Too few ingredients to say what it travels with.

What does 2-pentanol acetate smell like?

We hold no odour description for 2-pentanol acetate.

Which foods contain 2-pentanol acetate?

We list 1 ingredient 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 2-pentanol acetate in it. ✓n = sources that recorded the link.

How strong is 2-pentanol acetate?

In a food matrix: 15.0 ppb, from 1 published value.

Published thresholds

1 measured value from the literature, grouped by what was measured: a threshold smelled in clean water, tasted, or measured in a real food are different quantities and are not pooled.
