Is the plastic chopping block harmful to human body? How to choose plastic chopping block correctly?

1 Is the plastic chopping board harmful to human body? Generally, regular plastic chopping boards are harmless.

Regular plastic chopping boards should import high-quality food-grade PP raw materials. In principle, this is safe and non-toxic. However, in order to pursue the one-sided hardness of plastic chopping boards, some businesses often add too much filler, and even some unscrupulous businesses mix old raw materials into materials to reduce production costs, which may lead to the precipitation of chemical substances.

Therefore, when consumers buy plastic chopping boards, it is best to choose plastic chopping boards with translucent color, uniform color distribution, no impurities and no pungent smell. In addition, try not to use plastic chopping boards when cutting cooked food.

2 The correct selection method of plastic chopping block According to expert analysis, the main component of plastic chopping block is polyethylene or polypropylene, and there are strict safety indicators and requirements when using materials. The problem is that in order to increase the hardness of plastic chopping boards, that is, "durability" and "chopping resistance" that ordinary housewives often say, some manufacturers often add too much calcium carbonate and talcum powder as fillers, or even mix recycled raw materials to reduce production costs, which may lead to chemical precipitation.

Plastic chopping boards will not be "toxic and harmful" as long as the materials and materials are strictly controlled.

1. Consumers can also master some tricks when purchasing, such as whether the colors are uniform;

2. Whether the smell is pungent or abnormal;

3. Touch the product to see if there is powder on your hand (talcum powder and calcium carbonate will appear when added in excess).

In addition, when using, try not to cut overheated food, because high temperature will also accelerate the production or decomposition of harmful substances.

Advantages and disadvantages of plastic cutting board The advantages of plastic cutting board are 1, which is durable: for example, a cutting board with a thickness of 30-60mm is more suitable for home use, and such a cutting board can be used for more than 15 years. Less chips are dropped when in use.

2, more environmentally friendly: compared with natural materials such as bamboo and wood, plastic chopping boards are more environmentally friendly. Take the chopped wood pier (about 450mm in diameter) as an example. Every such wooden pier needs 30-50 years of trees. The contribution of big trees to the earth is self-evident, and it is really a pity to use them for cooking.

3. Good antibacterial effect: Another advantage of plastic chopping board is antibacterial. Compared with natural materials, it has antibacterial properties, and it is the least likely to breed bacteria because of its high hardness, no scratches and no seams. Meanwhile, it is easy to clean. It can be scalded with boiling water or washed with detergent, which is not easy to remain after washing. It can also be washed with a dishwasher.
