1. Introduction of lutein esters

Lutein is a naturally occurring carotenoid that is widely found in natural plants such as marigold, pumpkin and cabbage. Marigold is particularly rich in lutein, which is present as an ester of lutein with fatty acids. Lutein is used as a yellow pigment in various ingredients, such as functional foods and nutraceuticals, with well-known pharmacological effects and applications. Natural lutein esters are effective in reducing the incidence of age-related macular degeneration. Lutein ester powder is a free-flowing powder using microencapsulation technology and is widely used for food nutritional fortification, especially for dried food products with water.

3.Benefits and function of lutein esters

lutein esters

An important biological function of lutein is to protect the retina from UV damage. Age-related macular degeneration (ADM) is currently found globally to be a major blinding eye disease in people over the age of 65.

Natural lutein esters and zeaxanthin esters are ingested into the human body and hydrolyzed into free forms of lutein and zeaxanthin by the action of human lipase. They are deposited in high concentrations in the macula of human eyes, and can act as absorbers of near-ultraviolet blue light, driving protective effects by trapping free radicals, preventing or reducing oxidation and damage brought by free radicals to the retina, which can effectively reduce the incidence of ADM.

3.3. Enhancement of immune effect

Recent studies have found that luteolin supplementation to the body promotes antigen-stimulated lymphocyte proliferative responses and can affect the functional expression of cell surface molecules at the overall animal level. The modulatory effect of luteolin on cellular immunity is mainly shown in relation to apoptosis and gene regulation.

3.4. Skin care and cardioprotective effects

Luteolin ester as a strong antioxidant can inhibit the activity of reactive oxygen radicals and can prevent the damage of normal skin cells by reactive oxygen radicals. Therefore, lutein esters can be made into a variety of skin care products and cosmetics, used to protect the health of the skin and prevent skin damage. It has been suggested that people who regularly consume carotenoids have a reduced risk of cardiovascular disease, and in 1994, Morrs et al. found that total carotenoid levels in the blood were inversely related to the risk of coronary heart disease
