In recent years, the fast development of nanotechnology has attracted increasing attention in various fields of research. In particular, nanotechnology has emerged in the food industry as an indispensable tool for food packaging, as well as food quality sensing, due to increasing consumer demand for better food quality without compromising the nutritional aspect of the foods. Nanotechnology can serve as a tool in food manufacturing, processing, packaging, and sensing as it can have a significant impact on food quality and safety.

Nowadays, many engineered non-toxic nanomaterials with unique physical and functional properties have been developed for applications in food science. The use of nanotechnology in this sector can be found mainly in three groups: nanostructured ingredients for food processing, nano-based packaging, and food quality sensing. The former includes food processing and packaging through the inclusion of nanomaterials in the packaging structure, whereas the latter uses nanotechnology to assess food quality and safety. Nanomaterials can be applied as an additive or nutritional carrier in food packaging, or they can be employed as a biosensor or sensing element to monitor food quality. Thus far, several types of nanomaterials have been used in the food sector and have presented promising results, potentially revolutionizing the food and nutrition industry. While nanomaterial-based technology has attracted immense interest from various scientific communities and has already had an impact on the food sector, there are still a lack of studies verifying the safety limits of nanomaterials in the food industry. This is a potentially alarming aspect of the use of nanoparticles in the food industry, and to this end, the extensive health and environmental impact of nanotechnology should be explored.

The primary aim of this Special Issue is to collect up-to-date research on the use of nanomaterials in food packaging and quality sensing applications. We welcome both original research and review articles.
