The quality of fish oil, as reflected by its free fatty acid (FEA) content, was studied in relation to the processing conditions offish meal manufacture from anchovy (Engraulis caixnsir). Six samples of anchovy lipids were isolated from consecutive stages of the process and analysed for fatty acid c

The free fatty acid (FFA) content of anchovy oil and the residual lipids in anchovy meal were studied as a function of the length and temperature of the delay between catching and processing the fish. It was found that there was a

Long-term storage of fish oils frequently leads to deterioration in quality due to enzymatic formation of free fatty acids (FFA). The present investigation has identified a number of chemical characteristics which can serve as indices in predicting which oils arc liable to show FFA escalation on sto
Anchovy were stored at 17Β°C. 8Β°C. 0Β°C and -6Β°C. Samples were withdrawn periodically and the extracted lipids analysed for free fatty acids (FFA) and phosphorus (P) content. From the results of these analyses it was possible to calculate the rates of enzymatic hydrolysis of the phospholipids and the
In this report evidence is presented that the rapid rise in the free fatty acid (FFA) content of fish oils during storage is due to contamination of the oils by bacteria belonging to the genus Alcaligenes.
