Neoxanthin, violaxanthin, lutein, β-cryptoxanthin, α-carotene and β-carotene are the major carotenoids for Ponkan mandarin. During the harvesting period, the contents of violaxanthin, β-cryptoxanthin and β-carotene increase significantly. For Liucheng orange, neoxanthin, violaxanthin, lutein, antheraxanthin, β-cryptoxanthin, α-carotene and β-carotene are the major carotenoids. Among them, neoxanthin, violaxanthin, lutein, antheraxanthin and β-cryptoxanthin increase significantly during the harvesting period. The β-cryptoxanthin and β-carotene are the major contributors to the color of Ponkan mandarin juice while neoxanthin, violaxanthin, lutein and antheraxanthin are the major ones for the color of Liucheng orange juice.Read More
