Due to short shelf-life of ber fruits, developing postharvest protocols incorporating nonchemical compounds with the aim extending its shelf life and maintaining quality is one major issues regarding fruit industry. The fruits greatly affected by factors especially temperature treatment. In present study, effect chitosan coating storage on physicochemical characteristics was investigated as a f...

Biofouling is a problem common in all systems where microorganisms and aqueous environment meet. Prevention of biofouling is therefore important in many industrial processes. The aim of this study was to develop a method to evaluate the ability of material coating to inhibit biofilm formation. Chitosan-coated polypropylene nonwoven textile was prepared using dielectric barrier discharge plasma ...

Meat is one of the most challenging food products in the context of maintaining quality and safety. The aim of this work was to improve the quality of raw/cooked meat by coating it with sodium alginate (A), chitosan (C), and sodium alginate-chitosan polyelectrolyte complex (PEC) hydrosols. Antioxidant properties of A, C, and PEC hydrosols were determined. Subsequently, total antioxidant capacit...

Campylobacter species are common bacterial pathogens associated with human gastroenteritis worldwide. The objectives of this study were to determine the minimum inhibitory (MIC) and minimum bactericidal (MBC) concentrations of allyl isothiocyanate (AITC) against 4 Campylobacter jejuni strains in Mueller-Hinton (MH) broth at 4, 21, 37 and 42°C and to screen the C. jejuni strains for their abilit...

The aim of the present study was to develop a ghrelin-containing formulation based on liposomes coated with chitosan intended for nose-brain delivery for the treatment of cachexia. Among the three types of liposomes developed, anionic liposomes provided the best results in terms of encapsulation efficiency (56%) and enzymatic protection against trypsin (20.6% vs 0% for ghrelin alone) and carbox...

BACKGROUND The purpose of this study was to formulate and evaluate nano lipid vesicles of methotrexate (MTX) for its anti-rheumatoid activity. METHODS In this study the principle of both active as well as passive targeting using MTX-loaded stealth liposomes as per the magic gun approach was followed. Stealth liposomes of MTX were prepared by thin-film hydration method using a PEGylated phosph...

This work presents the formulation and characterization of a new product for protection outdoor frescoes from aggressive environmental agents. The is designed as an innovative green coating, prepared through zero-waste one-pot-synthetic method to form silver nanoparticles (AgNPs) directly in chitosan-based medium. AgNPs are seeded grown mixed hydrogel chitosan, azelaic, lactic acid, by reductio...

This study investigated the efficacy of co-deposited vancomycin/chitosan coatings prepared using a plasma process on metallic implants in bacterially challenged rabbit model. A BioDepTM coating was used to deposit thin layers chitosan with vancomycin onto titanium alloy surfaces. Coated were examined standard microscopy, profilometry and elution studies. Nitrided Ti-6Al-4V (Ti alloy) dynamic co...

The efficacy of an edible chitosan coating (CHI; 4 mg/mL) and Origanum vulgare L. essential oil (OVEO; 1.25 μL/mL) for maintaining the quality of cherry tomato fruit during storage at room (25°C; 12 days) and cold (12°C; 24 days) temperatures was assessed. CHI and OVEO in combination showed in vitro fungicidal effects against R. stolonifer and Aspergillus niger. CHI-OVEO coating reduced the inc...

Coating of lignin nanoparticles with chitosan and glucose oxidase allows for the green synthesis acrylic vinyl polymers in Pickering emulsions. The resulting dispersions offer a route to tough composites equipped antioxidant activity.
