Abstract:
Differences among the low molecular weight phenolic content of different wine vinegars have been studied.
A method of continuous rotatory extraction and individual analysis by HPLC separation of phenolic compounds, worked out by the authors, has been applied to several different wine vinegar samples.
Important differences have been found as a function of the wine age and the method of elaboration used.
LDA has been applied to the differentiation of each kind of samples.
