Key Points

The study aims to identify how subthreshold components contribute to beer aroma and their effects on beer and seafood flavor compatibility.
Gas chromatography-olfactometry was used to analyze Pilsner-type beer aromas.
76 aroma components were identified and quantified against a reconstructed ethanol/water medium.
Sensory evaluation was conducted to examine flavor interactions between beer and dried squid.
Only 9 components above threshold levels were found in the beer.
The reconstructed aroma model could not fully reproduce the complex beer aroma.
Dried squid pairing revealed enhanced metallic notes in beer while suppressing them in sake.
The identified component (Z)-1,5-octadien-3-one was established as a significant factor in flavor changes.
