In the kitchen at home, plastic products abound, but the safety of plastic products is often easily overlooked.
Plastic products can be divided into three categories according to their components: one is made of polyethylene, polypropylene and melamine, which are non-toxic and harmless to the human body; the other is polyester, which was found by the American Space and Space Council , which is the most likely to release harmful gases of all compounds, such as PVC, etc., have been confirmed to be carcinogens; the third category is the utensils or bottles made of polycarbonate.
When these tableware are used to hold hot water and oil, phenolic methane will be released, and after absorption by the human body, the endocrine will be disturbed.
Metal elements such as lead and cadmium in the surface pattern of many plastic tableware can cause harm to the human body. Generally, there is a protective film on the surface of plastic products. Once the film is scratched, harmful substances will be released. Therefore, consumers should try their best to choose plastic tableware that has no decorative patterns, is colorless and odorless, has a smooth surface and feels strong. Consumers can choose plastic products marked with the words PE (polyethylene) and PP (polypropylene) on the products, which are relatively safe.
Experts believe that plastic wrap, wallpaper, water pipes and toys, etc., all contain plasticizers such as vinyl chloride, which are added to strengthen the hardness of plastic products. Dissolution of harmful substances.
In addition, it is best to choose high-heat-resistant polypropylene products for kitchen utensils, such as polypropylene fresh-keeping covers for microwave ovens, which will not be toxic when heated by microwaves; also avoid storing wax, detergents, etc. in plastic jars. Because these chemical gases will penetrate the plastic material after evaporation, which is not good for the body.
