The oxidation of fish oil during extraction process and storage

The results have shown that the method NMKL-No.131 had provided highest extraction yield, but the oil had been the most oxidized. Meanwhile, the mechanical method provided lower extraction yield, but the quality of the product was much more better, met the requirements of commercial fish oil product. The addition of ginger and tea extract to fish suspension before extraction lowered the peroxide value of extracted fish oil significantly.
