Nanotechnology in Food

Nanotechnology is the study and application of materials at the nano scale. A nanometer is 0.0000000001 of a meter. Over the past few years, the development of nanosciences and nanotechnology has brought news perspectives for many industry and consumer sectors.



Drying of foods is one of the most common process used for food preservation. Drying is based on the removal of water from a moist material so it decreases the water activity of the material. Therefore drying reduces microbiological activity and minimizes the risk of physical and chemical changes during its storage.
