I remembered that a couple of years ago I took some kitchen scraps with me to make a mini-bait pile, because while we have marten, the population density is very low - at the end of the season, when most residents have been caught, they start moving more during spring dispersal, and it's common to see just a single incoming/outgoing set of tracks going more or less in a straight line across the whole trapline area, so anything that keeps them interested in the place is good. Marten trapping is very different here from what it's like in more forested areas.... requires personalized attention to each marten
One week I saw one such set of tracks, a big hybrid male, who ran without stopping past several boxes (apparenly attracted in the lure, but too cautious/not hungry enough to commit). He then came across the little bait pile and while he ignored things like dead pigeons and cooked bones, he found and dug up several scattered pieces of baking paper left from brownies heavily spiced with cardamom pods, and ate each of them completely, leaving just one piece stuck to a chunk of ice. The next check I had him in the nearest box.

I'm thinking it could be several substances that are readily available in pure chemical form worth investigating here. I'll name three:
cardamom aldehyde, giving cardamom most its smell;
caramel furanone, which is a very tasty, sweet-smelling substance that occurs naturally in many foods and baked sweet things in particular because it's a product of the Maillard reaction;
and Filbert pyrazine, which smells like burnt milk and all roasted/baked foods at once, and is also a super-common natural product of the Maillard reaction. In nature, these substances form as products of ripening and decay (not necessarily rotting) of foods with high nutritional value (with lots of proteins AND sugars) so they must have plenty of signal value to many animals.
Burnt protein smell seems to be attractive to marten/sable, sable trappers use burnt moose skin chunks and feathers a lot and claim it's far more attractive than raw skin/feathers.
