Nanotechnology is a field of applied sciences and technologies involving the control of matter on the atomic and molecular scale, normally below 100 nanometers. Nanomaterials may exhibit different physical and chemical properties compared with the same substances at normal scale, such as increased chemical reactivity due to greater surface area.
Nanotechnologies enable the management of food ingredients on a molecular level. Nanotechnology products could have a substantial impact on the food and feed sector in the future, potentially offering benefits for industry and the consumer, although possible risks need to be considered. Companies and institutes worldwide are currently researching and developing applications in fields such as the treatment of the mechanical and sensorial properties of food – for instance to achieve changed taste or texture – and modified nutritional value. Nanotechnology may also be used in food packaging, for instance to ensure better protection or to detect how fresh food is. The specific properties and characteristics of nanomaterials need to be considered for any potential health risks.
