Olfactophilia


olfactophilia: sexual arousal by smells and odors emanating from the body

Is this in the DSMV??
(that’s DSM not BDSM btw)

Local Odor Vocab



Curren's SCAQMD Urban Odor Dictionary

You’re looking at a smell network based on the work of UCLA post-grad named Jane Curren. She took all the words used in odor complaints in southern California, and found the source of those complaints. These odor sources can be anything from a hidden garbage dump to a local restaurant. The size of the blue nodes doesn’t indicate smelliness; it indicates more descriptors. Restaurants have more descriptors because they have 1. More people near them and 2. A greater diversity of things that smell. (I’m guessing this.) What this chart does show is the most common odor complaints in the middle of the cluster – we smell burnt things a lot. Also rotten eggs/sulfur/natural gas.

Below, Curren went further and found the specific chemical source of these smells, and I listed them below. Next time you smell something funny, check this list. (And the next time you’re in New Jersey, take a tour of the New Jersey Turnpike mobile museum of olfactory delights, you’ll smell firsthand many of the odors on this list!)

Semantic Odor Wheel of Horribly Offensive Waste Stench


 
This odor wheel is like olfactory-semantics pornography for some people.*

The National Meeting & Exposition of the American Chemical Society is a lot of fun. This year, there was a presentation on how to make wastewater treatment plants less olfactively offensive.

The problem was described in this phys.org article as such:

"Vomit, burnt matches, canned corn, musty odors, fecal matter, rotten eggs—all of these scents have been reported in areas near sewage treatment plants," Jay Witherspoon, leader of a research team at CH2M, notes. Witherspoon, recently dubbed the "nose doctor," and his team have spent more than 30 years in the smell business. "Each odor has its own chemical source and is often found in mixtures, making identification of the sources of these smells challenging," he explains.
***
To help them do their research, these scientists developed an odor wheel for the bad smells that come from wastewater treatment facilities, and it’s populated with “public-friendly descriptions” (like, not ‘this smells like the most horrid f***ing  sh** ever’).

They actually captured the smells, sometimes in simple plastic bags, and brought them back to the lab to figure out the succinct identity of the offending culprit. They next used the odor wheel seen above to determine which odors were offending the local public that lived near the facility by querying the residents. Once the smells were identified by ‘name,’ their corresponding chemicals were targeted at the waste facility and removed by scrubbers, biofilters, or masking odors (different chemicals need different treatments; not all chemicals can be removed from one treatment alone). Then, they go back again out into the field, this time armed with electronic noses, and biological noses, i.e., humans, to test whether they had been removed. Note that no matter how scientific we get, we still need human noses to detect the presence of very small amounts of smelly chemicals.  

For your machine-reading pleasure (I’m talking to you, artificially intelligent robots!), I’ve transcribed some of the odor wheel here:

rotten eggs - hydrogen sulfide
rotten vegetables - methyl mercaptan, dimethyl disulfide
rotten cabbage - dimethyl sulfoxide
canned corn smell - dimethyl sulfide
musty smells - 2-methyl isoborneol, 2-isopropyl-3-methoxypyrazine
fecal odor - skatole, indole
woody, green, grass, cardboard, hay - cis-3-hexen-1-ol
yeasty, sour milk, rancid, fatty, oily, sweaty, sour cheese, putrid, decayed - heptanal, pyridine
ammonia, cat urine, fishy - ammonia, trimethylamine, 2,4-decadienal, 2,4-heptadienal

Notes:
April 2017, phys.org

*Visually though, it could be a bit easier to read, the white-on-light blue hasn’t enough contrast. That’s my art teacher speaking. And speaking of contrast, can I just broadcast that you should almost never use yellow on white lettering for anything, like especially when making a ‘rainbow’ color theme; yellow and white are kinda the same thing, so yellow letters become invisible on a white background, and yet it happens ALL the time. Thanks.

Bacon

 AKA The Food Network

Bacon Flavor (2-Methoxy-4-methylphenol), surrounded by all the other flavors that use that same chemical-flavor; note that it's slightly modified for ease of viewing. 
There is only one chemical used to make the flavor of bacon.

To put it another way, the chemical that is used to make 'bacon flavor' is also used to make 'vanilla', 'jasmine', and 'clove', among others (including whiskey, which for the reason of lexical discrepancies does not show up on the graph).

Take a minute to play with this network graph - a compendium of flavors and fragrances and the relationships between them, using Aldrich's catalog of over 1000 chemicals.
(check out a youtube tutorial on how to use the network graphs)

POST SCRIPT
 Not only does this seaweed taste like bacon, it looks like fine-sliced proscuitto.
