FIELD: medicine. SUBSTANCE: method involves exposing meat sample to monochromatic laser radiation having wavelength of 488 nm for analyzing resulting fluorescent luminescence in fluorescence band. The results are interpreted in terms of meat condition. Two spectral segments are selected in analyzing the fluorescent luminescence from fluorescence band by means of corresponding spectrum-selective interference filters. The segments have wavelength maximum of λ1= 510 nm and λ2=545 nm. Fluorescent luminescence intensities J1 and J2 are measured at the wavelength pointed out using corresponding photodetectors and J1 and J2 intensities are compared. J1 / J2 ratio being ≥ 1, the results of analysis are considered to be positive that means good quality of meat. The J1 / J2 ratio being <1, the results of analysis are considered to be positive that means the meat contains pathogenic bacteria. EFFECT: objective evaluation of meat quality. 2 dwg
