Which foods contain 6,10,14-trimethylpentadecan-2-one?

We list 13 ingredients that contain it, but presence is not the same as smell. What matters is how much is there compared with how little it takes to notice it. That ratio is the odour activity value (OAV): above 1, you can smell it.

Found in

Measured foods first, then real food profiles, then thin or composite records (marked). The figure beside each is how many compounds that ingredient has in total, not the amount of 6,10,14-trimethylpentadecan-2-one in it. ✓n = sources that recorded the link.

How strong is 6,10,14-trimethylpentadecan-2-one?

We hold no published odour threshold for 6,10,14-trimethylpentadecan-2-one, so we cannot say how little of it you could smell.
