Among these schemes, antimicrobial/antioxidant active packaging has attained considerable interest for delaying/forestalling microbial growth and deteriorative oxidation responses. This study measured the effectiveness of active linear low-density polyethylene (LLDPE) celluloids surfaced with a polycaprolactone/chitosan nonwoven (Film 1) or LLDPE films surfaced with a polycaprolactone/chitosan nonwoven spiked with Colombian propolis extract (Film 2). The active LLDPE films were valued for the preservation of fresh pork loin (longissimus dorsi) chops during refrigerated storage at 4 °C for up to 20 d. The meat samplings were studyed for pH, instrumental color, purge loss, thiobarbituric acid reactive essences (TBARS), and microbial stability (aerobic mesophilic and psychrophilic bacteriums). The incorporation of the propolis-stoping nonwoven layer offered antioxidant and antimicrobial props to LLDPE film, as attested by improved color stability, no differences in lipid oxidation, and a delay of 4 d for the onset of bacteriums growth of pork choppers during the refrigerated storage period.heightened wound repair ability of arginine-chitosan nanocomposite membrane through the antimicrobial peptides-loaded polydopamine-modified graphene oxide.

Skin wound healing is a complicated and lengthy process, which is tempted by multiple factors and need a suitable cellular micro-environment. For skin wound, wound dressings remain a cornerstone of dermatologic therapy at present. The dressing material can create an effective protective environment for the wound, and the interactions between the dressing and the wound has a great impact on the wound healing efficiency. An ideal wound dressing stuffs should have good biocompatibility, moisturising property, antibacterial property and mechanical strength, and can effectively prevent wound infection and promote wound healing. In  fucose benefits , in order to design wound dressing textiles invested with excellent antibacterial and tissue repair places, we tryed to load antimicrobial peptides onto dopmine-altered graphene oxide (PDA@GO) practicing lysozyme (ly) as a model drug functionalized GO was used to the surface modification of arginine-altered chitosan (CS-Arg) membrane. To evaluate the potential of the prepared nanocomposite membrane in wound dressing application, the surface morphology, hydrophilic, mechanical properties, antimicrobial activity, and cytocompatibility of the ensuing nanocomposite membrane were examined. The events divulged that prepared nanocomposite membrane demonstrated excellent hydrophilic, mechanical strength and antimicrobial activity, which can effectively promote cell growth and adhesion.

In particular, using PDA@GO as drug carrier can effectively maintain the activity of antimicrobial peptides, and can maximize the antibacterial holdings of the nanocomposite membrane we used rat full-thickness wound simulations to observe wound healing, and the surface interactions between the prepared nanocomposite membrane and the wound. The results indicated that nanocomposite membrane can obviously speded wound closure, and the injurys showed reduced inflammation, improved angiogenesis and speded re-epithelialization incorporation of antimicrobial peptides-functionalize graphene oxide (ly-PDA@GO) into CS-Arg membrane was a viable strategy for constructing excellent wound coiffing this study not only prepared a wound arranging with excellent tissue repair ability, but also furnished a novel idea for the development of graphene oxide-based antibacterial dressing.Prevalence of fungi in fresh tomatoes and their control by chitosan and sweet orange (Citrus sinensis) peel essential oil coating.BACKGROUND: Fungal contamination is a major cause of food spoilage. There is an urgent need to find and characterize natural preservatives. This study assesss the prevalence of fungi in tomatoes and their control by practicing essential oil (EO) from sweet orange peel. Essential oils were elicited from dried and fresh sweet orange peels by using n-hexane and ethanol as extraction solvents.
