“…Al-Hassan & Norziah (2012) found low values for TS sago starch-gelatin films (1.28 to 1.70MPa). Valderrama & Gante (2014) found similar values of TS (2.76 to 5.34MPa) for films based on blue corn flour with glycerol and also observed that the increase in glycerol content decreased the tensile strength. Polysaccharides and protein-polysaccharides based films with glycerol are more stretchable and flexible due to the plasticization effect that increases the mobility of polymer chains (Valderrama & Gante, 2014).…”

The values obtained were higher than the value found for polypropylene films (60%) (Krochta & DeMulder, 1997).…”

Effect of incorporation of nutraceutical capsule waste of safflower oil in the mechanical characteristics of corn starch films

et al. 2016

Biodegradable films blends made of safflower oil nutraceutical capsules waste: corn starch (20:4, 30:4, 40:4 and 50:4) were prepared. The objective of this study was to evaluate the influence of addition of different concentrations of safflower oil nutraceutical capsule waste in the mechanical properties (tensile strength, elongation at break, Young's modulus) and thickness of corn starch films. A decrease in tensile strength and Young's modulus and an increase in elongation at break were observed with the increase in the content of the nutraceutical capsule waste. The results showed that the blends of safflower oil capsules waste-corn starch films demonstrated promising characteristics to form biodegradable films with different mechanical characteristics.

Thermoplastic starch (TPS)/polycaprolactone (PCL) blends were obtained by melt mixing. First, the best formulation of thermoplastic starch (starch, plasticizer and additives) was studied. The obtained films were characterized by means of differential scanning calorimetry, DSC (melting temperature and crystallinity degree); thermogravimetric analysis, TGA (real composition of the blend and thermal stability); tensile tests (mechanical properties); infrared spectroscopy, FTIR (interactions between components); scanning electron microscopy, SEM (morphology); and water absorption tests. The effect of PCL/TPS ratio on the previously mentioned characteristics and properties were studied. In addition, the effect of using PCL modified with maleic anhydride as compatibilizer was also analyzed. An optimal compatibilizer content was found improving the mechanical properties and slowing down the degradation rate in soil of the blends. On the other hand, a slight increase in the water absorption of the blends was found in comparison with the noncompatibilized ones.

“…Biobased polymers such as polysaccharides, proteins, lipids, PLA and PHA have gained significant attention for the development of environmentallyfriendly food packaging materials to surrogate their nonbiodegradable polymer counterparts (Guilbert et al 1996;Gennadios et al 1997;Krochta and De Mulder-Johnston, 1997;Cuq et al 1998;Rhim and Ng 2007). They have secured increasing focus owing to their numerous inherent advantages such as renewability, sustainability, biocompatibility, biodegradability, compostibility, processability and less energy dependence during processing (Grenha et al 2010;Rasal et al 2010;ValderramaSolano and Rojas de Gante 2014). Recent technological innovations and the inbuilt properties of biobased plastics films fuelled their accelerating usage as suitable food packaging materials (Cha and Chinnan 2004).…”

Biobased food packaging materials are gaining more attention owing to their intrinsic biodegradable nature and renewability. Selection of suitable biobased polymers for food packaging applications could be a tedious task with potential mistakes in choosing the best materials. In this paper, an expert system was developed using Exsys Corvid software to select suitable biobased polymer materials for packaging fruits, dry food and dairy products. If -Then rule based system was utilized to accomplish the material selection process whereas a score system was formulated to facilitate the ranking of selected materials. The expert system selected materials that satisfied all constraints and selection results were presented in suitability sequence depending on their scores. The expert system selected polylactic acid (PLA) as the most suitable material.
