Kantaksantin ili E161g je karotenoidni pigment vrlo raširen u prirodi. Karotenoidi spadaju u veliku klasu fitohemikalija poznatih kao terpenoidi. Hemijska formula kantaksantina je C40H52O2. Prvi put je izoliran iz jestivih gljiva. Kasnije je pronađen u zelenim algama, bakterijama, rakovima i nekim vrstama riba poput šarana.
