Studies to Determine the Nature of the Damage to the Nutritive Value of Menhaden Oil from Heat Treatment

Abstract
The non-adduct-forming fraction (NAFD) of the distillable esters from heated menhaden oil was toxic to rats to a degree comparable with the toxicity of the similar fract on from heated linseed oil. The adduct-forming fraction (AFD) of the distillable esters from the heated oil was nutritionally innocuous. The results provide some additional evidence for an association between the toxicity of the NAFD fraction and the presence of polyene acids in the original oil.
