Abstract: The overall preference and sensory characteristics of 4 different flavors of citrus yoghurt including green orange（A）, sweet orange（B）, grapefruit（C） and lemon（D） flavor were evaluated. The overall preference was determined by the nonparametric Friedman test and the least significant difference（LSD） method in multiple comparisons. Sensory characteristics were evaluated by selecting ten sensory descriptors describing the flavor of yogurt for quantitative description analysis（QDA）. Partial correlation was used to analyze the relationship between overall preference and sensory characteristics at the same time. The results showed that the overall preference scores of the four products were ranked as follows: C＞B＞A＞D, meaning the most favorite was grapefruit flavored yogurt,followed by sweet orange and green orange flavored yogurt, and the least was lemon flavored yogurt. And at the5% significance level, C was significantly more popular than A and D, while B was obviously more popular than D. The four flavored yogurts had own distinguishing feature according to the sensory characteristics analyzed by QDA method. An analysis of the correlation between overall preference and sensory characteristics showed that the evaluators prefered the products with slightly stronger total aroma, creamy aroma, fermented flavor, and fruit aroma, slightly stronger sweetness, and thick, bitter-free taste, and exhibited inconsistent preference for the yogurts with astringent and granular mouth feel, and expressd lower preference for the products with too strong or too weak aroma, too high thickness, and too weak sour taste.
