Description
A systematic approach to profile indigenous microbes and their metabolites that define the sensory signature of fermented foods and beverages.
Technical
The method combines cold‑preserved sampling, 16S rRNA gene sequencing, and untargeted metabolomics to map microbial community structure and volatile phenolic production. PCR amplification (94 °C 30 s, 55 °C 30 s, 72 °C 45 s, 30 cycles) and LC‑MS analysis at 25–30 °C for 48–72 h capture the biochemical fingerprints that link specific taxa to flavor compounds. Controlled fermentation trials at product‑specific temperatures (wine 18–22 °C, cheese 8–12 °C, coffee 30–35 °C) validate causal relationships.
Science
Primary Reaction
Microbial catabolism of sugars and amino acids yielding volatile phenolics, esters, and alcohols that contribute to terroir‑specific aroma.
