Wooden cutting boards have high density, strong toughness, and very firm to use. However, due to the many types of wooden cutting boards, it is not easy to choose. Some wooden cutting boards (such as ebony) contain toxic substances and have peculiar smells. Contaminate dishes, and easily cause vomiting, abdominal pain, and dizziness. There are also some cutting boards with relatively loose wood, such as poplar cutting boards, which are not hard enough and easy to crack, and their surfaces are prone to knife marks. If they are not cleaned thoroughly, they can easily hide dirt, breed bacteria, and contaminate food. Therefore, it is recommended that citizens choose a cutting board made of white beech, ginkgo, saponaria, birch or willow with good overall quality in all aspects. Citizens should not buy the "three noes" cutting boards in the hands of small vendors. The cutting boards produced by regular manufacturers will be marked as wood. Before buying, it is best to smell the chopping board. If there is a sour taste, it is likely to contain sulfur, so don't buy it. There are also wooden cutting boards sold by small vendors. Compared with ordinary wood, the color of the cutting boards is slightly white. In order to reduce the cost, the cutting boards produced by these small workshops use inferior wood. The "whitening" of the cutting board is usually bleached with sulfur fumigation, and the residual sulfur dioxide will seriously harm human health.
The bamboo cutting board is slightly lighter than wood, not easy to fake, relatively stable in quality, and safer to use, but its density is not as high as that of wooden cutting boards, and the thickness is not enough. A small part of the board surface on the market is the whole bamboo unfolded surface. This cutting board surface does not use chemical reagents and is not easy to crack, but the price is slightly higher, and it is a new choice for health and environmental protection.
Although the plastic cutting board is lighter in weight and convenient to carry, it is easy to deform. When buying, pay attention to look and touch with your hands. Some rough-textured plastic cutting boards are easy to cut out the residue, which enters the human body with food, causing damage to the liver and kidney; some dark-colored plastic cutting boards are mostly made of waste plastic and have more harmful substances, so It is best to choose a plastic cutting board with translucent color, good quality, uniform color, no impurities and pungent odor.
