Significant differences in descriptive properties were found in
the yogurt drinks because of the addition prebiotic (FOS) or synbiotic
(FOS and Lafti-L10). The higher intensities of sour and yeasty
aroma and lower sweetness differentiated the synbiotic samples
from the control samples and the samples containing only prebiotic.
The consumer results indicated that the whole milk based
yogurt beverages were liked over the skim milk yogurt beverages,
with the whole milk beverage containing the prebiotic being the
most acceptable. Inclusion of a synbiotic had a negative impact on
the acceptance by the consumers, with the skim milk beverage
containing synbiotic being the least acceptable.
