AbstractAbstract
[en] The objective of this work was to verify the influence of gamma radiation on the aging of sugarcane spirit. Samples of sugarcane spirit (cachaca ) were irradiated in a Gammabeam Cobalt-60 source with doses between 0 (control) and 300 Gy, with 50 Gy increasing. The irradiated samples were offered to 5 expert judges for sensorial tests using the comparison: irradiated versus control. The chemical volatile components of the irradiated spirit were determined using a gas chromatograph. Sensorial tests elected the dose of 150 Gy as the best for sugarcane spirit irradiation based on its flavour and bouquet. These sensorial characteristics were due to the chemical changes observed in esters, aldehydes and higher alcohol's concentrations. The samples irradiated with 250 and 300 Gy developed a bitter taste and an 'oxidized' flavour. A second experiment was carried out using single and twice-distilled sugarcane spirit, normal aged in oak barrels or not, or added with oak extract. Samples were irradiated with the dose of 150 Gy and scored by the same sensorial analysis methodology. All irradiated samples had their flavour improved. The irradiation of the non-maturated twice-distilled sugarcane spirit produced a flavour compared to spirits maturated during one year of normal aging. (author)
