Discrimination and characterization analysis of key flavor compounds from Tianshui <i>Zanthoxylum bungeanum</i> shells and seeds by GC×GC-TOFMS and chemometrics.

ABSTRACT: Flavor compounds influence consumer acceptance of Zanthoxylum bungeanum Maxim (Chinese pepper) berries, so detailed knowledge of its sensory characteristics and flavor compound composition are vital for assessing sensory quality and conserving genetic resources. This study identified and characterized the key flavor compounds in Z. bungeanum shells (SH) and seeds (SD) from the seven growing regions of Tianshui city, Gansu province, using GC × GC-TOFMS and chemometrics. The flavor compounds identified in Z. bungeanum were in the compound classes of hydrocarbons, heterocyclic compounds, ketones, alcohols, esters, aldehydes and carboxylic acids. Multivariate statistical analysis distinctly differentiated between SH or SD samples from the seven regions. The key differentia
