Abstract:

Volatile compounds in two kinds of Shanxi overmature vinegar during different aging periods were extracted through simultaneous distillation-extraction (SDE) and analyzed by GC-MS. Twenty-nine volatile compounds were identified to be acids, ketones, esters and herterocylic compounds. Among them, the contents of acetic acid, furfural, 3-hydroxy-2-butanone, 2,3-butanedione and tetramethylpyrazine were approximately 90%. The aging period had a significant effect on the number of volatile components. Therefore, a significant difference in aroma characteristics between 5-year-old vinegar and 8-year-old vinegar was observed. By formulating experiments, the major flavor compounds contributing to aroma characteristics of Shanxi overmature vinegar were confirmed.

Key words: Shanxi mature vinegar, Simultaneous distillation-extraction, Analysis, Formulate.
