ABSTRACT:
A method for quality control of products from fish, meat, cattle, swine and poultry, for instance for controlling a process for treating or handling such products. The product to be subjected to quality control, or a sample thereof, is exposed to electromagnetic radiation within the range of about 325-360 nm, preferably about 340 nm, and any fluorescent radiation emitted by the product as a result of this irradiation, is analyzed for identifying characteristic fluorescence from biological components in the product or a sample thereof, the presence of such biological components determining the quality of the product. The quality control is carried out in dependence upon the analysis result. Analysis carried out in the wavelength range of about 365-490 nm permits identification of characteristic fluorescence from bones, cartilage, connective tissue and/or fat.
