The composition of bamboo salt is sodium chloride, which contains trace elements such as calcium, potassium, copper, iron and zinc.

The baking temperature of bamboo salt is as high as 1000 to 1300 degrees. At this temperature, organic matter will be burned, leaving only inorganic matter. Bamboo salt is actually another form of "crude salt". The research of Korean scientists points out that refined bamboo salt may contain some other minerals, and it is found that the content of manganese, calcium, zinc, iron and sulfur in bamboo salt is higher than that in pure salt or original salt. This is also in line with the material balance in chemistry-bamboo and loess contain more such components, which eventually enter the salt after baking.
