Marigold is the main raw material for the extraction of lutein and carotenoids, and the average yellow pigment content is not less than 12 grams per kilogram. This pigment is a pollution-free natural pigment.
Also known as "phytolutein", it exists together with zeaxanthin in nature. Lutein and zeaxanthin are the main components of plant pigments such as corn, vegetables, fruits, and flowers, and they are also the main pigments that constitute the macular region of the human eye. In nature, lutein is most abundant in dark green leafy vegetables such as kale, kale, spinach, and flowers such as calendula and marigold. Human eyes contain high amounts of lutein and zeaxanthin, but these two elements cannot be manufactured by the human body and must be supplemented by foods containing lutein and zeaxanthin. Without these two elements, the eyes will be blind.
Lutein and other carotenoids are thought to have antioxidant properties. Antioxidants protect cells from damage caused by free radicals, a damaging byproduct of normal metabolism. Free radicals in the body rob other molecules of electrons and damage cells and genes in a process called oxidation. Concentrated in the retina and lens, lutein protects vision by neutralizing free radicals and increasing pigment density. Lutein also has a shading effect against damaging glare.
Marigold extract is widely used in food, feed, medicine and other food industry and chemical industry. It plays an important role in improving product color and is an indispensable additive in industrial and agricultural production.

Marigold extract is an international common name, and is called "marigold lutein ointment" in my country. Its processing technology mainly adopts subcritical biotechnology low temperature leaching. First, the marigold flowers are harvested for fermentation and granulation, and then the marigold granules are fed into the extraction tank. After subcritical biotechnology low temperature leaching and mixed oil evaporation, the marigold extract (marigold lutein ointment) can be obtained.
