<p><P>PROBLEM TO BE SOLVED: To accurately and nondestructively determine a sugar content of a produce 2 (for example, apple). <P>SOLUTION: The produce 2 is irradiated with a millimeter wave or terahertz wave, and an intensity of an electromagnetic wave reflected therefrom is applied to a comparison data preliminarily found as to the intensity of the electromagnetic wave and the sugar content, so as to determine the sugar content of the produce 2. The intensity of the electromagnetic wave reflected from the inspected object is confirmed to be smaller in the higher sugar content of the inspected object, in an experiment executed by an inventor of the present invention. Resultingly, the sugar content of the produce 2 such as the apple is determined accurately in the present invention, compared with conventional one of inspecting the sugar content of the produce 2 using a near-infrared ray. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
