摘要：It was verified the possibility to reduce a number of parameters necessary for the time-intensity-analysis in the sensorial characteristics of aged sugar cane spirits (“cachaça”). It was made a statistical study of all possible parameters, which were submitted to stepwise discriminant and regression analysis. It was sampled aged “cachaças” in oak barrels at zero, 12, 24, 36 and 48 months and six commercial brands, being three aged and three not, for the evaluation of sweetness, aggressive alcoholic taste and wood taste. The parameters obtained from each curve were: time to reach the maximal intensity (TImax), time in which the maximal intensity begins to decline (Td), duration time of the maximal intensity (Plato), total area under the curve (Area), total duration time of incentive (Ttot) e maximal intensity noticed (Imax). The results suggested that the parameters Imax and Plato could be eliminated in the time-intensity analysis of the sweet taste and wood taste, respectively without changing the final results of the analysis.
