Researcher Genny Enfissi told the conference that the amounts of these substances in commercial tomato varieties was controlled by a limited gene-pool. A research programme at the college is mapping the genes of both commercial tomato varieties and wild ancestors, land races and closely-related species to identify the genes responsible for a range of characteristics, including the content of particular nutrients.
"The information can be used in conventional breeding programmes to help breeders identify parent lines and seedlings from crosses, with the qualities they are looking for," said Enfissi.
- A water-soluble tomato concentrate is the only product approved so far under the EFSA's article 13.5 procedure (see main story). The EFSA has approved the claim, by functional food and dietary supplement producer Provexis, that eating it "helps maintain normal platelet aggregation, which contributes to healthy blood flow".
