註釋Besides classical one-dimensional (1D) analyses, comprehensive two-dimensional (2D) chromatographic separation techniques with profiling approaches are powerful tools to gain a better understanding of viti- and vinicultural influences on wine aroma changes. Chemometric tools from the “omics” field allow wine quality aspects to be correlated with compositional data. In an example, profiles of volatiles obtained by 2D-GC (GC×GC) analysis were treated as fingerprints and studied by using multivariate statistics in order to discriminate between grape origin. Further (“comprehensive”) incorporation of analytical techniques (NMR and others; “analytonomics”) also extends compositional information for non-volatiles, eventually decoding the substantial background for wine quality.
