Description
Summary:•Metabolic profiles of pufferfish meat were firstly illuminated by NMR.•The taste metabolites were in good agreement with sensory evaluation.•The process effects on pufferfish taste were partly explained by their metabolites. The difference of metabolite profiles between raw and cooked pufferfish (Takifugu flavidus) meat was explored by 1H NMR technique and multivariate statistical methods. The orthogonal projection to latent structure-discriminant analysis (OPLS-DA) results showed an obvious separation between two samples. There were 24 dominating metabolites in the pufferfish muscle extraction, of which 11 metabolites changed significantly (p
