AbstractAbstract
[en] Propolis is a natural product from vegetable origin, but, this substance, in general, is collected in the beehives. This product is largely known because its heath benefit attributed to its biological properties. On the other hand, Brazilian sugarcane spirit, 'cachaca', is an interesting alcoholic beverage with an increasing importance in the segment in many markets in the world. Therefore, was evaluating the addition of the propolis into cachaca and the effect of ionizing radiation on propolis compounds with biological properties. Samples of cachaca with propolis used in irradiation experiments were prepared from cachaca (40 deg GL) composed with propolis (0.1%). Eight treatments, with four repetitions each, were considered in this study. Three doses of ionizing energy from electron beam and gamma radiation from 60Co were applied on the cachaca samples, i.e. 0.5, 1.0, and 2.0 kGy, with the goal to accelerate the aging time of the cachaca. The sugarcane spirits samples were storage during two periods (immediately after the radiation treatment and 30 months after the treatments) and their flavonoids contents were analyzed. Flavonoids contents in sugarcane spirit were statistically different between both storage time. The samples of cachaca treated with electron beam at 2.0 kGy presented the highest reduction in flavonoids contents, approximately 30.0 % in relation to the first analysis time. In conclusion, the time of storage to promote reduction on the flavonoids contents and the ionizing radiation also promoted reduction on the contents of these compounds, mainly in the first period of storage.
