Zeaxanthin is a new oil soluble natural pigment widely found in green leafy vegetables, flowers, fruits, goji berries and yellow corn. In nature, it often coexists with lutein, beta-carotene, cryptoxanthin, etc., and forms carotenoid mixture.



Pure zeaxanthin is a crystalline powder, orange - red, odorless. Its dilute solution was orange red and above 10℃ was blood red oily liquid, and below 10℃ was yellow semi-solidified oily liquid.


It has good oxygen resistance, stable to other ions, acids, alkali and reducing agent Na2SO3. Low temperature is stable, high temperature short-term treatment is basically stable, long time is not stable; The stability of Fe and Al is poor. The stability of zeaxanthin was significantly affected by light in the visible and ultraviolet regions. Zeaxanthin in solid food is stable under normal temperature and natural light condition, 1% solution is sensitive to sunlight.


In 21st, the UN FAO/WHO and the UN expert committee on food additives in 1977 stipulated that any pigment isolated from a known food with no change in chemical structure and with the use of a concentration consistent with the natural concentration in the original food can be regarded as a food without the need for toxicological data. Zeaxanthin is one of the ingredients in known food corn and belongs to carotenoid. Considering the physicochemical analysis results, it can be considered safe and non-toxic and can be directly applied in food, medicine and cosmetic industry with the maximum usage of 5.0g /kg.


Zeaxanthin is a typical oil soluble chloroplast pigment.In nature, vast

It is found in green leafy vegetables, flowers, fruits, goji berries and yellow corn.The main pigment of yellow corn is zeaxanthin.


In human body, zeaxanthin is mainly distributed in eye, liver, pancreas, kidney, spleen, ovary and other tissues and organs, and plays an important role in health.In the eyes, zeaxanthin is concentrated in the center of the macular area of the retina. Zeaxanthin cannot be synthesized by itself and must be obtained through food or supplements.Dietary sources of zeaxanthin mainly include yellow corn, orange sweet pepper, orange juice, cantaloupe, mango, raspberry, blueberry, peach, wolfberry, egg yolk, etc.
