The orange color tomatoes are better for you and taste better . However people buy by sight and prefer the red color . I hope this is a help.

If you are interested in lycopene content and beta-carotene, please investigage Momordica Cochinchinensis. Nothing comes close, including tomatoes.

"Tangerine" is produced by gene t, cultivars carrying gene t, include Golden Jubilee, Orange Early, Golden Delight, Sunray, Glecker Gold Glow, Golden Glow as well as a Burpee variety called simply, Tangerine.

However I am confused by all this business about cis lycopene isomer, I was always under the impression that gene t caused a lack of lycopene and a profusion of zeta-carotene.

Apparently the gene t (tangerine mutation) causes the accumulation of prolycopene which is 7Z,9Z,7'Z,9'Z-tetra-cis-lycopene instead of the normal all-trans-lycopene.

The gene codes for an enzyme that isomerises carotenoids - carotenoid isomerase - CRTISO.
