Extraction processes has been abundantly studied for astaxanthin from Haematococcus pluvialis by testing different technologies such as extraction by using organic solvent as ethanol, acetone, hexane and chloroform and methanol mixture (1:1 v/v)(Molino et al., 2018a) or by new unexplored solvent as butanol, cyclohexane, ethyl acetate (Samori et al., 2019), extraction by supercritical fluids by using CO2 (Sanzo et al., 2018), acid pre-treatment and homogenization (Kang et al., 2008) with the aim of improving extraction astaxanthin yield.	cache/cet-10848.pdf	txt/cet-10848.txt
