Resumo
Contrary to the ethanol industrial production, the quality and composition of
sugar cane as raw material for the production of alembic cachaça have until
now not been completely addressed. This work evaluated the influence of five
different sugarcane cultivars and degree of maturation over the physicochemical
composition of cachaça produced under strict controlled conditions.
Three harvest seasons were used in order to obtain different stages of maturation.
The sugarcane quality was assessed by the juice brix, sugarcane POL, reducing
sugars, and purity. The cultivars quality did not differ within each
harvest stage. However, significant quality differences were observed among
sugarcane harvested in June and the other harvest months, particularly on
reducing sugar content. This indicates different stages of sugarcane maturation.
The 45 samples of cachaça produced from those sugarcanes were submitted
to physicochemical and gas chromatography/mass spectrometry
(GC/MS) qualitative analysis. The GC/MS composition pattern showed that
the type of cultivar did not alter the composition of the cachaça at the same
harvest stage. Otherwise, the production of acetic acid, ethyl lactate and nbutyl
alcohol was higher in the first harvest (June) when compared to the others.
The results from sugar cane quality and GC/MS when submitted to principal
component analysis (PCA) showed consistently the separation between
the groups of cachaça produced in the three seasons, indicating the influence
of sugarcane ripening over the cachaça composition.
