In the present work the composition of apple liqueurs has been analyse
d, since the consumption of these beverages in Spain has increased dur
ing the last years. Twenty-five samples, belonging to the most represe
ntative five brands of the Spanish market have been analysed. The foll
owing determinations were carried out: alcoholic grade, total acidity,
methanol, furfurol, dry extract, reducing sugars, sucrose, ash contac
t, macroelements (Na, K, Ca, Mg) and microelements (Cu, Fe, Mn, Zn). T
hese parameters enable the quality evaluation of these beverages and c
ontribute to their characterization with respect to the fruit used in
their elaboration. To complete the experimental study, a BMDP 7M discr
iminant statistical analysis has been applied to the results obtained.
The variables that best discriminate the groups have been determined
and all the samples have been classified and differentiated.
