Sensory profile evaluation of light peach tea

In this work, three different brands of light peach iced tea (A, B and C), purchased in a local market and packed in PET bottles were sensory analyzed. At first, Quantitative Descriptive Analysis (QDA) was conducted in order to obtain the sensorial profile, with eleven tasters, previously selected and trained. The product acceptance was evaluated by 33 consumers, representing the target public. The QDA results were submitted to ANOVA, Tukey's test and Principal Component Analysis (PCA). The sample A was mainly characterized by banana aroma and flavor; the sample B by artificial peach aroma and refreshment; while the sample C by sweetness and natural peach aroma. The acceptance test, analyzed by ANOVA and Tukey's test, showed a greater acceptance for the sample C. The colour of the samples was evaluated by the Cielab L*a*b* method and the sample C stood out by the red colour.
