Plastic materials for food packaging are being replaced by biodegradable films based on biopolymers due to the adverse effects they have had on animal life and the environment. In this study, nanocomposite films containing 2.5 wt% sodium caseinate and 2 wt% glycerol were reinforced with 0.1 or 0.2 wt% nano TiO2 prepared in two forms: spheres (P25) and tubes. The effects of nanoreinforcement geometry...
Perturbations in the native structure, often caused by stressing cellular conditions, not only impair protein function but also lead to the formation of aggregates, which can accumulate in the cell leading to harmful effects. Some organisms, such as plants, express the molecular chaperone HSP100 (homologous to HSP104 from yeast), which has the remarkable capacity to disaggregate and reactivate proteins...
Biodegradable biopolymers are currently being studied as replacements for their non‐biodegradable counterparts used for food packaging today. In this regard Roberto Jorge Candal, María Lidia Herrera and team report on nanocomposite films containing sodium caseinate and glycerol reinforced with spherical or tubular TiO2 nanoparticles. The geometry of the particles is seen to affect both their distribution...
