The Peres enose sensor which is currently in beta phase and had a campaign on Indiegogo last year. Once it is ready for sale it says it will be able to detect Volatile Organic Compounds associated with rotting meat. The beta version was $89 and I think the final version should be around $150, which is affordable. It seems to be a Lithuanian company based in the UK.
What use is this to the metabolic malodor community ?
It would seem likely that some of the VOCs that the Peres enose will detect will be VOCs that people with metabolic malodors may emit. So far I have been unable to find a list of what VOCs it tests for or for what levels. Although I think it will be of some use, I currently presume it will not currently be an 'ideal' consumer enose for metabolic malodor, but I would buy one myself as there are currently no other sensors as close to our needs.
My own view :
Most people with 'metabolic malodor' seem to complain of having 'fecal/flatulent' odors and other malodors associated with humans waste. My guess is that most of these are sulfides and amines that should be oxidized/neutralized by FMO3 enzyme. Possibly some of these sulfides and amines are high in rotting meat too, so there may be some crossover benefit of this enose for the 'fecal body odor' sufferer.
Some sulfides I mean would be dimethylsulfide, dimethyldisulfide, hydrogen sulfide, and presumably others. Also of course a Enose sensor for metbolic malodors would include trimethylamine.
So the Peres enose sensor in it's current form may be of some use to the metabolic malodor community until one specifically for the community is developed.
How important is an enose to the metabolic malodor community ?
In my opinion it is one of the essential needs. Most people with metabolic malodor cannot smell themselves (it is my belief this is the case in most/all forms of body odor/halitosis) so it would be an essential medical device.
