4. Conclusion
This is the first report of SFE of an x-3 PUFA rich oil from Northern
shrimp processing by-products. This solvent-free oil obtained
by SFE contains levels of EPA and DHA comparable to conventional
solvent extraction. Because it is a higher quality product it warrants
further investigation as a natural health product and clinical
evaluations for safety and efficacy. As this is a preliminary study
showing the viability of the method, further optimisation of SFE
parameters and pilot scale up would be the next logical step.
