2. Nasi A, Mercurio V, Ferranti P, Avara V, Ad<strong>di</strong>manda G, Chianese L. Determinazione dellacomponente aromatica varietale quale marcatore <strong>di</strong> processo e <strong>di</strong> conservazione <strong>di</strong> viniautoctoni campani. In Ricerche e Innovazioni nell’Industria Alimentare, Vol 8. (S. Porrettaed. – ISBN 97888-96027-00-4), pp 6-10, 2008Varietal odorous components (terpenes, norisoprenoids, pyrazines, etc.) are the expression of vine genetic characteristics,and their determination can be important in the valorization and defense of typical wines and autoctonegrapes. In ad<strong>di</strong>tion to the “terroir,” the winemaking and conservation con<strong>di</strong>tions can mo<strong>di</strong>fy the varietalcomponents and harm the wine typicalness. In this study the varietal aroma composition of Aglianico wine wasdetermined on <strong>di</strong>fferent con<strong>di</strong>tions of conservation during the ageing step: in inox recipients (5000 L) and in twoother wood tanks (228 L and 3000 L respectively). The varietal aroma composition resulted preserved better inthe inox tanks. In order to preserve the varietal odorous composition and increase the shelf-life in bottle of Fianowine, con<strong>di</strong>tions of temperature, light and time resulted very crucial. High temperatures produced an increase ofterpene interconversion and degradation, and production of terpenyl oxides and p-cymene.3. Mazzuca P, Ferranti P, Picariello G, Chianese L, Addeo F. Mass spectrometry in the study ofanthocyanins and their derivatives: <strong>di</strong>fferentiation of Vitis vinifera and hybrid grapes by liquidchromatography/electrospray ionization mass spectrometry and tandem mass spectrometry.J Mass Spectrom. 40:83-90, 2005A mass spectrometric-based procedure for anthocyanin profiling was set up to <strong>di</strong>stinguish authentic Vitis viniferafrom hybrid red grapevine cultivars. 3-O-Monoglucoside and the related acetyl-, p-coumaryl- and caffeoylmonoglucosideanthocyanins occurred only in Vitis vinifera, whereas 3,5-O-<strong>di</strong>glucoside and the substituted acetyl-,p-coumaryl-, feruloyl- and caffeoyl-<strong>di</strong>glucoside anthocyanins were the ad<strong>di</strong>tional pigments in hybrid grapevines.The procedure was applied expressly to identify red grape cultivars based on the anthocyanin chemo-typedetermination. In particular, a red grape cultivar, having 3,5-O-<strong>di</strong>glucoside anthocyanins and a novel class of anthocyaninmonoglucosides, such as cyani<strong>di</strong>n-3-O-, cyani<strong>di</strong>n-3-O-(6-O-acetyl)- and cyani<strong>di</strong>n-3-O-(6-O-pcoumaryl)pentoside,was classified as hybrid. A second vine cultivar, characterized exclusively by 3-Omonoglucosideanthocyanins, was included among the Vitis vinifera species. Anthocyanin profiling by massspectrometry could represent the core of a chemotaxonomic procedure for <strong>di</strong>stinguishing American and Europeangrapevines based on the identification of post-synthetic anthocyani<strong>di</strong>n mo<strong>di</strong>fication.4. De Pascale S, Petrucci L, Limone F, Calabrese Mg, Quarto M, Caira S, Chianese L.Caratterizzazione <strong>di</strong> uve autoctone campane me<strong>di</strong>ante l’approccio metabolomico. Atti GiornateScientifiche Interpolo. Napoli, 20-21 settembre 2007, pp. 275-280La <strong>di</strong>fesa da imitazioni per l’uso <strong>di</strong> cultivar e processi produttivi non previsti nella tecnologia <strong>di</strong> produzioneco<strong>di</strong>ficata nei relativi <strong>di</strong>sciplinari, può essere realizzata solo su basi obbiettive me<strong>di</strong>ante la rilevazione <strong>di</strong>molecole varietali come terpeni e polifenoli in quanto espressione del metabolismo secondario dell’uva. A talfine, nel presente lavoro, vengono riportati i risultati relativi alla caratterizzazione <strong>di</strong> polifenoli e terpeni <strong>di</strong> uve abacca rossa (Aglianico, Pallagrello rosso e Sciascinoso) e bianca (Pallagrello bianco) me<strong>di</strong>ante cromatografialiquida e gassosa accoppiata alla spettrometria <strong>di</strong> massa.La determinazione del contenuto <strong>di</strong> polifenoli totali come anche quello delle singole componenti, antociani etannini, ha permesso <strong>di</strong> <strong>di</strong>scriminare le tre uve a bacca rossa per il più elevato contenuto <strong>di</strong> polifenoli totali nelPallagrello e il più elevato contenuto <strong>di</strong> antociani e tannini nello Sciascinoso. L’analisi qualitativa <strong>di</strong> questecomponenti, me<strong>di</strong>ante LC/MS, ha messo in evidenza il <strong>di</strong>verso livello <strong>di</strong> espressione delle formemonoglucosi<strong>di</strong>che ed aciliche degli antocianicome anche il <strong>di</strong>verso grado <strong>di</strong> polimerizzazione dei tanninicondensati estratti dai vinaccioli in funzione delle cultivar.Le molecole aromatiche comuni a tutte le uve analizzate sono state solo il limonene, il 4-carene ed il linalolo,mentre l’a-pinene, il mircene, il 3-carene, il mentolo, l’α-terpineolo, il geraniolo, il β- demascenone,l’isobornilacetato e l’α-ionone sono strettamente correlate alla cv.SISTAL - SOCIETA’ ITALIANA DI SCIENZE E TECNOLOGIE ALIMENTARIDipartimento <strong>di</strong> Scienze e Tecnologie Agroalimentari, Università degli Stu<strong>di</strong> della TusciaVia San Camillo de Lellis, 01100 ViterboTel.: 0761- 35 74 94/7 , Fax: 0761- 35 74 98, e-mail: mmoresi@unitus.it277
