#volatiles

Can someone tell me what's the deal with some red peppers which, once they've been open for a few days in the fridge, start to smell like an E. coli agar plate?

And why am I excessively bothered by this but many other people don't notice (or don't care)?

It's just red peppers. Not yellow/orange. Not green. Any only some, not all. (1/3)

Great to be at the #ICOM2 today, great talk by Prof. Thomas Hummel on olfaction now.

Looking forward to presenting my work tomorrow and chairing a session on Volatilomics!

Just got notice that we got funding from the R Consortium to work on a really interesting project! `volcalc` is an R package for calculating estimated volatility of chemicals. Currently only works for compounds in the KEGG database, but we're going to re-factor so it works on any SMILES, InChI, or .mol file representation. I'm super excited to work on this!
