3 Outline What is Nanotechnology? Food Examples Concerns What s coming? 3

4 What is Nanotechnology? Nanotechnology ( nanotech ) is the manipulation of matter on an atomic, molecular, and supramolecular scale I want to build a billion tiny factories, models of each other, which are manufacturing simultaneously It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too big. Richard Feynman, Nobel Prize winner in physics

5 What is Nano? 5

6 Proportion of Surface Atoms 1 cm 3 1 in nm 3 80% on surface Surface properties very dominant Leads to unusual properties 6

7 Food Examples 7

8 Food Nano Now and Future Agriculture Food Packaging Supplements & Colours Food Ingredients & Processing Nano capsules for feed; vaccines; pesticides Nano ingredients for Nano sensors for Functionality; encapsulation Oxygen / temperature monitoring Nano sensors for Pathogens (animal/plant/food Nano coatings / fillers for packaging and processing equipment 8

9 Active Packaging & Intelligent Packaging Active oxygen scavenging and antimicrobials E.g. Nano silver inside polymers to reduce microbial growth Nano clay to reduce oxidation Intelligent sensors in packaging for detection of spoilage: Time/temperature Freshness indicators Tracking 9

11 Nano Delivery Products Rivalus USA Nano-partitioned protein Nano Pharmaceutical Laboratories USA Nanocules for extended energy release Source: Mintel TC Union Global Thailand Co enzyme Q 11

12 In Development Smart Milk Cartons that change colour when left out of the fridge too long Also chip in label that will trace origin 12

13 What is Nano? 1 nm 13

14 Natural Nanostructures Natural Nanostructures in Raw Foods e.g. muscle structure in meat; plant cell structures in vegetables Muscle cell Muscle fibre Muscle Fibril 500nm Muscle Fibril 14

15 Natural Nanostructures (cont) Natural Nanostructures in Current Processed Foods Thin section of low fat spread: water-in-oil emulsion Black: water White: fat 15

16 Healthy Foods by Altering the Crystallisation of Ingredients Lower salt? 16

17 Leatherhead Food Research Looking at ways to change the structure of products 17

18 Sugar Conventional fine sugar Nano spray dried sugar Amorphous spheres 18

19 Crystallisation/Self-assembly of Sugar 19

20 Control of Structure of Ingredients How will these be different in the product? Lower sugar, fat, salt Heat resistance 20

21 Consumer Concerns No benefit to consumer Food too processed Safety issues to consumer and environment Why do it? Risk of persistent nano materials such as TiO2, SiO2 21

22 Benefits & Concerns s Science and Technology Committee Report on Nanotechnologies and Foods a wide variety of nanomaterials, and whilst many types...may well prove to be harmless, others may present a higher risk. Persistent nanomaterials are of particular concern, since they do not break down in the stomach and may have the potential to leave the gut if nanomaterials are solubilised, digested or degraded, then they are of least concern Q. Chaudhry toxicologists agree that persistent nanomaterials, especially those that are non-biologically degradable, inorganic, inorganic metal oxides and metals, are particles that pose the most risk. F. Kampers 22

23 From small beginnings, nanotechnologies are fast making their presence felt. Benefiting from the opportunities presented by nanomaterials means being fully cognisant of the risks. Nanotechnology is going to be big business. Set to revolutionise business and industry most notably in medicine, food and energy production, nanotechnology is the single largest R&D investment that governments are focused on.

24 Horizon Scanning What s coming? 24

25 The World is Changing Printable circuits as thin as paper can give smart technology to everyday objects Linking physical and digital worlds 25

26 QR Codes and Other Devices e.g. QR codes for consumers to see video of product News/49614/Packaging-Innovations-lives-up-to-its-name.html 26

27 3D Printing Hershey s offers personal 3D printing of chocolate treats 27

28 To Sum Up Potential benefits for the consumer in using new technologies and nanotechnology Ways to accurately predict shelf life Coatings to reduce in-line cleaning / servicing Reduction of microbial attachment / growth Smarter safer packaging New ingredient functionality Smart filters (rancidity, allergens) Healthier foods Nanotechnology still not presently extensive in food 28
