Evaluation of infestation by Lobesia botrana (Dennis et Schiffermüller) (Lepidoptera, Tortricidae) and its relation to territorial differences and cu…
2013
A three year study (2008-2010) was carried out in two organically managed vineyards in western Sicily to verify both the influence of different cultivars and microclimatic conditions on grape moth infestation and on mould infections of grapes. Observations were done on two autochthonous cultivars (Inzolia and Catarratto) and four international ones (Chardonnay, Cabernet Sauvignon, Syrah and Merlot). Results showed a different degree of infested grapes among the different cultivars in both farms but also a different level of infestation between the two farms for the same cultivar. Chardonnay was the most infested cultivar by the grape moth larvae, while Merlot was the less infested one. Botr…
Valutazione dell’infestazione di Lobesia botrana (dennis et Schiffermüller) in funzione alle differenze territoriali e alla suscettibilità varietale

Essential oil components of orange peels and antimicrobial activity
2016
In this study, the orange peel of 12 cultivars of Citrus sinensis from central-eastern Sicily was employed to obtain essential oils and extracts. The ones were extracted through steam distillation, the others through extraction in hexane. Chemical constituents were evaluated in terms of qualitative and quantitative analyses by gas chromatography/mass spectrometry. Fifty-four components were identified in the steam essential oils and 44 in the extracts. In all the cultivars, the main component is d-limonene (73.9–97%); discrete percentages of linalool, geraniol and nerol were also found. Cluster analysis based on essential oils composition showed a certain degree of affinity between cultivar…
Rheological and nutritional profile of spaghetti and bread fortified with hemp flours
2022
In recent years, the demands of food consumers have changed considerably. Food today is not only intended to satisfy hunger and provide the necessary nutrients, but also to prevent food-related diseases and improve the physical and mental well-being of consumers. Functional foods are formulated to contain healthy components, which when consumed daily as part of the diet, can have beneficial health effects. Cereal-based products, especially pasta and bread, are well suited for adding nutrients. Both bread and pasta, traditionally produced using durum wheat flour, can be prepared also using "non-wheat flours" in variable percentages or by incorporating food by-products, capable of increasing …
Sustainable sparkling base wines obtained from waste matrices of the wine and honey supply chain
2019
The present work was performed to improve the general quality characteristics of sparkling wines produced in Southern Italy (Sicily region) as well as the sustainability of the production process. To this purpose, two novel approaches were applied during experimental winemaking: (i), the use of raceme grapes (formed from the secondary shoots) of Grillo cultivar to improve the chemical characteristics of sparkling base wine; (ii), the technological selection of potential fructophilic Saccharomyces cerevisiae strains isolated from honey by-product to improve the alcoholic fermentations and the organoleptic features of bottled wines. The racemes are typical of Grillo cugrapes and mature 20 day…
Determination of the cultivar and aging of Sicilian olive oils using HPLC-MS and linear discriminant analysis
2010
A large number of certified samples (84) of Sicilian olive oils arising from the eight cultivars most represented in Sicily (Biancolilla, Cerasuola, Moresca, Nocellara del Belice, Nocellara Etnea, Oglialora Messinese, Brandofino and Tonda Iblea) have been collected and analyzed by HPLC/MS using an atmospheric pressure chemical ionization (APCI) source. The sample preparation is very simple; in fact, the oil samples are diluted without any chemical derivatization. A following statistical data treatment by general discriminant analysis (GDA) allows the determination of the olive oil cultivar. Furthermore, changes in the composition of glyceridic components of the olive oils lead to easy discr…
