The blood oranges accumulate anthocyanins in their peel and pulp, which give them their characteristic red colour. To investigate whether there is a specific volatile compounds profile for blood oranges, we compared the volatile composition of the blood varieties 'Moro', 'Tarocco Rosso' and 'Sanguinelli' to that of the blond ones 'Cadenera', 'Salustina' and 'Hamlim' using a non-targeted approach based on HS-SPME-GC-MS. Moreover, fruits from each blood orange variety were divided into slightly and intensely pigmented fruits, and individual sugars and anthocyanins were determined by liquid chromatography to investigate whether their profiles depend on the degree of pulp pigmentation.

A panel of 94 consumers took part in the study. Attention paid to label components during the task designed to evaluate the logos' effect on expectations was recorded by means of an eye-tracker.

In this study, a total of 12 pomegranate varieties were evaluated, including commercial (Valenciana, Illina, Tastem, Rugalate, Wonderful, Mollar 49 y Mollar 45) and new varieties (Ref 102, Ref 383, H3/27, and D27/12). For the first time, consumers not only scored their acceptance of different pomegranate varieties but also described their sensory properties using CATA questions.
