I have chosen nanotechnology as my topic area of choice from the food innovation module.
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
Figure 1: Image of the nanoscale, this illustration shows how small things at the nanoscale really are (nano.gov, 2013).

Nanotechnology has found many potential applications in the area of functional foods by engineering biological molecules toward functions very different from those they have in nature, opening up a whole new area of research and development.
The food industry has been using nanotechnology for a little over a decade now to change the way we grow and maintain our food. Nanotechnology uses in food has many advantages – it can give the producers the power to control how food looks, tastes and even how long it lasts. Listed below are the top ten uses of nanotechnology in foods:
1. Contamination Sensor: This flashes a light to reveal the presence of the bacteria E.coli.
2. Enhanced Nutrient Delivery: Nano-encapsulating improves the solubility of antioxidants, vitamins, healthy omega oils and other neutraceuticals

3. Green Packaging: Nano fibres can be constructed from organic corn or lobster shells and are both antimicrobial and biodegradable.

4. Antimicrobial Packaging: Edible films are produced which incorporate cinnamon, zinc, calcium, oregano oil or other materials that can kill bacteria.

5. Improved Food Storage: Nano- enhanced barriers are used to keep oxygen sensitive foods fresher.

6. Flavour: The tongue can be tricked with bitter blockers or sweet/salty enhancers.

7. Texture: Nano sized crystals and lipids improve certain foods spreadablity and stability.

8. Pesticide Reducti...

...esity is becoming an epidemic, nanotechnology could be used to create foods which are low in fat, salt and sugar but are still nutritionally dense and taste great. Food is naturally nanostructured material – simply boiling an egg causes many changes; the proteins in the egg white change shape and tangle together to form a solid. We now have the opportunity to study what exactly happens in these nanoscale changes. Nanotechnology gives us many ways to ensure our food is safe and waste is cut down. However, there are many concerns that this form of processing is another way to put more power into the hands of large food companies- yet food has never been safer than it is today largely due to the strict hygiene and sanitation practices these companies follow. As the population continues to grow – so too will the importance of new food technologies like nanotechnology.
