Notes:
A visual profile panel (27 assessors) was developed for the evaluation of color and appearance properties of chilled dairy dessert gel products based on the Quantitative Descriptive Analysis (QDA) method (Stone et al. 1974). In the terminology development stage of the training procedure, assessors agreed on 29 visual cues to be used in the evaluation of chilled dairy desserts. Further training were based on these cues. Panel performance was analyzed using principal component analysis (PCA) and generalized Procrustes analysis (GPA). The panel exhibited good consensus over most of the color and appearance attributes with better agreement in attributes related to visual texture and flavor over color, gloss and opacity attributes. Assessors also displayed the ability to visually evaluate and discriminate between samples without the need to taste, smell nor touch.
