Highlights • Green tiger shrimp shell, a waste, is a good source of astaxanthin.• Astaxanthin extraction and properties depend on the solvent and method of extraction.• Polar/nonpolar combinations help to improve the extraction efficiency.• Ultrasound extraction (UAE) was optimized for astaxathin extraction using RSM.• UAE is an effective green extraction method for astaxanthin from shrimp shells.
