microencapsulation as one of the most modern methods has remarkable effects on probiotic survival. in this study lactobacillus casei (atcc 39392) and bifidobacterium bifidum (atcc 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, ph=1.5) and simulated intestina...

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...

Background: The aim of this study was to investigate the effects of chitosan coatings, oregano essential oil, and their combination on microbial quality of chicken fillet during 12 days in refrigerator temperature. Methods: Oregano oil was extracted by water distillation and then different concentrations of oregano oil (1% and 2%) were used for film preparation. Microbiological tests were carri...

The objective of present study was to evaluate the effects of the application of chitosan and chitosan/whey protein on the chemical, microbial and organoleptic properties of Göbek Kashar cheese during ripening time (on 3(rd), 30(th), 60(th) and 90(th) d). Difference in microbiological and chemical changes between samples was found to be significant (p<0.05) during ripening period. Cheese sample...

The effect of coating with irradiated Crab and Shrimp chitosan (CHIirr, Mv = 5.14 × 104) and un-irradiated Crab chitosan (CHIun, Mv = 2.61 × 105) on postharvest preservation of mango (Mangifera indica L.) fruit was studied. Irradiation at 100 kGy and 200 kGy of both Crab chitosan and Shrimp chitosan were used and the fruits were stored at 15°C ± 1°C and 85% relative humidity for 6 weeks. The ef...

Manganese zinc ferrite nanoparticles (MZF NPs) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. To improve the colloidal stability of MZF NPs for biomedical applications, NPs were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (TPP) as crosslinker. The synthesized NPs were characterized by X ray diffraction (XRD) analy...

In this paper, Chitosan-copper nanoparticles were successfully coated onto the Kraft paperusing a dip coating process. First, chitosan-copper nanoparticles solution was prepared byreduction method and the use of ultrasonic radiation. It was employed copper sulphate pentahydrateas precursor salt, NaOH as a reducing agent and Chitosan as capping agent to prepareChitosan-copper nanoparticles solut...

Multilamellar liposomes consisting of dipalmitoyl phosphatidylcholine (DPPC) and dicetyl phosphate (DCP) in a molar ratio of 8:2 (DPPC:DCP = 8:2) were coated with three different types of polymers: chitosan, polyvinyl alcohol having a long alkyl chain, and poly(acrylic acid) bearing cholesterols. The existence of polymer layers on the liposome surface was confirmed by measuring the zeta potenti...
