“…PDO was intensively used as a plasticizer material in the composition of biodegradable films, fibers, and plastics of Sorona family (PTT-based plastic materials) [68]. A study conducted by González et al in 2017 used PDO and D-isosorbide as a green plasticizer for starch-based biofilms, and evaluated the plasticizer effect on aging (two weeks) [69]. It appeared that biofilms containing PDO presented significant evolution in terms of mechanical properties and contact angle values during storage [69].…”

In the current work the physicochemical features of poly(vinyl alcohol) (PVOH) biofilms, enriched with eco-friendly polyols and with carotenoid-rich extracts, were investigated. The polyols, such as glycerol (Gly), 1,3-propanediol (PDO), and 2,3-butanediol (BDO) were used as plasticizers and the tomato-based pigments (TP) as coloring agents. The outcomes showed that β-carotene was the major carotenoid in the TP (1.605 mg β-carotene/100 DW), which imprinted the orange color to the biofilms. The flow behavior indicated that with the increase of shear rate the viscosity of biofilm solutions also increased until 50 s−1, reaching values at 37 °C of approximately 9 ± 0.5 mPa·s for PVOH, and for PVOH+TP, 14 ± 0.5 mPa·s in combination with Gly, PDO, and BDO. The weight, thickness, and density of samples increased with the addition of polyols and TP. Biofilms with TP had lower transparency values compared with control biofilms (without vegetal pigments). The presence of BDO, especially, but also of PDO and glycerol in biofilms created strong bonds within the PVOH matrix by increasing their mechanical resistance. The novelty of the present approach relies on the replacement of synthetic colorants with natural pigments derived from agro-industrial by-products, and the use of a combination of biodegradable polymers and polyols, as an integrated solution for packaging application in the bioplastic industry.

“…The transparency of a film is an interesting parameter to bare in mind, because it can determine the field of application. For example, high transparency may be required for food packaging because it enables the product to be appreciated visually [47,48] and may reduce the antimicrobial charge of packaged food [49]. By contrast, films of low transparency can increase the shelf life of packed products [50].…”

Starch films are gaining attention as substitutes of synthetic polymers due to their biodegradability and low cost. Some ionic liquids have been postulated as alternatives to glycerol, one of the best starch plasticizers, due to their great capacity to form hydrogen bonds with starch and hence great ability of preventing starch retrogradation and increasing film stability. In this work, [emim + ][Ac-]-plasticized starch films were prepared from potato, corn and wheat starch. The effect of starch molecular structure in terms of granular composition (amylose and phosphate monoester contents) and molecular weight (Mw) on film properties was evaluated. Potato starch films were the most amorphous because of the higher Mw and phosphate monoester content of potato starch, both contributing to a lower rearrangement of the starch chains difficulting the crystallization process. In contrast, corn and wheat starches lead to more crystalline films because of their lower Mw, which may imply higher mobility and crystal growth rate, and lower phosphate monoester content. This more crystalline structure could be the responsible of their better mechanical properties. [emim + ][Ac-] can be considered suitable for manufacturing starch films showing corn and wheat starch films similar properties to synthetic low-density polyethylene, but involving a simple and environmentally-friendly process.

“…This result differs from those reported in starch films once the reduced interaction between glycerol and amylopectin generates free hydroxyls that favor water absorption, increasing the hydrophilic nature and the humidity of films (Flores, Famá, Rojas, Goyanes, & Gerschenson, 2007;Hu, Chen, & Gao, 2009;Garcia et al, 2009). Moreover, films with high humidity hinder the components interaction, thus decreasing the degradation temperature, affecting their thermal stability and commercial life span (González et al, 2017;Gutierrez et al, 2015).…”

The goal of the present study was to determine, through full 2 3 factorial design, the optimum process conditions to develop a biodegradable film, made from gelatin with buriti oil (BO) as additive, characterizing their physical, mechanical, and antioxidant aspects. The conditions for the optimization were 2.3% of fish gelatin, 30% of BO, and 13.18% of plasticizer. The films produced under this condition presented high antioxidant activity (24.77 µmol de TE/g), mechanical resistance (8.04 MPa), and satisfactory water vapor permeability (WVP; 0.38 × 10 −10 g.m. m −2 . s −1 . Pa −1 ). The film presented low solubility in water, low humidity, and low water activity, contributing to its integrity, without identifiable flaws. The increase in the concentration of BO provided higher antioxidant properties to the films and the reduction in gelatin and glycerol concentrations provided lower WVP, increasing the traction resistance.Desarrollo y optimización de una película compuesta hecha de gelatina de pescado biodegradable con aceite de burití añadido RESUMEN A través de un diseño factorial completo de 2 3 , el presente estudio se propuso determinar las condiciones óptimas para desarrollar una película biodegradable, hecha de gelatina con aceite de burití añadido, y caracterizar sus aspectos físicos, mecánicos y antioxidantes. Se pudo constatar que las condiciones óptimas para este proceso incluyen el uso de 2.3% de gelatina de pescado, 30% de aceite de burití y 13.18% de plastificante. Las películas producidas bajo estas condiciones presentan elevada actividad antioxidante (24.77 µmol de TE/g), resistencia mecánica (8.04 MPa) y WVP satisfactoria (0.38 × 10 −10 g.m. m −2 . s −1 . Pa −1 ). Además, la película mostró tener baja solubilidad en el agua, baja humedad y baja actividad en agua, lo cual contribuye a mantener su integridad, sin que se presenten defectos identificables. Al elevarse la concentración de aceite de burití, las películas acusaron propiedades antioxidantes más elevadas. Una reducción de las concentraciones de gelatina y glicerol produjo una permeabilidad más baja al vapor de agua, aumentando la resistencia a la tracción. ARTICLE HISTORY
