Introduction. The purpose of the publication is to assess the quality and to usage of natural charcoal of activated charcoal by physical and chemical indicators for alcoholic beverage production - for the purification of water-alcohol mixtures from impurities in the technology of vodka. Materials and methods. Activated charcoal - as a raw material for the purification of water-alcohol mixtures in the technology of vodkas. Methods of research: adsorption activity by iodine; adsorption activity by acetic acid; adsorption activity by methylene blue; total volume of pores in water; bulk density of activated carbon; fractional composition; mass of ash; bulk iron; bulk moisture content; abrasion strength. Results and discussion. Activated charcoal of plant origin BAUA, BAU-A-LVZ, BAU-A-Ag, MeKS, KAU-A, KDS-A according to the complex of indicators does not fully meet the high requirements of alcoholic beverage production. The active charcoal grades BAU-A have the standard values of indicators: adsorption activity by iodine - 62%; adsorption activity by acetic acid - 64 ml; adsorption activity by methylene blue - 129 mg/g; total pore volume by water - 1.72 cm3/g; bulk density - 215 g/dm3; mass fraction of the balance on a sieve with a linen: - 36 - 1.6%; - 10 - 98%; on the pallet - 0.4%; mass of ash - 4.7%; mass fraction of water soluble ash - 1.64%; mass fraction of iron - 0,12%; mass moisture content - 3.8%; abrasion resistance - 52.8%. To expand the range of values of indicators, it is necessary to create different combinations based on the BAU-A grades of coal or their modifications BAU-A-LVZ, BAU-A-Ag together with activated charcoal stone (MeKS), coconut (KAU-A) and anthracite (KDS-A). Activated charcoal of the mark MeKS in relation to BAU-A has higher values: adsorption activity by iodine by 32%; adsorption activity by acetic acid by 45.3%; adsorption activity by methylene blue at 52.7%; bulk density at 62.4%; tensile strength at 37.3%. In relation to BAU-A, activated charcoal MeKS has lower values: the total volume of pore water by -9.6%; mass of the remainder on a sieve with a linen: - 36 on -1.5%; - 10 at -7.6%; on a pallet of 9.1%; mass of ash at -1.1%; a mass of water-soluble ash -0.4%; bulk of iron by 0.1%; mass moisture content -0.6%. At the same time low indicators of one activated carbon can be offset by high indicators of other coal. Conclusion. Creation of combined activated charcoal with optimized parameters (increased durability, high adsorption and catalytic properties, developed porous structure) will allow to meet the high requirements of alcoholic beverage production and to more actively absorb organic impurities, improving the organoleptic parameters of vodkas.
