Abstract
By using the genetic selection technique, a new olive genotype, such as Favolosa (Fs17), considered to be either a cultivar or a dwarfing rootstock, was obtained. The composition of oil samples from the new genotype, collected in different Italian geographical origin areas, was investigated in-depth. The analytical profile of both saponifiable and unsaponifiable fractions of these oils has been elucidated, paying special attention to the components more related with quality, typicality, and genuineness. The results achieved pointed out that although the characteristics of the analyzed oils was quite dependent on the climatic and pedological features of the production area, the overall composition of the new product appeared to be comparable with that of well-known oils from the more popular and widespread Italian olive cultivars. It is to be emphasized its good concentrations of antioxidant phenols, tocopherols, volatiles, lipochromes, oleic acid and other bioactive components related either with flavour, aroma, shelf-life, or with the nutraceutical and health-promoting properties. Based on these first results, further agronomical, technological and analytical studies on the new cultivar Favolosa (FS17) should be stimulated so as to make available a highly representative sample of experimental data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
