Abstract An automated gas-liquid chromatographic (GLC) system, including automatic sampling, calculation, and reporting, was applied to the analysis of 7 samples representing 4 types of alcoholic beverages. Using a GLC column packed with glycerol-1,2,6-hexanetriol on Gas-Chrom R and a flame ionization detector, the following compounds were separated and quantitatively measured: acetaldehyde, ethyl acetate, propanol, isobutanol, active amyl alcohol, and isoamyl alcohol. Acetal is resolved from the other compounds.

Рассмотрена возможность повышения качества виноматериалов с помощью подбора штамма винных дрожжей. Исследовано 12 штаммов дрожжей различных производителей и ценовых категорий. Виноградное сусло получали из белого винограда технического сорта Цитронный Магарача, выращенного в Самарской области. Качество винограда соответствовало требованиям ГОСТ 31782–2012. Переработку винограда вели в полупромышленных условиях по «белому» способу. Дозировка дрожжей составляла 0,2 г/л. Брожение сусла и хранение полученных виноматериалов осуществляли при температуре 14–15°С. Показатели качества полученных сухих столовых виноматериалов удовлетворяли требованиям ГОСТ 32030–2013 по всем основным показателям. Из виноматериалов путем прямой перегонки получены винные дистилляты и подвергнуты газохроматографическому анализу. По содержанию летучих компонентов – метанола, сивушных масел, сложных эфиров, ацетальдегида, бензальдегида, кетонов все образцы соответствовали требованиям ГОСТ 31493–2012. Установлено, что по скорости сбраживания, флокулирующей способности и продуцированию летучих компонентов наилучшим для выбранного сорта винограда является штамм дрожжей Vitilevure DV10 (Danstar Ferment AG, Дания). Possibility of improvement of quality of wine materials by means of selection of a necessary strain of wine yeast is considered. 12 yeast strains of different producers and price categories were investigated. The grape mash was received from white grapes of a technical grade Tsitronnyy Magaracha who is grown up in the Samara region. The quality of grapes conformed to requirements of GOST 31782–2012. Processing of grapes was conducted in semi-industrial conditions on a white way. The dosage of yeast was 0,2 g/l. Fermentation of a mash and storage of the received wine materials carried out at a temperature of 14–15°C. Indicators of quality of the received dry table wine materials met requirements of GOST 32030–2013 for all key indicators of quality. From wine materials by direct distillation wine distillates was obtained and subjected to gas chromatographic analysis. According to the content of volatile components-methanol, fusel oils, esters, acetaldehyde, benzaldehyde, ketones, all samples met the requirements of GOST 31493–2012. It was found that the rate of fermentation, flocculating ability and production of volatile components is best for the selected grape variety strain Vitilevure DV10 (Danstar Ferment AG, Denmark).

In this study, by-products from alcohol production were examined in terms of their potential application as external carbon sources for enhancing denitrification in biological nutrient removal systems. Three types of batch tests were used to compare the effects of the distillery by-products, such as fusel oil, syrup and reject water, on the non-acclimated activated sludge. Much higher nitrate utilization rates (NURs) were observed for the latter two carbon sources. In the conventional NUR measurements (one-phase experiments), the observed NURs with syrup and reject water were 3.2–3.3 g N/(kg VSS h) compared with 1.0 g N/(kg VSS h) obtained for fusel oils from two different distilleries. When the carbon sources were added at the beginning of the anoxic phase preceded by an anaerobic phase (two-phase experiments), the NURs were 4.2 g N/(kg VSS h) (syrup and reject water) and 2.4–2.7 g N/(kg VSS h) (fusel oils). The heterotrophic yield coefficient, determined based on the conventional OUR measurements, varied in a relatively narrow range (0.72–0.79 g COD/g COD) for all the examined carbon sources. Due to advantageous composition (much higher COD concentrations and COD/N ratios), fusel is a preferred carbon source for practical handling in full-scale wastewater treatment plants.
