Several studies
show that difference exists in total antioxidant activity in pepper,
may be attributed to the different causes, like fertilization, fruit
ripening and temperature (Núñez, González, GrimaldoJuárez, &
Díaz, 2011). The total antioxidant activity differences observed
between the genotypes could possibly be due to the diversity
and complexity of antioxidants compounds present in them
respectively. It has been reported that phenolic compounds, ascorbic acid and carotenoids can contribute to antioxidant activity.
