Phaseolus vulgaris L. is a salt-sensitive species. For this reason, the purpose of the face work was to determine the effect of excess NaCl on the content of the chlorophyll pigments as an indicator of salt stress tolerance. Therefore, in the present study, of the influence of saline solutions of 100 mM and 200 mM NaCl was studied on the content of assimilatory pigments, to 7 local populations of common beans, collected from areas with saline soils, from Nord-East of Romania and grown under greenhouse conditions, at the pots. The experiment is part of a broader research, and the determination of pigment content is only one stage of this research, because and other physiological and biochemical parameters are analyzed. 15 days after treatment the content of chlorophyll a, chlorophyll b and carotenoids pigments showed higher values compared with analyzes performed after 30 days. The overall objective of the research is to contribute to a better understanding of the physiological mechanisms involved in the saline stress tolerance of Phaseolus vulgaris L., identification of local populations of salinity-tolerant beans and their use in breeding programs of this species. As novelty, in the current study, new genotypes were found of bean, from Nord-East of Romania, tolerant to this factor.

Geographical wine traceability is an important topic in the context of wine authentification. Therefore, many researchers have addressed this subject by developing different methodologies based on multivariate analysis of organic and inorganic parameters and also by isotopic signature. The goal of this research was to assess the potential of elemental composition and isotopic signature of lead (207Pb/206Pb, 208Pb/206Pb and 204Pb/206Pb) and strontium (87Sr/86Sr) of wines from three Romanian vineyards, in order to highlight reliable markers for wine geographical origin. The ICP-MS method was used for the concentration determination for 30 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, In, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Sr, Tl, V, U, Zn, Hg). In this study 10 wines (2 red and 8 white) obtained from ‘Merlot’, ‘Fetească neagră’, ‘Fetească albă’, ‘Fetească regală’, ‘Băbească gri’, ‘Șarba’, ‘Aligoté’, ‘Sauvignon blanc’, ‘Muscat Ottonel’, ‘Italian Riesling’ cultivars were investigated. The wine samples were obtained from micro-wine production under conditions of 2014, 2015, 2016 from Dealu Bujorului, Murfatlar and Ștefănești-Argeș vineyards. The high level of K (148.66±5.41-633.74±4.13 mg/L), Mg (88.23±0.84-131.66±3.42 mg/L), Ca (49.84±1.22-89.18±2.34) and Fe were observed in the wine samples analysed. Heavy metals like Hg, Pb, As and Cd (10.2-315 µg/L) were found below acceptable limits. Concentration of Na (1 mg/L), Cu (1 mg/L), As (0.2 mg/L), Cd (0.01 mg/L), Zn (5 mg/L) and Pb (0.15 mg/L) metals in analysed wine samples were under Maximum Permissible Limits (MPL), respectively as published by the Organization of Vine and Wine. The variation of the 207Pb/206Pb, 208Pb/206Pb, 204Pb/206Pb and 87Sr/86Sr ratio and K/Rb, Ca/Sr of the investigated wine clearly demonstrated that these variables are suitable traces for wine geographical origin determination. The proposed methodology allowed a 100% successful classification of wines according to the region of provenance.

Florin Dumitru Bora Anamaria Călugăr Claudiu Ioan Bunea V. R. Filimon

The present study is focused on the determination of mineral composition of international red wines (Merlot, Cabernet Sauvignon), white wines (Sauvignon blanc, Aligoté, Muscat Ottonel, Italian Riesling) and native red wines (Feteasca neagră, Burgund mare, Băbeasca neagră), white wines (Feteasca regală, Fetească albă, Băbeasca gri, Șarba) produced in the Dealu Bujorului vineyard between 2014-2018, using Inductively Coupled Plasma Mass-Spectrometry (ICP-MS), and comparison of mineral composition of the soil. The high level of Ca, K, Na, Mg, P and Fe was observed in analyzed wine samples, the concentration of Na, Cu, As, Cd, Zn and Pb metals in analyzed wine samples were under Maximal Permissible Limit. The average concentrations of elements in the soil decrease in the following order: K, Na, Ca, Cu, Fe, P, Mg, Li, Co, Mn, Zn, Pb, Cr, As, U, Cd and Hg. Cu concentration in the topsoil of the Dealu Bujorului vineyard exceeds the maximum allowed limit (20 mg/kg Cu).

A. Albu Florin Dumitru Bora Simona-Maria Cucu-Man Vasile Stoleru C. E. Nistor

The study of honey in Iași County reveals its ecological, economic and health importance, emphasizing its unique properties, role in biodiversity and value in promoting sustainable beekeeping and regional identity. This study aimed to investigate the characteristics of honey from Iasi County, Romania, analyzing 27 samples collected in 2020 and 2021. The samples include: tilia (8 raw, 7 commercial), acacia (2 raw, 2 commercial), rapeseed (3 raw), sunflower (3 raw) and lavender (2 raw) honey. Analyses were carried out under Romanian/EU standards, assessing parameters such as: color, electrical con-ductivity, moisture, total soluble solids (TSS), acidity (free, lactone, total), pH, hydroxymethyl-furfural (HMF), ash and mineral composition (Na, K, Ca, Mg, Cu, Zn, Mn, Fe). The results revealed significant differences between raw and commercial honeys. Notably, in commercial tilia honey, higher values were found for color (38.58 mm Pfund vs. 24.14 mm Pfund), total acidity (25.93 meq·kg⁻¹ vs. 17.36 meq·kg⁻¹), and HMF levels (8.84 mg·kg⁻¹ vs. 3.68 mg·kg⁻¹). Conversely, water insoluble solids (0.08 % vs. 0.15 %) and ash content (0.21 % vs. 0.30 %) were lower in commercial samples. Potassium was the most abundant mineral detected, while copper and zinc levels were the lowest. Significant correlations were observed between several parameters, including ash with electrical conductivity and HMF with acidity. This study underscores the impact of processing on honey quality and highlights the importance of understanding honey composition for consumers and producers alike.

Investigation of the Copper Content in Vineyard Soil, Grape, Must and Wine in the Main Vineyards of Romania: a Preliminary Study

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca Horticulture (2019)

Alina Donici Claudiu Ioan Bunea Anamaria Călugăr Eugenia Hărşan Florin Dumitru Bora

The long-term use of copper in viticulture has caused great copper accumulation in vineyard soils, resulting in negative effects on the environment through toxicity to aquatic and soil organisms. The aim of this study was to investigate the copper content in vineyard soils, grapes and wines from Dealu Bujorului, Murfatlar, Tarnave, Iasi and Ştefăneşti vineyards. The ICP-MS method was used for copper determination in vineyard soil, grape must and wine. Copper concentration in red wine samples was significantly higher than in the white wine samples. Values for Transfer Factor and Mobility Ratio indicates that Vitis vinifera L. does not allow the accumulation of copper from vineyard soil in must grape and wine. The copper concentration in grapes, must and wine has been influenced by the copper concentration in soils, by copper fungicide used to protect the vine and by other factors such as the biological specificity of cultivars during growth.

THE PRODUCTION OF LOW-ALCOHOL WINES BY SEQUENTIAL SEMI-ANAEROBIC MUST FERMENTATION

Journal of Applied Life Sciences and Environment (2023)

V. R. Filimon Roxana Mihaela Filimon Ancuța Nechita Florin Dumitru Bora Liliana Rotaru

Nowadays, consumers go towards products that provide food security and nutritional richness, consumption of highly alcoholic beverages not complying with these health-related requirements. This study aimed to obtain low-alcohol wines by performing sequential alcoholic fermentation of grape must (Muscat Ottonel). Thus, 11 commercial yeast strains (10 Saccharomyces cerevisiae and 1 Torulaspora delbrueckii) were preliminarily tested in anaerobic and semi-anaerobic conditions. Based on laboratory tests, grape must fermentation was sequentially initiated in semi-anaerobic conditions (loose cotton plugs; intermittent homogenization), with the T. delbrueckii strain (106 CFU/mL) and the addition of preliminarily selected S. cerevisiae strains (104 CFU/mL), to the consumption of 50% of the sugars in the must, to complete the fermentation. By applying this technology, dry wines were obtained with an alcohol content lower by up to 1.10% vol., but with a lower concentration of volatile terpenes, due to additional must oxidation. Also, semi-anaerobiosis enhanced glycerol synthesis by yeasts (< 35%), with a positive impact on the sensory characteristics of the wine.
