Haematococcus pluvialis is a kind of green algae, belonging to the order Chlorella, Haematococaceae. Under favorable natural conditions, Haematococcus pluvialis is green and swimming. When the environment becomes bad (such as ultraviolet radiation, lack of food, or extreme weather), the cells of Haematococcus begin to accumulate a large amount of astaxanthin and enter the red "hibernation period". Astaxanthin as a protective barrier for Haematococcus cells can make the cells survive for 40 years in the absence of food and moisture. When the natural environment becomes better, water is sufficient, and nutrients are suitable for growth, it will regain vitality. It can be seen that the natural astaxanthin has a strong ability to protect cells!
In nature, Astaxanthin is commonly found in microalgae and phytoplankton, and it also exists in shrimp and crab as a food chain. Haematococcus pluvialis is the most abundant source of astaxanthin in nature. Astaxanthin contains 1.5g to 2.5g per 100g of haematococcus powder, while astaxanthin is extremely high in shrimp and crab and other fish Low, negligible, so people obtain natural astaxanthin by cultivating Haematococcus pluvialis.
After harvesting, the high-quality Haematococcus pluvialis is washed, broken, and dried to obtain Haematococcus pluvialis powder, and then natural astaxanthin with anti-oxidant capacity is extracted from it. The methods for extracting astaxanthin from Haematococcus pluvialis powder include supercritical CO2 extraction technology and organic solvent extraction technology. However, astaxanthin obtained by organic solvent extraction technology generally has residual organic solvents, low safety, and harms human health; the most advanced extraction process is supercritical CO2 extraction technology. This method has a high extraction rate and guarantees no Residual solvents and high safety.
