•Astaxanthin (ASX) was successfully extracted from shrimp waste by green solvents.•Sunflower oil (SF) and its methyl ester (ME-SF) were used as green solvents.•The effect of temperature and solvent/waste ratio on ASX yield was investigated.•Freeze drying shrimp waste before extraction decreases ASX yield.•SF and ME-SF extract 60% and 80% of total ASX content, respectively. In this work, sunflower oil (SF) and methyl ester of sunflower oil (ME-SF) were introduced as two green solvents for extracting astaxanthin (ASX) from shrimp processing waste. The effects of temperature (25, 45, 70°C), solvent to waste ratio (3, 6, 9), waste particle size (0.6 and 2.5mm) and moisture content (0% and 86.8%) as well as stirrer speed (120, 200, 400rpm) were studied during the process. In all the experiments, ASX yields from extraction with ME-SF were higher than with SF. For both solvents, the highest ASX content using a short extraction time was achieved at a temperature of 70°C, a solvent to waste ratio of 9 and a stirrer speed of 400rpm while the waste particle size and moisture content were 0.6mm and 86.8%, respectively. ME-SF and SF seem promising solvents extracting respectively about 80% and 60% of the total ASX extracted by organic solvents.
