Brief Introduction

Lutein, from Latin luteus meaning "yellow", is one of over 600 known naturally occurring carotenoids. 
Found in green leafy vegetables such as spinach and kale, lutein is employed by 
organisms as an antioxidant and for blue light absorption. Lutein is present in 
the plant as fatty-acid ester, with one or two fatty acids bound to the two 
hydroxyl-groups. Saponification of lutein esters yields lutein in approximately 
a 1:2 molar ratio. Lutein is also found in egg yolks, animal fats and the corpus 
luteum. 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.
The principal natural stereoisomer of lutein is (3R, 3′R, 6′R)-beta, epsilon-carotene-3, 3′-diol.
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. 
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.
The Marigold Extract (Lutein: E number E161b) used as a food additive, is derived from the flower 
petals of the plant Tagetes erecta.

Application and usage

1) As a pigment: Orange natural pigment is widely used in chicken feed and also in some food,  but the scope is limited because they do not dissolve in water.

(2) eye protection: Lutein can absorb  blue light.  The sun's ultraviolet, blue light into eyes will produce a large number of free radicals, cause cataracts, macular degeneration and even cancer. The human's eye contains high level of lutein which can not be produced by human' bodies and which must be supplemented by intake of it. Studies show that intake of lutein will help slow the aging, degradation, disease occur of eyes and reduce the incidence of eye-diseases and protect the retina from light damage.

(3) antioxidant: The latest studies show that lutein is helpful for  the treatment of heart disease and may prevent arterial wall thickening.

Application

Lutein has the characteristics, such as natural, nutrition and multifunction. It is extensively used in food, health products, cosmetics, pharmaceutical and feed additive.
(1)Applied in food field, it is mainly used as food additives for colorant and nutrient.
(2)Applied in pharmaceutical field, it is mainly used in vision care products to alleviate visual fatigue, reduce incidence of AMD, retinitispigmentosa (RP), cataract, retinopathy, myopia, floaters, and glaucoma.
(3)Applied in cosmetics, it is mainly used to whitening, anti-wrinkle and UV protection.
(4)Applied in feed additive, it is mainly used in feed additive for laying hens and table poultry to improve the color of egg yolk and chicken. Make high commercial value fishes more attactive, such as salmon, trout and spectacular fish.
