Description
Marigold is an annual herb belonging to the Asteraceae family, native to Mexico. Extracts of this plant, especially lutein and carotenoids, are widely used in food, medicine, cosmetics and poultry feed.
The main components of marigold extract are lutein and zeaxanthin, pigments that co-exist with zeaxanthin in nature. Lutein and zeaxanthin are the main components of plant pigments that make up corn, vegetables, fruits, flowers, etc. They are also the main pigments that make up the macular region of the retina of the human eye. The human eye contains high amounts of lutein and zeaxanthin, but these elements cannot be manufactured by the body and must be supplemented by foods containing lutein and zeaxanthin. Deficiency of these two elements may lead to eye diseases such as vision loss and cataracts.
Lutein is characterized by antioxidant, high stability, non-toxicity and high safety, so it is widely used in food additives and new food ingredients. It can be used in common foods, such as eye-care soft candies and children's supplements. In addition, lutein is also used in feed additives, such as poultry fattening and egg laying.
In China, marigold extract is one of the sources of food additives and new food ingredients, in which lutein is stipulated as a normative standard for food additives. Also, marigold extract is allowed to be used in feed as an additive for poultry fattening and egg production.
Function:
1. Lutein in marigold extract is an excellent colorant and functional nutritional enhancer.
Studies have shown that adding a certain amount of marigold extract to chicken feed can significantly improve the color of chicken shins, carcass and belly fat. At the same time, marigold extract can also improve broiler shin coloring and increase the value of chromaticity extremely significantly with the growth of time, but the degree of color growth decreases extremely significantly with the growth of time.
2. Marigold extract can be used as a feed additive to improve the body color of farmed fish, shrimp and ornamental fish.
This extract can be directly deposited in the scales, skin, adipose tissue and eggs, such as pondweed, Chinese soft-shelled turtle, etc.; it can also be converted into astaxanthin and then deposited in the tissues, such as Atlantic salmon, goldfish and so on. In addition, fish are able to synthesize melanin on their own, but cannot synthesize carotenoids from scratch, so they must consume different sources of carotenoids from their feed.
3. Marigold extract also has antioxidant and anti-inflammatory effects.
Due to its rich content of polyphenolic compounds and multivitamins, it scavenges free radicals and protects cells from oxidative damage. It also has excellent anti-inflammatory properties that can effectively relieve skin inflammation and allergic reactions. These properties make marigold extract have a wide range of application prospects in the field of agriculture, which can not only improve the health condition and growth performance of animals, but also enhance the disease resistance and antioxidant capacity of plants, and improve the quality and yield of agricultural products.
