Comparison between the volatile substances in spirits beverages distilled by two different initial materials of Prunus domestica “Stanley” in an industrial environment

Analysis of the chemical composition volatile substances in two distillates from Prunus domestica “Stanley” cultivated village Rumyantsevo, Lovech, Bulgaria. Production is an industrial environment, fermentation and distillation are carried out under equal conditions, but on different starting materials. One batch PDS-1 distilled fermented mash second PDS-2 juice. The apparatus equipped with a rectifying column 4 trays, as well water reflux condenser. Determination congeners both samples was done by gas chromatography principle OIV-MA-BS-14:2009. Methodology used for measuring alcohol content, cyanide derivatives, furfural total acidity according to requirements OIV. In methanol (1094.7 g/hL a.a.) almost 8% higher than (1015.8 a.a.), it found insignificant increase content PDS-2. Concerning esters, aldehydes alcohols amount PDS- 1 significantly PDS-2, respectively 203.06 g/hL, 14.2 484.6 hard particles, 8.6 267.9 produced
