In addition to the artificial chemical synthesis, natural astaxanthin biological sources generally has 3 kinds,aquatic products processing industry waste, red yeast Phaffia rhodozyma (Phaffia rhodozyma) and microalgae (Haematococcus pluvialis).
Among them, the astaxanthin content of waste in the lower, and the extraction of high cost, not suitable for large-scale production.
The average content of natural astaxanthin by phaffiarhodozyma also is only 0.40%. In contrast, Haematococcus pluvialis in astaxanthin content is up to 1.5% ~ 3%, so it is regarded as the product of natural astaxanthin concentration .
