nastersians

NEMO-Chemistry - 27-2-2018 at 17:06

Anyone got any idea what causes the pepper taste in nastersians? I googled and got conflicting answers.

There is a moth that will only eat the leaves of these, its absolutely tiny and a deep red colour. Ok the caterpillar eats the leaves... but you get my point.

I have only seen a few of them around, i wondered what was in nastersians that made them peppery, i would like to try and experiment with the moth.

I have usually seen this plant name spelled "nasturtium".

What gives them the peppery flavor? Darned if I know, but I can tell you they are milder if you pick them at dawn than at mid day.

Complex little buggers!

(On a second look, I'd bet on ocimene being the peppery one)

Ocimene

My money would be on this

or something like it.

benzyl isothiocyanate?

It's also in mustard.

Hmmm, so its likely not a single compound. That would explain why specifically they choose this plant.

I got zero scientific to say at this point, i asked for a reason and thank you for the links. Its given me something to think about, i have sent off a moth to the natural history museum for ID.

If/when they answer I will explain what is special about this little monster.
