Active packaging based on wheat germ protein isolate–Malva sylvestris leaf mucilage embedded with D-limonene nanoliposome: preparation and characterization
Background
The aim of this study is to prepare wheat germ protein/Malva sylvestris leaf mucilage (WGPI/MSLM) biocomposite layers embedded with D-limonene nanoliposomes (NLP). The effects of WGPI/MSLM ratio (0.4–2.5), NLP (0–3%), and glycerol content (35–50%, w/w based on WGPI weight) on water vapor permeability (WVP), thickness, antioxidant activity, mechanical properties, and solubility of the fabricated bio-nanocomposites were investigated through faced-centered central composite design.
Results
Our results showed the effects of WGPI/MSLM ratio, glycerol content, and liposome content as well as the interaction between the ratio and NLP content on WVP was significant. The sample with 3% NLP and 35% glycerol and a ratio of 0.4 WGPI/MSLM had the lowest solubility. As the ratio of WGPI/MSLM increased, the value of tensile strength (TS) of the samples increased. The lowest elongation at break (26.21%) exhibited by film with 2.5 WGPI/MSLM, 35% glycerol, and no NLP. The highest antioxidant activity (58.6%) was observed in formulated films with 3% NLP, and a WGPI/MSLM ratio of 0.4. The optimal active film was obtained at a ratio of 0.4 WGPI/MSLM, 35% glycerol, and 3% NLP. The analysis confirmed the antibacterial activity of the optimal films against Escherichia coli and Staphylococcus aureus, as well as the larger contact angle of the optimal film compared to the control film and the greater roughness of the optimal film compared to the control sample.
Conclusions
In conclusion, this study successfully produced active films of wheat germ protein/Malva sylvestris leaf mucilage embedded with D-Limonene nanoliposomes. The optimal active film exhibited low solubility, high tensile strength, high antioxidant activity, and antibacterial activity against Escherichia coli and Staphylococcus aureus.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
