“…There were no significant changes of CS elongation due to the addition of CNFs. In this investigation, the emulsified films had higher elongation, and this was in agreement with other investigations 54 , 55 . This behavior may be attributed with a sufficient level essential oil resulting in a synergistic impact of the plasticizer and SEO.…”

A novel composite edible coating film was developed from 0.8% chitosan (CS) and 0.5% sandalwood oil (SEO). Cellulose nanofibers (CNFs) were used as a stabilizer agent of oil-in-water Pickering emulsion. We found four typical groups of CNF level-dependent emulsion stabilization, including (1) unstable emulsion in the absence of CNFs; (2) unstable emulsion (0.006–0.21% CNFs); (3) stable emulsion (0.24–0.31% CNFs); and (4) regular emulsion with the addition of surfactant. Confocal laser scanning microscopy was performed to reveal the characteristics of droplet diameter and morphology. Antifungal tests against Botrytis cinerea and Penicillium digitatum, between emulsion coating stabilized with CNFs (CS-SEOpick) and CS or CS-SEO was tested. The effective concentration of CNFs (0.24%) may improve the performance of CS coating and maintain CS-SEO antifungal activity synergistically confirmed with a series of assays (in vitro, in vivo, and membrane integrity changes). The incorporation of CNFs contributed to improve the functional properties of CS and SEO-loaded CS including light transmission at UV and visible light wavelengths and tensile strength. Atomic force microscopy and scanning electron microscopy were employed to characterize the biocompatibility of each coating film formulation. Emulsion-CNF stabilized coating may have potential applications for active coating for fresh fruit commodities.

A novel composite edible coating film was developed from 0.8% chitosan (CS) and 0.5% n sandalwood oil (SEO). Cellulose nanofibers (CNFs) were used as a stabilizer agent of oil-in-water Pickering emulsion.

“…However, according to Zheng, Yu and Pilla [ 30 ], good barrier properties against UV radiation are due to the presence of amino acid residues in proteins that have the ability to absorb UV radiation. The opacity value of the edible films obtained from bocaiuva flour ranged from 3.8 to 9.3 A/mm [ 31 ]. Films obtained on the basis of peas by Giosafatto et al [ 2 ] had an opacity value of 7.74 ± 0.26 at a wavelength of 600 nm.…”

“…However, according to Drakos et al [ 41 ], the differences resulting from the consistency of the films could be due to the different contents of protein and carbohydrates in the flours used. Additionally, Silva, Cortez-Vega, Prentice and Fonseca [ 31 ], analyzing the obtained edible films from bocaiuva flour, observed a porous structure and unevenness of the film surface, which could interfere with water vapor diffusion. Those researchers also observed the presence of lipid globules separated from the starch matrix found in the darker regions of the films.…”

Development and Characterization of Novel Composite Films Based on Soy Protein Isolate and Oilseed Flours

The possibility of using oilseed flours as a waste source for film-forming materials with a combination of soy protein isolate in preparation of edible films was evaluated. Physical, mechanical and barrier properties were determined as a function of the oilseed type: hemp, evening primrose, flax, pumpkin, sesame and sunflower. It was observed that the addition of oilseed flours increased the refraction and thus the opacity of the obtained films from 1.27 to 9.57 A mm−1. Depending on the type of flours used, the edible films took on various colors. Lightness (L*) was lowest for the evening primrose film (L* = 34.91) and highest for the soy protein film (L* = 91.84). Parameter a* was lowest for the sunflower film (a* = −5.13) and highest for the flax film (a* = 13.62). Edible films made of pumpkin seed flour had the highest value of the b* color parameter (b* = 34.40), while films made of evening primrose flour had the lowest value (b* = 1.35). All analyzed films had relatively low mechanical resistance, with tensile strength from 0.60 to 3.09 MPa. Films made of flour containing the highest amount of protein, pumpkin and sesame, had the highest water vapor permeability, 2.41 and 2.70 × 10−9 g·m−1 s−1 Pa−1, respectively. All the edible films obtained had high water swelling values from 131.10 to 362.16%, and the microstructure of the films changed after adding the flour, from homogeneous and smooth to rough. All blended soy protein isolate–oilseed flour films showed lower thermal stability which was better observed at the first and second stages of thermogravimetric analysis when degradation occurred at lower temperatures. The oilseed flours blended with soy protein isolate show the possibility of using them in the development of biodegradable films which can find practical application in the food industry.
