Haematococcus Pluvialis is the best source of natural astaxanthin, also called Red algae extract. Many studies have shown that Haematococcus Pluvialis has a higher accumulation rate and total production of natural astaxanthin than other green algae. In Haematococcus Pluvialis, the proportion of astaxanthin and esters is close to aquaculture animals. This is a unique advantage compared with the extraction of astaxanthin from yeast by chemical synthesis. the structure of astaxanthin in Haematococcus Pluvialis is mainly 3S-3'S type, which is basically the same as aquatic objects such as salmon.
There are four cell forms of Haematococcus Pluvialis throughout the life cycle: small insect body, large insect body, glial sheath, and nematocysts. In a clean environment with sufficient nutrients, the large insect body occupies a leading position. When the environment turns bad, it will transform into a glial sheath body. Then into nematocysts with resistance. At this cell form, it begins to accumulate natural astaxanthin. They will become movable small insect bodies when the environment becomes adequately nutritious and then grow into a large insect body or glial sheath.
At present, Haematococcus Pluvialis is the best organism to produce natural astaxanthin. Therefore, extracting astaxanthin from it undoubtedly has broad development prospects, which has become the international natural astaxanthin production research hot spot.
