In this study, the potential value of dried grape pomace (whole, seed, and skin) obtained from Fetească Neagră (FN) Tămâioasă Românească (TR) as a source secondary metabolites was evaluated following hydroethanolic extraction. The total polyphenol, flavonoid, anthocyanin contents FN TR extracts have been determined, along with their antioxidant antimicrobial activities. investigation seeds whole revealed higher levels content in comparison to those extracted TR. Fifteen polyphenolic compounds were identified through ultra-high-performance liquid chromatography (UHPLC) analysis. most abundant concentrations catechin epicatechin detected seed derived both Romanian varieties. activity skin than evaluation demonstrated that 15 out 18 reference pathogenic bacteria exhibited low MIC MBC values, indicating strong antibacterial extracts. No anti-Candida observed.

This study aimed to investigate the chemical composition, fatty acid profile and polyphenol content of Provola cheese made with cow’s milk from cows fed a diet incorporating olive cake. Cheese samples were analysed in different months order test diet×season effects. The results show that composition was influenced by both factors. most beneficial human health point view produced treatment spring. Supplementing dairy cake reduced atherogenic thrombogenic indices while increasing total polyphenols product. With 32.9% increase polyphenols, TEST group has greater functional nutrients properties than CTR group. data that, combining benefits more sustainable production process better final product, supplementation dried stoned cow improves nutritional cheese.

The main objective of this research is to assess the antifungal activity grape pomace extracts four local varieties (i.e., two white, Fetească Albă and Tămâioasă Românească, red, Neagră Negru de Drăgășani), knowing their valuable chemical profile. was evaluated using fungi strains (Aspergillus niger Alternaria alternata). Despite classical extraction method, absolute ethyl alcohol (99–100%): water=1:1 as a solvent, obtained presented high effectiveness. Thus, Românească (TR), (FN), (FA), Drăgășani (ND) were shown have superior antimicrobial against Aspergillus due higher concentration polyphenols. On other hand, FN ND did not exhibit sp., although growth inhibition efficiency lower compared sp. In conclusion, study emphasized strong correlation between analyzed excellent antioxidant potential.
