God gives us a gift to protect our vision-Natural Lutein

Abstract: Lutein as natural colors, which are found in many colorful fruits and vegetables. A great deal of epidemiological evidence shows, Lutein plays an important role in preventing

some cancers and chronic diseases in human, It’s a hot topic of international for the researching area of functional food. In this paper for the structure, properties and function of Lutein’s has

details introducing and for the future application of it in food is prospected.

Keywords: Lutein, Properties, Antioxidant, Physiological function.

Carotenoids are a series of mixtures found in fruits, vegetables, and green plants. It gives humans a bright and pleasant color such as brilliant yellow, orange and red for a dietary fruit, vegetable. In green plants with leaves, these bright colors are obscured by chlorophyll, but when autumn comes, Chlorophyll oxidation discoloration.

Carotenoids show their beautiful colors in autumn leaves.

At present, there are more than 600 kinds of carotenoids in nature, of which only about 20 are found in human blood and tissue. Carotenoids found in the human body mainly include

α-carotene, β-carotene, Cryptoxanthin, Lutein, lycopene, and zeaxanthin. Some of these carotenoids are precursors of VA, as it can be converted to VA in a human body, so it’s been getting people's attention for a long time. With the research of the carotenoid, the functions of lutein, zeaxanthin, cryptoxanthin, and lycopene are gradually discovered and recognized. Lutein was first extracted from Carrot root by Heinrich Wilhelm Ferdinand Wackenroder in 1831. After that, Berzdlius also extracted Lutein from the autumn’s yellow leaf in 1837. Then, Other researchers extracted Lutein from seaweed and yolk. The latest research shows that Lutein can protect vision, it also has to prevent cataracts and arteriosclerosis, enhancing immunity, especially preventing carcinogenesis, delaying cancer and so on, which has become the focus of scientific research at present.

Our company produces 5 %, 10%, 20%, of Lutein has been sold to 40 countries in the world, for nearly 2 million end-consumers to provide health products, it is a great honor.
