Description: 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, kale and yellow carrots. 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. This xanthophyll, like its sister compound zeaxanthin, has primarily been used as a natural colorant due to its orange-red color. Lutein absorbs blue light and therefore appears yellow at low concentrations and orange-red at high concentrations. Lutein is also anti angiogenic. It inhibits vascular endothelial growth factor (VEGF).oday the coloring of the egg yolk has become the primary reason for feed fortification. Lutein is not used as a colorant in other foods due to its limited stability, especially in the presence of other dyes.
Main function
1. Lutein was traditionally used in chicken feed to improve the color of broiler chicken skin. Polled consumers viewed yellow chicken skin more favorably than white chicken skin. Such lutein fortification also results in a darker yellow egg yolk.
2.Used as coloring agent in feedstuff for domestic bird, aquatic animals and pet dogs. Feed grade lutein can effectively improve the immunity of poultry and livestock. The Coloring function is particularly remarkable. It can bright feathers, hair.
3. Lutein absorption of blue, the sun's ultraviolet light, blue light into the eyes will produce a large number of free radicals, causing cataracts, so that the macular degeneration, and even cause cancer. Human eyes contain a high content of lutein, which is not made of human body, must be added to the intake of lutein. Research shows intake of lutein, help to delay the eyes of aging, degradation, disease, reduce eye disease incidence, but also can protect the retina from light damage.
4. Natural lutein is an excellent antioxidant, which can resist free radicals in human body and organ damage, which can prevent the aging of the body, such as cardiovascular disease, coronary heart disease and cancer. One of the unique function of lutein is the prevention of blindness and vision loss due to age - related macular degeneration.
