6A.1 Introduction


Together with proteins and peptides, amino acids constitute the main components


of the nitrogenous fraction of musts and wines. They are also the most studied and


best known nitrogenated components in wines. They serve as nutrients for yeasts


in alcoholic fermentation and can also bemetabolised by the lactic acid bacteria


responsible for the process of malolactic fermentation. The concentration and com-


position of amino acids in wines and musts can also have an important effect on the


aromatic complexity of wines (Bisson 1991; Rapp and Versini 1991). To obtain


a good knowledge of the amino acid composition of a particular must or wine,


depending on the grape variety, technological procedure or critical winemaking


factors and steps, amino acid analysis is very important and has received special


attention in the literature (Moreno-Arribas et al. 1998; Hern ́andez-Orte et al. 2003).


Amines are widely occurring compounds in nature, containing one or more


organic substituent bonded to a nitrogen atom. Biogenic amines are low molecular
