What is Carotenoids Powder?
Carotenoids Powder is commonly found in yellow, orange, and red pigments. It has light absorption that only absorbs blue-violet light, and the light absorption is the strongest within 400~500 nm. The conjugated double bond structure of carotenoids determines the color change of its existence, and the more conjugated double bonds it contains, the closer the color is to red. In addition, studies on citrus, tomato, loquat, and wolfberry have shown that different carotenoid contents can cause color changes.

What are the classifications of Carotenoids Powder?
At present, more than 700 kinds of carotenoids have been discovered in nature. About 60 of them exist in foods such as fruits and vegetables in people's daily diet. In addition, there are also some in human blood.
Carotenoids can be divided into carotene and lutein according to their chemical structure, elemental composition, and physicochemical properties. Carotene is composed of two elements, carbon and hydrogen, specifically includes α-carotene, β-carotene, γ-carotene, and lycopene. Lutein is composed of three elements, carbon, hydrogen, and oxygen, which can form epoxy, hydroxyl, ketone, carboxyl, methoxy, and other oxygen-containing functional groups, such as lutein, zeaxanthin, violaxanthin, and astaxanthin, etc. Carotenoids are divided into provitamin A carotenoids and non-provitamin A carotenoids according to the role of provitamin A. Provitamin A carotenoids include alpha-carotene, beta-carotene, and beta-cryptoxanthin. Non-pro-vitamin A carotenoids include lutein and zeaxanthin.
What is the source of Carotenoids Powder?
Research has found that natural carotenoids are found in nature. It is ubiquitous in plants, and in small amounts in fungi, algae, bacteria, and a few animals. The human body cannot synthesize carotenoids independently, and can only be obtained from foods such as fruits and vegetables.
1 Distribution in plants
Carotenoids are found in most plants. However, the types and proportions of carotenoids contained in different plants and even different parts are different. In plant leaves, carotenoids, as photosynthetic auxiliary pigments, coexist with the chlorophyll in the form of photosynthetic pigment-protein complexes and participate in photosynthesis. In addition, the petals or fruits of plants appear orange, yellow, and red, such as carrots, citrus, tomatoes, and other fruits and vegetables, which are caused by the presence of carotenoids.
2 Distribution in microorganisms
Carotenoids are also present in microorganisms such as fungi and bacteria. The representative ones are yeast, mold, Rhodospirillum, and so on. Because microorganisms have the characteristics of fast growth, low nutritional requirements, and low environmental requirements. Using microorganisms to produce natural carotenoids can greatly improve production efficiency. At present, the fungi that use microorganisms to produce more carotenoids are yeasts and molds. The most commonly used bacteria are photosynthetic bacteria. Bacteriochlorophyll is a structure similar to plant chloroplasts with double membranes in photosynthetic bacteria, which mainly contain carotenoids such as rhodopsin and lycopene.
3 Distribution in algae
Algae also contain carotenoids, especially beta-carotene. At present, the use of fungus, spirulina giant, Houttuynia cordata, Dunaliella, etc. can be used to produce high carotenoids.
4 Distribution in animals
Fish, fish eggs, and invertebrates, such as salmon, shrimp, and mollusk shells, are rich in carotenoids, mainly canthaxanthin and astaxanthin. Carotenoids are also found in cows and their subsidiary products such as milk, cream, and cheese. Generally related to seasonal changes, carotenoid content is high in early summer when high-quality forages are eaten in large quantities.
