Supercritical CO 2 Extraction of Oil and Residual Proteins from Atlantic Mackerel ( Scomber scombrus ) as Affected by Moisture Content
Year: 1997
Type: article
Abstract: ABSTRACT Lipid composition of supercritical CO 2 (SC‐CO 2 ) extracts, residual oil in muscle and changes in sarcoplasmic proteins after extraction of Atlantic mackerel were characterized. Dehydration of the muscle to 10.2% (w/w) resulted in high oil yield with minimum changes in protein content and composition. Sarcoplasmic protein content of fish muscle following SC‐CO 2 treatment was lower than that of original muscles at all moisture levels (3.8–64%, w/w). Analysis of sarcoplasmic proteins by capillary electrophoresis indicated aggregation of low molecular weight proteins during SC‐CO 2 extraction. SC‐CO 2 ‐extracted muscle also had lighter color than original samples. The SC‐CO 2 extraction showed potential to provide high quality oil and protein meal.
