Jaccard

“Reported” counts reflect the compounds characterized for each ingredient across the studies and databases we aggregate — a measure of coverage, not an exhaustive census. Different analyses target different compound classes and methods, so read these as what has been characterized, not the total number of molecules present. Jaccard measures shared coverage, so it rewards overlap rather than highlighting the ratio differences that distinguish two ingredients.

Why they pair: shared-compound network

12 of 239 shared shown

Each molecule in the middle is shared by both ingredients — the chemistry bridging Grapefruit and Plum. Node color is chemical class and node size is perceptual potency (bigger = lower odor threshold, so it drives aroma at smaller amounts); a copper ring marks compounds flagged as key aromas in published GC-O studies. Zoom with the +/− buttons or a pinch, drag the background to pan, drag a node to pin it, click any molecule for its full profile.

Where they differ: aroma character

Profile distance 0.12

The Jaccard above measures overlap; this compares each ingredient’s aroma-family mix side by side — the wider the gap between the two bars, the more that family sets the ingredients apart. Grapefruit reads left, Plum reads right.

Grapefruit ◀ ▶ Plum

Shares are fractions of each ingredient’s labeled compounds (307 of 338 for Grapefruit, 347 of 384 for Plum) — compositional lean, not concentration. Aroma labels come from our compound enrichment and cover most, but not all, characterized molecules.

Pro names the molecules behind each difference — the specific compounds in each aroma family that one ingredient has and the other doesn’t. Sign in to see them.

Shared compounds

239 of 483 total

These are the molecules both ingredients have in common — the chemistry behind why they pair. Grouped by chemical class; ★ marks compounds flagged as key aromas in published GC-O studies.

Most perceptually potent shared compounds

165 of 239 shared are aroma compounds with a measured threshold

Odor threshold is the concentration at which a molecule becomes smellable — lower = more potent. These clear their threshold most easily, so they drive the shared aroma out of proportion to the raw shared count.
