“…To the best of our knowledge, these TPC and TFC values for the extracts obtained from the fresh GF peels cultivated in Egypt have not been reported in the literature to date. However, for other geographical locations, the value of the TPC of the grapefruit peel extracts can range from approximately 50 to 200 mg GAE/extract [60][61][62][63]. For instance, with 80% ethanolic extraction, the TPC was about of 20 mg GAE/g DE using GF peels cultivated in Pakistan [10].…”

Grapefruit (GF) processing generates significant nutrient and economic losses due to the production of 50% by-products, primarily peels. GF peels are a rich and sustainable source of bioactive compounds (BCs), such as essential oils (EOs) and phenolic compounds. Thus, finding value-added solutions based on a circular economy is paramount. This research aims to assess the antioxidant, anti-inflammatory, and antimicrobial properties of a hydroethanolic polyphenol-rich extract from crude GF peels (GF-CE), essential oil (GF-EO), and polyphenol-rich extract from GF peels after essential oil extraction (GF-PE). The GF-CE and GF-PE showed high concentrations of naringenin (7.71 and 48.60 mg/g dry extract (DE)), narirutin (15.03 and 28.73 mg/g DE), and hesperidin (0.67 and 0.29 mg/mL), respectively. Extracting firstly EOs from GF improved the release of phenolic acids (p-coumaric, ferulic, and chlorogenic acid). The GF-CE exhibited stronger free radical scavenging activity mainly in DPPH (IC50 = 75.69 ± 0.81 µg/mL) than GF-EO (1271 ± 0.85 µg/mL) and GF-PE (113.45 ± 0.85 µg/mL). The GF-EO demonstrated moderate antimicrobial activity against Gram-positive bacteria compared to the reference standard (amoxicillin) and strong activity against the yeast Candida albicans (inhibition zone of 16 mm). The major compounds in the GF-EO included D-limonene (25%), nootkatone (24%), and β-pinene (8%). Both polyphenol-rich extracts showed promising activities as COX1 and COX2 inhibitors with IC50 values of 25 ± 0.1 and 0.28 ± 0.00 µg/mL (compared to celecoxib (97.5 ± 0.1 and 0.31 ± 0.01 µg/mL) and indomethacin (6.25 ± 0.00 and 0.52 ± 0.01 µg/mL) as the standards), respectively. The study concludes that GF peels are a valuable source of BCs with significant bioactivities, offering a sustainable multi-cascade approach to recovering value-added compounds from GF peels in alignment with circular economy principles and open opportunities as functional ingredients for food applications.

“…Under these conditions, the foodborne disease hazard of raw meat products should be considered. These foods are generally not subjected to post-treatment processes that eliminate or reduce dangerous pathogens before consumption [5,6]. In various ways, foodborne pathogenic microorganisms can adhere to surfaces, form colonies on meat, and endanger human health [6].…”

The aim of this study was to determine the microbial stability, challenge to L. monocytogenes, and some physicochemical properties of turkey breast meat by alginate-based coating enriched with postbiotics (8% concentration, CFS) of Bifidobacterium bifidum DSM 20456 and Bifidobacterium bifidum BB12 strains. For this purpose, firstly, some antimicrobial and total phenolic matter, flavonoid, and DPPH activity values of postbiotics were determined. In addition, FTIR analysis was performed to see the intermolecular interactions of the biological coating agent. As a result of the study, alginate solution with postbiotic showed significant differences in pH, a*, b*, yeast-mold values of turkey meat during storage (7 days), while L* value, total aerobic mesophilic bacteria count (TMAP), psychrotrophic bacteria (PAB), lactic acid bacteria (LAB) and Listeria monocytogenes count were not effective (p&gt;0.05).
