“…Petroleum based plastics are dominantly used in packaging industries owing to their outstanding versatility, mechanical and barrier properties (Farris et al 2009;González and Alvarez Igarzabal 2013;Siracusa et al 2008;Tharanathan 2003). In spite of their numerous advantages, petroleum based plastics area great source of environmental pollution, as they are non-biodegradable.…”

In this study, sugar palm starch (SPS) films were developed using glycerol (G), sorbitol (S) or their combination (GS) as plasticizers at the ratio of 15, 30 and 45 (wt)% using casting technique. The addition of plasticizers to SPS film-forming solutions helped to overcome the brittle and fragile nature of unplasticized SPS films. Increased plasticizer concentration resulted to an increase in film thickness, moisture content and solubility. On the contrary, density and water absorption of plasticized films decreased with increasing plasticizer concentration. Raising the plasticizer content from 15 to 45 % showed less effect on the moisture content and water absorption of S-plasticized films. Films containing glycerol and glycerol-sorbitol plasticizer (G, and GS) demonstrated higher moisture content, solubility and water absorption capacity compared to S-plasticized films. The results obtained in this study showed that plasticizer type and concentration significantly improves film properties and enhances their suitability for food packaging applications.

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

“…Sin embargo, otros biopolímeros se caracterizan por el bajo rendimiento de producción y los altos costos que representa elaborarlos, lo que ha limitado la aplicación de algunos de estos en ciertos sectores industriales y se ha convertido en un reto para los investigadores [22]. Entre los biopolímeros que tienen aplicación específica en empaques de alimentos, están los almidones y celulosas de diversas fuentes [11,26], zeína de maíz y proteína de soja [24]; también sobresalen las mezclas entre proteína de soja con ácido poliláctico (PLA) [27], proteína de suero de leche como recubrimiento de películas de PLA [28], quitosano combinado con polímeros resistentes al agua [29], FS y PVA [30], quitosano y FS [9], entre otros.…”

RESUMENEl cuidado del medioambiente y el uso responsable de los recursos, ha promovido investigaciones con diferentes biopolímeros que permitan el desarrollo de nuevos materiales que puedan ser empleados en empaques para alimentos. Entre estos biopolímeros se encuentra la fibroína de seda (FS), que representa cerca del 70% de la fibra de seda y puede ser obtenida a partir de capullos de primera calidad o de los desperdicios generados en la producción serícola. En el desarrollo de empaques de alimentos con FS, se pueden dar dos alternativas de producción, una en la que la FS puede ser funcionalizada por otros componentes, y otra en la que se incluye la FS como componente funcional modificando otros biopolímeros. La FS puede conferirle al material de empaque ciertas propiedades, como: aumento de la permeabilidad de oxígeno, resistencia a la rotura y una mayor velocidad de degradación del biopolímero. Este artículo se centra en cuatro temas principales: empaques, biopolímeros en empaques, FS y finalmente, la FS en empaques para alimentos.Palabras clave: Empaques, Materiales poliméricos, Biopolímeros, Fibroína de seda, Biomateriales. ABSTRACTEnvironmental protection and responsible use of resources, have promoted research of different biopolymers allowing to develop biodegradable materials which can be used in food packaging. Among these biopolymers is silk fibroin (SF), this protein represents nearly 70% of the silk fiber and it can be obtained from high quality cocoons or from waste generated in the silk industry. In the development of food packaging with SF, there are two possible alternative of production, one in what the SF can be functionalized by other components and another in which, the FS is included as functional component modifying other biopolymers. In the case of food packaging, the SF can concede desirable properties to the package such as an increase in oxygen permeability, more tensile strength and a higher biopolymer degradation rate. This paper is focused on four main topics: packaging, biopolymers in packaging, SF and finally, the SF in food packaging.
