Abstract

The aim of this study was to determine differences among volatile compounds composition of Senegalese sole muscle fed with extruded diets containing different plant protein (PP) and vegetable oil (VO) sources. Two set of experiments were performed on growing sole. One growth trial used a control diet containing fish meal (FM) as the main protein source and different PP-based diets. Another growth trial compared a control diet containing fish oil (FO) as the main lipid source and different VO-based diets; after a period, all sole were fed with the FO diet. Results showed that the incorporation of PP sources up to 75% allowed the production of a similar content of major volatile compounds to the control diet. In VO-based diets, some significant differences were found in the levels of some volatile compounds in sole muscle; however, no significant differences were obtained through sensory evaluation.
