The multifunctional packaging used for fresh food, such as antioxidant and antimicrobial packaging, can reduce food waste. In this work, a polylactic acid (PLA)-based composite film with antibacterial properties was prepared by using nano-zinc oxide (ZnONPs) pomegranate peel extract (PEE) via the solvent-casting method. Different amounts of PEE (0.5, 1, 1.5 2 wt%) 3 wt% ZnONPs were added to PLA produce active films. results various characterizations (SEM, XRD, etc.) showed that uniformly dispersed in film. Compared films, PLA/ZnONPs/PEE films an increased UV barrier, water vapor permeability elongation at break, decreased transparency tensile strength. addition, activity evaluated based on DPPH ABTS. maximum ABTS scavenging activities 96.2 ± 0.8% 93.1 0.5%. After 24 h, inhibited 1.4 0.05 Log CFU/mL S. aureus 8.2 0.35 E. coli, compared blank group. had good activities. Therefore, great potential packaging.

Chinese herbs have been used as feed additives in animal production. This study investigated the effects of a herbal feed-additive (TCM, which contained Elsholtzia ciliate, Atractylodes macrocephala, Punica granatum pericarpium, and Cyperus rotundus) on production performance, egg quality, antioxidant capacity, immunity, intestinal health Roman laying hens. A total 720 28-week-old hens were randomly allotted to three groups with six replicates forty each. The fed basal diet (CON group), 50 mg/kg zinc bacitracin (ABX or 400 TCM (TCM group) for 56 days. results showed that group increased production, mass, albumen height, Haugh unit compared CON (p < 0.05). There no significant differences weight, intake, conversion rate, eggshell strength among all > Compared group, enhanced activities glutathione peroxidase, superoxide dismutase serum liver, reduced malondialdehyde content also levels interleukin-2, interferon-γ, immunoglobulin A, M, G, decreased interleukin-6 interleukin-8 Furthermore, jejunal goblet cell density ileal crypt depth lymphocyte 16S rRNA demonstrated can change diversity composition microbiota.

A commonly wasted agricultural waste, pomegranate peel has attracted attention as a useful biomaterial with wide range of potential uses. Fruit and vegetable wastes create environmental difficulties, well loss valuable biomass financial cost to enterprises, due its high biodegradability. This study focuses on the extraction characterization cellulose from both outer inner layers peel. The process involves multi-step approach, encompassing delignification mercerization. Fourier transform infrared spectroscopy (FTIR) revealed characteristic peaks associated cellulose, confirming presence in extracted material. Field emission scanning electron microscopy (FESEM) depicted morphological transformation non-cellulosic components were removed during process. Particle size analysis demonstrated that alkaline treatment reduced particle size. X-ray diffraction (XRD) indicated significant increase crystallinity elimination hemicellulose lignin following chemical composition treated peels contained higher content compared their untreated counterparts. offers insightful information about possible uses adaptability different application.

The improper use and abuse of antibiotics have led to an increase in multidrug-resistant (MDR) bacteria resulting a failure standard antibiotic therapies. To date, this phenomenon represents leading public health threat the 21st century which requires alternative strategies fight infections such as identification new molecules active against MDR strains. In last 20 years, natural extracts with biological activities attracted scientific interest. Following One Health Approach, by-products represent sustainable promising solution. Consistently, aim present study was evaluate antimicrobial activity hydro-alcoholic pomegranate peel extract (PPE) microorganisms belonging Enterococcus faecium , Staphylococcus aureus Klebsiella pneumoniae Acinetobacter baumannii Pseudomonas aeruginosa, Enterobacter spp. “ESKAPE” group pathogens. Through semiquantitative quantitative methods, PPE showed effective Gram-positive Gram-negative bacteria. kinetics bactericidal action highlighted that microbial death achieved time- dose-dependent manner. High concentrations exhibited antioxidant activity, providing protective effect on cellular systems red blood cell membranes. Finally, we report, for first time, significant intracellular antibacterial property by its staphylococcal reference strain bacteriostatic clinical resistant HeLa line. conclusion, due characterized content polyphenolic compounds strength, could be considered therapeutic agent alone or conjunction challenging caused ESKAPE

Hot water blanching at 80 °C for 3 min can be used as a novel pre-treatment step in pomegranate peel to preserve the integrity of phytochemical content within extracts by lowering or inactivating enzymes such polyphenol (PPO) oxidase and peroxidase (POD) that are responsible break-down phytochemicals peel. The aim this study was investigate effect hot on yield, bioactive compounds, antioxidants, enzyme inactivation, antibacterial activity ‘Wonderful’, ‘Acco’, ‘Herskawitz’ extracts. We variety spectrophotometric-based assays liquid chromatography mass spectrometry (LC-MS)-based approach characterize quantify metabolites Blanching significantly (p < 0.05) reduced PPO all extracts, with highest reduction 0.25 U/mL. Furthermore, higher antioxidant blanched using 2,2-diphenyl-1-picryl hydrazyl (DPPH) activity, ferric ion reducing power (FRAP), 2,2-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging 567.78 ± 9.47 µmol Trolox/g DM, 800.05 1.60 915.27 0.61 respectively, noted. were recorded lowest minimum inhibitory concentration (MIC) value µg/mL Gram-positive Bacillus subtilis Gram-negative Klebsiella pneumoniae bacteria strains. A total 30 present ‘Acco’ tentatively identified after LC-MS profiling. This demonstrates from cultivar have great potential commercial use value-added products nutraceutical, cosmeceutical, pharmacological industries.
