Rheology and processing of gluten based bioplastics

Modelling of pyrolysis and combustion of gluten–glycerol-based bioplastics

“…The volume of the chamber (69 cm 3 ) was filled with approximately 56 g of sample, corresponding to 85% filling ratio. The mixing process was always carried out at 50 rpm (Jerez et al, 2005a). In order to get a bioplastic with suitable mechanical properties, the mixed product was subsequently moulded in a hot-plate hydraulic press, at 100 bar gauge pressure and 140°C (Jerez et al, 2005b).…”

Rheological and structural characterisation of film-forming solutions and biodegradable edible film made from kefiran as affected by various plasticizer types

“…2d). The plateau region has been described in polymer rheology as that in which the cross-links and entanglements within gels prevent any substantial rearrangement of the molecules, hence keeping the ratio of both moduli unchanged [29]. As shown in Fig.…”

Influence of sorbitol on mechanical and physico-chemical properties of soy protein-based bioplastics processed by injection molding

“…Protein-based bioplastics can be processed by using existing processing technologies, from the physicochemical [7] to thermomechanical methods (compression molding, thermomolding and extrusion) [8] . However, injection molding, which is the most common processing method used with synthetic polymers, has been poorly used for protein-based bioplastic applications [9] .…”

“…The use of injection-molding technique to produce protein-based bioplastics enable the manufacture of many kinds of shaped products, which entails new arguments in favor of considering these biodegradable polymers as an alternative to synthetic polymers. This technique has been previously used for the elaboration of crayfish-based bioplastics [10] , pea-based bioplastics [11] , albumen-based [8] bioplastics or soy-based bioplastics [12] , among others. However, glycerol has been used as the only plasticizer in these works and sorbitol has not previously tested.…”
