To evaluate lycopene content the absorption coefficient of
3150 dL g1 cm1 in hexane at 502 nm was used. The measurements
performed at 471 nm were used to calculate the content of the rest of carotenes as b-carotene equivalents (BCeq), finally giving total carotenes content (specific absorption coefficient of
3450 dL g1 cm1 for lycopene at 472 nm, and of 2049 dL g1 cm1
for b-carotene at 475 nm, Goo
