Supercritical Extraction of Cobia (Rachycentron canadum) Liver Oil as a New Source of Squalene

Abstract

Cobia is a fish cultivated worldwide and there are few studies on the potential of their waste, such as the liver, it's rich in oil and active compounds. The objective of this study was to extract cobia liver oil (CLO) using supercritical CO2 under moderate temperature conditions (50, 60 and 70 °C, 250 bar) and characterize the oil (physico-chemical analysis, fatty acids profile and squalene content). The results showed that CLO is rich in MUFA and presented squalene, suggesting that this matrix can be applied in the production of high nutritional value oil.
