VOLATILE COMPOUNDS IN CACHAÇAS OBTAINED FROM THREE SUGARCANE VARIETIES CULTIVATED UNDER THE MANAGEMENTS: ORGANIC, CONVENTIONAL AND WITHOUT FERTILIZATION

The volatile compounds present in cachaça can derive from the raw material used in the production of the beverage, from the fermentative process, from distillation or aging. The aim of the research was to evaluate the volatile compounds, in the cachaças from stills produced with different sugarcane varieties, under the organic and conventional managements. The varieties RB867515, RB962869 and RB85553 were cultivated in three distinct ways, planting without fertilization (OUTF); organic planting (ORGN) and conventional planting (CONV). The results showed that for the total esters, higher alcohols and coefficient of congeners present in the cachaça, the varieties and managements are dependent, unlike volatile acidity, total aldehydes, methyl alcohol and furfural. Therefore, the quality, origin and lineage of the sugarcane variety used for the production of cachaça were confirmed to influence the chemical concentrations of the volatile compounds of the beverage, modifying its chemical profile. It is worth reinforcing that none of the volatiles presented concentration above that allowed by the Brazilian legislation.
