[0039]
Preferably, decarboxylation is carried out in a multi-step heating process in which the plant material is:
i) heated to a first temperature for a first (relatively short) time period to evaporate off retained water and allow for uniform heating of the plant material; and
ii) the temperature is increased to a second temperature for a second time period (typically longer than the first time period) until at least 95% conversion of the acid cannabinoids to their neutral form has occurred.
Just CTRL+F [0039] or "Decarboxylation" and go from there.
