Special Issue Information

Dear colleagues,

Recent developments in nanoscience and nanotechnology are impacting the food industry more and more. In particular, research on innovative food packaging materials is receiving great attention as a powerful tool to extend the shelf life of food products, preserve their characteristics, improve food safety, and reduce food waste due to spoilage. Active packaging and intelligent packaging are new concepts, born from a deeper understanding of the interactions between food and its environment: packaging is endowed with properties not only able to preserve food quality, but also to monitor its status and warn about problems.

This Special Issue is devoted to the development of bio-based nanocomposites to be used in food packaging applications. The term “bionanocomposite” refers to nanocomposites including a naturally occurring polymer (biopolymer) mixed with inorganic solids and exhibiting at least one dimension on the nanometer scale. Such hybrid materials are designed to be invaluable for their environmental sustainability and for the multifunctional properties they can exhibit, such as biodegradability, antimicrobial activity, mechanical and thermal characteristics, and high barrier properties against the diffusion of oxygen, carbon dioxide, flavor compounds, and water vapor. For this Special Issue, we invite contributions on innovative preparation and processing technologies to obtain bio-based polymer nanocomposites with enhanced food packaging performance, as well as different characterization approaches and application cases.

Full-size articles, short communications, and reviews are welcome.

Replacing the petroleum-based materials in the food industry is one of the main objectives of the scientists and decision makers worldwide. Biodegradable packaging will help diminish the environmental impact of human activity. Improving such biodegradable packaging materials by adding antimicrobial activity will not only extend the shelf life of foodstuff, but will also eliminate some health hazards associated with food borne diseases, and by diminishing the food spoilage will decrease the food waste. The objective of this research was to obtain innovative antibacterial films based on a biodegradable polymer, namely alginate. Films were characterized by environmental scanning electron microscopy (ESEM), Fourier-transform infrared spectroscopy (FTIR) and microscopy, complex thermal analysis (TG-DSC-FTIR), UV-Vis and fluorescence spectroscopy. Water vapor permeability and swelling behavior were also determined. As antimicrobial agents, we used silver spherical nanoparticles (Ag NPs) and lemongrass essential oil (LGO), which were found to act in a synergic way. The obtained films exhibited strong antibacterial activity against tested strains, two Gram-positive (Bacillus cereus and Staphylococcus aureus) and two Gram-negative (Escherichia coli and Salmonella Typhi). Best results were obtained against Bacillus cereus. The tests indicate that the antimicrobial films can be used as packaging, preserving the color, surface texture, and softness of cheese for 14 days. At the same time, the color of the films changed (darkened) as a function of temperature and light presence, a feature that can be used to monitor the storage conditions for sensitive food.

Interest in the development of smart and active biodegradable packaging materials is increasing as food manufacturers try to improve the sustainability and environmental impact of their products, while still maintaining their quality and safety. Active packaging materials contain components that enhance their functionality, such as antimicrobials, antioxidants, light blockers, or oxygen barriers. Smart packaging materials contain sensing components that provide an indication of changes in food attributes, such as alterations in their quality, maturity, or safety. For instance, a smart sensor may give a measurable color change in response to a deterioration in food quality. This article reviews recent advances in the development of active and smart biodegradable packaging materials in the food industry. Moreover, studies on the application of these packaging materials to monitor the freshness and safety of food products are reviewed, including dairy, meat, fish, fruit and vegetable products. Finally, the potential challenges associated with the application of these eco-friendly packaging materials in the food industry are discussed, as well as potential future directions. Full article
