I was more imagining a completely pedestrian sourced sample. Those are likely large aggregate pools to minimize heterogeneity. Looking for something like, “Go to corner store, buy 12 pack canned CokeCola (with aspartame), dilute 1:10, measure”
I didn't watch the video, but assuming they used a mass spectrometer, the end result will be identical to the real thing, anyone tasting otherwise is deluding themselves.
The video explains how the gas based mass spectrometers he had (indirect) access to don't normally pick up nonvolatile compounds like tannins. It was a big breakthrough that since he didn't have cocoa leaf extract, and he basically nailed everything else, he couldn't really understand what he was missing until he realised the extract would likely contain tannins.
So there may be other nonvolatile compounds which nevertheless impact the flavour profile. While a lot of flavour is in your nose, not all of it is...
Have you ever seen that triangular chart comparing concentrations, impurities , etc? It's generally presented on log scales and very effectively demonstrates the often enormous number of trace-level compounds in otherwise substances deemed pure. It's the absolute pinnacle when it comes to teaching chem students about purity.
No doubt you're correct but it only takes one compound in trace amounts whose odor can be detected in parts per million to throw out a seemingly identical comparison done with spectroscopy.
Right, calibration is everything but sometimes that's damn hard to achieve. Also, here we're dealing with natural substances (at least some are like cola leaves). It's not hard to imagine there'd be thousands of organic molecules involved albeit most of them in minute amounts.
Someone once said the reason we had alcohol before civilization is that we carry around a chemical testing laboratory in our faces.
It just so happens that everything in beer that can go wrong and hurt you (any sooner than cancer) creates a distinct aftertaste and you can learn to avoid it rather easily.
The only exception of course is if you use poisonous ingredients in the first place.
Weird to mention FDM prints when people, including the author's examples, generally use resin prints which don't have any of the artifacts that you get from FDM prints.
I had a similar issue with "ant", except it was horizontal and the game refused to acknowledge I had found it. I'm wondering if it only registers the ones that it initially generates and doesn't double check when you select others or something. I did notice when you move it, it updated the list to reflect that there were two aardvark's so I'm not sure why it didn't recognize the 'ant' that I located.
