| Tartalmi kivonat: | With the support of the National Research, Development and Innovation Fund, within the framework of the KMR-2 project, a research was carried out by WESSLING Hungary Kft. between 2013 and 2015, in connection with changing the distillation parameters of fruit spirits, among other things. Within the framework of the research, characteristic volatile components of different fruits (apples, pears, sour cherries, apricots and plums) were investigated. It was determined that, during distillation, the different components are transferred into the distillate according to typical distillation curves, so they can be grouped easily according to their propensity to be enriched in the vapor phase at the end of the vapor pipe in the heads, hearts or the tails phase. When analyzing sample fractions taken systematically during the distillation, a clear correlation could be demonstrated between the change in the partial condensation used in the distillation, the so-called dephlegmation degree, and the change in the relative volatility of the volatile components entering the distillate from the vapor phase during distillation. When the dephlegmation degree decreased, of the components analyzed, the relative volatility of methanol compared to ethanol decreased, while it increased for all other components analyzed, i. e., the concentration of the volatile components entering the distillate during the preparation of fruit spirits will be higher or, in other words, the fruity character will be more intense if the dephlegmation degree is lower. Given the results of the project, it becomes possible to influence the distillate composition consciously by changing the distillation parameters. |
