Anthocyanin

Anthocyanin-rich tomatoes are also called ‘blue’ tomatoes, based on their blue (unripe) skin colour. Anthocyanins are powerful flavonoids that help regulate cellular activity and have numerous biochemical and antioxidant effects. Our bodies benefit when we eat plants with anthocyanins. Fruit size is important when considering Anthocyanin levels, because smaller tomatoes will have higher Anthocyanin levels than larger tomatoes. This is because most Anthocyanin is found in the tomato skin (rather than the flesh) and sunlight hitting the skin is what regulates Anthocyanin production.
