“…Water solubility observed in this study was similar to that reported in the literature for gelatin films. Alves et al (2011) evaluated the solubility of gelatin films and polyvinyl alcohol and found values between 46.2 and 47.7%, and Bodini (2011) studied the use of gelatin films with PEE and found values of about 31.1%.…”

“…PVA is a nontoxic, biodegradable, synthetic, water-soluble polymer with outstanding chemical stability and good film-forming capacity [18,19]. PVA-protein films are produced as materials for food packing, tissue engineering, and drug delivery systems [20][21][22][23]. PVA hydrogel materials containing keratin from wool and hair were recently synthesized by electron beam irradiation [24].…”

“…To improve the mechanical properties, moisture sensitivity, and thermal stability of these protein/PVA blend films, the polymers were cross-linked with glutaraldehyde. Glutaraldehyde interacts with both PVA and the protein and binds them together [20,25]. However, there are always concerns about the toxicity of glutaraldehyde residuals in materials, which limits the application of glutaraldehyde in the biomaterial and food packing industries [26].…”

Feather keratin (FK) extracted from feathers represents a valuable source of biodegradable and biocompatible polymer. The aim of this study was the development and characterization of blended films based on FK and polyvinyl alcohol (PVA) cross-linked by dialdehyde starch (DAS) for a potential drug release application. The compatibility of FK/PVA was improved when cross-linked by DAS: the relative crystallinity of the PVA/FK film slightly decreased, and the enthalpy value for the melting peak decreased by about 50% for the cross-linked films. The total soluble mass of all blend films in water was below 35% at 37 °C, indicating a good stability of the films in water. The results of the Rhodamine B dye (as a model drug) release tests showed that the release rates decreased with increasing DAS content. DAS-induced cross-linking improves several important properties of the FK/PVA films, such as the compactness, the compatibility, and the stability in water. These improvements offer the potential to expand the application of FK films in the biomaterial field. OPEN ACCESSPolymers 2015, 7 581

Innovations in the food industry are shaped both by new technologies available and by society's requirements. A good knowledge on the chemistry and biological role of the macro-nutrients (proteins, carbohydrates, lipids and also energy and water) and micronutrients (minerals and vitamins) is required. Food production foundations include not only the design of the food products but also the materials, mechanics, ingredients, conversion and transformation all must be taken into consideration. Edible polymers are polymeric materials that can be easily consumed by human beings or lower animals in whole or part via the oral cavity and given harmless effect to the health. An edible polymer is originated from natural products such as polysaccharides, proteins and lipids, with the addition of plasticizers and surfactants. Radiation-processing technologies are used currently for numerous applications of commercial and economic importance, but it is an emerging application with the use of ionizing radiation to enhance properties of edible polymers such as carbohydrates or proteins. This chapter aims at supplying the state of the art about the effects of ionizing radiation on edible polymers: starch and vegetal proteins and also on gelatin that comes from animal origin.
