3.2.2. Sample description and differentiation according to sensory characteristics
Besides the scores for the parameters, a data collection about sensory characteristics of each sample was obtained. In addition to giving an exhaustive description of the sample, as the sensory characteristics by the assessors determine the score (by using the decision trees), the reasons for the scores can be known.
In Table 5 the citation frequency (CF) of the different sensory characteristics is shown. In the case of odor, the most cited characteristic was the ideal one (“cooked meat and fat odor, with similar intensities or slight dominance of cooked meat”), with slightly more than half of the assessors mentioning it. The second most cited characteristic was liver odor, with highest CF for “liver obvious”, followed by “liver slight” and a very low CF for “liver excessive”. The sum of these three categories is 44%. Fatty absence presents a CF of 21.4%. The rest of characteristics, including defective ones, presented lower CFs.
