Systems were prepared at least 24 h before testing, were
stored at 4 1C for a period not longer than 1 week.
Two different groups of 20 trained assessors took part in
the study. A group (13 females and 7 males) judged only
sweetness of the systems. Another group (15 females and 5
males) was required to breakdown overall intensity of the
systems into sweetness and sourness. Each group made the
evaluations in three replicated sessions.
