“…This effect has been associated with the denaturation of the tertiary and quaternary structures in the proteins, decreasing the polymeric chain rigidity. Similar behavior was observed by Arvanitoyannis et al 3 for gelatin/starch mixtures.…”

Filmes reticulados de gelatina (Gel), caseína (Cas) e a mistura Gel/Cas (1:1, m/m) foram estudados em termos das propriedades térmicas, morfológicas e absorção de água e quanto ao perfil de permeação de p-hidroxiacetanilida (p-HAA ) como fármaco modelo. O grau de reticulação por 1-etil-3-(3-cloridrato) dimetilaminopropil carbodiimida (EDC) foi de 90,6% para filmes de Gel e cerca de 70% para filmes de Cas e misturas Gel/Cas (1:1, m/m). A total solubilidade dos filmes não-reticulados foi reduzida para somente 21 -22% após reticulação com EDC. Apesar do alto grau de reticulação, o intumescimento dos filmes de Gel (87,2%) foi praticamente o dobro do determinado para filmes de Gel/Cas (1:1, m/m) e Cas. A taxa de permeação de p-HAA seguiu a ordem Gel > Gel/Cas @ Cas para filmes reticulados, ou seja, um comportamento consistente com o maior intumescimento da Gel em relação aos outros dois sistemas estudados. Os menores valores de permeação observados para filmes de Cas e Gel/Cas, sugerem que estes sistemas podem ser utilizados para controlar a permeação de fármacos. Considerando os diferentes modelos matemáticos aplicados, os sistemas estudados não mostraram um bom ajuste relativamente a equação de primeira ordem e somente uma parcial correlação com as equações de ordem zero e do modelo de Higuchi. No entanto, uma boa correlação (r 2 > 0,99) foi obtida utilizando a equação da lei das potências (valores de n = 0,70 -0,87), indicando que a permeação de p-HAA através dos filmes foi controlada principalmente pelo mecanismo de difusão.Cross-linked films of gelatin (Gel), casein (Cas) and their (1:1, m/m) mixture (Gel/Cas) were studied in terms of their thermal, morphological and water absorption properties and the permeation profile of p-hydroxyacetanilide (p-HAA) as a model drug. The degrees of cross-linking by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) were 90.6% for Gel films and approximately 70% for Cas and Gel/Cas films. The totally soluble non cross-linked films achieved only 21 -22% of solubility after cross-linking with EDC. Despite the high cross-linking degree, the swelling of Gel films (87.2%) was practically twice that determined for Gel/Cas and Cas films. The permeation rate of p-HAA followed the order Gel > Gel/Cas @ Cas for cross-linked films, which is consistent with the Gel film showing a greater swelling than the other two systems studied. Lower permeation rates were observed for Cas and Gel/Cas films, suggesting that these could be used as rate-controlling systems for drug permeation. For the different mathematical models applied, the systems studied did not show a good fit with the first-order equation and only a partial fit with the zero-order equation and Higuchi's model. However, good correlations (r 2 > 0.99) were obtained using the power law equation (n = 0.70 -0.87), indicating that the p-HAA permeation through the films was mainly controlled by a diffusion mechanism.Keywords: gelatin, casein, films, cross-linking, drug permeation Introduction Gelatin (Gel), which is obtain...

“…In multi-composite gelatin films, however the effect of sorbitol on elongation of film was masked due to interference of chitosan-MMT-gelatin interactions resulting in the reduction of intermolecular spaces between gelatin molecules (p<0.05). A decrease in EAB by incorporation of chitosan was reported by some workers in food grade gelatin and tuna skin gelatin films [16,20]. In addition, the effect of MMT was also noticed in decreasing the EAB of the films (p<0.05).…”

“…Few studies have been initiated to develop biodegradable edible films using fish gelatin by incorporation of nanoclay particles and other natural biopolymers like chitosan, starch and cellulose [16,17]. In our earlier study, multi-composite gelatin films were developed with the addition of MMT and chitosan using sorbitol as a plasticizer [18] but the individual effect of these variable factors on the film properties were not assessed.…”

The effects of four variable factors such as protein, sorbitol, montmorillonite (MMT) and chitosan on the properties of multi-composite shark catfish skin gelatin films were evaluated based on Response Surface Methodology (RSM). Incorporation of chitosan had positive effect on tensile strength, Young's Modulus and water vapor transmission rate (p<0.05). On the other hand, chitosan and MMT had decreased the elongation of the films (p<0.05). The transparency of the gelatin film was increased by the addition of gelatin and chitosan, whereas it was decreased by the addition of MMT. From the present study, it may concluded that gelatin films with good mechanical and barrier properties could be achieved with 4.50% gelatin, 25% sorbitol, 0.37% MMT and 3.25% chitosan. Thus, multicomposite gelatin films with any desirable properties could be formulated based on the results of the response surface methodology and these films shall be suitable for edible films or coatings for fish and other food products in food processing industries.

“…When dissolved in hot water, the crystalline structures of amylose and amylopectin were lost, and the polymers became hydrated. During formation of the film, the starch molecules rearranged themselves by hydrogen bonds, causing embrittlement of the film, which was undesired (Vázquez and Álvarez 2009;Rindlav et al 1997;Arvanitoyannis et al 1997;Arvanitoyannis and Biliaderis 1998;Sothornvit and Krochta 2001;Talja et al 2008). Similar to earlier reports, the unplasticized starch film prepared in this study was very brittle and difficult to peel from the casting surface.…”

A degradable starch/lignin blend film was prepared using corn starch and sodium lignosulfonate via a casting and solvent evaporation method. The effect of sorbitol content on the swelling properties of starch/lignosulfonate blend films was investigated. The effect of lignosulfonate content on the swelling and mechanical properties was also studied. The results showed that when the mass ratio of sorbitol to starch changed over a wide range, from 0:9 to 9:9, the water absorption of the blend films increased at first and then decreased. When the mass ratio of lignosulfonate to starch changed in the same range, the ultimate stress of the blend films decreased markedly, while the water absorption and elongation at break did not show any regular pattern. When the mass ratios of sorbitol to starch and lignosulfonate to starch were both 6:9, the resultant film presented good elasticity and improved hydrophobicity compared to those without lignosulfonate.
