| Abstract:
The role presented by the phenolic compounds in the studies relating wine differentiation is more outstanding each time. The phenolic content of a wine will depend on a great number of factors: variety, fermentation techniques, aging process, etc. The purpose of this study is to know if we can also differentiate wines produced with different clones of the same grape variety, thanks to its polyphenolic content, in the particular case of grape variety called Palomino Fino. The phenolic compounds has been determined through liquid-liquid extraction continuous rotatory and a subsequent HPLC. The research has studied the polyphenolic profile which present various clones of the Palomino Fino variety on two points of its ellaboration process (end of fermentation and "deslío") with the purpose of knowing the basic differences which can exist between clones. The data obtained have been submitted to subsequents chemometrics studies using different statistical analysis techniques. | |
