Environment secretary Hilary Benn is encouraging research into the potential benefits and consequences of harnessing new developments in nanotechnology- engineering carried out at a microscopic level. These developments could lead to plastic packaging designed to stop food and drink spoiling by killing bacteria or preventing oxygen getting through the container.
The technology could also be used to enrich food with supplements and preserve vitamins that would otherwise be destroyed as food aged. Farmers could also use it to ensure the slow release of fertilisers at the right time for crops, and to detect threats from pests or pollutants. The technology is, however, highly controversial, with green campaigners arguing that its effects on human health are unknown.
Nanotechnology, still in its infancy, is increasingly being seen as a successor to genetically modified (GM) techniques in food production, with GM trials meeting consumer resistance and sabotage by activists.
