Lutein is a kind of oxygen of carotenoids, widespread Yu Wanshou chrysanthemum, banana, kiwi fruit and corn and other natural plant.Is a kind of excellent antioxidant, can resist oxygen free radicals in the human body cell and organ damage, preventing the body's aging caused by cardiovascular hardening, the symptom such as coronary heart disease (CHD), anticancer .Lutein is the only way to exist is the most important of the eye lens carotenoid composition, is the main point of macular pigment and antioxidant, many eye disease had a lot to do with the lack of lutein and lutein to protect eyes play an important role.
Main Function
(1)Promoting the healthy of eye and skin through reducing the risk of macular degeneration, supporting normal eye functions and protecting the retina by blocking harmful blue light.
(2)Eliminating free-radicals, protecting human body from harm, improve immunity, protecting skin from the harmful solar ray.
(3)Preventing cardiopathy and cancer.
(4)Resisting arteriosclerosis.
Application
(1)Applied in food field,mainly used as food additives for colorant and nutrient.
(2)Applied in pharmaceutical field,mainly used in vision care products to alleviate visual fatigue, reduce incidence of AMD, retinitispigmentosa (RP), cataract, retinopathy, myopia, floaters, and glaucoma.
(3)Applied in cosmetics, mainly used to whitening, anti-wrinkle and UV protection.
Brief Introduction
Lutein from Latin luteus meaning "yellow" is a xanthophyll and one of 600 known naturally occurring carotenoids. Lutein is synthesized only by plants and like other xanthophylls is found in high quantities in green leafy vegetables such as spinach and kale. In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis. See xanthophyll cycle for this topic.
Lutein is obtained by animals directly or indirectly, from plants. Lutein is apparently[citation needed] employed by animals as an antioxidant and for blue light absorption. Lutein is found in egg yolks and animal fats. In addition to coloring yolks, lutein causes the yellow color of chicken skin and fat, and is used in chicken feed for this purpose. The human retina accumulates lutein and zeaxanthin. The latter predominates at the macula lutea while lutein predominates elsewhere in the retina. There, it may serve as a photoprotectant for retina from the damaging effects of free radicals produced by blue light.
