Abstract

We are using a trained sensory panel to define the sensory attributes profile of a wide number of apple commercial cultivars and new selections under evaluation at FEM (Fondazione Edmund Mach). The same fruit are evaluated through instrumental determinations as well. Here we present the correlations found between perceived odours (by trained panel) and volatile compounds (by SPME‐GC‐MS) in 18 apple cultivars. It is known that perceived odours are mainly the result of mixture of odorants (more than 300 compounds that can contribute to apple odour and flavour have been identified) and the single components of a mixture may lose their individual identity and a new mixture with a specific odour quality could emerge. Thus the correlations between odours and volatile compounds in apples were investigated by a multivariate approach. Regression models allowed the identification of compounds highly contributing to the odours arising from the complex mixture of volatile compounds released by apples. For example acetate esters strongly contribute to different fruity attributes and the results suggest that perceived odours are due to the relative proportions among esters rather than their presence/absence. In conclusion, sensory and instrumental profiling in combination with appropriate chemometric analyses can help to elucidate the relationships between the perceived odours in real food and the complex mixture of released volatile compounds.
