Astaxanthin extraction from Haematococcus pluvialis using CO2-expanded ethanol

•In-depth response surface analysis was done for scCO2 extraction of H. pluvialis.•Ethanol cosolvent affected extract’ antioxidant activity more than pressure or temperature.•We investigated a further increase in ethanol up to the region of gas-expanded liquids.•Astaxanthin recovery was larger in CO...
