“…The content and composition of the anthocyanins complex of berries skin were determined by HPLC. Sample preparation and analysis were performed in accordance by method described in [13]. A Shimadzu LC20 Prominence HPLC system (Japan) equipped with a Nucleosil C18AB column (Macherey -Nagel, Germany) 250 mm long, 2.0 mm in diameter, filled with a reversed-phase sorbent (particle size 5 μm, porosity 100 Å) and a spectrophotometric detector with diode matrix was used.…”

“…The closest precursors of anthocyanins are flavonons (monoglucosides of cyanidin and delphinidin are primarily formed); their further modification by adding a methyl group leads to the formation of monoglucosides of peonidin, petunidin and malvidin [9,10]. The level of sugars required to start anthocyanins synthesis and anthocyanin complex formation are determined by the species and cultivar of grapes: Vitis vinifera at the stage of maturity is characterized by a prevalence of malvidin-3-O-β-D-glucoside and its derivatives, which are the final metabolites of the chain of transformation of anthocyanin compounds [11,12,13,14,15].…”

This article is aimed at identifying the relationship between the territories agro-ecological conditions and the anthocyanins complex formation of grapes, which determines the quality and biological value of red wines. Using HPLC, the anthocyanins complex of 'Cabernet Sauvignon' cultivar from 6 industrial vineyards, located in three natural regions of Crimea, was studied. The agro-climatic resources of vineyards were assessed using the methods of geoinformation and mathematical modeling. It was detected that according to parameters of heat and moisture supply vineyards discriminated with Wilks L. = 0.007; α<0.00001. The direct correlation (r = 0.88-0.95) was identified between growing degree days above 10 °C, growing degree days above 20 °C, Winkler index, average growing season temperature and the rate of monoglucosides of malvidin and its derivatives in anthocyanins complex of berries; the inverse correlation – between the same agroecological indexes and the rate of cyanidin, petunidin and their derivatives. The similarity (Ed = 2.79-2.98) of anthocyanins complex of grapes from Villino v., Uglovoe v. and Yalta t. located in the western foothill-coastal and south coast regions was discovered. The highest content of anthocyanins was found in grapes from Privetnoe v. (5487 ± 384 mg kg-1), the smallest - from Solnechnaya Dolina v. (2154 ± 129 mg kg-1) located in the same natural region. The results obtained indicate the need for a "point" assessment of the agro-ecological resources for creation of industrial vineyards.

“…The concentration of phenolic substances was determined using the Folin-Ciocalteu reagent, phenolic maturity -Glories method [19,20]. The study of the polyphenol oxidase (PPfO) activity and the content of SO2-binding components were carried out in freshly squeezed juice obtained by manual pressing of the whole berries.…”

Influence of the organic farming system on the composition of Bastardo Magarachskiy grape cultivar as a raw material for production of wines

Studies on the effectiveness of applying the scheme for organic processing of grape cultivar Bastardo Magarachskiy in comparison with the traditional scheme of protection against the powdery mildew on the background of its strong progression were conducted. It was established, that the organic protection scheme is not inferior to the traditional processing scheme in its effectiveness and influence on the composition of grape berries. The biological effectiveness of the organic protection scheme in vineyards averaged 78.3%. There is no significant difference in grapes obtained in the traditional and organic processing schemes by the mass of the bunch, the concentration of sugars and titratable acids in the berry. The use of biological products in foliar treatment had such beneficial effect on the formation of the phenolic complex of berries as the increase in supply of phenolic substances and growth of phenolic maturity. The use of organic protection scheme against powdery mildew led to a decrease in the concentration of pyruvic acid in juice by 2.5 times on average, compared with the traditional one, and an increase (in comparison with the traditional and control) by 1.4 −1.6 times of the concentration of α-ketoglutaric acid. The studied treatment regimens did not affect the concentration of aldehydes.

“…The basis of the quality of wine is established at the stage of grape ripening and is formed under the influence of physiological and biochemical characteristics of the variety, soil and climatic conditions of growth and technological methods of cultivation [1,2,3,4,5]. For high quality wine production, it is necessary to provide the processing of grapes with optimal conditions: balanced correlation between the content of acids and sugars (potential alcohol), as well as the components of the phenolic complex -extractable substances responsible for the formation of color, aromatic complex and structure of potential wine.…”

Assessment of the influence of foliar treatment on productivity and phenolic maturity of grapes

et al. 2021

An urgent task of today for grape growers is to find effective ways to achieve the compliance of conditional parameters to phenolic ripeness of grapes while maintaining high cropping capacity. In this study the influence of foliar treatment of grapes with nitrogen-containing preparations "Siamino Pro 500" on productivity and phenolic maturity of ‘Cabernet-Sauvignon’ grape variety was investigated. Studies were carried out during 2018-2019. Grape maturity degree was assessed by the Glories method, based on the determining of the total and extractable anthocyanin potential of grapes. It was shown that, as a result of the experimental scheme of processing, the cropping capacity increased by 10- 14%, as well as the bunch weight - by 13 - 16%. Use of the preparation contributed to the onset of technical maturity of grapes at the earlier period compared to the control. The content of anthocyanins extracted from the skins was 49- 56%. Experimental grape samples were characterized by a higher content of titratable acids (by 1.4 and 1.2 g/l) and a lower sugar accumulation (by 9 and 16 g/l). Positive influence of the experimental scheme of processing on organoleptic properties of wines was observed.
