The main quantity of the produced ethyl alcohol is consumed by the food industry as a basis for the manufacture of alcoholic beverages, pharmaceuticals and other alcohol-containing products. In addition to food production, ethyl alcohol is widely used in medicine, perfumery, and other industries. The actual problem of alcohol production is finding ways to reduce the cost of raw materials and energy resources but still getting the world quality standard of alcohol. The best solution to the problem is to improve the technological schemes of rectification plants. For this, information was updated on modern schemes and methods for obtaining rectified alcohol. During the research, and information search was carried out in Russian and English language literary sources. A comparative analysis of books, manuals and articles on this topic was carried out, as well as the GOSTs requirements for rectification columns over the past few years were studied. The main components of rectification units were considered: contact devices (types of plate and packed devices) and rectification columns (applied pressure: atmospheric, vacuum, under a certain pressure; and their total number).Progressive schemes used in modern alcohol production in Russia and abroad (Ukraine, USA, France, Finland) were considered. Based on the received data, the following conclusions were formulated: the most effective types of contact devices are sieve and valve trays, among the packing there are Raschig rings, a promising type of columns is disc-type, the most popular scheme for the operation of a rectification plant is a combination of work under pressure and vacuum.

The manufacturing process, the source (raw materials), and primary packaging materials dictate requirements for the quality of ethyl alcohol used in the pharmaceutical industry.The aim of the paper was to analyse how the quality of ethyl alcohol used as a component of medicinal products depends on the starting materials, production method and technology, intended use, and the choice of the primary packaging. The paper analyses available information on ethyl alcohol quality and summarises data on potential impurities associated with the ethyl alcohol production technology and the starting materials used. It was established that Russian manufacturers mainly use grain crops (wheat and rye), as well as molasses—a by-product of the sugar industry, as raw materials. The paper addresses the process of improving the quality standards for ethyl alcohol from a historical perspective. A comparative study of the requirements of the Russian and the world’s leading pharmacopoeias for the pharmaceutical substance—ethyl alcohol 95%, 96% demonstrated the need to include identification by IR-spectrometry and impurity control by UV absorbance into the respective monograph of the State Pharmacopoeia of the Russian Federation. The authors formulated requirements for the choice of packaging material for ethyl alcohol, which will not affect its quality during transportation and storage.

The market value of alcohol production reaches 500 rubles per 1 decaliter (at a cost of up to 430 rubles per 1 decaliter), which does not allow it to be used effectively for purposes other than alcohol beverages. To successfully implement this ethanoll for the needs of the chemical and fuel industry it is necessary to achieve a market value of up to 300 rubles per 1 decaliter (with a cost of 250 rubles per 1 decaliter). To achieve such indicators, studies were carried out on the production of alcohol from starch-containing secondary raw materials of grain complex processing for gluten, starch, syrups, amino acids and organic acids. Samples of starch milk and wheat bran were used as secondary raw materials. As a result, the ratio of starch milk and bran was selected, which allows obtaining a normative yield of alcohol up to 66.3 decaliter / ton of conventional starch. The resulting bard was similar in terms of indicators from the grain, which makes it possible to treat stillage to dried fodder using the same enrgysave equipment. To increase the value of this food, it was enriched with protein by cultivation of fodder yeast. As a result, a fodder product was obtained, corresponding to GOST R 55301-2012 "Yeast fodder from a cereal bard". Based on the conducted studies, a technology was developed for processing a mixture of starch milk and bran in ethyl alcohol and a protein feed product. The technical and economic analysis of the developed technology demonstrates efficiency of secondary raw material using for production of ethyl alcohol and protein fodder.

The global trend to raise awareness of hygiene and prevent the spread of infections is increasing the demand for antiseptics. In 2019, the European antiseptic market was estimated at 2.33 billion dollars. and by 2024 will reach 3.2 billion and the North American market of antiseptics amounted to 1.6 billion dollars. and by 2024 will reach 2.17 billion dollars. In 2019, the market for antiseptics in Ukraine was approximately 4,000 tons. Development of the domestic market of antiseptics, which consists of two stages – until early 2020, when demand was stable (limited by the B2B market and small antiseptics for personal use) and after early 2020 – a sharp increase in the market due to the emergence of coronavirus. Against the background of the coronavirus and quarantine pandemic in Ukraine there was a sharp jump in demand for antiseptics and their shortage, which was caused by two main factors: the bureaucratic barrier and shortage of raw materials (annual decline in ethyl alcohol production (the main component of antiseptics) ranged from 6 to 15 %%). Analysis of the data of the Compendium on 01.09.2020 allowed to analyze the registered 52 trade names of antiseptics and disinfectants. The domestic market is satisfied with the products of local pharmaceutical plants (Antiseptol H (Antiseptol H) 100 ml, LLC «FP Zdorovya»; Ethyl alcohol 96% 100 ml (Ethyl alcohol 96%), LLC «FP Zdorovya»). A study of the price range for antiseptics of the group «D08 – antiseptics and disinfectants» found that traditionally the prices of domestic manufacturers are much lower than foreign – prices ranged from 03-45 UAH. up to UAH 789-12. and for foreign – from 10-25 UAH. up to 1100-35 hryvnias. It was found that at the time of analysis from the subgroup «D08A X08 Ethanol» 38 (73%) of registered antiseptics are in circulation in the pharmaceutical market of the country, and 14 (27%) are absent. As a result of the legal regulation of antiseptics on businesses that are also producers of alcohol, now it has the right to produce and sell antiseptics under license for the production and wholesale of alcohol. The development of antiseptic production was considered on the example of the domestic manufacturer LLC «Biofuel and Energy Company», which during the crisis established the production and wholesale of «Hygienic detergent BIOSEPT». The problem of development of antiseptic production in Ukraine is relevant today in connection with the spread of COVID-19 in the world, the prevention of which is aimed at compliance with sanitary requirements with the use of antiseptics and disinfectants

The topicality. Requirements for the quality of ethyl alcohol produced for further use in the production of alcoholic beverages are constantly increasing. This is due to the growing competition of producers of alcoholic beverages (improving the range and quality of products) and the revision of standards for products. New directions in the alcohol technology development require increasing the dry matter concentrations of the wort; fermentation at elevated temperatures and concentrations of alcohol in the brew; ensuring the reduction of the cost of alcohol by saving raw materials and energy resources. In such conditions, highly productive breeds of yeast with increased osmophilicity, thermotolerance and fermentation activity are required. Research related to the search for new strains producers of ethyl alcohol, and the technology development for highly concentrated mash from grain raw materials are relevant issues for the alcohol industry. Purpose and methods. Investigation of the alcoholic yeast races influence on the synthesis of metabolites during fermentation of highly concentrated wort from grain raw materials. For research methods common to the alcohol and alcoholic beverages have been used. Results. The influence of races of alcoholic yeast on the quality indicators of alcohol has been studied. It was found that the selected race of yeast S. cerevisiae DO-16 in the process of life synthesizes significantly fewer side metabolites compared to other studied races DO-11, K-81 and XII. The use of the selected race of S. cerevisiae DO-16 makes it possible to ferment highly concentrated wort from grain raw materials. It has been experimentally proved that at a concentration of DM concentration of the wort 28 %, the selected osmophilic strain of the yeast S. cerevisiae DO-16 provides regulated indicators of the hydrocarbon composition of mature brews and synthesizes up to 14.40 % vol. alcohol, respectively. To improve the qualitative sensory characteristics of ethanol, the possibility of metabolically adjusting the synthesis of volatile alcohol impurities using different races of alcoholic yeast was investigated. Conclusions and discussions. Scientific novelty lies in the selection race for the yeast fermentation of corn mash highly concentrated with reduced alcohol content related impurities. The influence of yeast race on the formation of alcohol metabolites has been studied. The practical significance of the obtained results lies in the industrial implementation of the selected race of alcoholic yeast for fermentation of highly concentrated wort from grain raw materials. Prospects for further research are the possibility of influencing the quality of alcohol as a raw material for high-quality alcoholic beverages. During the fermentation of wort from grain raw materials, the qualitative and quantitative composition of volatile impurities of alcohol largely depends on the race of alcoholic yeast. The results of research on the biosynthesis of volatile impurities of alcohol allow you to adjust the quality of alcohol for the production of high quality alcoholic beverages.

Uncoordinated carbon-nitrogen ratio in raw materials will lead to excessive contents of higher alcohols in alcoholic beverages. The effect of GAT1 gene, the GATA transcription activator, on higher alcohol biosynthesis was investigated to clarify the mechanism of Saccharomyces cerevisiae regulating higher alcohol metabolism under high concentrations of free amino nitrogen (FAN). The availability of FAN by strain SDT1K with a GAT1 double-copy deletion was 28.31% lower than that of parent strain S17, and the yield of higher alcohols was 33.91% lower. The transcript levels of the downstream target genes of GAT1 and higher alcohol production in the double-copy deletion mutant suggested that a part of the effect of GAT1 deletion on higher alcohol production was the downregulation of GAP1, ARO9, and ARO10. This study shows that GATA factors can effectively regulate the metabolism of higher alcohols in S. cerevisiae and provides valuable insights into higher alcohol biosynthesis, showing great significance for the wheat beer industry.

An actual problem of the alcohol industry development is the expansion of the raw material base through the use of new, cheaper types of carbohydrate sources. Recently, glucose-fructose syrup has been of increasing interest to producers of ethanol. Among the producers of craft drinks, in particular rum-based drinks, cane molasses is in increasing demand. The article presents the technological aspects of the fermentation process of nonconventional sugar-containing raw materials on the example of glucose-fructose syrup and cane molasses in ethanol by different yeast strains. It is determined that glucose-fructose syrup and cane molasses are raw materials depleted of nitrogen, phosphorus and growth substances necessary for the yeast activity. To improve the technological properties of raw materials in the molasses, nitrogen, phosphorus nutrition and corn extract as a growth substance shall be added to a mash. Glucose-fructose syrup is of pH 3.68 and of acidity 0.12, which negatively affects the fermentation. It is established that in order to create optimal living conditions for yeast, it is necessary to add substances to the glucose-fructose syrup that will contribute to the safety of development and prevent the pH 3.5. It was determined that the alcohol yield from 1 ton of glucose-fructose syrup is 31.0 dal, from 1 ton of cane molasses is 24.0 dal on the yeast 46ED and 22 dal on the TegaYeast without the use of growth substances and vitamins necessary for the reproduction of yeast biomass. Under conditions of improving the technological properties of the mash from the glucose-fructose syrup and cane molasses by adding biologically active substances promoting the synthesis of yeast biomass, the ethanol content in the fermented mashes increases up to 11.9 12% vol.

Background: The requirement of an alternative clean energy source is increasing with the elevating energy demand of modern age. Bioethanol is considered as an excellent candidate to satiate this demand.Methods:Yeast isolates were used for the production of bioethanol using cellulosic vegetable wastes as substrate. Efficient bioconversion of lignocellulosic biomass into ethanol was achieved by the action of cellulolytic bacteria (Bacillus subtilis).  After proper isolation, identification and characterization of stress tolerances (thermo-, ethanol-, pH-, osmo- & sugar tolerance), optimization of physiochemical parameters for ethanol production by the yeast isolates was assessed. Very inexpensive and easily available raw materials (vegetable peels) were used as fermentation media. Fermentation was optimized with respect to temperature, reducing sugar concentration and pH.Results:It was observed that temperatures of 30°C and pH 6.0 were optimum for fermentation with a maximum yield of ethanol. The results indicated an overall increase in yields upon the pretreatment ofBacillus subtilis; maximum ethanol percentages for isolate SC1 obtained after 48-hour incubation under pretreated substrate was 14.17% in contrast to untreated media which yielded 6.21% after the same period. Isolate with the highest ethanol production capability was identified as members of the ethanol-producingSaccharomycesspecies after stress tolerance studies and biochemical characterization using Analytical Profile Index (API) ® 20C AUX and nitrate broth test. Introduction ofBacillus subtilisincreased the alcohol production rate from the fermentation of cellulosic materials.Conclusions:The study suggested that the kitchen waste can serve as an excellent raw material in ethanol fermentation.
