“…Since biopolymer‐based films usually have poor barrier and mechanical properties, to overcome these problems, either these polymers are used in combination, or plasticizers, fillers, and/or cross‐linking agents are used in biocomposite films. The use of nanoparticles in packaging films is one of the best ways to improve physicochemical and functional characteristics such as antioxidant and antimicrobial activity (Ahmadi et al., 2019; Jafarzadeh et al., 2021). Metal and metal dioxide nanoparticles are most widely used in packaging films due to their optical characteristics, good flexibility, impermeability to gases, and antimicrobial activity (Jafarian et al., 2020).…”

The purpose of this study was to evaluate the effects of a combination of zinc oxide (ZnO‐N) nanoparticles and fennel essential oil (FEO) on the functional and antimicrobial properties of potato starch films. Films based on potato starch containing a combination of ZnO‐N (1, 3, and 5%(w/w)) and FEO (1, 2, and 3% (w/w)) produced by casting method and water solubility, water absorption capacity (WAC), barrier properties, mechanical properties, color indexes, and antimicrobial activity of the films against Staphylococcus aureus, Escherichia coli, and Aspergillus flavus were studied. The combination of ZnO‐N and FEO had a significant decreasing effect on solubility, WAC, water vapor and oxygen permeability, elongation, and L* index. These additives had an increasing impact on tensile strength, Yang's modulus, and a* and b* indexes (p < .05). By increasing the concentration of ZnO‐N and FEO, the antimicrobial activities of bionanocomposite films significantly increased (p < .05). Both ZnO‐N and FEO had a significant effect in this respect, although the effects of ZnO‐N were more significant. In conclusion, an excellent synergistic effect of ZnO‐N and FEO was observed in potato starch films.

“…Biodegradable edible coatings have been widely studied recently as they represent a sustainable and environmentally sound solution for primary packaging in the food industry. They can act as a barrier against microbial contamination, decrease the rate of oxidation, prevent or decrease the rate of moisture loss and other types of physical deterioration [ 1 , 2 , 3 ]. Barrier properties of edible coatings in the sense of physical coating integrity and cracks occurrence are often studied by means of scanning electron microscopy [ 4 , 5 , 6 ].…”

Plant Byproducts as Part of Edible Coatings: A Case Study with Parsley, Grape and Blueberry Pomace

et al. 2021

Studies dealing with the development of edible/biodegradable packaging have been gaining popularity since these commodities are marked as being ecofriendly, especially when byproducts are incorporated. Consequently, this study aimed at the development of chitosan-based coatings with plant byproducts. Their sensory properties, colour attributes, occurrence of cracks in microstructure and biodegradability were analysed. Coatings containing grape and blueberry pomace had statistically significantly (p < 0.05) higher levels of colour intensity. Coating samples were characterised by lower aroma intensity (3.46–4.77), relatively smooth surface (2.40–5.86), and low stickiness (2.11–3.14). In the overall hedonic evaluation, the samples containing parsley pomace in all concentrations and a sample containing 5% grape pomace achieved a statistically significantly (p < 0.05) better evaluation (5.76–5.93). The lowest values of the parameter ΔE2000 were recorded for the sample containing 5% parsley pomace (3.5); the highest was for the sample with 20% blueberry pomace (39.3). An analysis of the coating surface microstructure showed the presence of surface cracks at an 80 K magnification but the protective function of the edible coating was not disrupted by the added plant pomace. The produced samples can be considered to have a high biodegradability rate. The results of our experimentally produced coatings indicate their possible application on a commercial scale.

“…Nanoparticles are engineered to sustain high electron mobility in order to achieve fast field responses with extraordinary dielectric constants and minimal losses in high-frequency applications [ 129 ]. The engineered bio-nanocomposite dielectrics have higher dielectric constants at elevated frequencies and can process polymers at low temperatures as compared to other conventional materials ( Figure 7 ) [ 130 ]. Chitosan is preferred in current research prospects due to its ease of accessibility, low cost, environmental friendliness and outstanding mechanical characteristics [ 131 ].…”

Herein, we report recent developments in order to explore chitin and chitosan derivatives for energy-related applications. This review summarizes an introduction to common polysaccharides such as cellulose, chitin or chitosan, and their connection with carbon nanomaterials (CNMs), such as bio-nanocomposites. Furthermore, we present their structural analysis followed by the fabrication of graphene-based nanocomposites. In addition, we demonstrate the role of these chitin- and chitosan-derived nanocomposites for energetic applications, including biosensors, batteries, fuel cells, supercapacitors and solar cell systems. Finally, current limitations and future application perspectives are entailed as well. This study establishes the impact of chitin- and chitosan-generated nanomaterials for potential, unexplored industrial applications.
