Stirred-type
fruit-flavored yogurt was made by adding cornelian cherry paste and sugar at different
ratios. The effects of the paste and sugar addition on the physicochemical and organoleptic
properties of yogurt were examined. The titratable acidity, pH, viscosity, whey
separation, and organoleptic properties of experimental yogurts were determined
at weekly intervals for 21 days. Statistically significant differences were
found between the control and fruit-flavored yogurts in terms of viscosity and
whey separation. The addition of the fruit paste and sugar to yogurt resulted
in an increase in the whey separation, and a decrease in the viscosity. During
the storage, the values of the titratable acidity, viscosity and whey
separations of experimental yogurts increased, while pH of the yogurts decreased
significantly (P < 0.01). Yogurt with 10 kg/100 kg fruit paste and 10 kg/100
kg sugar was more acceptable and high scored with respect to overall
acceptability value by panelists; however the result was not significant
statistically.
