This classification was linked to the consumers characteristics via a x2 test (table 3). It was expected that sensory perception of water could be influenced by the subjects charateristics (gender, age, place of residence or consumer habits concerning water), but in fact, no link was found between this classification and the characteristics of the subject. Thus, the differences between the subjects with regard to perception may be essentially due to physiological characteristics and not to consumer habits.Consumers preferences and consumers behavior After having encoded the preference verbatim as described in the third part of the data analysis section, a multiple comparison test (LSD, P=0.05) was performed in order to extract the significant differences between the means obtained by each water. Results are presented in Table 4 where the mean preference of the water samples (ranging from -1 to 1) is reported together with the TDS. In this table, the two water samples with the same lettter (A to E) should be considered as equally liked by the consumers. It is clearly confirmed that maximum preference is obtained for balanced mineralization (around 300mg/L). the further the water is from this medium mineralization, the more it is disliked (except for tap water 6, which is disliked because of its off-flavor). the three most disliked water samples were the extreme types of water: bottked water samples 5 and 6 on the one side (highly mineralized) and bottled water 1 on the other side (poor in minerals).
