abstract = {Posidonia oceanica biomass has been valorized to produce cellulosic nanocrystals with different purification degrees at lab- and pilot plant-scale. The cellulosic nanocrystals (10 % and 20 % (w/w)) were incorporated into corn starch, producing biocomposite films by melt mixing and hot-pressing at lab-scale. Biocomposite films showed remarkable improvements on the mechanical and water barrier performance (up to 10-fold increase in the elastic modulus and 2-fold decrease in the water permeability). Biocomposite packaging structures were also produced at pilot plant-scale by extrusion and thermoforming. Adjusting the plasticizer formulation and increasing the nanocrystals’ loading up to the maximum enabling good processability (10 % (w/w)) allowed the production of trays with enhanced water barrier and mechanical performance, which, unlike the pure starch, kept their shape upon storage. These results highlight the potential of P. oceanica nanocrystals to improve the performance of starch-based packaging structures and demonstrates the potential of the production process to be industrially applied.},

abstract = {Posidonia oceanica waste biomass has been valorized to develop bioactive multifunctional cellulosic aerogels (HCAG) by simpler and greener protocols. Hydrophobization of cellulosic aerogels was achieved through PLA coating, while bioactivity was imparted by the incorporation of hydrophilic (E2) and hydrophobic extracts (E3) produced from the same biomass. The incorporation of extracts led to denser aerogels, with less porous structures. These aerogels showed outstanding water and oil sorption capacities (1500–1900%), being able to release the adsorbed liquid almost completely after 7 days. Interestingly, all the aerogels showed a positive inhibition effect (23–91%) on the β-carotene bleaching assay. Moreover, the aerogels loaded with extracts, especially when combining E2 and E3, were able to reduce the oxidation of lipids and oxymyoglobin in red meat after 10 days of storage. This evidences the potential of these multifunctional aerogels as bioactive adsorbing pads to preserve the quality of fresh packaged foods.},
