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 CO 2 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.

Determination of functional compounds in blue shark (<em>Prionace glauca</em>) liver oil obtained by green technology

“…For this work, a statistical strategy was used with 3 replicates and a 5 × 2 factorial design, covering 5 pressures and 2 temperatures, totaling 30 trials (Table 2). The choice of pressures and temperatures was made based on a study on cobia liver published by this research group (Santos et al, 2016).…”

Quality of red tilapia viscera oil (Oreochromis sp.) as a function of extraction methods

“…Different methods have been used for extracting oil from the viscera and, in general, from fish farming waste, such as: enzymatic hydrolysis [ 9 ], biological silage [ 10 ], pressing of fish waste, wet pressing [ 11 ], supercritical fluid extraction [ 12 ], solvent extraction [ 13 ] among others [ 14 ]. Most of these methods have high investment costs or long process times, which has prevented their implementation at small or moderate scale production systems.…”

Aspectos do desenvolvimento do cultivo do bijupirá Rachycentron canadum no Brasil e no mundo

“…A escolha do bijupirá como alvo da piscicultura marinha se deve principalmente a sua alta taxa de crescimento (DOMINGUES, 2012) pode alcançar 10 kg em 1 ano. Devido a estes atributos, esta espécie tem sido amplamente utilizada na aquicultura em alguns países da Ásia e região do Pacífico (ZHOU et al, 2006;GOPAKUMAR et al, 2011;SAKTHIVEL et a., 2012;SANTOS et al, 2016). Nesse contexto a China continental (pelo menos Hainan e Fujian) também possui produção comercial; Guangdong reporta um volume menor em sua produção, mas significativo (HUANG et al, 2011).…”
