This study evaluated the sensory characteristics of diet strawberry flavored yogurt enriched with whey protein concentrate (WPC). Three formulations containing 0,5%, 1% and 1.5% of WPC (F2, F3 and F4 in order of increasing concentration) and a controlled formulation without the addition of WCP (F1)  were developed and evaluated by Ranking Descriptive Analysis. Twenty selected and trained panelists evaluated the samples characterized by attributes: pink color, viscosity, characteristic aroma of strawberry yogurt, characteristic flavor of strawberry yogurt, sweet taste, sour taste and consistency. The formulations differed significantly (p < 0.05) in the attributes sweet taste and consistency. Samples F3 and F4 showed greater consistency confirming the efficiency of the WPC in increasing the consistency.
