violaxanthin
Sign in to saveAlso known as all-trans-violaxanthin, trans-violaxanthin, zeaxanthin diepoxide, (3S,3'S,5R,5'R,6S,6'S)-5,6:5',6'-diepoxy-5,5',6,6'-tetrahydro-beta,beta-carotene-3,3'-diol, E 161e
Violaxanthin is a xanthophyll pigment with an orange color found in a variety of plants. Violaxanthin is the product of the epoxidation of zeaxanthin where the oxygen atoms are from reactive oxygen species (ROS). Such ROS's arise when a plant is subject to solar radiation so intense that the light cannot all be absorbed by the chlorophyll.

Violaxanthin is a xanthophyll pigment with an orange color found in a variety of plants. Violaxanthin is the product of the epoxidation of zeaxanthin where the oxygen atoms are from reactive oxygen species (ROS). Such ROS's arise when a plant is subject to solar radiation so intense that the light cannot all be absorbed by the chlorophyll.
==Food coloring== Violaxanthin is used as a food coloring under the E number E161e and INS number 161e. The coloring is not approved for use in food in the EU or the United States, but is allowed in Australia and New Zealand.
