Abstract

Free astaxanthin one-solvent extractions with ethanol, acetone, and liquid 1,1,1,2-tetrafluoroethane from raw and lactic acid fermented (ensilaged) shrimp residues were investigated. The total carotenoid recovery from ensilaged shrimp wastes was higher than that from non-ensilaged ones as assessed by HPLC analyses. Acetone gave the highest extraction yields of free astaxanthin with up to 115 microg/g of material. Moreover, liquid tetrafluoroethane is reported for the first time in a successful one-solvent extraction of carotenoids from shrimp.

摘要

研究了用乙醇、丙酮和1,1,1,2-四氟乙烷从生虾残渣和乳酸发酵（青贮）虾残渣中进行虾青素单溶剂萃取。通过高效液相色谱分析评估，青贮虾废弃物中总类胡萝卜素的回收率高于未青贮的虾废弃物。丙酮对游离虾青素的萃取产率最高，可达每克原料115微克。此外，首次报道了用1,1,1,2-四氟乙烷从虾中成功进行类胡萝卜素单溶剂萃取。
