Northern Italy / D. Tura, O. Failla, S. Pedò, C. Gigliotti, D. Bassi, A. Serraiocco. - In: ACTA HORTICULTURAE. - ISSN 0567-7572. - 791:(2008), pp. 769-776. (Intervento presentato al 5. convegno International symposium on olive growing tenutosi a Izmir, Turkiye nel 2004).
Abstract:
Composition and quality profiling of olive oils from two cultivars (‘Casaliva’
and ‘Leccino’) in seventeen olive groves were studied for four years (1998-2001) in
“Garda Bresciano” area (western cost of lake Garda, northern Italy), in relation to
seasonal weather fluctuation in term of air temperature and rainfall. Fruits from
adult trees of average growth and yield were harvested individually in each orchard
and the oil was extracted at fruit veraison. All oil samples were obtained by a
laboratory oil mill within one day from picking. The olives were crushed, malaxed
and oil was extracted by hydraulic press and separated by centrifugation. All oils
were classified as “virgin”. Polyphenols, tocopherols and volatile compounds were
analyzed. Total polyphenols, tocopherols and volatile compounds resulted negatively
correlated to maturity index, whereas ‘Casaliva’ cultivar was positively correlated to
heat summation during olive maturation (from August to October).
