hello. i know nothing about extraction for cooking. i suggest requesting from cannabis food purveyors, or as you put it- conducting scientific experimentation on your own, and compiling a chart with your air pressure, altitude, and quality strain. i am a total sucker when anyone asks please read, and am voting Ron Paul, so wanted to wish you well. 300* just seems excessive to me. i am thinking higher percentage loss in manufacture. i personally would avoid alcohol or ethanol- to not introduce free hydrocarbons with mutagenetic cancerous characteristics into the cook. i am probably wrong, and another arm will be handy. i just keep the food separate from my intake. i like spreading the flavors on my palate. i get the advantage of simultaneous munchie satisfaction; just like the pleasures that way. perhaps give a class at Berkeley a call, alike a business dude with a product to market, and get them to work on it. i am just a sucker for politeness. enjoy.
