The results of the triangle test analysis are shown in Table 3, where it can be seen that the panel was successful in identifying the authentic perfume (a successful result is considered when 70% of correct identifications are obtained). As can be observed, in most cases the assessors are capable of discriminating the different sample in the set of three. Only with the inspired 5, the panel is not capable of identifying the two authentic perfume samples in the triangle test, which prove the ability of an EOS to detect the best inspired perfume. Moreover, the Table 3 shows that the panelist had some problem to identify the inspired 3 and 4 perfume samples. Comparing the results of Table 3 with Fig. 3b, a similar order of proximity to the authentic perfume was obtained. The favourable results obtained in this work indicate that the EOS approach should be an attractive alternative to the common “triangle test” in the perfume industry since these tests require a panel of a least 18 persons and is generally too time consuming and labour-intensive for routine quality control application [13,17].
