Zeaxanthin is a typical oil-soluble chloroplast pigment. In nature, it is widely found in green leafy vegetables, flowers, fruits, alfalfa and yellow corn. The main pigment of yellow corn is zeaxanthin, which is about 0.1~9mg/kg in corn kernels. Green leafy vegetables are the main dietary source of lutein, but less zeaxanthin.
In the human body, zeaxanthin is mainly distributed in tissues and organs such as eyes, liver, pancreas, kidney, spleen and ovary, and plays an important role in health. In the eye, zeaxanthin is mainly concentrated in the center of the macular area of the retina.
Humans and animals cannot synthesize zeaxanthin themselves and must be obtained through food or supplements. The dietary sources of zeaxanthin mainly include yellow corn, orange sweet pepper, orange juice, honeydew melon, mango, raspberry, blueberry, peach, hazelnut, egg yolk.
