Marigold Extract Powder
Lutein is extracted from marigold flower. Lutein is kind of Xanthophyll and one of naturally occurring Carotenoids. Usually lutein coexists with its isomer zeaxanthin, and they can be interconverted in the body. Lutein is synthesized only by plants. Humans and mammals must obtain lutein from food.
Lutein powder has yellow-red color, and it is insoluble in water and propyl glycol; slightly soluble in vegetable oil and n-hexane; soluble in ethanol, and carrene; easily soluble in ethyl acetate, tetrahydrofuran and chloroform. Lutein is unstable to light and hydrogen, and it has to be stored in sealed, cool, dark and dry condition.
Natural Pigments are food pigments obtained from natural resources. Pigments extracted mainly from animal and plant tissues and microorganisms (culture), of which plant-based colorants are the majority. Natural pigments not only have the function of coloring food, but also have physiological activity.

Production Process：
Marigold petals → freeze-drying → crushed and sifted → proportionally added ethanol solution of extractants THF and KOH, and reacted at room temperature under nitrogen protection → filtration → Leaching → Concentration → Paste → dissolved in ethanol aqueous solution (volume ratio 1:1) → Adjusted pH value of extraction solution with acetic acid to neutral → centrifuged supernuant → lutein coarse product.
Lutein is an important Antioxidant , a member of the carotenoid family (a group of naturally occurring fat-soluble pigments found in plants), also known as "phytolutein", which co-exists in nature with zeaxanthin.
(1) The main pigment components of the retina: lutein and zeaxanthin constitute the main components of vegetable, fruit, flowers and other plant pigments, and are also the main pigment of the macular area of the retina of the human eye. Human eyes contain a high amount of lutein, this element is not produced by the human body, must rely on intake of lutein to supplement, if the lack of this element, the eye will be blind; Lutein structure；
(2) Protect the eyes from light damage, delay the aging of the eyes and prevent lesions: ultraviolet and blue light in the sun into the eyes will produce a large number of free radicals, leading to cataracts, macular degeneration, and even cancer. Ultraviolet light can generally be filtered out by the cornea and lens of the eye, but blue light can penetrate the eye to the retina and macula, and lutein in the macula can filter out blue light to avoid blue light damage to the eye. The fatty outer layer of the macula is particularly vulnerable to oxidative damage from sunlight, so this area is prone to degradation;
(3) Antioxidant helps prevent cardiovascular sclerosis, coronary heart disease and tumor diseases caused by aging;
(4) Vision protection: lutein as an antioxidant and photoprotective effect, can promote the regeneration of Rhodopsin in retinal cells, can prevent severe myopia and retinal detachment, and can improve vision and protect vision. Especially suitable for students, drivers and other people to eat;
(5) Relieve the symptoms of visual fatigue (blurred vision, dry eyes, eye distension, eye pain, photophobia, etc.);
(6) Improve the pigment density of macula, protect macula and promote the development of macula;
⑺ Prevent macular degeneration and retinitis pigmentosa;
(8) Reduce the production of glass membrane warts and prevent the occurrence of AMD.
Application ：
1. Healthcare Products. The lutein powder can be used in the healthcare products for eyes.
2. Colorant pigment powder.Lutein is primarily used as a colorant in food and supplements due to its yellow-red color. It appears yellow at low concentrations and orange-red at high concentrations.
3. Feed additives.Lutein can also be used as addtives to feeds for poultry, fish and shrimps.
