The sensory profile was constructed by using a 12 judges
trained panel (UNI EN ISO 8586, 2008), consisting of students of
the DISPA.1 In a few preliminary meetings, by using commercial
and Besana samples, the judges have generated a list of descriptors
based on the percentage of citations referring to appearance,
olfactory, gustative and mouthfeel attributes. The final set consisted
of 15 descriptors for peeled samples and 20 descriptors for
unpeeled samples; the descriptors for both samples are reported
in Table 2. The different descriptors were quantified using a nine
point intensity scale where the digit 1 indicates the descriptor
absence while the digit 9 the full intensity. Evaluations have been
lead in single boxes at the DISPA sensory analysis laboratory. The
order of presentation was randomized between judges and
sessions. Water was provided for rinsing between samples.
All data were acquired by a direct computerised registration
system (FIZZ Byosistemes. ver. 2.00 M, Couternon, France)
