“…1. The WVP value of bilayer was the lowest as compared with monolayer films at day 0, with values of 156.9, 290.5, 224.6 g mm m −2 d −1 kPa −1 , respectively, which was coherent with the study of Jridi et al [24] The result indicated that the interfacial interaction among PVA, CHI, and SA led to the formation of a more close-knit matrix, and the transfer of water molecules through the network was limited. WVP is an important parameter for food packaging, with low value representing better water barrier ability, which is a benefit for the preservation effect.…”

The composite bilayer film based on polyvinyl alcohol, sodium alginate, and chitosan were developed in this study, and the effects of the related coating on internal-quality changes of salted duck eggs (SDEs) during storage were determined. The results showed that the overall properties of the bilayer film were better than those of monolayer films, including storage stability. Coatings could significantly (p < 0.05) reduce quality deterioration of SDEs such as water loss, oil exudation, and gritty. The bilayer coating was more effective in inhibiting the increase of egg yolk pH and total bacterial counts than monolayer coatings. After storage for 60 days, water content of bilayer coated SEDs was 19.7% higher than that of the control SDEs, oil exudation was 38% higher, and gritty texture was 27.9% higher. Moreover, bilayer coating could prolong the shelf life of SDEs to more than 60 days at 25°C and 50% relative humidity according to the results of total bacterial count experiment, while the shelf life of control SDEs was less than 45 days. This study indicated the potential application of bilayer composite coating for preservation of SDEs. ARTICLE HISTORY

“…Ionic and hydrogen bonding interactions of chitosan and PC may be explained by the high tensile strength and elongation of PC1Cs2 compared to NPC/Cs2 and since chitosan provides film forming property in these formulations, the higher strength and elasticity of PC1Cs2 compared to PC2Cs2 could be because of higher ratio of chitosan to PC in this formulation. Presence of drug crystals may be the reason for brittleness and lower TS and EB of NPC/Cs2 as well (3,10,24).…”

Background:Griseofulvin is an antifungal drug and is available as oral dosage forms. Development of topical treatment could be advantageous for superficial fungal infections of skin. The film forming property of chitosan has made it interesting for transdermal/ dermal drug delivery, but showed lack of stability. Soy phosphatidylcholine (PC), besides playing penetration enhancer and solubilizer roles, could enhance the stability and mechanical properties of the film. Films prepared from a mixture of chitosan and PC can achieve the benefits of both materials. Objectives: The aim of this study was to prepare and characterize films formed from blends of chitosan and soy PC for topical delivery of griseofulvin. Materials and Methods: Topical films composed of chitosan and soy PC were prepared by means of casting and solvent evaporation technique. The properties of the films were characterized regarding mechanical properties, swelling, ability to transmit vapor, drug release, thermal behavior and antifungal efficacy against Microsporum gypseum and Epidermophyton floccosum. Results: Presence of soy PC improved mechanical properties, lowered swelling ratio and increased stability of the films. Solubilizing activity of phospholipid resulted in higher flux of drug release from formulation containing higher amount of soy PC. Antifungal efficacy of formulations was confirmed against two species of dermatophytes in vitro. Conclusions: This topical composite film had the potential for griseofulvin delivery to superficial fungal infections.

Effect of the Addition of Carnauba Wax on Physicochemical Properties of Chitosan Films

et al. 2017

View full text Add to dashboard Cite

Films and edible coatings of natural polymers have been proposed as an attractive alternative for conventional plastic packaging because of their excellent biodegradability and biocompatibility. However, natural polymers, like chitosan, are hydrophilic and present poor water barrier properties. The addition of wax or other hydrophobic substances decreases water permeability of natural polymers but can increases their opacity.The objective of this work was to produce biofilms based on chitosan and different concentrations of carnauba wax and analyze their optical and barrier properties. The films were obtained by dissolving chitosan in acetic acid. Carnauba wax was incorporated into filmforming solutions at0, 15, 30, 40 and 50% (w/w). The opacity increased with higher concentrations of wax, the film with 50% of wax showed the highest value with an increase of 10.5% compared to the control film. The water vapor permeability decreased from 2.73 g.mm/kPa.m 2 .h (0% of wax) to 0.77 g.mm/h.kPa.m 2 (40% of wax). The solubility decreased to about 60% over the control films, and the contact angle increased from 53º to 83º, in film with 0 and 50% of wax, respectively.
