For several thousand years, vine has been grown in the Carpathian basin, where the climatic and soil conditions are favourable for viticulture. During this long period, vine growing has been developing until it reached its current niveau. We grow propagation material, table grape and wine grape. The produced wine grape varieties are grown on the largest area, of which 72% is white wine and 25% is red wine. Only 3% remains for table grapes. The surface of vineyards is about 63 000 ha, which can be found in 22 wine regions. The biodiversity of vine is very rich in our country. There are a lot of native and valuable bred varieties and clones in cultivation. The resistant and winter frost resistant vine varieties have an important role in our continental climate. The in 75% of the vineyards is on hills and mountains, 25% of them is on the Great Hungarian Plain. High cordon with cane pruning dominates the training and pruning system. Unfortunately, vine stocks suffer from a lot of diseases and by using pesticides we pollute the nature. Viticulturists in Hungary produce excellent raw material and provide oenologists with them who make wine of excellent quality.

Inflammation, thrombosis and oxidative stress are rarely studied together when wine’s biological activity is concerned; hence the existing literature lacks a holistic point of view in the biological outcome. The scope of the present study is to parallel evaluate the effect of wine extracts on those mechanisms. Ten wine varieties and two different extraction methods were used leading to five extracts for each wine: total lipids (TL) and fractions with different phenolic compound classes (FI, FII, FIII and FIV). Their effect on oxidative stress, platelet aggregation and the secretion of cytokines from mononuclear cells was measured and a biological score was calculated. FII of white wines is the most potent extract and the extracts FIII and TL are following. Specifically, FII had higher anti-oxidant and anti-inflammatory score while all three fractions had a similar anti-platelet score. Furthermore, FII and FIII extracts were the most potent red wine extracts and revealed the highest anti-oxidant and anti-inflammatory scores. White wine FII extracts were more potent than the red wine ones while FI and FIV extracts of red wine were more potent than the white wine ones. In conclusion, the protective effect of a wine is independent of its color but is strongly associated with its microconstituents profile. FII extract revealed the highest biological score and further examination is needed in order to identify the compounds that are responsible for the aforementioned actions.

Term Storage

Grapes are rich in easily digestible carbohydrates, mineral compounds, vitamins, phenolic compounds. and other vital components. It is known that fresh grapes can be used from September to December. To prolong the terms of consumption of this valuable raw material, the most appropriate varieties and conditions for storing grapes have been determined. White, pink, and red grape varieties were taken as the object of research. The changes in the activity of the pectinesterase enzyme were determined depending on the degree of ripening of table grape varieties, the change in the pectinesterase enzyme during storage of table grape varieties in various variants was investigated. Statistical processing and calculation of variations in the indicators of changes in the activity of the enzyme pectinesterase were performed, depending on the degree of ripening of grapes of the Shamakhi Marandi variety. During the study, the pectinesterase enzyme remained more stable in mature varieties. This means that in ripe table grape varieties, the absorption of nutrients in the respiratory process is significantly slowed down. However, as they mature, the activity of the pectinesterase enzyme gradually increases. Therefore, for long-term storage in refrigerated chambers, fully ripe varieties of table grapes were used; to this end, grapes of the white Ganja table variety, the pink Shamakhi Marandi variety, and the red Black Asma variety are more suitable. The comparison of the investigated variants showed that table grape varieties, when stored in a refrigerated chamber in a controlled atmosphere, at 3–4 % CO2 and 2–3 % O2, retain better quality than other variants. When storing table grape varieties of various variants in the refrigerator, the enzyme activity decreases but is not completely suppressed.

The paper presents the results of a study on the content of free amino acids, including essential ones, vitamins C and P, biologically important macro- and microelements in table grapes of the middle ripening varieties Ag raisins, Vezne, Galan, Hamburg Muscat and Samur, cultivated on the plain in Southern Dagestan Region. The qualitative composition and quantitative content of free amino acids were determined by HPLC on an AAA-881 analyzer. Amino acids tryptophan, cystine and methionine were identified by paper chromatography due to the fact that they decompose when exposed to a temperature of 102 ° C in the amino analyzer reactor. The mass concentration of vitamin C was identified titrimetrically, vitamin P was identified colorimetrically (FEK-56M, Russia), the mineral composition of grapes was identified by flame and atomic absorption photometry using Flapho-4 (Germany) and Hitachi-208 (Japan) devices. Each of the varieties had 18 amino acids, including a full set of essential ones. The total number of detected amino acids was 368.5 (Ag raisins) - 279.9 mg / dm3 (Vezne), and irreplaceable ones - from 103.8 (Hamburg muscat) to 132.4 mg / dm3 (Ag raisins). All experimental grape samples contained vitamins C, from 2.6 (Galan) to 3.7 mg / dm3 (Ag raisins) and P - from 78.0 (Samur) to 131.3 mg / dm3 (Galan), as well as physiologically important minerals. Studies have shown that in terms of the amount of free amino acids, including essential vitamins C and P, healthy minerals, such grapes as Ag raisins, Vezne, Galan, Hamburg and Samur Muscat, grown in the south of Dagestan are natural products with functional properties. Eating it fresh contributes to the normalization of metabolic processes in the human body. Additionally, these grapes can be successfully used as a raw material for the production of multicomponent functional food.

Mineral composition of wines is affected by many ecological and technological factors. These variables are mostly discussed focusing on certification of origin and human health. This paper gives data on possible changes in mineral composition and pH of wines due to 4 hours skin maceration (1st trial) and fermentation sur marc (2nd trial). Experimental site is situated on acidic sandy soil in middle east Hungary. The variety collection was established in 2003 with own rooted planting material in 3x1 m spacing, trained for single curtain trainingsystem. Mineral composition of wines was determined with ThermoFischer Scientific iCAP 6300 ICP-OES, pH was measured with pH10pen (VWR International) in field, and with SevenEasyTM pH meter (Mettler Toledo) in laboratory. 1st trial with 9 PIWI white wine grape varieties pointed to demonstrate effects of skin maceration, which is abundantly used to elevate aroma content. 2nd trial with the use of ‘Medina’ red PIWI grape variety aimed to demonstrate effects of double pasta skin maceration in rose and red wine technology. Data of 1st trial show, that K, Cu, Mn and P respective increase with skin maceration, despite Fe show considerable decrease. Data of 2nd trial show, that K, Mg, Mn, P, Sr and B increase with longer skin contact and higher fermentation temperature, despite Fe and Ba decrease with this technology. In regard to pH, data show, that skin maceration and fermentation sur marc increase K content with about 30-70% respectively, withstanding that pH also increase with a considerable 0,4-0,5 value. K content can be higher in the end product, despite to earlier higher level of tartrate formation. An attention should be driven to lower level of tartaric acid and consequently higher pH characteristic for wines produced with the application of skin maceration or fermentation sur marc.

The results of the technological assessment of white technical grape varieties growing on the ampelographic collection of the institute are shown: Riesling, Grubella, Goruli mtsvane, No-rock, Khotsa tsibil. Samples of dry white wines were prepared using classical technology. The research was carried out in the laboratory of winemaking technology in micro-winemaking conditions. The weight of one batch of grapes was 7–15 kg. The main physical and chemical parameters of wort and wine were determined. As a result of the organoleptic assessment, con-clusions were drawn about the advisability of using these varieties for the production of natu-ral white table wines. Riesling was chosen as a control variety. Wine materials from the re-searched varieties were distinguished by their typical, pale straw color, with a greenish tint, delicate varietal aroma, full, harmonious taste. This indicates a high potential of the studied varieties for the preparation of high-quality wines.
