<p>PROBLEM TO BE SOLVED: To accurately measure the taste value by using a near infrared analyzing method. SOLUTION: A near infrared light is emitted to sample powder 1 obtained by grinding the surface layer of polished rice, and the spectrum of the reflected or transmitted light is measured by a near infrared measuring instrument 2. A spectrum calculator 3 calculates the absorbance of the designated wavelength of the spectrum, and a calibration type calculator 4 substitutes the absorbance for a calibration formula to calculate the taste value. A display unit 5 displays the calculated result of the value. A control recorder 6 stores the wavelength which can explain the physically functional taste value of the powder obtained by grinding the surface layer of the polished rice and the formula for representing the relationship between the absorbance of the wavelength and the taste value, designates the wavelength which can explain the function taste value for the calculator 3, and designates the formula for the calculator 4.</p> |
