“…Furthermore, PCL degraded completely at the final test temperature, while for neat TZ we observed a final residue equal to 8.8% (Table 2). The presence of a residual mass at temperatures higher than 450°C was also reported by Sessa et al for melt-processed corn zein [23] and by Mariani et al for corn starch blends [24] and, has been ascribed to inorganic compounds derived from thermal degradation [23,24]. By considering the material formulations used (Table 1) and the TGA results (Table 2), we may conclude that the final residues of PCL-TZ-HA 10 and PCL-TZ-HA 20 at 600°C well matched the nominal HA amount within the composites.…”

The aim of this study was the design of novel biodegradable porous scaffolds for bone tissue engineering (bTE) via supercritical CO 2 (scCO 2 ) foaming process. The porous scaffolds were prepared from a poly(ε-caprolactone)-thermoplastic zein multi-phase blend w/o interdispersed hydroxyapatite particles (HA) and the porous structure achieved via the scCO 2 foaming technology. The control of scaffolds porosity was obtained by modulating materials formulation and foaming temperature (T F ). The scaffolds were subjected to morphological, micro-structural and biodegradation analyses, as well as in vitro biocompatibility tests. Results demonstrated that both HA concentration and T F significantly affected the micro-structural features of the scaffolds.In particular, scaffolds with porosity and pore size distribution, mechanical properties and biodegradability adequate for bTE were designed and produced by selecting a T F equal to 100°C for all the compositions used. The biocompatibility of these scaffolds was assessed in vitro by using osteoblast-like MG63 and human mesenchymal stem cells (hMSCs).

“…The processing conditions were observed to affect the thermo-mechanical performances of the blends. Mariani et al [107] prepared and characterized the thermal, mechanical and morphological properties of blends based on PCL and modified corn starch, with added soy protein isolate (SPI) and sorbitol. The insertion of soy protein isolate in the formulations was done with the aim of balancing the C/N ratio of the blend, which plays a key role in the biodegradation process of these materials.…”

State of the Art in the Development and Properties of Protein-Based Films and Coatings and Their Applicability to Cellulose Based Products: An Extensive Review

Abstract:There is increasing research towards the substitution of petrochemicals by sustainable components. Biopolymers such as proteins, polysaccharides, and lipids derive from a variety of crop sources and most promisingly from waste streams generated during their processing by the agro food industry. Among those, proteins of different types such as whey, casein, gelatin, wheat gluten, soy protein or zein present a potential beyond the food and feed industry for the application in packaging. The general protein hydrophilicity promotes a good compatibility to polar surfaces, such as paper, and a good barrier to apolar gases, such as oxygen and carbon dioxide. The present review deals with the development of protein-based coatings and films. It includes relevant discussion for application in paper or board products, as well as an outlook on its future industrial potential. Proteins with suitable functionalities as food packaging materials are described as well as the different technologies for processing the coatings and the current state of the art about the coating formulations for selectively modulating barrier, mechanical, surface and end of life properties. Some insights onto regulations about packaging use, end of life and perspectives of such natural coating for decreasing the environmental impact of packages are given.

Protein is a by-product of rice starch production. The major component of rice protein found in endosperm is glutelin, an alkali-soluble protein. Pure glutelin film could not peel off from the casting plate; however, glutelin films containing starch were easily removed from the plate. Various ratios of rice starch and glutelin at 100:0, 92:8, 75:25, 50:50 and 25:75 (w/w) were applied for casting film. Sorbitol was used as a plasticizer. Morphology was studied by scanning electron microscope. The mechanical properties and water vapor permeability (WVP) were evaluated. The results were found that rice starch and glutelin-based composite films became thinner with smoother surface as starch content increased. Elongation and flexibility of composite films containing glutelin could be improved by incorporation of rice starch at a considerable amount without affecting on tensile strength and WVP. PRACTICAL APPLICATIONSThis research had an objective to study the surface morphology, mechanical properties and WVP of composite films based on glutelin (by-products from producing rice starch) and rice starch. Those properties are important for the applications used as edible films/coatings. Edible films and coatings could be used to protect the product from mechanical damage, physical and chemical. In this paper, we did not add any antimicrobial agent. So, this film cannot protect the product from microbiological activities. The applications of edible films and coating have been successfully applied in fresh foods and processed foods.
