Nutrivitas®Lutein Ester Health Benefits:

Nutrivitas®Lutein Ester is an important carotenoid fatty acid ester, most of the naturally occurring lutein esters can be divided into trans lutein ester and cis lutein ester, basically the all-trans molecular configuration is dominant. All-trans lutein esters can be divided into lutein monoesters and lutein diesters.

■ Source

Lutein esters are common in plants such as marigold flowers, pumpkin, kale and primrose. The most abundant of these is found in marigold flowers, where it can be as high as 30 to 40 per cent. In marigolds and other plants, lutein is usually combined with fatty acids (e.g. lauric acid, palmitic acid, etc.) to form esters.

Production technology description:

●The preparation methods of lutein ester generally include solvent extraction method, supercritical CO2 extraction method and chemical synthesis method. In the solvent extraction method, marigold flower seeds were dissolved in n-butane or acetone to extract the active ingredients, and adsorbents were added to remove heavy metals and pesticide residues, and then the solvent was removed by vacuum drying to obtain the concentrate. The concentrate was dissolved in isopropanol or butanol, crystallised at reduced temperature, washed and finally dried with the addition of antioxidants to obtain high purity lutein esters. Supercritical CO2 extraction was carried out using supercritical CO2 for three-stage extraction using lutein ester extract as the raw material. The chemical synthesis method was synthesised using organic solvents or reacted with succinic anhydride, using soybean meal as a catalyst and optimising the reaction conditions to obtain high conversion luteolin disuccinate.

▶ Food field

▶ Pharmaceutical field

Nutrivitas®Lutein Ester is used as a preventive or adjunctive treatment for eye diseases such as age-related macular degeneration (AMD); as a pharmaceutical agent in combination with other nutrients (e.g. zeaxanthin) to enhance therapeutic efficacy.

Nutrivitas®Lutein Ester Applications:

Nutrivitas®Lutein Ester is used as a natural colourant in bakery products, dairy products, beverages, confectionery, etc. to give products a brilliant golden yellow colour. Nutrivitas®Lutein esters are used as nutritional enhancers, added to baby food, ready-to-eat cereals, etc. to supplement the requirement for lutein. Lutein esters have the functions of eye protection, antioxidant and immune enhancer and are widely used in capsules, tablets, functional candies and oral liquids.

Nutrivitas®Lutein Ester is absorbed by the body and broken down into free lutein, which supplements the macular pigment density in the macular region of the human retina, protecting the macula and promoting macular development. It protects the eyes from light damage, slows down the ageing of the eyes and prevents lesions. Protects vision, relieves symptoms of visual fatigue, prevents macular degeneration and retinitis pigmentosa, and reduces the production of vitreous warts.

Nutrivitas®Lutein Ester promotes antigen-stimulated lymphocyte proliferative responses and may influence the functional expression of cell surface molecules. It has a regulatory effect on cellular immunity.

Nutrivitas®Lutein Ester has a powerful antioxidant effect that can scavenge free radicals in the eye and reduce oxidative damage, helping to prevent cardiovascular sclerosis, coronary heart disease and tumours caused by ageing.

■ Structural properties

The backbone of Nutrivitas®Lutein Ester consists of two six-membered carbon rings linked by a long chain of conjugated double bonds containing 18 carbon atoms. Lutein esters occur in nature mainly in the all-trans molecular configuration, and the conjugated double bonds are arranged linearly to increase molecular stability. The stability of lutein ester is greater than that of lutein, and it is only under the influence of high temperatures, strong acids, iron ions and oxygen that lutein ester is more susceptible to damage.The conjugated double bonds in the long chain of lutein esters give the molecule strong antioxidant properties, effectively neutralising free radicals, and the conjugation system is involved in light absorption, filtering out blue light (wavelengths of 400-500 nm) to protect the retina. The conjugated system is also involved in light absorption, filtering out blue light (wavelength 400-500 nm) to protect the retina.

▶ Skin protection

Nutrivitas®Lutein Ester is not only good for the eyes, they also protect the skin from UV rays by absorbing UV rays, reducing UV damage to the skin and preventing skin ageing and discolouration.
