“…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.

“…The remarkable optical [1][2][3], magnetic [4][5][6], catalytic, and photocatalytic [7][8][9] properties of metal nanoparticles, as well as their antimicrobial, antifungal, and other types of pharmacological activities [10][11][12], have encouraged their use in many areas. Existing and potential applications of metal nanoparticles are spreading across the fields of pharmaceutical therapy [13][14][15], diagnostics [16][17][18], energy conversion [19,20], the food industry [21,22], environmental remediation [23,24], and beyond. The emerging area of nanobiotechnology has resulted in a great demand for methods that can provide rapid, high-throughput, and inexpensive synthesis and which can also be applied at the industrial level.…”

The present study reports a green chemistry approach for the rapid and easy biological synthesis of silver (Ag), gold (Au), and bimetallic Ag/Au nanoparticles using the callus extract of Lithospermum erythrorhizon as a reducing and capping agent. The biosynthesized nanoparticles were characterized with ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) analysis, and transmission electron microscopy (TEM). Our results showed the formation of crystalline metal nanostructures of both spherical and non-spherical shape. Energy dispersive X-ray (EDX) spectroscopy showed the characteristic peaks in the silver and gold regions, confirming the presence of the corresponding elements in the monometallic particles and both elements in the bimetallic particles. Fourier-transform infrared (FTIR) spectroscopy affirmed the role of polysaccharides and polyphenols of the L. erythrorhizon extract as the major reducing and capping agents for metal ions. In addition, our results showed that the polysaccharide sample and the fraction containing secondary metabolites isolated from L. erythrorhizon were both able to produce large amounts of metallic nanoparticles. The biosynthesized nanoparticles demonstrated cytotoxicity against mouse neuroblastoma and embryonic fibroblast cells, which was considerably higher for Ag nanoparticles and for bimetallic Ag/Au nanoparticles containing a higher molar ratio of silver. However, fibroblast migration was not significantly affected by any of the nanoparticles tested. The obtained results provide a new example of the safe biological production of metallic nanoparticles, but further study is required to uncover the mechanism of their toxicity so that the biomedical potency can be assessed.

“…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.
