Supercritical co2 extraction of African catfish (Clarias Gariepinus) oil and its fatty acid profile
The supercritical carbon dioxide extraction (SC-CO2) of fish oil was studied using the viscera and skin of African catfish as a raw material and the CO2 as supercritical fluid solvent. A central composite design of response surface methodology (RSM) was employed to optimize the SC-CO2 extraction...

| description | The supercritical carbon dioxide extraction (SC-CO2) of fish oil was studied using the
viscera and skin of African catfish as a raw material and the CO2 as supercritical fluid
solvent. A central composite design of response surface methodology (RSM) was
employed to optimize the SC-CO2 extraction variables. The response variable (Y) oil
yield was executed against the four independent variables namely pressure, temperature,
flow rate and the soaking time. The statistical analysis showed, pressure was the most
significant linear factor on oil yield. Furthermore, the oil yield was varied with the
interaction effects of pressure, temperature and flow rate. Optimum points were
obtained within the studied variables range at 65°C temperature, 35 MPa pressure, 2.6
mL/min flow rate and 3.6 h soaking time with maximum oil yield 66.96 and 40.6%
from viscera and skin, respectively. The principal fatty acids in terms of concentration
were oleic and docosahexaenoic acids respectively. The main objective of this study
was to optimize the extraction condition using least amount of CO2 consumption rate
and time with highest oil yield recovery and ensure the highest amount of fatty acid in
the SC- CO2 extracted oil. |
