Natural Carotenoids

What is Natural Carotenoids?

As a micronutrient, Natural Carotenoids are widely found in plants, algae, bacteria, and fungi. There are more than 600 kinds of carotenoids discovered so far, and carotenoids can be found in a rich content in common fruits and vegetables, such as citrus, mango, and other fruits. of lutein. In addition, carotenoids, as fat-soluble pigments, determine the coloration of organisms to a certain extent. 

Among them, β-carotene and lycopene have significant antioxidant and immune-enhancing activities, so carotenoids have become key research objects in this field.

What are the characteristics of Natural Carotenoids?

Carotenoids are a class of C40 terpenoids and their derivatives are mainly composed of 8 isoprenoid units. All carotenoids contain polyisoprene structures, and most of them have multiple double bond structures symmetrical on both sides, so they have strong reducing power and electron transfer ability. It is unstable under the conditions of light, heating, and strong acid, and is prone to oxidation reactions to generate carotene cleavage products. Without the protection of antioxidants, the contents of lycopene and β-carotene decreased by 16. 71% and 28. 71%, respectively, within 3 months. 

At the same time, the hydrocarbon chain contains a conjugated double bond chromophore, which can absorb light of a specific wavelength and express a unique color. Some carotenoids have multiple isomers. For example, β-carotene contains more than 20 isomers, and the common ones are all-trans, 9-cis, 13-cis, and 15-cis. There are three common astaxanthin isomers, namely 3R, 3'R structure, 3R, 3''S cis structure, and 3S, 3'S structure. Most carotenoids are organic compounds containing hydroxyl, carbonyl, and methoxy polar groups, so they have greater solubility in highly polar organic solvents such as ketone, ether, and chloroform.

What is the synthesis method of Natural Carotenoids?

The body cannot synthesize carotenoids by itself. Therefore, carotenoids are obtained through external ingestion to meet the needs of the body. Common carotenoid synthesis methods mainly include chemical synthesis, plant extraction, and microbial culture.

Compared with chemically synthesized products, natural carotenoids are complex and often exist in isomers. Many studies have shown that the isomers of natural carotenoids can play a more effective role through interaction. For example, zeaxanthin is an isomer of lutein, and the two coexist in natural plants such as wolfberry and sour berry. When lutein and zeaxanthin were present in a ratio of 1:2, significant synergistic antioxidant activity was exhibited. Chemically synthesized carotenoids are mostly all-trans, which inhibits their absorption due to competition. In addition, by-products in the chemical production process increase the risk of diseases such as cardiovascular disease and increase safety hazards. Therefore, its application is limited. 

The source of plant extraction is limited, the composition is complex, and the processing steps such as extraction and purification in the later stage are cumbersome, and the production cost is high, which cannot meet the requirements of mass production. Single-celled microorganisms grow rapidly, have relatively simple nutritional requirements, and are rich in carotenoids in their products. The current research mainly focuses on the innovation of cultivation methods, harvesting, extraction, and purification methods, hoping to find a safe, cost-effective production method.

Natural Carotenoids Benefit:

Antioxidant

The conjugated double bond structure of carotenoids determines its strong reducibility. It plays an electron transfer role in the redox reaction so that carotenoids can effectively remove reactive oxygen species and reactive nitrogen generated by pathological processes or normal metabolism.

Effects on the immune system

Numerous studies have shown that carotenoids can affect immune responses at the protein or nucleic acid level through different pathways and improve immunity.

Carotenoids are provitamin A

As a fat-soluble vitamin, vitamin A is an indispensable micronutrient for normal metabolism and maintenance of the body. It has the functions of protecting eyesight, anti-infection, regulating immunity, and promoting growth and development.
