Introduction:

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. 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 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 the retina from the damaging effects of free radicals produced by blue light. Lutein is isomeric with zeaxanthin, differing only in the placement of one double bond.

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.

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.

Lutein power is obtained marigold flower by extraction, saponification and purification. It\'s widely used in food , health care products,. etc. It\'s widely recognized in the importance of eye health, and used in food and beverage industry.


Application

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.

Lutein is also anti angiogenic.It inhibits vascular endothelial growth factor (VEGF).

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. 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

Lutein was found to be concentrated in the macula, a small area of the retina responsible for three-dimensional 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.

In nutrition

Lutein is a natural part of human diet when fruits and vegetables are consumed. According to the NHANES ********4 survey, adults in the United States average 1.7 grams per day of lutein and zeaxanthin combined. For individuals lacking sufficient lutein intake, lutein-fortified foods and dietary supplements are available. While no recommended dietary allowance currently exists for lutein, positive health effects have been seen at dietary intake levels of ***0 mg/day.The only definitive side effect of excess lutein consumption is bronzing of the skin (carotenodermia).

The functional difference between lutein (free form) and lutein esters is not entirely known. It is suggested that the bioavailability is lower for lutein esters, but much debate continues.

As a food additive, lutein has the E number E**1b (INS number **1b) and is extracted from the petals of marigold (Tagetes erecta). It is approved for use in the EU and Australia and New Zealand but is banned in the USA.


Functions

Protecting the eyes, the arteries and the lungs from damaging free radicals,
Anti oxidizationion
Support normal eye function and protect the retina by blocking harmful blue light.

Cardiovascular diseases risk reduction

Safety

In humans, the Observed Safe Level (OSL) for lutein, based on a non-government organization evaluation, is *0 mg/day.[*9] Although much higher levels have been tested without adverse effects and may also be safe, the data for intakes above the OSL are not sufficient for a confident conclusion of long-term safety.[*9] Neither the U.S. Food and Drug Administration nor the European Food Safety Authority consider lutein an essential nutrient or have acted to set a tolerable upper intake level.
