Published thresholds

1 measured value from the literature. Grouped by what was actually measured — a threshold smelled in clean water, tasted in the mouth, or measured in a real food are three different quantities and are not pooled.

In a food matrix

577 ppb

Measured in a real food, where the matrix shifts detection — not a clean-water value.

Threshold	Matrix	Source	Paper
577 ppb	water (food: unknown)	Literature corpus	29444125, 35056794

Only values we can attribute are listed. Where a compendium's licence does not permit public attribution its figures are omitted here, so every number on this page traces to a citable source.

Where you'd actually smell it

Odor Activity Value = measured concentration ÷ odor threshold (577.067945 ppb, the engine's canonical value — see the 1 published values). OAV ≥ 1 = perceptible.

Measured impact first, then profile share

Every ingredient known to contain procyanidin b1. 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 procyanidin b1 in it. Full concentrations are in the OAV table above.
