Where you'd actually smell it

Odor Activity Value = measured concentration ÷ odor threshold (361000.0 ppb). OAV ≥ 1 = perceptible.

Food	Concentration (ppb)	OAV	Source
black mulberry	142100.0	0.39	Corpus paper
cookie	14300.0	0.04	Corpus paper
tea	21.0	0.00	—
tomato	57.3	0.00	—
beer	10.1	0.00	—
rice	8.0	0.00	—

Concentrations from PubMed Central Open Access papers (free literature corpus, MIT-style licensed). Copper = OAV ≥ 10 (strongly perceptible). Green = OAV ≥ 1 (perceptible).

Thresholds in published tables

Numbers printed in open-access papers, grouped by the medium the table states. Median and full range of the values; “agree” means two or more papers whose middle 80% of values sit within 100×. Not reviewed.

Measured impact first, then profile share

Every ingredient known to contain chlorogenic acid. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of chlorogenic acid in it. Full concentrations are in the OAV table above.
