Function

Vision protection
Lutein is a kind of fat-soluble vitamin, and its absorption spectrum contains near blue-violet light, which can help the retina of the eye to resist ultraviolet rays. Lutein is an important antioxidant for the eyes. Supplementing a large amount of lutein to the human body helps to maintain the durability of vision, improve visual response time, and reduce visual damage. For myopia, supplementing lutein can delay the increase of myopia degree
coloration
Lutein is widely used in condiments, tobacco, cakes, confectionery and various feed processing. In China, lutein has been widely used as a colorant
Anti-oxidize effect
Oxygen free radicals in the human body are an important cause of many age-related diseases. Lutein has strong antioxidant capacity, which can inhibit the activity of oxygen free radicals and prevent the damage of oxygen free radicals to normal cells.
Anticancer effect
Lutein has unique biological effects in inhibiting tumor growth, and its mechanisms mainly include antioxidant activity, inhibition of tumor angiogenesis and cell proliferation, etc.
The effect of delaying early arteriosclerosis
The latest research findings found that lutein can slow the development of early arteriosclerosis. After animal experiments, it was found that the incidence of arterial thrombosis was lower than that of mice without lutein-containing diets when lutein was mixed with mouse feed and fed to them.
The role of diabetes prevention
Lutein can be used as an effective adjuvant to enhance the hypoglycemic function of insulin. Therefore, eating foods such as fruits and vegetables rich in lutein can reduce the risk of diabetes

High performance liquid chromatography
High-performance liquid chromatography is a highly sensitive, efficient and rapid separation method, which can accurately detect the content of various components in its samples, and is the most widely used detection method for quantitative analysis of lutein. . The method has high accuracy and good stability, and can efficiently and rapidly detect the content of lutein in samples  .
Colorimetry
Colorimetry is based on the Lambert-Beer law. The most common one is UV-Vis spectrophotometry, which is a simple, fast, and low-cost detection method, which is used for accurate analysis according to the concentration of the measured substance in direct proportion to the absorbance. This method cannot analyze different isomers of lutein, has poor sensitivity, and is susceptible to interference. These are the outstanding shortcomings of UV-Vis spectrophotometry, which seriously restrict its application and development.
