Use of masking strategies to avoid the boar taint perception in chorizo: consumers' acceptability

The production of entire male pigs is an alternative to surgical castration. However, boar taint may be present in the meat of entire male animals. The aim of the present paper was to investigate the acceptability and sensory properties of chorizo, elaborated under three different levels of androstenone [castrated 0-0.3 mg / kg, medium 0.4-0.9 mg / kg and high 1-2.75 mg / kg] and two masking strategies [rosemary, and rosemary plus smoking] using a Check-All-That-Apply questionnaire. The results showed that, of the strategies employed, the rosemary plus smoked chorizo was the most effective masking strategy to reduce the boar taint in chorizos with high androstenone level (3.7% selection rate for animal flavour), while the closest to the ideal product, according to consumers' description, was high androstenone level plus rosemary chorizo.
