“…The characteristic bands at 1639 and 1546 cm -1 (non-treated and scCO 2 -treated G/Ch 50:50 ) correspond to Amide-I, representing C=O stretching vibration coupled with C-N stretch, and Amide-II, bending vib-ration of N-H groups and stretching vibration from C-N groups, respectively (Figure 4, spectra (a) and (b)) [23]. In the spectra of the G/Ch 50:50 film containing CO the aforementioned bands are shifted to somewhat higher wavenumbers, 1665 and 1559 cm -1 , respectively (Figure 4, spectrum (c)).…”

is the first study on supercritical impregnation of G/Ch films with clove oil (CO) • CO in films was affected by CO2 pressure, impregnation time and G:Ch ratio • CO loading was favoured at 10-20 MPa, impregnation time of 2-6 h and Gwt% 25-50% • ScCO 2 treatment had the highest plasticizing effect on G/Ch50:50 • Thermal stability of the G/Ch film with 56 mg CO/g film to 110 °C was demonstrated Abstract Supercritical CO 2 impregnation process was used for the first time to fabricate biodegradable gelatin-chitosan (G/Ch) films containing clove oil (CO) for potential use in active food packaging. All the impregnations were carried out at moderately low temperature (40 °C). Aiming to maximize CO loading in the films with acceptable morphological, structural and thermal properties, CO 2 pressure, impregnation time and G:Ch mass ratio were varied. Gelatin fraction in the films of 25-50 wt.%, scCO 2 pressures of 10-20 MPa and impregnation time of 2-6 h impregnation favoured the CO loading. Processing of the film with equal gelatin to chitosan mass ratio (G/Ch 50:50) at 10 MPa for 2 h yielded sufficiently high loading (56 mg CO/g film) without an adverse effect on morphological properties. The G/Ch 50:50 film was therefore chosen for structural and thermal analyses. ATR-FTIR analysis confirmed successful CO incorporation into the G/Ch 50:50 and its interaction with the film. Plasticizing effect of scCO 2 and CO on the film was evidenced by DSC. Incorporation of 56 mg CO/g film into the G/Ch 50:50 didn't affect thermal stability of the film. Beside environmental benefits, supercritical impregnation process enables fast fabrication of G/Ch bio-composite films containing CO, thermally stable to 110 °C, which is suitable for most of food packaging applications.

“…Incorporation of plant extracts and essential oils or their components into G/Ch blends can enhance the quality and safety of seafood products primarily for their antimicrobial activity [20,22,23]. Essential oils from aromatic plants and spices represent an attracttive natural alternative to chemical additives used in the food industry [24].…”

Supercritical CO 2 was used as a green solvent and impregnation medium for loading cellulose acetate beads with carvacrol in order to obtain a biomaterial with antibacterial properties. Supercritical solvent impregnation was performed in a high-pressure view cell at temperature of 50 ∘ C and pressures of 10, 21, and 30 MPa with the processing time ranging from 2 to 18 h. The rate of impregnation increased with the pressure increase. However, maximum impregnation yield (round 60%) was not affected by the pressure applied. Selected samples of the impregnated cellulose acetate containing 6-60% of carvacrol were proven to have considerable antibacterial effect against Gram-positive and Gram-negative bacterial strains including methicillin-resistant Staphylococcus aureus which causes severe infections in humans and animals. In addition, cellulose acetate beads containing 6.0-33.6% of carvacrol were shown to have a porous structure with submicron pores which is of interest for the controlled delivery applications.

“…The high solubility of gelatin films is associated with the presence of hydrophilic aminoacids that rehydrate in contact with water, thus increasing their solubility levels (Hoque et al, 2011;Yao, Ding, Shao, Peng, & Huang, 2017). In the present study, the comparative lower values are related to the addition of BO as well as to the low concentration of gelatin, which altogether contribute to the hydrophobicity of the optimized film, thus decreasing its dissolution.…”

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
