Natural Pigment Bulk Food Grade Lutein Powder
Specifications: Lutein 5% 10%, 20%, 40%, 50%
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.
Lutein has a lot of health benefits. It has antioxidant property, and it may scavenge free radicals, support eye health, protect skin from ultraviolet ray damage, reduce the risk of suffering diabetes, and inhibit the increase of cancer cells.
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.
Lutein can also be used as addtives to feeds for poultry, fish and shrimps.
