Cluster analysis showed three groups of sensory attributes
(Fig. 3A): one group for hardness and adhesiveness and another
group for the attributes of crispness and fracturability, while chewiness
was kept in a separate group. Groups are formed based on
Euclidean distances, which means that values of hardness and
adhesiveness and of crispness and fracturability are proximal between
them, while values to chewiness is more distant from the
others attributes.
