I see what your sayin now.... I myself have been mulling the same problem, reading through dozens of scholarly articles on essential oils. I have a separate thread on the science of curing in the advanced growing forum on here.
Some cats are doing steam distillation of terps prior to your typical solvent distillation for cannabinoids. I personally haven't tried this but seems interesting enough. Not sure how 230 degree steam is gentler on the terps than other options but who knows.
Problem here is all of our methods involve heat. Whether is vac purging butane or distilling off ethanol. Terps volatilize at room temperature from heat and oxygen so its really a tough problem. I would venture to say that freeze drying fresh nuggets then using those in a vaporizer would be your closest bet to near original oil content. But the point of this thread is vape oil so I'll get back on track.
