THE RESEARCH OF THE PROCESS OF DISTILLATION OF FRUIT WINE MATERIAL WHEN RECEIVING SEA BUCKTHORN DISTILLATES
The results of the research of the process of distillation of fruit wine material of a sea buckthorn when receiving distillates for production of strong alcoholic beverages were presented. The process of distillation of sea buckthorn wine materials was studied; the method of gas chromatography experimentally determined the distribution of flying components at repeated distillation of sea buckthorn raw alcohol. The optimum conditions for receiving qualitative sea buckthorn distillates providing the use of double distillation were established. Comparative analyses of sea buckthorn distillates with using three varieties of a sea buckthorn selected in Scientific Research Institute of Gardening of Siberia named after M.A. Lisavenko RAAS were carried out (Barnaul, Altai Region). The main marker connections allowing estimating objectively the quality of the sea buckthorn distillates and strong alcoholic drinks received on their basis were established. The main aromatic components present at sea buckthorn distillates were defined. It was proved that at the selection of average fraction of distillate with a volume fraction of ethyl alcohol of 68.5-74.5 % it contains the main aromatic components responsible for the formation of characteristic fruit aroma of a sea buckthorn that was important for the formation of touch properties of a hard liquor on the basis of the sea buckthorn growing on the territory of Altai Region. The results presented in the study are fundamental for the development pilot and semi-plants for scaling the process of distillation when receiving new types of hard alcoholic beverages with using industrial plantings of a sea buckthorn of Altai Region as a raw source. The obtained data on the content in sea buckthorn distillates of ionon (products of degradation of carotinoids) can be used further for the development of techniques of identification and the assessment the authenticity of the distillates and strong drinks received on the basis of a sea buckthorn.
