lycopene to create α-carotene and β-carotene. β-carotene hydroxylase (Crtz) converts β-carotene to β-cryptoxanthin, zeaxanthin, and antheraxanthin. Ccs converts antheraxanthin into capsanthin ( Guzman et al., 2010 ). These biosynthetic enzymes are directly

free oxygen radical intermediates ( Palozza and Krinsky, 1992 ). Lycopene and β-carotene account for 90% of the total carotenoids in raw tomato fruit, with lycopene five to six times the concentration of β-carotene ( Ong and Tee, 1992 ). Consumer demand
