With people's attention to health care, astaxanthin has gradually become a popular health product. Astaxanthin is one of the main carotenoids in marine organisms. Astaxanthin has the strongest antioxidant activity in nature. Astaxanthin can combine with protein in the body to appear blue and blue. It has the effects of anti-oxidation, anti-aging, anti-tumor and prevention of cardiovascular and cerebrovascular diseases. Astaxanthin comes from microalgae known as red algal coat, which is extremely rich in polar marine environment and is a natural carotenoid (from yellow to red, including carotene and qinjiaohuang). Business nutritionists have confirmed that astaxanthin can cross the barrier from blood to brain, so astaxanthin can protect the brain, central nervous system and eyes. Astaxanthin also has other effects: improving physical endurance and reducing the risk of muscle damage; Relieve eye fatigue symptoms and improve visual sensitivity; Reduce wrinkles through internal replenishment; Relieve the symptoms of hyperpigmentation (commonly known as age spots); Regulate cytokines and inhibit gene expression of inflammatory cytokines and chemical factors; Improve gastric health and alleviate infection or inflammation caused by Helicobacter pylori . It can be seen that astaxanthin is a natural extract with superior health functions. However, astaxanthin comes from a wide range of sources. Besides algae, fish, shrimp, crab and shellfish contain astaxanthin. Which raw material can extract the safest astaxanthin with the highest content?
From the perspective of dietary health, the closer the food chain is to humans, the lower the astaxanthin content of food organisms containing astaxanthin, the more by-products harmful to human health (such as paragonimiasis, avian influenza, etc.); The further away the food chain is from humans, the moreastaxanthinThe higher the astaxanthin content of food organisms, the safer. Therefore, extracting pure astaxanthin from algae is the safest food containing astaxanthin with the highest content. Haematococcus pluvialis is recognized as the best organism to produce natural astaxanthin in nature. Therefore, extracting astaxanthin from this microalgae undoubtedly has broad development prospects and has become a research hotspot in the production of natural astaxanthin in the world.
Haematococcus pluvialis mainly grows and distributes in small ponds and small temporary blisters formed by ponding after rain in nature. It is the microorganism that synthesizes and accumulates astaxanthin most in nature. Haematococcus pluvialis has strong adaptability to the environment: under suitable growth conditions, it grows and reproduces rapidly with flagellated swimming cells; When the conditions become bad, the swimming cells of Haematococcus pluvialis will lose flagella, thicken the cell wall, and accumulate a large amount of red substances, thus the cells enter a dormant state. After 40 years of dormancy, the cells still have activity. Under appropriate conditions, they can reproduce and produce new green cells. The tenacious vitality and environmental adaptability of Haematococcus pluvialis have aroused great interest in the scientific community. Scientists preliminarily speculate that the red substances in Haematococcus pluvialis cells may play a key role. 1944 British biology The chemist tisher first confirmed that this red substance is astaxanthin. McPherson astaxanthin is a kind of carotene. Since the 1990s, domestic surgical circles have paid great attention to it and done a lot of experimental research. The results show that astaxanthin is the strongest natural antioxidant found so far, and its antioxidant capacity is 550 times that of vitamin E! It is thanks to the protective shield of astaxanthin that Haematococcus pluvialis has strong vitality.
