The raw material for alcohol production is a variety of plant materials, which contain sufficient amounts of digestible sugars or other carbohydrates that can be saccharified. Dahlias are tuberous plants of the Asteraceae family with a quick and powerful growth and a long vegetation period. The study of the chemical composition of dahlia tubers is of undoubted interest in terms of practical health care. Dahlia tubers are the main raw material for obtaining inulin, which has a wide range of pharmacological action. The vegetative (aboveground) part of dahlia has been an object of research. The purpose of this study has been to study the chemical composition of raw alcohol, obtained from the dahlia tubers. For this purpose, the chemical composition of the tuber of dahlia plants belonging to the Compositae family has been studied. It has been found that the tubers of dahlia contain a large amount of biologically active substances: protein, coumarin, polyphenol, pectin and inulin. Dry alcoholic yeast (TC BY 100104781.010-2005 dried alcoholic yeast Saccharomyces cerevisiae produced in Belarus) has been used as yeast. The fermentation process has taken place at the room temperature for 2-3 weeks. After 2 weeks it has been filtered, the quantity of wort has been measured and distilled. The chemical composition of the raw alcohol, obtained from dahlia tubers has been identified on an Agilent 7890A/5975C chromato-mass spectrometer.
