<p>Boar taint in individual carcases of uncastrated boars or parts thereof is determined in a fast and simple manner by determining IR-spectrophotometrical transmission data for the individual carcase or part or preferably on a sample from the carcase or part, and comparing the spectral data registered with corresponding data having a statistical relationship to boar taint. A suitable determination is determination of the ratio between the absorptions at two different wave lengths in the range of 1275 - 1325 cm<s-1>s in the IR spectrum of the fat sample. A still higher correlation between the particular spectral data and the organoleptic data is obtained when one or more further parameters with statistical correlation to the odour image is/are included, e.g., the concentration of unsaturated fatty acids in the fat of the boar carcase.</p> |
