Abstract
In order to investigate whether the lipid from mackerel waste juice can be used as a feed oil by removing toxic oxidized products or not, the POV, TBA value and fatty acid composition of lipid treated with Aspergillus terreus were compared with those of nontreated lipids. A 18h treatment with the mold decreased lipid, POV, and TBA value. Moreover, the percent of ω3 HUFA in total fatty acids increased markedly by the treatment. These findings suggest that the nutritive value of lipid from fish waste juice may be improved by the treatment with Asp. terreus.
