Overview: Nanoscience has its roots in quantum physics(qp) and it is all about size and self assembly.However while change qp deals with subatomic particles and waves nano relates to the atomic and molecular level.expect the unexpected at the nano-level as atomic behavior and properties as normally encountered is dramaticaly changed at this particular properties such as color change due to refraction of light.Gold is a good example as the myriad of colourful paintings of gs on cathedral windows are composed of nanogold.There are two types of nanofabrication called top down which is mainly our concern in foods and bottom up which deals with self assembly of nanoparticles into wires and nanorods with hundreds of times the strength of steel a stairway to the stars has been proposed as has space elevators. A nanoparticle is 1to 100 billionth of a meter and are not visible to the naked eye unless agglomerated such as in the above nanogold paintings.they can be observed using a laboratory microscope.

Nanoparticles are used in every aspect of food and food processing.Their use promises enhanced food products and methods of manufacture together with improvised quality via more better preservation.However there are some downsides which if left unregulated could and will present consumer health issues.This is the crux of our discussion. contaminants can be extracted from the nanoclays used to form enhanced barrier protection particularly in beverages like beer.the extractables from container to liquid (beer) must be carefully monitored as alcohol in beer together with small particle size spell high extractables.zinc oxide is used to protect from uv rays however nano zno has been found to cause lung health issues.more examples are given in the discussion. the gains far outweigh the risks providing proper controls are put in place.

The fda currently does not monitor the area but a task force is currently looking into guidelines which should beforth coming. a brave new food world awaits as interactive food ingredients currently being developed would allow consumers to choose the color and desired flavor.Ingested nanocapsules using nanosensors would inject the body with needed nutrients of the latter including vitamins to treat deficiencies.

Why should you Attend: Nanotechnology is having a significant impact on food.government regulations have not kept pace with safety guidelines and regulations.Packaging in particular uses nano materials to reinforce the plastics and resins in order to provide safer barriers to environmental debris particularly gases such as carbon monoxide.the particles are small 1-100 nanometers and are more easily able to contaminate the food contents.

Nanotechnology and its chemistry will impact every facet of the food industry.this includes storage bins wrappers and most important of all food additives for taste and ingestion.I made from nanogoldn order to understand this impact a knowledge of nanoscience is required.
