With the increasing demand for safe, high-quality, and sustainable food, nanomembranes
have attracted significant interest as innovative solutions in food processing. They
are extremely thin structures created from special materials that allow for the selective
filtration of very small particles. In the food industry, such approaches are increasingly
used for packaging and processing, as they can slow down food degradation and thus
extend its shelf life. This article examines the potential of utilizing nanomembranes
as ecological tools at various stages of the food chain, ranging from advanced filtration
of food liquids to the development of smart and active packaging. This study reviews
the recent research in the field, highlighting the applications developed and presenting
targeted advantages and disadvantages. The developed applications primarily focus
on extending the shelf life of products while also discussing their antioxidant and
antibacterial attributes. By highlighting the latest applications and emerging research
directions, this article underscores the pivotal role of nanomembranes in facilitating
the transition to a modern, sustainable, and environmentally responsible food industry.
However, current research faces several challenges. Most products are less biodegradable
and, consequently, could harm the environment. Additionally, data on the long-term
effects of these materials on human health, particularly when used in packaging that
comes into direct contact with food, remain insufficient. Therefore, more sustainable
solutions are needed, such as nanomembranes based on natural biopolymers. Further
studies are required to assess their safety and real-world effectiveness under industrial
conditions.
