Lutein – Small Plastic Injection Molding Machine Manufacturer – Small-sized Plastic Molding Machine

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 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
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 protect from oxidative stress and high-energy light. Various research studies have shown that a direct relationship exists between lutein intake and pigmentation in the eye. Several studies also show that an increase in macula pigmentation decreases the risk for eye diseases such as Age-related Macular Degeneration (AMD). The only randomized clinical trial to demonstrate a benefit for lutein in Macular Degeneration was a small study, in which the authors concluded that visual function is improved with lutein alone or lutein together with other nutrients and also that more study was needed .
Lutein may also play a role in Haidinger’s brush, an entoptic phenomenon that allows humans to detect polarized light.
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).
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 E161b and is extracted from the petals of marigold (Tagetes erecta).
Several researchers including a group led by John Paul SanGiovanni of the National Eye Institute, Maryland found that high intakes of Lutein and zeaxanthin (nutrients in eggs, spinach and other green vegetables) are associated with a lower risk of blindness (macular degeneration), affecting 1.2 million Americans, mostly after age 65. (journal Archives of Ophthalmology).
Whether this relation is causal and whether lutein and zeaxanthin actually reduce the risk of AMD is being studied.
Some foods are considered good sources of the nutrients:
Lutein/zeaxeathanin (micrograms per hundred grams)
garden peas
Brussels sprouts
Pistachio nuts
turnip greens
romaine lettuce
collard greens
Relationship with diseases of the eye
There is epidemiological evidence of a relationship between low plasma concentrations of lutein and zeaxanthin on the one hand, and the risk of developing age-related macular degeneration (AMD) on the other. 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.
In 2007, in a 6-year study, John Paul SanGiovanni of the National Eye Institute, Maryland found that lutein and zeaxanthin (nutrients in eggs, spinach and other green vegetables) protect against blindness (macular degeneration), affecting 1.2 million Americans, mostly after age 65. Lutein and zeaxanthin reduce the risk of AMD.
Commercial value
The lutein market is segmented into pharmaceutical, nutraceutical, food, pet foods, and animal and fish feed. The pharmaceutical market is estimated to be about US $ 190 million, nutraceutical and Food is estimated to be about US $ 110 million. Pet foods and other applications are estimated at US $ 175 million annually. Apart from the customary age related macular degeneration applications, newer applications are emerging in cosmetics, skins and as an antioxidant. It is one of the fastest growing areas of the US $ 2 billion carotenoid market.
