iOil from chia seeds is rich in fatty acids omega -3 and omega-6
and these may be obtained by supercritical extraction with CO2.
Using this method the final extract is free of solvent. The combination
of P = 408 bar and T=80◦C, provided the best yield (7.18%)
among the tested conditions. Pressure has a more significant
effect than temperature on the extraction yield. The kinetic curve
obtained let us suppose a maximum yield of 25% with an extraction
time of 10 h. The concentration of key compounds omega-3
and omega-6 do not decrease with the increment of temperature
and pressure in the tested range.
