Which pigment, besides beta-carotene, contributes to the overall antioxidant activity in yellow tomatoes?
Answer
Lutein
While beta-carotene is significant for Vitamin A conversion, the text notes that the overall antioxidant activity in yellow tomatoes is also bolstered by the presence of other carotenoids. Specifically mentioned is lutein, which contributes to the tomato's protective compounds. This highlights that even though yellow tomatoes lack high concentrations of lycopene (the primary pigment in red tomatoes), they possess a different, diverse blend of carotenoids, including lutein, that contributes positively to antioxidant defense.
