Sensory evaluation
The frozen yogurt and two probiotics
frozen yogurts formulae were evaluated among
sixty panelists, using 9-point Hedonic Scale
method. Two columns of attribute evaluation,
namely Liking (“dislike extremely” (1) to
“like extremely” (9)) and Intensity (Lowest
intensity (1) to Highest intensity (9)) were
included in the sensory evaluation questionnaires.
The attributes evaluated in the test
were aroma, texture, sourness, sweetness,
creaminess, color, and melting, and the
overall acceptability. The mean scores of
Liking and Intensity for each attribute and
the overall acceptability were calculated.
All data were statistically analyzed by
using Analysis of Variance. The means of
the treatments that were significant at the
0.05 level of probability were separated
by Duncan’s Multiple Range Test utilizing
Sirichai program. (Dr.Sirichai Unsrisong,
