Complications in dentistry and orthopaedic surgery are mainly induced by peri-implant bacterial infections and current implant devices do not prevent such infections. The coating of antibacterial molecules such as chitosan on its surface would give the implant bioactive properties. The major challenge of this type of coating is the attachment of chitosan to a metal substrate. In this study, we ...

in this study, the effect of gelatin-chitosan edible coating on the quality of chicken breast during 9 days of refrigerated storage (4 was investigated. three concentrations of gelatin (3, 6 and 8% w/v) and two concentrations of chitosan (1 and 2% w/v) were used to prepare the coating materials. samples was divided in 7 group, no coating (control), gelatin 3% and chitosan 1% (sample 2), gelatin...

Coating of gelatin and chitosan can improve fish fillet's quality, but the mechanism is not clear. Chitosan/gelatin coatings significantly prevented deterioration of golden pomfret fillet at 4 °C. Chitosan with 7.2% gelatin group showed the best effect on preserving the length of myofibril, which remained greater than 15 μm at day 17 of storage, while for control, chitosan and chitosan combined...

abstract:any effects of wood coating with different compounds as nano-zinc, nano-chitosan, chitosan, silicon oil and flaxseed oil on surface properties as; wood color change, surface roughness and wettability were studied in the current research work. for this purpose, sample boards of beech wood were cut into sizes of 2×10×20cm. the specimens were coated with the noticed coatings and tested fo...

The quality attributes and storage life of ‘Jinhwang’ mango fruit can be effectively maintained with 1-methylcyclopropene (1-MCP) application and/or chitosan coating. ‘Jinhwang’ mango fruit was treated with 5 μl l 1-MCP for 12 h, dipped with 0.5 % chitosan, 5 μl l 1-MCP combine with 0.5 % chitosan and untreated (control) then stored at 10C. Mango treated with 1-MCP maintained firmness, sucrose ...

BACKGROUND Absorption of antigens onto chitosan microparticles via electrostatic interaction is a common and relatively mild process suitable for mucosal vaccine. In order to increase the stability of antigens and prevent an immediate desorption of antigens from chitosan carriers in gastrointestinal tract, coating onto BSA loaded chitosan microparticles with sodium alginate was performed by lay...

Introduction: This study was conducted to evaluate the influence of chitosan Nano-gel/emulsion coating functionalized by Ziziphora clinopodioides essential oil (ZCEO) and nisin on growth inhibition of Escherichia coli O157: H7 inoculated in beef samples during 16 days in cold storage condition (4˚C). Methods: Beef sample ...

This study was conducted to investigate the efficacy of antimicrobial coatings for inactivation of Salmonella on the surface of tomato stem scars. Scars were inoculated with a four-strain cocktail of Salmonella (serovars Montevideo, Newport, Saintpaul, and Typhimurium) and coated with acid-chitosan solutions. The chitosan coating with three acids (3A plus chitosan), the chitosan coating with o...

The chitosan-based coating with antimicrobial agent has been developed recently to control the decay of fruits. However, its fresh keeping and antimicrobial mechanism is still not very clear. The preservation mechanism of chitosan coating with cinnamon oil for fruits storage is investigated in this paper. Results in the atomic force microscopy sensor images show that many micropores exist in th...

A novel kind of functional sutures was developed by combining electrospinning with a braiding technique. After post treatments, the electrospun PLLA nanofiber threads which were collected uniaxially were made into a more compact braided wire. Chitosan was used as a coating agent to make the braided wire surface smoothened and functionalized. Morphology and mechanical properties of the PLLA sutu...
