Abstract

The need for softer processing of fish oil has become one of the major concerns in the refining industry. The deacidification efficiency of sardine oil/solvent mixture with different solvents was studied. Four solvents methanol, ethanol, propanol and acetonitrile were tested for their ability to deacidify sardine oil. At an oil/solvent ratio of 1:2, maximum reduction in free fatty acids (FFA) of 32.08, 30.8, 23.3 and 10.94 % was noted for methanol, ethanol, propanol and acetonitrile respectively. The influence of various solvent ratios, and their effects on the oil loss were also studied. The efficiency in deacidification was also characterised by the solvent traces in oil and reduced oil loss. Of all the tested solvents, methanol gave the highest reduction in the FFA levels while acetonitrile gave the lowest reduction in FFA.
