A central location test was conducted with 145 consumers each assessing 4 pieces of pork loin. Samples varied with respect to two factors: actual meat type (boar vs. standard pork) and label information (young boar meat vs. pork). Androstenone and skatole levels in the tested boar meat ranged from 0.51 to 2.72 mu g/g and 0.01 to 0.23 mu g/g melted fat, respectively. Consumers' sensitivity to and appreciation of androstenone and skatole odour was determined through a smell experiment. The acceptance of taste, tenderness, juiciness, and overall liking was neither influenced by the label information nor by the meat type. Twenty-seven % of all participants were classified as insensitive to androstenone odour, whereas 52% perceived it as positive and 21% as negative. Consumers who disliked the androstenone odour indicated a higher disliking of boar meat. (C) 2012 Elsevier Ltd.

Odor detection thresholds for androstenone and skatole are assessed as well as the subject's ability to identify odorants at various levels through easy-to-use paper smell strips.

Odor discrimination, odor identification, and odor detection thresholds were studied. Furthermore, a sensory quality control task using 40 boar samples was performed. All tests were accomplished both with and without extraneous noise recorded at an abattoir (70 dB) using headphones. Contrary to the researchers' expectations, abattoir noise hardly affected the olfactory tests nor was the quality control task impaired.

Therefore, fat samples were collected from 1000+ entire male pig carcasses for sensory evaluation and quantification of boar taint compounds using gas chromatography mass spectrometry (GC-MS). Each sample was sniffed by 10 trained assessors, resulting in 11 000+ individual ratings, which were subjected to statistical analysis. Pearson correlations of chemical traits and sensory traits (panel average) were higher for skatole [r(1029) = 0.59; p < 0:001] than for androstenone [r(1029) = 0.44; p < 0.001]. Linear terms of androstenone and skatole as well as their interaction significantly (p < 0.05) contributed to perception of deviant smell (R-2 = 0.43). Standardized regression coefficients illustrate the higher importance of skatole = 0.68) than androstenone (beta = 0.39). Interindividual differences in the responses of assessors to androstenone and skatole are confirmed. A new curved approach is suggested because it better accounts for the interaction of androstenone and skatole than the \"safe box\" approach. On the basis of these data, sorting strategies using instrumental measurements are discussed. An automated detection based on only skatole measurements is recommended because its performance is only slightly inferior to a sorting based on both androstenone and skatole.

The occurrence of an off-odor in the fatty tissue of the fattened, uncastrated male pigs, however, continues to hinder the widespread adoption of this method in Europe and, in this case, Germany. Castration is, indeed, a longstanding method but it was usually implemented for breeding purposes and aggression reduction.
