Similarly, Dewanto
et al. (2002) found that thermal processing increased the total
antioxidant activity of tomato from 4.13 ± 0.36 to 6.70 ± 0.25 lmol
of vitamin C equivalents/g of tomato after 30 min of heating at
88 C. The total antioxidant activity increased because larger
amounts of lycopene were released from the matrix during thermal
processing.
