<P>PROBLEM TO BE SOLVED: To provide a metmyoglobin ratio measuring method for meat or fish, that allows a metmyoglobin ratio to be measured with high sensitivity, high accuracy and simplicity, even in a region of a low metmyoglobin ratio. <P>SOLUTION: Provided is a metmyoglobin ratio measuring method for meat or fish, in which: a primary correlation equation is derived in advance from a relation between a wavelength x(nm) taking an absorption peak of a light absorption spectrum measured at a wavelength of 350-450 nm, and a metmyoglobin ratio y(%) obtained by measuring absorbance for a plurality of predetermined wavelengths in a wavelength range of 500-760 nm and by including the absorbance in a predetermined relational expression, with respect to meat or fish to be measured, while if at this point there is a measurement value (x and y) for which it is determined that lean meat and dark meat are mixed in the measured meat or fish, this measurement value is excluded in deriving the primary correlation equation, and with respect to the meat or fish to be tested, the light absorption spectrum is measured at the wavelength of 350-450 nm, and the metmyoglobin ratio is calculated from the wavelength value that takes an absorption peak in the measured light absorption spectrum and from the correlation equation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
