Detail Information of Marigold Extract

Marigold Extract  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.

Marigold Extract Lutein is obtained by animals directly or indirectly, from plants.
Lutein is apparently 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 to protect the retina from the ionizing effect of blue light.
The principal natural stereoisomer of lutein is (3R,3′R,6′R)-beta,epsilon-carotene-3,3′-diol.
Lutein is a lipophilic molecule and is generally insoluble in water.
The presence of the long chromophore of conjugated double bonds (polyene chain) provides the distinctive light-absorbing properties.
The polyene chain is susceptible to oxidative degradation by light or heat and is chemically unstable in acids.
Marigold Extract  Lutein is present in plants as fatty-acid esters, with one or two fatty acids bound to the two hydroxyl-groups. For this reason, saponification (de-esterfication) of lutein esters to yield free lutein may yield lutein in any ratio from 1:1 to 1:2 molar ratio with the saponifying fatty acid.
As a pigment
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.
Marigold Extract Lutein was traditionally used in chicken feed to provide the yellow 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.
Today 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.
Role in human eyes
Marigold Extract 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.
Various research studies have shown that a direct relationship exists between lutein intake and pigmentation in the eye.
Lutein may play a role in Haidinger's brush, an entoptic phenomenon that allows humans to detect polarized light.
There is epidemiological evidence of a relationship between low plasma concentrations of lutein and zeaxanthin, and an increased risk of developing age-related macular degeneration (AMD).
Some studies support the view that supplemental lutein and/or zeaxanthin help protect against AMD.
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, as revealed from data collected during a 13- to 15-year period in the Nutrition and Vision Project (NVP).
Photophobia (abnormal human optical light sensitivity)
In nutrition
Lutein is a natural part of human diet when fruits and vegetables are consumed.
For individuals lacking sufficient lutein intake, lutein-fortified foods are available, or in the case of elderly people with a poorly absorbing digestive system, a sublingual spray is available.
As early as 1996, lutein has been incorporated into dietary supplements.
While no recommended daily allowance currently exists for lutein as for other nutrients, positive effects have been seen at dietary intake levels of 6–10 mg/day.
The only definitive side effect of excess lutein consumption is bronzing of the skin (carotenodermia).
As a food additive, lutein has the E number E161b (INS number 161b) and is extracted from the petals of marigold (Tagetes erecta).
It is approved for use in the EU and Australia and New Zealand however is banned in the USA.
