According to expert analysis, the main component of plastic cutting boards is polyethylene or polypropylene, and there are strict safety index regulations and requirements when using materials. The problem is that in order to increase the hardness of the plastic cutting board, some manufacturers often add calcium carbonate, talcum powder, etc. as fillers, and even mix recycled old raw materials. In order to reduce production costs, it may lead to the precipitation of chemical substances.
Plastic cutting boards will not be "toxic and harmful" as long as they strictly control the materials used and the materials.
1. Consumers can also master some tricks when purchasing, such as seeing whether the color is uniform;
2. Whether the smell is pungent or abnormal;
3. After touching the product, check if there is any powder on your hands (adding talcum powder and calcium carbonate over the standard will cause powder to appear).
In addition, you should also try not to cut hot or hot food when you use it, because high temperature will also accelerate the production or decomposition of harmful substances.
