Description
Yuan Cao and co-authors extract astaxanthin, a red antioxidant pigment, with a green solvent and ultrasound, in a 2026 paper. The pigment comes here from a yeast used in supplements. Deep eutectic solvents can replace harsher organic reagents, and ultrasound helps break cells so the pigment flows out.
Six solvent blends were tried, and a menthol plus acetic acid blend won. Tuning power, time, and heat gave a top extraction rate well above most organic solvents in the test. Microscopy showed the treatment punched pores in the yeast cells, which sped release. The extract was also checked for anti aging activity, with no major safety signal in the part of the head shown.
