Grape pomace (GP), a byproduct of winemaking, has gained significant attention as a sustainable and functional ingredient with applications in the food and nutraceutical industries. This review examines the potential of GP in meat products and analogs, functional foods, and nutraceuticals, highlighting its composition, health benefits, and role in enhancing nutritional and functional properties. Rich in dietary fiber, polyphenols, essential fatty acids, and bioactive compounds, GP exhibits antioxidant, anti-inflammatory, and gut health-promoting effects, making it suitable for various food applications. Its incorporation into meat products, such as sausages and patties, improves texture, enhances shelf life, and increases nutritional value while reducing the environmental footprint. GP is also effective in functional foods such as baked goods, dairy and plant-based yoghurts, smoothies, and snack bars, where it can enrich fiber and polyphenol content, aid in satiety, and provide health benefits beyond basic nutrition. The challenge is how to maintain the sensory properties characteristic of conventional, unmodified products. In nutraceuticals, GP’s polyphenolic compounds and dietary fiber support antioxidant, anti-inflammatory, and metabolic health functions, with applications as antioxidant supplements, gut health boosters, weight management aids, and cardiovascular health supplements. Despite challenges such as taste modification and optimizing bioavailability, GP’s versatility and sustainability highlight its value in developing innovative, health-oriented products. This review emphasizes the promise of GP as a valuable ingredient in functional foods and nutraceutical formulations, contributing to health, sustainability, and resource efficiency.

This paper presents the main trends in antimicrobial resistance (AMR), as well as their health and other consequences; current knowledge about the emergence, spread, and mechanisms of AMR; and the progress to date in understanding possible pathways of resistance through the food chain and the role of food as a vector of antibiotic-resistant bacteria. We have reviewed the main approaches to the prevention and control of the development, selection, and spread of AMR in food-producing animals (FPAs) and the meat industry; bacterial AMR in FPA; the most significant and dangerous pathogens that show AMR; transmitted by meat and meat products; strategies to prevent the occurrence of AMR microorganism infections; and, recently, AMR monitoring and surveillance programs in meat production and processing. This study reviews the results of various studies, as well as inspiring and motivating reviews, that address the state of the art of AMR in targeted diverse niches that are integrated by the multidisciplinary “One Health” approach, as well as future strategies for reducing AMR. To successfully address the challenges associated with AMR, it is necessary to integrate monitoring and surveillance across the environment–raw materials–food (meat)–people continuum. It is necessary to permanently improve and expand the NCBI Pathogen Detection Isolate Browser (NPDIB) database and supplement it with the results of future research to identify and investigate genes that coordinate stress response and AMR.

Objectives: This study was conceived with the aim of translating the experience and knowledge of the research group into the design and creation of multi-active phytocomplex cocktails from lyophilised winery by-products (Grape Pomace—GP) and weeds (Sambucus ebulus L., Dwarf Elder—DE). Methods: Quantification of bioactive molecules was performed by high-performance liquid chromatography (HPLC) method. Results: In the extract obtained from lyophilised GP, the most dominant component that was quantified was petunidin-3-glucoside. Prominent compounds that were quantified in DE extract were cyanidin derivatives. The total number of microorganisms in lyophilisates is low, but some of them still survive lyophilisation. Antibacterial activity was determined by microdilution, the minimum inhibitory concentration (MIC) of the tested bacteria ranged from 0.78 mg/mL to 25.00 mg/mL. Antibacterial susceptibility testing (AST) revealed that Klebsiella spp. and Acinetobacter baumannii complex are extensively drug-resistant (XDR). Conclusions: The GP + DE cocktail showed very strong AB power against both tested XDR bacteria. The total phenolic content and antioxidative effect (determined spectrophotometrically) indicate their linear correlation.

This study evaluated the quality dynamics of artisanal (A) and semi-industrial (S-I) Sjenica white-brined cheese during 60-day ripening and assessed the agreement between a commercial near-infrared (NIR IR) spectroscopy calibration and reference methods for process monitoring. The reference methods showed that cheese type significantly affected proteins (p = 0.002), pH (p = 0.001), titratable acidity (p = 0.001), and fat-in-dry-matter (FDM; p = 0.038). The S-I cheese demonstrated superior hygiene under mandatory HACCP principles (E. coli max 1.73 log CFU/g vs. 3.72 log CFU/g in A). Ripening time significantly altered the color and texture profile analysis (TPA) parameters (p < 0.05). Principal component analysis (PCA) completely discriminated both cheese types at day 60, based on CVS color (86.27% variance) and textural attributes (87.08% variance). Sensory evaluation showed that assessors could discriminate between the two cheese types, while both maintained high overall acceptance. Deming regression and Bland–Altman analysis revealed poor quantitative agreement, with NIR systematically underestimating dry matter (−2.49 g/100 g), fat (−1.88 g/100 g), FDM (−1.80 g/100 g), protein (−1.04 g/100 g), and NaCl (−0.40 g/100 g). Overall, the results demonstrate that the production system significantly affects the physicochemical, microbiological, textural, and color characteristics of Sjenica white-brined cheese during ripening, while both the S-I and A cheeses retain high sensory acceptance.
