Extract

Skatole is formed as a result of bacterial degradation of tryptophan in the rumen of cattle and sheep, and the hindgut of pigs. It accumulates in fat where it is an important component of boar taint in pigs (Claus et al, 1994), and with branched chain fatty acids, has been implicated as a contributor to the strong flavour characteristic of sheepmeat (Young et al, 1997). This study examines the role of breed, diet and age on skatole deposition in the fat and perception of beef flavour.
