Abstract

The work shows the biological and nutritional value of Rubus, which grows in Azerbaijan. It was found that the highest content of sugars is the wild blackberry of the Rubus sanguineus Friv species (8.75±0.19%), while it contains little sucrose, glucose (from 3.10±0.12 to 4.87±0.16%) and fructose (from 3.08±0.28 to 3.40±0.09%) predominate. The content of the mass fraction of organic acids is greater in the species Rubus caucasicus forche (1.94±0.10%) than in the species Rubus caesius and Rubus sanguineus Friv (1.85±0.15 and 1.62±0.12%, respectively). The content of pectin substances in blackberries ranges from 0.26±0.01 to 0.30±0.04%, and the mass fraction of ash from 0.42±0.08 to 0.58±0.11%. In terms of vitamin C content, the species Rubus sanguineus Friv is superior (32.1±1.20 mg/100 g) to the species Rubus caesius and Rubus caucasicus forche (23.76±0.58 mg/100 g and 29.35±0.47 mg/100 g, respectively). In the polyphenol complex of blackberries of the species Rubus sanguineus Friv, Rubus caucasicus forche and Rubus caesius, catechins and anthocyanins are present with a clear predominance of the latter. The results of the studies show that the main indicators of the chemical composition of blackberries depend on the type of raw materials and on the soil-climatic and ecological-geographical conditions of the growing region. The biological and nutritional value of blackberries of various types allows us to consider them as an additional source of physiologically active substances and raw materials for the production of various soft drinks based on them, including tonic energy drinks.
