Lipase‐Assisted Concentration of n‐3 Polyunsaturated Fatty Acids from Viscera of Farmed Atlantic Salmon ( Salmo salar L.)
ABSTRACT: In fish processing, viscera are generally considered waste products and often discarded. Our research objective was to use Atlantic salmon ( Salmo salar L.) viscera as a source of fish oil and to increase its concentration of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) by li...
