Results of the acceptability test are shown in Fig. 5. In the case of
commercial chocolate milk with SPC and vitamins, it did not show
changes in the acceptability with respect to the commercial product without liposomes. This result was maintained with or without knowledge of what was being evaluated. This result agrees with
the triangular test which showed that commercial chocolate milk
with this liposomal formulation did not provide sensory changes
with respect to the commercial milk without liposomes. In chocolate milk with SPC:SA and vitamins, although there
were significant differences presented in the triangular test, in this
evaluation it was found that this difference could modify acceptability.
Thus, commercial milk with this liposomal formulation
had significantly lower acceptability with respect to the commercial
milk without liposomes, when the panelists did not know what
was evaluating. Although it should be noted that milk with a nutritional
promise seems to generate a positive effect based on the fact
that when the evaluators knew what they were judging, there were
no significant differences in milk samples with or without
liposomes.
Finally, in milk with SPC:CaS and vitamins, although the triangular
test showed differences, this liposomal formulation would
not be affecting the acceptability because both milk samples with
or without liposomes were not significantly different in trials with
panelists that did not know what they were tasting. Again, as in the
case of milk with SPC:SA, knowledge of the nutritional promise
produced a positive effect with a score significantly higher respect
to the milk without liposomes.
From the obtained results, it can be concluded that the addition
of liposomes in milk not only adds nutritional value but also, in the
case of SPC, does not affect its acceptability or differs from commercial
milk. Moreover, in the case of SPC:CaS, it does not only
affect the acceptability but it is increased when the nutritional promise
is known. Finally, the SPC:SA system, although it has differences
and showed lower acceptability, knowledge of the
nutritional promise generated a positive effect on the acceptability
of milk. Our results demonstrate an excellent acceptability of
potential consumers when knowing that they are drinking the
functional milk, which means an advantage in the sale and consumption
of the product.
