Summary: Grape pomace and seeds are valuable winemaking by-products with oils containing beneficial bioactive compounds. The oils from pomace and seeds differ in fatty acid composition and tocopherol content, but all oils exhibit good indicators of nutritional quality.

Summary: This study characterized grape stem extracts from different grape varieties from two vintages (2016 and 2018), revealing significant differences in antioxidant activity, total phenolic content (TPC) and total flavonoid content (TF) among different varieties and vintages. It was observed that extreme temperatures and accumulated precipitations in 2016 had an impact on polyphenol synthesis, resulting in higher TPC and TF values in grape stems from the 2018 vintage. Statistical analysis showed that environmental factors such as light, temperature, and precipitations have different impacts on polyphenol synthesis depending on the specific compound family.

Summary: The phenolic and elemental profiles of Serbian autochthonous grape varieties `Smederevka' and `Plovdina' were compared with international varieties, showing rich phenolic content and potential positive interactions among abundant elements. Health risk assessment suggested all samples were safe for human consumption, indicating the potential benefits of these grape varieties.

Summary: This study evaluated the variation in traits within five common wine grape varieties and found that these varieties exhibit intraspecific variation along a leaf economics spectrum (LES). Variety identity was the main factor influencing physiological and morphological traits, while growth stage influenced chemical traits and leaf mass. All varieties exhibited greater resource-conserving traits later in the growing season. Leaf hydraulic traits, including water-use efficiency, were unrelated to other resource capture traits and were better explained by spatial location.

Summary: The impact of seeds on anthocyanin extraction from skins was studied in four Italian red winegrape varieties. The presence of seeds did not significantly affect the extracted anthocyanin content and forms, but led to an increase in the polymerization rate. Anthocyanins adsorbed on seed surface were quantified for the first time, with a variety-dependent amount of less than 4 mg/kg berries. Individual anthocyanin forms were adsorbed mainly based on their abundance in solution, with cinnamoyl-glucoside forms showing a higher affinity with seed surface.

Summary: This research investigated the evolution of monoterpenoids and the expression profiles of biosynthesis genes in the MEP pathway in different table grape varieties. The results showed that there were three evolutionary patterns for monoterpenoid volatiles during berry development, and the first biosynthesis gene VvDXS3 was significantly correlated to the accumulation of monoterpenoids.

Summary: This study aimed to determine the phenolic, vitamin, and fatty acid contents of the Okuzgozu and Bogazkere varieties of Vitis vinifera L. and their effects on antioxidant activity. Results showed that the Okuzgozu variety had significantly higher levels of unsaturated fatty acids, phenolic compounds, and vitamins, leading to a stronger antioxidant effect compared to the Bogazkere variety.

Summary: The study aimed to track the ripening season of table grapes using non-destructive tools and estimate the anthocyanin content. Results showed strong correlations between the Multiplex(R) indices and anthocyanin content, indicating that Multiplex(R) 3 can be an effective non-destructive tool for rapid estimation of table grapes' anthocyanin content.

Summary: This study investigated the impact of factors such as elaboration processes, irrigation conditions, and crop year on acrylamide content and antioxidant compounds in table olives. It was found that regulated deficit irrigation resulted in lower acrylamide levels in certain olive varieties. Additionally, the antioxidant activity was highest in olives harvested in the 2019 crop year. The selection of irrigation and elaboration methods is crucial for ensuring desirable acrylamide levels.

Summary: This study aimed to characterize the phenolic composition, antioxidant, and anticancer activity of grape skin extracts (GSEs) from nine new table grape genotypes. Results showed that GSEs had different flavonoid and non-flavonoid profiles, and all possessed antioxidant activity, with 'Aika N.', 'Turese N.', and 'Egnatia N.' being the most active. 'Daunia N.' and 'Apenestae N.' exhibited promising anticancer activity against the tested cancer cell line.

Summary: This work evaluated the phenolic content, anthocyanin content, antioxidant activity, and volatile composition of unstudied seedless table grape varieties. The results showed that Adora and Melody exhibited higher phenolic content, anthocyanin content, and antioxidant activity compared to other varieties. Adora was selected for its antioxidant properties and flavor characteristics based on the results.

Summary: Microscopic bud dissection can be used to assess grapevine bud fruitfulness prior to winter pruning, providing useful insights for viticulturists to guide their pruning practices and predict potential yield. The findings suggest that bud dissection can offer valuable data for vineyard management decisions.
