The present invention relates to a smart sanitary chopping board including: a flat panel-shaped chopping board main body providing a processing region for the food material a cooling unit disposed on one side in the chopping board main body and cooling air inside the chopping board main body a sensor unit disposed on one side on the chopping board main body and detecting at least one of component information of the food material a food material estimation unit estimating the type of the food material based on the detected component information of the food material and a temperature regulation unit disposed above the cooling unit on one side in the chopping board main body and regulating the cooling temperature on the upper surface of the chopping board main body by regulating the amount of supply of the cooled air to the upper surface of the chopping board main body depending on the estimated type of the food material. According to the present invention, the temperature of the upper surface of the chopping board main body is regulated depending on the type of the food material and a temperature suitable for the food material is provided, and thus the processed food material can be maintained fresh during the food material processing the loss of characteristics of the food material can be minimized, and cooking quality can be improved. In addition, a user is provided with weight information or the component information including the salinity, sugar content, and moisture content information of the processed food material, and thus the amount of an additive added during cooking can be appropriately regulated based on the component information of the food material and cooking can be performed to suit the user&primes preference. Furthermore, an appropriate amount of the food material can be easily prepared based on the weight information of the food material, and thus cooking can be easily performed even by novices. Moreover, a sterilizing cover portion sterilizing the p
