Nanoelikagaiak: tamainak axola duenean

The use of nanotechnology has become a key tool for the development of an endless number of applications. The food sector is not an exception since the bene-fits of nanotechnology are expected to allow us to enjoy healthier, more resilient and long-lasting foods. In this work, we present the main advances related to the introduc-tion of nanotechnology in the food sector, focusing on three areas: nano-enriched foods, novel designs for food packaging and nanosensors. Finally, the controversy sur-rounding nanofood is analyzed, since although nanotechnology can contribute with lots of benefits, its use still causes fear and insecurity among the population.
