Multiple discriminant analysis in the analytical differentiation of Venetian white wines. 4. Application to several vintage years and comparison with the k nearest-neighbor classification

Chemometric Characterization and Classification of Five Venetian White Wines

“…In previous papers we showed that multivariate statistical methods can be applied successfully to the chemometric characterization and classification of typical wines (Moret et al, 1980(Moret et al, , 1983(Moret et al, , 1984a(Moret et al, -c, 1986(Moret et al, , 1988; Scarponi et al, 1982Scarponi et al, ,1990. Five typical Venetian white wines (from the Veneto and Friuli regions of Italy, vintages from 1977 to 1983) were investigated; a few classical determinations, the concentration of several inorganic ions, and a series of aroma compounds were considered as chemical analytical variables.…”

Evaluation of headspace volatiles of cabernet sauvignon wines sampled by an on-column method

“…For example, trace elements have been used to classify wines according to type or region in several studies (Kwan et al, 1979; Maarse et al, 1987). Trace elements plus other wine components such as amino acids, organic acids, pigments, and flavonoids were used by other researchers (Etievant and Schlich, 1988a,b;Etievant, 1989; Forina et al, 1986;Moret et al, 1984a; Voet et al, 1984).…”

Square-wave anodic-stripping voltammetric determination of Cd, Pb and Cu in wine: Set-up and optimization of sample pre-treatment and instrumental parameters

“…Trace metals (and trace elements in general) in wine are determined not only to guarantee wine quality, typicality and authenticity (especially using chemometric methods to identify the type of wine and/or its geographic origin) and in particular against fraud or adulteration [3][4][5][6][7][8][9][10], but also to evaluate possible contamination derived from environmental pollution [1,11,12], to monitor the content of substances added during the wine making process, and to demonstrate compliance with legal limits, especially for export purposes [2,13], as well as to assess the contributions the voltammetry (ASV), in differential pulse mode (DPASV) and linear sweep mode (LSASV) [17,19,22,23,27,36,[51][52][53][54][55][56], and potentiometric stripping analysis (PSA) [12,20,21,42,[56][57][58][59][60]. To our knowledge, square-wave anodic-stripping voltammetry (SWASV), i.e.…”
