In this research work, sensorial features of four varieties of fresh apples have been investigated by children aged 6-10 years (n = 336) of the Centre-East region of Italy (Abruzzo). The examined sensory properties were visual appealing, aromatic flavour, sourness, sweetness, firmness and crunchiness. Statistical analysis was performed by means of principal component analysis which underlined the differences and similarities between the examined fruits and the most responsive variables. Results are very interesting and allow to better understand the most important descriptors which influence the appreciation of the different tested varieties. Furthermore, it has been noted that different varieties influence each other for the perception of some sensory characteristics. Thus, improving the knowledge of the most appreciated organoleptic properties of apples by young consumers would be very useful and it might stimulate the development of new and more appealing cultivars in the future.
