What specific type of flavonoid provides the vibrant color to Red Oak Leaf lettuce?
Answer
Anthocyanins
The striking, vibrant color characteristic of the Red Oak Leaf variety stems from the presence of anthocyanins. Anthocyanins are classified as a specific type of flavonoid compound. This presence of color is generally correlated with a higher overall phenolic content when compared to the green version of the lettuce. Research further supported the richness of this type by showing that red oak leaf exhibited the highest overall antioxidant activity among several tested common lettuce types.
