1, look at the characteristics. The willow chopping board is long, and the wood fiber is thin and hard. The chopping board made of willow has the advantages of no mud, water immersion resistance, no corrosion, smooth surface, cleanliness and hygiene, and long service life. Ordinary wooden chopping boards are made of maple, catalpa bungeana and Schima superba, so the wood is soft and easy to lose sawdust.
2. Look at the relative density. The willow chopping block has a large proportion of wood, which is submerged in water, but ordinary wood is not.
3. Look at the texture. Willow chopping block wood is twill with staggered texture, but ordinary wood is not.
4. Look at the hardness. There is no nail mark on the section of willow cutting board with thumb nail, but ordinary wood appears.
5. Listen to the sound. Wicker chopping boards rattle like iron when struck with a hammer, while ordinary wood rattles.
Second, the maintenance method of willow chopping board
1. Use a large plate (preferably plastic) into which you can put a wooden chopping board, put clear water in the plate (just above the surface of the wooden chopping board), put salt in the water (more than half a catty, less than a catty, depending on how much water you put), stir well, and then put it into the wooden chopping board and soak it continuously for one month.
2. After one month, take out the wooden chopping block to dry the water, then boil the vegetable oil and spread the hot oil cloth evenly on both sides of the wooden chopping block.
3. In a few days, when the wooden chopping block is dry, cut a shallow ditch on the side of the wooden chopping block with a knife, and then tie the wooden chopping block tightly with thick iron wire along this cut shallow ditch.
Extended data
The wooden chopping board is thick and tough, which is more suitable for cutting meat or some hard food. However, in use, it is easy to chop out the wood residue, mix it with meat dishes and eat it into the body, which is harmful to the health after a long time. In addition, the wood chopping block is used for a long time, and the cut marks are easy to accumulate scale and difficult to clean, while some wood, such as poplar itself, is easy to crack and is more likely to breed bacteria after repeated use.
Because of its strong water absorption, the wooden chopping board is not easy to dry. If it is left in a humid environment for a long time, it is easy to get moldy and lead to intestinal diseases. Therefore, it is best to soak the wooden chopping board in vegetable oil for 2 hours before use, so it is not easy to crack. When buying a cutting board, you must choose reliable wood, especially the cutting board made of ginkgo, acacia, birch or willow.
