Sorry, you got the wrong guy for "heat" tests! I don't think that it works on anything but 'Sour". From what I've read, it does nothing for "bitter" tastes and I doubt that it effects "hot". They have already isolated the active compounds but found that they could not synthesize it (or get it 'stable' enough) to make it of value to the "Big Guys" corporations. These were the people that did a lot of the early testing in the US. There was another 'private individual' that put millions of dollars into it in the 1960's/70's but there was a very aggressive 'dirty tricks' campaign mounted against him and in the end the US Government pushed through legislation banning it, so he shut down his company laying off 280 workers!
