A millimeter-wave reflectometer has been developed for the nondestructive measurement of the sugar content in apples. The intensity of the reflected wave from fruit was confirmed to depend on the sugar content and temperature by performing reflectometry with a vector network analyzer of aqueous sucrose solutions. Moreover, the developed reflectometer was applied to the sugar content measurement of apples. We obtained a strong, almost linear relationship between the intensity of the reflected wave and the sugar content in apples.
