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 81 shared shown

Each molecule in the middle is shared by both ingredients — the chemistry bridging Chocolate and Walnut. 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 0.24

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. Chocolate reads left, Walnut reads right.

Chocolate ◀ ▶ Walnut

Shares are fractions of each ingredient’s labeled compounds (161 of 177 for Chocolate, 295 of 324 for Walnut) — 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.

Most perceptually potent shared compounds

51 of 81 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.
