Introduction of lutein ester:
Lutein ester is an important carotenoid fatty acid ester. At room temperature, high-purity lutein ester (content 60%-95%) is golden yellow ester orange red powder, soluble in chloroform, dichloromethane, Carbon dichloride, isochlorinated hydrocarbons, soluble in solvents such as n-hexane, acetone, ethyl acetate, ethanol, etc., more stable than lutein, but under high temperature conditions, strong acid, iron ions and oxygen Lutein esters are more damaging.
Lutein esters in nature can be divided into trans lutein esters and cis-lutein esters, which are mainly in the all-trans molecular configuration. All-trans lutein esters can be further divided into: lutein monoester and lutein diester, which are widely present in plants such as marigold flowers, pumpkin, cabbage, and first grains. Among them, the content of lutein ester in marigold flower is the most abundant, up to 30% to 40%. In general, lutein is combined with fatty acid, lauric acid and palmitic acid to form an ester.

The role of lutein ester:
1. Lutein has the function of filtering blue light and anti-oxidation, and is a key nutrient element to help eye development.
2. Lutein ester is decomposed into free lutein after being absorbed by the human body, and has the basic function of crystal lutein to supplement lutein in human body.
3. An important biological function of lutein is to protect the retina and prevent age-related macular degeneration (AMD). After natural lutein ester and zeaxanthin are taken into the human body, they are hydrolyzed by human lipase. Free form of lutein and zeaxanthin. They are deposited in the fundus macular at high concentration and can be used as an absorbent for near-ultraviolet blue light. By capturing free radicals, preventing or reducing the damage caused by oxidation and free radicals to the retina, they can effectively reduce the incidence of AMD.
4. natural lutein ester is an important carotenoid fatty acid ester, very stable to light, heat and air, lutein ester is a very stable food coloring agent. Can be widely used in food, beverage and other applications.
