ABSTRACT OF THE DISCLOSURE A meat freshness measuring apparatus measures freshness of meat by detecting changes in a pigment contained in the meat. For this purpose, the meat (2) is exposed to rays of light of different wavelengths applied from a light source (1), and the rays obtained from the meat are separated to spectra for the respective wavelengths, which are received by a photoelectric conversion element (4). Spectrum data for each wavelength is amplified and then the amplified data is converted to a digital signal by an A/D converter (7), whereby the digital signal is stored in a RAM (12). Based on the stored spectrum data and using a prescribed equation of calculation, a content of the pigment in the meat is calculated and outputted by a CPU (10). - 21 -
