Chemical Property:
- With metallic luster, unstable to light and hydrogen, insoluble in water, soluble in fats and fat solvents. Stored in a cool and dry place, avoid light seal.
- Lutein is a carotenoid, belonging to the photosynthetic pigment, natural widely present in vegetables (such as spinach, kale, broccoli, etc.), flower, fruit and other plants, chlorophyll A can transfer the absorbed light energy to a special state, to convert light energy, has a protective role of chlorophyll.
Usage:
Natural antioxidants lutein is an excellent, add in food can prevent cell aging and the amount of body organs of aging, but also can prevent senile macular degeneration decreased visual acuity and eye blindness, cause at the same time, also can be used as a feed additive for poultry egg coloring, as well as in the food industry as coloring and nutrition health care agent.
1.protect eyesight
Lutein is an important protective effect on macular retina, the lack of easily lead to macular degeneration and blurred vision. Then the visual degradation, myopia and other symptoms. Lutein is the precursor of NA, in the human body can be transformed into VA. The main physiological functions of lutein for eye is used as antioxidant and photoprotective role. The optic nerve is not renewable, vulnerable to the harmful free radical damage, antioxidant lutein can inhibit the formation of harmful free radicals. Lutein can absorb a large amount of blue, blue wavelengths of visible light and ultraviolet light is close to, can reach a kind of potential hazards of maximum light retinal visible light. At the retinal sensitive cell, light passes through the highest accumulation of lutein, if macular the lutein content rich will this damage reduction to a minimum.
2.antioxidant effect
Oxidation of lutein strong, can inhibit the activity of oxygen free radical activity, prevent reactive oxygen free radical damage to normal cells. The experiment proves, reactive oxygen free radicals, proteins, lipids and DNA reaction, weaken their physiological function, causing such as cancer, arteriosclerosis, aging yellow magic degeneration chronic disease. Lutein can be inactivated singlet oxygen by physical or chemical quenching, thereby protecting the body from damage, enhance the immune ability.
3.to reduce the incidence of cataract
Cataract is the main eye diseases worldwide leading to blindness, the latest research proved that lutein intake can be achieved by increasing the rate of purpose, it is suggested that the mechanism for high macular pigment density lower and the elderly lens visual density are closely related, and t
