The choice of drug therapy in pregnant patients suffering from vaginal infections is limited by the safety profile of the drug. Assuring the efficient topical therapy to avoid systemic absorption is considered the best therapy option. Chitosan-coated liposomes have been developed and optimized to assure localized therapy of clotrimazole. Chitosan was selected as mucoadhesive polymer both to pro...

The effects of chitosan (2%) coating combined with green tea extract (GTE) (1%) on the quality of tiger-tooth croaker (Otolithes ruber) fillets including chemical, microbiological, texture, color and sensory properties during 16 days of refrigerated storage was investigated. The color changes were significantly retared, and the texture parameteres and sensory scores were significantly improved ...

in this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). following treatments, fruits were stored at 0?c and 80 ? 2% relative humidity for 25 days. the weight loss, total soluble solids (tss), titratable acidity (ta)...

Chitosan has attracted much interest due to its special physical and chemical properties related to immunochemistry. The aim of this commentary is to appraise chitosan as an attractive functional polymer for medicine applications, which contributes to the development of chitosan for the immunochemistry. As reported, Chitosan has been used for immunochemistry purpose, such as functional food for...

Objective(S): The chitosan - Fe3O4 core - shell nanoparticles were synthesized. The nanoparticles should be coated properly in the shape of core-shell, so that they remain hidden from the body's immune system after coating. Effects of different molecular weight in coating were investigated. Methods: Nanoparticles coated with low and ...

Beef is susceptible to rapid spoilage due to its high amount of protein (18.00%) and moisture (72.00%). Food industries have recently found methods to extend beef shelf-life. The influence of beef dipping in hydro-alcoholic extract of sumac (SE) and chitosan (CH) coating incorporated with Zataria multiflora essential oil (ZEO) on microbial, chemical and sensory quality of beef was eval...

Nanospheres are being developed for the oral delivery of peptide-based drugs such as insulin. Mucoadhesive, biodegradable, biocompatible, and acid-protective biomaterials are described using a combination of natural polyelectrolytes, with particles formulated through nanoemulsion dispersion followed by triggered in situ gel complexation. Biomaterials meeting these criteria include alginate, dex...

Antimicrobial packaging is one of the most promising active packaging systems. Antimicrobial packaging is the packaging system that is able to kill or inhibit spoilage and pathogenic microorganisms that are contaminating foods. A tremendous effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservati...

This study investigates the production of alginate microcapsules, which have been coated with the polysaccharide chitosan, and evaluates some of their properties with the intention of improving the gastrointestinal viability of a probiotic ( Bifidobacterium breve ) by encapsulation in this system. The microcapsules were dried by a variety of methods, and the most suitable was chosen. The work d...
