Carotenoid compounds in wine grapes (Chardonnay, Merlot, Primitivo, Negroamaro) grown in Apulian region were investigated by chromatographic and spectrometric analyses. Cis-isomers of lutein and beta-carotene (9Z, 9'Z-lutein and 9Z-beta-carotene) and 5,6-epoxyxanthophylls were detected: 9'Z-neoxanthin, violaxanthin, and 5,6-epoxylutein. Moreover, zeaxanthin(More)
To determine a correlation between carotenoid precursors in grapes and norisoprenoid varietal aroma of wine, carotenoids were identified and quantified by HPLC-DAD-MS (ESI+) from four representative wine grape varieties of the Apulian region (Chardonnay, Merlot, Negroamaro, Primitivo) in two years of study (2006-2007), and C13-norisoprenoid aroma potential,(More)
This study aims to assess the effect of three wine grape varieties, three training systems and two bud loads on the Total Antioxidant Capacity (TAC) and polyphenolic composition of Southern Italy red wines produced, during two vintages. Overall, Primitivo, Malvasia nera of Brindisi-Lecce and Montepulciano as grape varieties, single Guyot (SG), single spur(More)
Metabolic profiles of 32 Negroamaro red wines were analysed using (1)H NMR spectroscopy and multivariate statistical analyses (Principal Component Analysis, PCA, and Orthogonal Partial Least Square Discriminant Analysis, OPLS-DA). Among winemaking technologies three were compared: ultrasounds (U; 12 samples), cryomaceration using dry ice (C; 12 samples) and(More)
This extended abstract explores the relationship between Project Management and the internationally recognized models/standard for process assessment and improvements CMMI (Capability Maturity Model Integration) and SPICE (ISO/IEC 15504). It provides initially an overview and some historical background on concepts and terminology related to the so called(More)
RATIONALE Due to their health benefits, there is growing interest in the production and use of carotenoids from natural sources, e.g. microalgae. To date, only Haematococcus pluvialis and Dunaliella, that accumulate, respectively, astaxanthin and β-carotene in large quantities, are grown commercially. However, interest is also being focused on other(More)
Negroamaro is an autochthonous wine grape variety of Southern Italy, which is becoming very important for the Italian wine market. The wine aroma is primary affected by the chemical composition of grapes, which can be influenced also by agronomic practices such as soil management. In this study, the free and bound aroma characterization was performed by gas(More)
This paper presents the results of the ASAI (Automotive SPICE Assessors and Improvers) working group. The aim of the ASAI is to address open issues in the real application of the standard Automotive SPICE in the automotive industry. The outcomes of the ASAI activities are a set of guidelines on how some relevant open issues (expressed by means of questions)(More)
