“…These results suggest that the loss of soluble matter corresponds basically to the hydrophilic character of GL and W (liquid plasticizer used), which are easily release into the medium. These results are similar to other previously obtained, and also were attributed to the loss of plasticizer [9,11] . Finally, the swelling ratio is very similar for the systems containing GL, regardless of the presence of SB.…”

“…As it may be observed, all probes have a remarkable a high water uptake ability, which is related to the abundance of hydrophilic group in the SPI system. In fact, the value reached is much higher than those previously reported for albumen-based bioplastics or soy [9,12] . The use of SB as plasticizer seems to give raises an increase in water uptake after 24h, which is probably related to the high hydrophilicity of this solid sugar alcohol.…”

“…This behavior has been previously related to a glass-like transition [9] . The unimodal profiles indicate a good compatibility, between protein isolate and the different plasticizers, for all the systems after the injection molding process, regardless of the plasticizer used (GL, GL/SB or W/SB).…”

“…However, injection molding, which is the most common processing method used with synthetic polymers, has been poorly used for protein-based bioplastic applications [9] . This technique would suffer a remarkable demand if the feasibility of performing protein-based materials were demonstrated.…”

SbstractSoy Protein Isolate (SPI) has been evaluated as useful candidate for the development of protein-based bioplastic materials processed by injection molding. The influence of sorbitol (SB) as plasticizer in mechanical properties and water uptake capacity was evaluated in SPI-based bioplastics. A mixing rheometer that allows monitoring torque and temperature during mixing and a small-scale-plunger-type injection molding machine were used to obtain SPI/Plasticizer blends and SPI-based bioplastics, respectively. Dynamic measurements were carried out to obtain mechanical spectra of different bioplastics. Moreover, the mechanical characterization was supplemented with uniaxial tensile tests. Additionally, the influence of SB in water uptake capacity was also evaluated. The introduction of SB leads to increase the rigidity of bioplastics as well as the water uptake capacity after 24h, however it involves a decrease in strain at break. Final bioplastics are plastic materials with both adequate properties for the substitution of conventional petroleum plastics and high biodegradability.

“…The bioplastics obtained would be suitable to replace conventional plastics in food packaging. Natural biodegradable polymers represent a particular interest owing to the compostability of the final packaging films obtained, since most of these products have a relatively short service life ending up in landfills . In this sense, protein‐based materials have been proved to be completely degraded in 50 days when buried in farmland soils …”

Two well‐known proteins have been selected in order to produce bioplastics through injection molding: a soy protein isolate (SPI) and an egg white albumen concentrate (EW). Each of them has been thoroughly mixed with glycerol (40 wt %) and the blend then obtained have been characterized by means of rheological and thermomechanical techniques, which allowed the optimization of the processing moulding conditions (cylinder temperature, 60°C–65°C; mould temperature, 120°C; post‐injection pressure, 500–600 bars). Once bioplastics were obtained, their thermomechanical and tensile properties, as well as their water uptake capacity and transparency were evaluated. Bioplastics containing EW showed higher values in the elastic and loss moduli, E′ and E″, from −30°C to 130°C, than the corresponding SPI bioplastic. However, they both showed qualitatively the same evolution with temperature, where E′ and E″ decreased up to a plateau at high temperatures. When examining their tensile and water uptake properties is found that SPI bioplastics are more ductile and present enhanced water uptake behavior over EW bioplastics, which on the other hand possess higher Young's modulus. SPI seems to provide tougher bioplastics, being an excellent option for potential superabsorbent applications, whereas EW would suit for those applications requiring higher mechanical properties. © 2015 Wiley Periodicals, Inc.
