Do not equate a high dilution factor with a complete causal explanation of the finished aroma. Recombination and omission tests are a further step. Fresh September28: PDF54 appears to confuse dilution steps with FD factors; preparation differs (including concentrated AEDA extract), so raw maxima cannot be interpreted as pure potency ratios.
Chapter3 analytical rationale PDF48 and experiment50–54. Laboratory dilution of a chromatographic sample is not the same as tasting a whiskey at reduced proof.
Dilution-based GC-olfactometry prioritizes odorants that remain detectable at higher dilutions. The resulting factor depends on preparation and detection conditions; in this tequila study, SDA and AEDA differed in missed compounds and maximum dilution factors.
