coffee physics

I can forgive the εR-equals-zero-instead-of-unity mistake, but what does that have to do with CO2 release? And the glass-transition temperature? Seriously? Of a coffee bean?
My favorite part is that neither of those two ridiculous statements is cited.
OK, this wins an EDSEL for “Most creatively incorrect physical analysis of food chemistries.”

Grantology. The eventual funded conclusion will be that coffee beans should be treated with the correct amount of supercritical CO2 with careful temperature profiling to (chronically unsuccessfully) create premium beans from dross. Years of tasting panels will be necessary after years of defining a multi-dimensional parametric model. Remember… It is not wrong, it is heteroskedasticity (the golden-armored savior of economics, psychology, climatology, and other grandiloquent lies).
Uncle Al would go with C-13 labeling. Sophisticated mass spec data always lends credibility. A PhD gal in U/Manitoba MSes whole freshly dissected roach brains to model what they are thinking from neurotransmitter and othe molecular ratios. Uncle Al offers a bottom line suggestion: “WHAAAAAA!!!!!”

Alton Brown talks a little bit about CO2 emissions from roasted coffee in this episode of “Good Eats” : http://www.goodeatsfanpage.com/Season2/Coffee/CoffeeTranscript.htm
Alton doesn’t mention it being important to freshness or taste, however, so I’m not sure how important it is to fire up the ol’ transmogrifier to study its release from the “glassy bean matrix.”

Wait, there’s an award for the ‘Most creatively incorrect physical analysis of food chemistries’??
Well, about time.

hey fiona. EDSEL stands for “EveryDayScientist’s Extraordinary Laud” award.

It was cited twice in a separations journal.
*snicker*

ok, guy you got an award for scientific small-mindedness!! why shouldn’t a food product exhibit glass transition? because it is too complicated for you physicians???

i know that food products exhibit a Tg: liquids and emulsions and gels. sure. but a coffee bean?? do you have a reference?

[…] Whoa. I don’t taste any tight blossoms or structure. My labmate suggested that maybe they used Penta Water for the structure. I think that the structure comes from the coffee matrix being below its glass transition temperature. […]
