What does 4-methyl-2-(2-methylprop-1-enyl)oxane smell like?

Sources describe it as green, fruity, woody.

It is a key food odorant (individualist): identified in the meta-analysis of 227 food samples as one of 151 individualist odorants, which appear in under 5% of foods and carry the signature of specific ingredients. Source: Dunkel et al. 2014, Angew. Chem. Int. Ed. 53, 7124–7143

Which foods contain 4-methyl-2-(2-methylprop-1-enyl)oxane?

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.
