Abstract
S. domestica are valuable plants which have been used for both nutritional purposes and in traditional medicine. Recent studies reveal that in the fruits of S. domestica the sugar content and total acidity is similar to quantities in apples (Malus spp.) and pears (Pyrus spp.). Despite the sufficient data obtained S. domestica is not yet so strongly represented in the production of distilled beverages. For the purpose of this study, we obtained beverages by means of three different methods - distillation of fermented juice (A), distillation of fermented crushed fruit mixture (B) and distillation of ethanol-water extract (C). The different fractions obtained during the distillation process were studied and correspondently used to determine the quantities of Alcohol, Esters, Aldehydes, Higher alcohols and Methanol. Concentration of Esters in the fractions is between 3688.0 mg/L to 29.0 mg/L. The quantity of Esters in fractions of Series A and B is three times higher than in Series C. Regarding the Aldehyde and Higher alcohols content is ten times higher in both A and B Series in comparison to Series C.
Highlights
Sorbus Domestica is a species belonging to genus Sorbus, spread mainly in Western, Central and Southern Europe, in Northwestern and Southwestern Africa
Some species of the genus Sorbus are grown for their fruits, and one of the economically valuable is S
The content of higher alcohols was determined by the Komarowski-Felenberg method, by measuring the intensity of a color compound formed by interaction with para-dimethyl amino benzaldehyde [5]
Summary
Sorbus Domestica is a species belonging to genus Sorbus, spread mainly in Western, Central and Southern Europe, in Northwestern and Southwestern Africa. Some species of the genus Sorbus are grown for their fruits, and one of the economically valuable is S. Domestica, which belongs to the subgenus Cormus [1]. These trees are very rare and endangered in many European countries, the fruits of S. domestica have been valued since Roman times. The fruits are 2-3 cm apple or pear shaped, with greenish to brownish color. The distillate beverages obtained from the fruits are highly valued due to their specific characteristics [2]
