Overview

Comprehensive review uncovers over 2000 volatile organic compounds and key fermentation microbes in Liupao tea, highlighting the metabolic drivers of its aged aroma profile.

Key Points

  • To synthesize current evidence on the chemical profiles, key odor-active compounds, and microbial metabolic pathways that generate the distinctive aroma of fermented Liupao dark tea.
  • Reviewed chemical profiling studies documenting volatile organic compounds (VOCs) and key odor-active compounds (KOACs) identified via gas chromatography–olfactometry (GC-O) and odor activity values (OAV).
  • Analyzed the functional roles of fungal and bacterial communities in driving enzymatic aroma formation during fermentation and aging.
  • Liupao tea contains over 2000 documented VOCs—principally alcohols (368), hydrocarbons (357), and ketones (351)—substantially exceeding the approximately 1000 compounds typically found in other dark teas.
  • Key odor-active compounds including alcohols, aldehydes, and methoxybenzene derivatives generate signature floral, fruity, aged, and stale sensory notes through metabolic activities of fungi (e.g., Aspergillus, Penicillium) and bacteria (e.g., Burkholderia).
