Abstract Boar taint in individual animal bodies, preferably carcasses or parts thereof, can be detected by pre- paring an extract of a meat and/or fat sample from the body or part thereof, reacting said extract with a colour reagent, for which the colour intensity developed at certain wavelengths exhibit a statistical relationship with boar taint, determining the trans- mittance or absorbance of the reacted extract at one or more such wavelengths, and inserting the recorded values in the said statistical relationship. A high correlation has been found to exist between colour reaction and boar taint evaluation so that the transmittance or absorptance at wave lengths charac- teristic of the colour reaction gives a quantitative measure of boar taint intensity. This has made it possible to determine threshold values which objectively define organoleptic inacceptable taint levels. The method is fast and accurate and requires no extensive work; in addition it has been possible to automatize it so that it can be used directly in connection with slaughter lines in slaughterhouses for industrial control and sorting of individual carcasses.
