Claims6
A process for extracting astaxanthin from Haematococcus pluvialis algal biomass, comprising:
- providing a dried form of Haematococcus pluvialis cells;
- extracting astaxanthin using supercritical fluid extraction with one of at least a polar and non polar solvent to obtain a slurry;
- filtering the slurry to separate the cells from the extract;
- and
- obtaining an astaxanthin oleoresin concentrate by filtering and distilling to remove solvent from the extract, wherein the steps of extracting, filtering, and distilling occur under an oxygen free nitrogen atmosphere.
2 more elements
A process for producing astaxanthin oleoresin, comprising:
- obtaining an algal powder of dried Haematococcus pluvialis cells;
- cracking the algal powder to form cracked cells;
- extracting astaxanthin from the cracked cells using supercritical fluid extraction with one of at least a polar and non-polar solvent to obtain a slurry;
- filtering the slurry to separate the cells from the extract;
- and
- distilling the filtrate to remove the solvent and produce an astaxanthin oleoresin, wherein the steps of extracting, filtering, and distilling occur under an oxygen free nitrogen atomsphere.
