Nanotechnology offers interesting manufacturing and processing opportunities for the food production industry and promises a large market potential. On the other hand consumers object to the use of nanoparticles and nanomaterials in food. For this reason, the industry’s communications on this sensible subject are only very cautious, and information on current developments and applications is rare. Industry seems to be especially interested in “delivery systems” and nano-capsules for the protection of active food ingredients during manufacturing, distributation and storage. Nanoparticulate colouring agents are in use for beverages and silica nanoparticles serve as flow aid for powdered ingredients in food. Nanoscale vitamins, minerals and herbs in food supplements are on the market. Nanotechnology can also be found in food packaging, in the area of food safety and in sensor techniques.
