IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Two strawberry cultivars (Fragaria × ananassa Duch.), ‘Miss’ and selection ‘94.568.2’ (‘Queen Elisa’), grown in two areas of North Italy, were investigated in 2002 and 2003. Objective physicochemical qualities of fruit, their storability and their sen-sory qualities were used to demonstrate the differences between the two cultivars and to improve their market acceptability. Since previous sensory evaluation in strawber-ries has shown that consumer preference is influenced mainly by sensory attributes including aroma, a second aim of this investigation was to characterize the volatile composition of the fruits of these two cultivars using GC-MS, GC-FID and GC-olfactometry (GCO) techniques. Objective and sensory results showed that ‘Queen Elisa’ had better characteristics (sweetness, acidity and firmness). Total content of aroma compounds analysed by GC-FID was higher for ‘Miss’. The GCO assays indi-cated that ‘Queen Elisa’ had a better odour profile than ‘Miss’. The latter cultivar showed a high sensory perceptibility of methyl butanoate, and of a compound not identified, associated with unpleasant odours (seasoned cheese and sulphurated smell).
