Impact of dietary plant protein levels on the volatile composition of Senegalese sole (Solea senegalensis Kaup, 1858) muscle

► The volatile profile of sole fed different dietary protein levels was evaluated through HS-SPME coupled to GC-IT/MS. ► Twenty compounds were quantified. ► 1-Penten-3-ol, hexanal and (E)-2-nonenol were present in the highest concentration. ► Fish meal replacement by plant proteins has no major effects on sole's muscle volatile composition.
