On the territory of Krasnoyarsk Region there is a significant number of both wild and cultivated fruit and berry crops with a unique chemical composi- tion; one of them is Amelanchier rotundifolia. Amelanchier rotundifolia fruits are mainly used for domestic preparations; in industrial production of alcoholic beverages they have not been applied. The aim of the study was to investigate chemical composition of Amelanchier rotundifolia growing in Krasnoyarsk Region and develop the formulation of sweet tincture based on it. The collection of raw materials was made in Emelyanovsky district of Krasnoyarsk Region in the period of technological maturity (August). Chemical composition of Amelanchier rotundifolia has been stated. High con- tent of extractives (15.07 %) and sugars 10.83 % have been found. Received data testify about the presence of in fruits of Amelanchier rotundifoliaunchangible and important for the organism ele- ments, such as sodium (25.13 mg/kg), potassium (1602.42 mg/kg), aluminium (74.5 mg/kg) and oth- ers.The recipe of sweet liqueurs based on fruits of Amelanchier rotundifolia was developed, organo- leptic and physical-chemical indicators of the quali- ty of the product meeting the requirements of State Standard R 52192 "Alcoholic beverage products. General specifications” were defined. The composi- tion of the formulation of tincture included alcohol infusion of Amelanchier rotundifolia, citric acid, ethyl alcohol brand "Lux", water. Beverage strength was 20 %, the content of g/100 cm of total extract - 29.5, sugar - 28.0, acids in terms of citric acid - 0.3.
