sustainable fabrication of plant cuticle like packaging films from Tomato Pomace agro waste beeswax and alginate
ACS Sustainable Chemistry & Engineering, 2018Co-Authors: Giacomo Tedeschi, José Jesús Benitez, Luca Ceseracciu, Keyvan Dastmalchi, Boris Itin, Ruth E. Stark, Antonio Heredia, Athanassia Athanassiou, Jose A HerediaguerreroAbstract:Plant cuticles have been used as models to produce hydrophobic films composed of sodium alginate, the fatty acid fraction of Tomato Pomace agrowaste, and beeswax. The fabrication process consisted of the blending of components in green solvents (water and ethanol) and a subsequent thermal treatment (150 °C, 8 h) to polymerize unsaturated and polyhydroxylated fatty acids from Tomato Pomace. When sodium alginate and Tomato Pomace fatty acids were blended, free-standing films were obtained. These films were characterized to evaluate their morphological (SEM), chemical (solid-state NMR, ATR-FTIR), mechanical (tensile tests), thermal (TGA), and hydrodynamic (water contact angle, uptake, and permeability) properties. A comparison between nonpolymerized and polymerized samples was carried out, revealing that the thermal treatment represents a sustainable route to create structured, composite networks of both components. Finally, beeswax was added to the blend with the same amounts of sodium alginate and Tomato p...

Sustainable Fabrication of Plant Cuticle-Like Packaging Films from Tomato Pomace Agro-Waste, Beeswax, and Alginate

Finally, beeswax was added to the blend with the same amounts of sodium alginate and Tomato Pomace fatty acids. The presence of the wax improved the hydrophobicity and the mechanical and water barrier properties as well as decreased the water uptake. These results indicate that polymerized plant cuticle-like films have valuable potential for packaging applications

Sustainable polycondensation of multifunctional fatty acids from Tomato Pomace agro-waste catalyzed by tin (II) 2-ethylhexanoate
Materials Today Sustainability, 2019Co-Authors: José A. Heredia-guerrero, Giacomo Tedeschi, Luca Ceseracciu, Antonio Heredia, Gianvito Caputo, Susana Guzman-puyol, José J. Benítez, Athanassia AthanassiouAbstract:Abstract Bioplastics were prepared from the fatty fraction (i.e., unsaturated and polyhydroxylated fatty acids) of Tomato Pomace agro-wastes. Aliphatic polyesters were synthesized at different temperatures (125, 150, and 175 °C), reaction times (0.25, 0.5, 0.75, 1, 3, 5, and 7 h), and amounts of tin (II) 2-ethylhexanoate (0, 0.02, 0.05, and 0.10 mmol) used as a catalyst. The rate constants and activation energies were calculated from infrared spectra. The right combination of reaction temperature and amount of catalyst improved the reaction kinetics (apparent k from ∼1 to ∼8.5 h−1), whereas the activation energy was reduced from ∼39 without catalyst to ∼28 kJ/mol when tin (II) 2-ethylhexanoate was present. Glass transitions between ca. −25 and ∼0 °C were measured by differential scanning calorimetry, strictly depending on the degree of polymerization. The amorphous character of the samples was confirmed by X-ray diffraction. Young's modulus and hardness were calculated from indentation tests and were typical of soft materials, although increased as the polycondensation reaction progressed. High water-contact angles (maximum value ∼109°) and low water uptakes (minimum value ∼2.1%) were determined. Physical properties were compared with those of common man-made plastics and polymers, finding that these Tomato Pomace bioplastics could be their realistic alternatives.
