PURPOSE:To provide a method for inspecting the internal quality of vegetables and fruits without cutting or damaging them. CONSTITUTION:In the method for inspecting the internal quality of vegetables and fruits, a power supply means 1 feeds power at first to an AC field generating means 2 thus generating an alternated magnetic field. A sample vegetable or fruit 100 is then placed in the alternated magnetic field and the magnitude and phase of conduction current, variable depending on the electric resistance which varies in accordance with the internal quality of the vegetable of fruit 100, are measured, Subsequently, an eddy current is measured from the conduction current and the internal quality of the vegetable or fruit is decided based on the magnitude of the eddy current.
