials themselves may contain a lot of toxins.

In addition, additives such as colorants, plasticizers, lead and salt are added to the recycled plastic bags during the treatment. These harmful substances are easily dissolved in food when oil is exposed to high temperature. Once they enter the human body, they will cause cumulative poisoning and damage the liver, kidney, reproductive system and central nervous system.
