Marigold extract - not relying on "multifunctionality" to make a name for itself, but relying on its core ingredient Lutein to achieve a "dual monopoly" in the fields of "eye care and health" and "natural coloring".
Marigold is an important source of natural lutein, and the lutein in its extract far exceeds other sources (such as spinach and blueberries) in terms of inherent advantages, ingredient activity, efficacy compatibility, and compliance.
一、Natural advantages of marigold raw materials
There are many natural sources of lutein, but marigolds can become over 90% of the world's natural lutein supply, thanks to their inherent advantages of high content, easy extraction, and stable production capacity, which cannot be replaced by other plants
The lutein content of a single plant is more than 30 times that of spinach. The lutein ester content of high-quality marigold dried petals can reach 10-15 g/kg, while spinach is only 0.3-0.5 g/kg and blueberries are only 0.05-0.1 g/kg;
二、Advantages of Component Characteristics of Marigold Extract
1. Natural fat solubility------The lutein derived from marigold exists in the form of "lutein esters" and naturally has lipid soluble properties
2.Excellent stability------Natural lutein generally suffers from the problem of "easy oxidation", but the stability of lutein in marigold extract has been significantly improved through process optimization. The unpurified marigold lutein ester has an activity retention rate of over 90% after being stored at room temperature for 12 months under dark and sealed conditions;
3. Collaborative component support-----In addition to lutein, marigold extract also contains "zeaxanthin" (an isomer of lutein), which forms a natural synergy. zeaxanthin can enhance the antioxidant activity of lutein (with a 40% increase in free radical scavenging rate under synergistic effect), and the best eye protection effect is achieved when the deposition ratio of the two in the macular area of the eye is 10:1. Marigold extract naturally possesses this ratio;
三、The functional advantages of marigold extract
1. Eye protection effect, which is the core function of lutein
——Filter blue light: Lutein can absorb harmful blue light at 400-500nm, reducing the damage of blue light to retinal photoreceptor cells
——Protecting the macula：The macular area is the most sensitive area of the retina to light, and lutein is the core component of macular pigment. Lack of lutein can lead to macular degeneration
2. Natural coloring：In the fields of food and cosmetics, the natural yellow coloring advantage of marigold lutein is significant: strong coloring power————The coloring effect of 1g of marigold lutein is equivalent to 5g of lemon yellow, and the color can be adjusted from light yellow to orange yellow, suitable for baked goods, beverages, baby food and other scenarios;
3. Antioxidant：Although the antioxidant activity of lutein is not as good as that of grape seed extract, it excels in "targeting" and "safety":
——In skincare products, it can inhibit skin photoaging caused by ultraviolet radiation and reduce melanin production
——In health products, it can assist in protecting cardiovascular health and inhibiting low-density lipoprotein oxidation
The lutein in marigold extract can become the "dual material king", which is not supported by a single advantage: the inherent advantage of marigold's "high content and easy extraction" raw materials, combined with the "fat solubility and high stability" of lutein, form an "irreplaceable" competitive advantage.
