Abstract
Boar taint in individual carcasses of uncastrated boars or parts thereof is determined in a fast and simple manner by determining IR-spectrophotometrical transmission data for the individual carcass or part or preferably on a sample from the carcass 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.sup.-1 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 odor image is/are included, e.g., the concentration of unsaturated fatty acids in the fat of the boar carcass.
