luteeroteollisuudessa

Luteeroteollisuudessa refers to the industrial production of lutein. Lutein is a xanthophyll carotenoid, a type of pigment found naturally in plants, particularly in dark green leafy vegetables like spinach, kale, and collard greens, as well as in egg yolks and some flowers. Industrially, lutein is primarily extracted from marigold flowers (Tagetes erecta).

The luteeroteollisuudessa process typically involves harvesting marigold flowers, drying them, and then extracting the lutein using various solvent-based methods. Common solvents include hexane, ethanol, or supercritical carbon dioxide. After extraction, purification steps are employed to isolate lutein and remove other compounds. The resulting lutein can be in the form of oleoresin, crystalline powder, or beads, depending on its intended application.

The primary use of industrially produced lutein is in the dietary supplement industry, where it is valued for its antioxidant properties and its role in eye health. Lutein, along with its isomer zeaxanthin, accumulates in the macula of the human eye, where it is believed to filter harmful blue light and protect against age-related macular degeneration (AMD) and cataracts. Beyond supplements, lutein is also used as a natural food coloring agent in various food products and in animal feed, especially for poultry, to enhance the yellow coloration of egg yolks and broiler skin. The demand for luteeroteollisuudessa has grown due to increased consumer awareness of its health benefits and the expanding market for natural food ingredients.
