Nanotechnology has potential applications in the food industry including increasing nutritional value, improving packaging and detecting food contaminants. Some key areas discussed are nanoencapsulation to protect nutrients, nanosensors to detect pathogens and chemicals, and active nano-enabled food packaging with antimicrobial properties. While nanotechnology offers benefits, safety research is still needed to address concerns around potential health effects of ingesting nanoparticles. Stakeholder education is important as nanotechnology in food is still an emerging field.

26. Nanoparticles Enable Speedy E. coli Detection Escherichia coli O157:H7 is one of the most dangerous agents of food-borne disease and ingesting contaminated food or water can be deadly, especially for children or the elderly. Silica nanoparticles, each housing thousands of fluorescent dye molecules, and each attached to an antibody for a given bacterium . If the bacterium sought is present the nanoparticles will quickly attach to it . Dye molecules already attached will fluoresce in this heavier sample, identifying the bacteria .
