Abstract

•A simple and accurate GC method was developed for determination of tetramethylpyrazine and acetoin in vinegars.•Tetramethylpyrazine in vinegars follows second-order polynomial models of acetoin and ammonium concentrations.•Acetoin and ammonium were deduced to be the precursors of TMP in vinegars by isotopic tracing.
