After a systematic human safety test, an American company took Haematococcus pluvialis powder to supplement astaxanthin to two groups of healthy adults, with daily doses of 19.25mg and 3.85mg respectively. After the experiment, after detailed monitoring and comprehensive analysis, it was found that the oral Haematococcus pluvialis powder rich in natural astaxanthin had no pathogenic effect and toxic side effects on human body.
However, the chemical synthesis of astaxanthin may be polluted by other harmful substances, and the product also contains a large number of cis isomers, which reduces its bioavailability. Therefore, the application of chemically synthesized astaxanthin in food, feed, medicine and cosmetics is greatly limited.
Extended data 20 17 The global astaxanthin production is about 5 1 1.8 tons. Japan is the largest producing area, accounting for 47.22% of the global output. It is estimated that the output of China will reach 637.4 tons in 20 18. Driven by the rapid output growth in China, the global output increased by 122% in 20 18 years.
Among them, China Weihai Lida Biotechnology Co., Ltd. accounts for 52.74% of the global output and 29.94% of the output value, ranking first in the world. In terms of price, Cyanotech in the United States continues to be at a high level.
Due to the high technical difficulty and the limitation of algae species or strains, the output of natural astaxanthin is limited, which is far from meeting the market demand. Therefore, the large-scale production of natural astaxanthin by various biotechnology has been a hot issue at home and abroad. From 20 15, the market concentration of this industry is getting higher and higher.
In 20 18, the total output share of DSM in the Netherlands, Lida Biotechnology in Weihai, China and KLChemical in Japan was as high as 82.5 1%.
