The scientists involved in the European funded Profood project are trying to identify key genes responsible for flavonoid production in order to develop varieties high in these compounds.
Flavonoids have been shown to possess crucial benefits to health, protecting against cardiovascular diseases and some forms of cancer. The scientists say that genetically modified crops with a greater content of antioxidants, such as natural flavonoids or other phenolic compounds, could be considered a 'second generation functional food'.
Other such foods include eggs improved by adding fish oils to chicken feed and rice with a higher content of vitamins and iron.
The researchers intend to use knowledge gained in their current work for modification of other crops, in particular cereals.
