What You Need to Know
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.
The Science
Primary Reaction
Microbial catabolism of sugars and amino acids yielding volatile phenolics, esters, and alcohols that contribute to terroir‑specific aroma.
