I.V. Oseledtseva, T.I. Guguchkina, N.M. Ageeva
Annotation

Higher alcohols are essential parts of cognac flavor. They produced from carbohydrates as well as a result of the deamination or transamination of amino acids followed by decarboxylation and reduction keto aldehydes in alcohol fermentation process, so the concentration of certain groups of compounds of higher alcohols depends on the content of particular amino acids. Conducted research aimed at determining the degree of influence of alanine and valine introduced in must at the stage of fermentation, to change the ratio of the concentration of isoamyl and isobutyl alcohols during the fermentation of grape must yeast genus Saccharomyces. It was established experimentally that the introduction of the wort before fermentation valine and alanine increases the concentration of isobutyl, isoamyl alcohol, and propyl alcohol. When increasing the insertion amount of alanine portion formed of isobutanol in comparison with synthesized by isoamyl increases, however even with the introduction of alanine in the amount of 100 mg/dm3 ratio izoamilol/isobutanol is 3,2 to 4,8. With the introduction of valine as the share of introduced amino acid ratio izoamilol/isobutanol and decreases when you make 10 mg/dm3 is 2,9–3,8, but when you make 100 mg/dm3 – 1,9–2,2. It was established experimentally that in the case of strains for fermentation Oenoform C2 and Actiflore cerevisiae decrease the concentration of 2-phenylethanol in making both the analyzed amino acids in concentrations exceeding 100 mg/dm3. At the same time a significant impact on the change in concentrations of butanol-1 and hexanol-1 introduction of alanine and valine was not there. The obtained results can be used as additional identifying indicator for quality control and to detect signs of falsification cognac.
