Seeds of Change (in case I'm not the only one that didn't know) is owned by Mars Inc. the largest Candy Corporation in the world now that Birkshire's Warren Buffet has helped finance the scoop up of Wriggly's.
One of the largest privately owned Corporations, the Mars family is reclusive and worth tens of Billions. I'll have to find my purple dragon carrots elsewhere, as I won't support Mars Inc. and their appalling chocolate trade, exploitation of southern hemisphere farmers and the pushing of the nanofood front. They have pioneered nanotechnology in packaging and sensors:
"Nanotechnology will dramatically extend food shelf life. Mars Inc. already has a patent on an invisible, edible, nano wrapper which will envelope foods, preventing gas and moisture exchange. ‘Smart’ packaging (containing nano-sensors and anti-microbial activators) is being developed that will be capable of detecting food spoilage and releasing nano-anti-microbes to extend food shelf life, enabling supermarkets to keep food for even greater periods before its sale. Nano-sensors, embedded into food products as tiny chips that were invisible to the human eye, would also act as electronic barcodes. They would emit a signal that would allow food, including fresh food, to be tracked from paddock to factory to supermarket and beyond." see Nano foe
They also have patents on nano material additives for food flavour enhancement and preservation.
"Mars Inc. US Patent US5741505 nanoscale inorganic coatings: Inorganic nano-coating applied directly to a food product to provide moisture or oxygen barrier to
improve shelf life and/or flavour impact. Coating materials include permitted additives silicon dioxide (E551), magnesium oxide (MgO, E530) and titanium
dioxide (E171). Applications include hard sugar confectionery, ready-to-eat cereals, biscuits, crisps" see
Note: these metalic nanomaterials are used for sensors as well as antimicrobials and studies have shown that they are toxic.
