The products were evaluated by an
untrained panel consisting of thirty-six panellists (13 males and 23
females) from the students and the staff members of the National
School of Engineer (Sfax, Tunisia). Their ages ranged from 23 to 50
years. The syrups were evaluated based on a seven-point hedonic
scale, where one represented “disliked extremely” and seven represented
“liked extremely”. Each consumer was given 6 samples
labelled with random 3-digit codes simultaneously and asked to
evaluate the syrup for appearance, taste, odour and texture. The mean value of these sensory proprieties was evaluated as overall
acceptability.
