What is lycopene?
Tomatoes are known for their high lycopene content. Lycopene belongs to the carotinoid compounds and it gives tomatoes their chracteric red coloration. Lycopene is considered to be a radical scavenger. The availability of lycopene is greater in processed and heated tomato products such as tomato paste than in fresh tomatoes, because heating breaks open cell structures. This results in the release of lycopene.
