In recent years, great attention has been focused on rapid, selective, and environmentally friendly extraction methods to recover pigments and antioxidants from microalgae. Among these, supercritical fluid extraction (SFE) represents one of the most important alternatives to traditional extraction methods carried out with the use of organic solvents. In this study, the influence of parameters such as pressure, temperature, and the addition of a polar co-solvent in the SFE yields of carotenoids and fat-soluble vitamins from T. obliquus biomass were evaluated.

Amaranthus spp. (Amaranthaceae family), known as amaranth, are plants native of Central America, today produced in many parts of the world. due to their popularity popular as a health food. Because of its composition, amaranth can be considered to be attractive not only as a food but also for pharmaceutical and cosmetics uses.
