Eye's Angel-Lutein

The Introduction of Lutein
Lutein is a xanthophylls 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 a lipophilic molecule and is generally insoluble in water. Lutein is present in plants as fatty-acid esters, with one or two fatty acids bound to the two hydroxyl-groups.
The Source of Lutein
Many fruits and vegetables contain lutein, but due to the low content, it cannot be easily separated. The occurrence of marigold flowers makes it to be an easily thing. Marigold flower is an annual herb with orange color. Lutein is the activity ingredient of marigold flower extract, lutein is firstly been found in marigold flower petals from Switzerland. It exists as an 'esterified' form and is commonly known as lutein ester. Lutein ester is derived from marigold flowers, which is a rich, safe and natural source of lutein.
The Function of Lutein
1.As a pigment, lutein 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.
2.Role in human eyes, Lutein was found to be concentrated in the macula, a small area of the retina responsible for central vision. The hypothesis for the natural concentration is that lutein helps keep the eyes safe from oxidative stress and the high-energy photons of blue light.
3.Cataracts, there is also epidemiological evidence that increasing lutein and zeaxanthin intake lowers the risk of cataract development. Consumption of more than 2.4 mg of lutein/zeaxanthin daily from foods and supplements was significantly correlated with reduced incidence of nuclear lens opacities.

The lutein market is segmented into pharmaceutical, nutraceutical, food, pet foods, and animal and fish feed. Lutein become more and more popular this days, and it’s a potential product in the future
