摘要: BACKGROUND: Śliwowica Łącka is a strong, distilled, home-made plum brandy produced in submontane region of Poland. The aim the present study was to determine chemical composition this alcoholic beverage (samples from years 2001–2004) and compare it with that other brandies. Gas chromatography spectrophotometry methods were used detect major volatile components. RESULTS: Home-made Polish brandies generally contained more ethanol (64.7–72.5% v/v), methanol (5.59–8.74 g L−1100°) butanol (32–335 mg less isobutanol (406–491 L−1100°), pentanol (4.3–14.9 2-phenylethanol (61–68 than samples. amyl alcohols/1-propanol isobutanol/1-propanol ratios might be as indices distinguish spontaneously fermented those by monoculture. Statistically significant differences (P < 0.01) found sensory characteristics examined. Total scores ranged between 12.0 14.3, while Slovakian Slivovica received highest score (16.7). CONCLUSION: results showed Łącko area are characterised similar original mainly spontaneous fermentation well traditional production technology. Copyright © 2007 Society Chemical Industry
