The origin of free fatty acids formed in frozen cape hake mince ( Merluccius capensis, castelnau) during cold storage at −18°C
Abstract Hake mince was stored at −18°C and samples were withdrawn at intervals during a 300‐day period. The extracted lipids were examined for free fatty acid (FFA) and phosphorus (P) content. Total FFA contents were corrected for a phospholipid contribution and converted into genuine FFA contents....
