Nanoelikagaiak : tamainak axola duenean Nanofoods : when size does matter

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 benefits 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 introduction of nanotechnology in the food sector, focusing on three areas: nano-enriched foods, novel designs for food packaging and nanosensors. Finally, the controversy surrounding nanofood is analyzed, since although nanotechnology can contribute with lots of benefits, its use still causes fear and insecurity among the population. KEYwORDS: nanotechnology, food science, food packaging, nanosensor.
