The amounts of lycopene in various processed tomatoes
are shown in Fig. 4. The lycopene contents of freshSN
and fresh-ITH were 3.0 and 2.3 mg per 100 g of
tomato, respectively. With the operation of FD processing,
the lycopene contents in FD-SN and FD-ITH were
reduced to 33% and 48% of the fresh ones, respectively.
However, the amounts of lycopene of AD-SN
and AD-ITH increased 197% and 152% to that in the
fresh ones, respectively. The explanation of lycopene
drop in FD tomatoes is still unknown and needs further
investigation. However, the AD process significantly
increased the lycopene content.
