Lutein processing line

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 is not only a natural coloring agent, but also great material for supplements. Raw material selection: The main raw materials of lutein are green leafy vegetables and citrus fruits. When selecting, you need to consider the quality and yield of the raw materials to ensure that the lutein content in the raw materials is high enough. Extraction: Lutein is mainly extracted by solvent extraction. First, chop the raw materials and add them to the solvent for soaking. Then, through stirring and heating, the solvent is fully contacted with the lutein in the raw material to promote the lutein to dissolve in the solvent. Finally, the lutein in the solvent is separated by filtration and concentration. Purification: Depending on the extraction method and desired purity, further purification steps may be employed. These can include techniques like precipitation, chromatography, or membrane filtration to isolate and purify specific compounds. Concentration: The filtered extract may undergo a concentration process to increase the concentration of the desired compounds. This can be achieved through techniques like evaporation or vacuum distillation, which remove the solvent and concentrate the active components.
