We analyzed whether the use of the Bluetooth salinity meter could affect the proper level of salinity in childcare centers. This study was conducted on childcare centers that wish to participate in the sodium reduction project (Bluetooth salinity meter using group, BG) and those that did not participate (Bluetooth salinity meter not using group, NG) among childcare centers registered with Center for Children's Foodservice Management in Anyang from January to December 2019. As a result of comparing the salinity and sodium contents of the soup according to whether or not a Bluetooth salinity meter was used, the salinity and sodium contents of BG was significantly lower than that of NG (p < 0.0001). Salinity and sodium contents in soups tended to decrease as the number of use of the Bluetooth salinity meter increased (p = 0.020). In conclusion, Bluetooth salinity meter can be used as a means to induce voluntary salinity control by cookers regarding sodium reduction education at childcare centers.
