Natural lutein ester, an essential carotenoid fatty acid ester, is predominantly sourced from marigold chrysanthemum and extracted as Marigold Extract. This key compound is not only a nutrient powerhouse but also a vital ingredient in various applications such as Natural Food Colorants, Cosmetics Materials, dietary supplements for the aged, and Dietary Supplements overall. With concentrations reaching up to 30% to 40% in marigold plants, it serves as a premier industrial source of lutein esters.
In marigold and similar botanicals, lutein combines with fatty acids (such as lauric acid and palmitic acid) forming esters, notably including the most abundant ester variant – lutein palmitate diester.
The ester form exhibits a luxurious golden hue due to its all-trans configuration with C=C long chain conjugated color groups. Uniquely stable because of the absence of reactive groups on both ends, lutein ester stands out as a very stable natural food colorant. It maintains resilience against light, heat, and air exposure, thereby allowing its widespread use in foods, beverages, cosmetics, and other products. Emulsified, it can transform into water-soluble colorants, offering an alternative to chemically synthesized food grade dyes, thereby enhancing consumer health in the process.
Lutein ester plays a critical role in eye health, particularly for seniors. It has been identified that these natural compounds can prevent Age-related Macular Degeneration (AMD), a leading cause of blindness among individuals over 65 years old. Upon hydrolysis by human lipase, natural lutein ester and zeaxanthin ester release free lutein and zeaxanthin, which accumulate in high amounts at the macula of the human retina. Acting as potent absorbers of near ultraviolet blue light, they effectively reduce the risk of AMD by neutralizing free radicals and preventing or mitigating oxidative damage, thus serving as indispensable nutrient supplements for the aged.
Recent studies have found that at the level of animals as a whole, the supplementation of lutein in vivo can promote the antigen-stimulated lymphocyte proliferation response and can affect the functional expression of cell surface molecules. The regulatory effect of lutein on cellular immunity is mainly manifested in the relationship with apoptosis and gene regulation.
Lutein ester, as a strong antioxidant, can inhibit the activity of reactive oxygen species and prevent the damage of reactive oxygen species to normal skin cells. Therefore, lutein esters can be made into a variety of skin care products and cosmetics to protect the health of the skin and prevent skin damage. Cardiovascular disease is one of the leading causes of death, and the causes are very complex. Studies have shown that people who regularly consume carotenoids have a reduced risk of cardiovascular disease. In 1994, Morris et al. found that the level of total carotenoids in the blood was inversely proportional to the risk of coronary heart disease. In the same year, Street et al. showed that both lutein and zeaxanthin could significantly reduce the incidence of myocardial infarction. In 1997 and 1999, Inbarren and Stephen et al studied the effects of blood levels of A-carotene, B-carotene, lutein, zeaxanthin, cryptoflavin and lycopene on the thickening of the common carotid artery intima, and found that among the studied carotenoids, Lutein and zeaxanthin have the strongest ability to reduce the thickening of common carotid artery intima.
The high purity lutein ester can be directly applied to edible oil to improve its color and nutritional value. It can also replace artificial pigment added to cream products, safe and healthy; After emulsification, lutein ester can be made into water-soluble pigment, which can be directly used in the coloring of beverages and water agents. Lutein esters can also be added to cosmetics to protect the skin from UV damage. At present, cognic company develops products in this field.
High purity lutein ester as the main material, adding some excipients and carriers, can be made into different content of hard capsules, soft capsules, tablets, oral liquid and other forms of human supplement, directly ingested by the human body, improve the level of human health.
With the deepening of the research of lutein and lutein ester in medical clinic, the role of lutein ester in the treatment of diseases is prominent, then the preparation of drugs with lutein ester as the main component will appear.
The natural high purity lutein ester has better stability than the free lutein, and the human body's absorption of it is also better than the free lutein, so the application of natural high purity lutein ester in food, health products and drugs will have a broader prospect. Therefore, the research, application and development of lutein esters will have far-reaching significance and value.
