| Summary: | It is well
-
known that during aging, several compounds are extracted from the oak barrels that have a positive influence on
the sensory characteristics of the rum. The sensory improvement is the re
sult of many transformations that take place among
the rum distillate components and those of the oak wood. These involve reactions between constituents of the spirit,
reactions between substances extracted from the wood and their oxidation, and reactions
between the original compounds,
extracted compounds, and those formed previously. For the aging of Cuban rum in oak barrels it has been necessary to
import it and there are lots of barrels with the origin known, but others unknown. This paper analyzed the
profile of oak
volatile compounds of three lots coming from American, former Soviet Union and Yugoslavia and three lots of unknown
origin. With maceration of oak chips with ethanol 55% v/v, extraction with dichloromethane and gas chromatography

spectr
ometry analysis, 126 volatiles compounds were determined including phenol derivatives (40), esters (28), acids (17),
alcohols (11), terpenes (10), aldehydes and ketones (8), acetals (4), furanic derivatives (3), lactones (3), and others with
different func
tions (2). A total of 70 compounds showed statistical differences and the principal component and discriminant
analysis classified the six lots in four groups: American, former Soviet Union and former Yugoslavia origin in different
groups, two unknown orig
in lots in the same group with Yugoslavian lot and a remaining lot of unknown origin in a
separate group |
