Extraction of omega 3 fatty acids from sardine byproducts using supercritical carbon dioxide (SC-CO2)

Introduction: Sardine generally processed as canned fish, and in consequence of a lot of solid waste are generated as byproducts which could be good sources of fish oil. Omega-3 fatty acid compositions of total lipids extracted by supercritical carbon dioxide (SC-CO2) from sardine fish by-product (h...

Results: Highest yield was obtained from the skin (42.5%) followed by the head (22.4%) and the viscera (9.6%) which is closer to that of the yield of Soxhlet extraction method where 44%, 23% and 11% (on dry basis) oil were yielded from skin, head and viscera, respectively.

Docosahexaenoic acid (DHA) was characteristically major PUFA accounting 19.8% in head, 15.4% in skin and 13.6% in viscera of the total fatty acids.
