Thread: Ailments and corresponding cannabinoids

    I can't remember where I got this from, but here it is anyways.

    Decarboxylation of cannabinoid acids is a function of time and temperature, thus at higher temperatures a shorter period of time will be taken for complete decarboxylation of a given amount of cannabinoid acid. In selecting appropriate conditions for decarboxylation consideration must, however, be given to minimizing thermal degradation of the desirable, pharmacological cannabinoids into undesirable degradation products, particularly thermal degradation of THC to cannabinol (CBN).

    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.

    Preferably the first step is conducted at a temperature in the range of 212 F. to 230 F. for 10-20 minutes. More preferably the first temperature is about 221 F. and the first time period is about 15 minutes.

    If the plant material is derived from cannabis plants having a high CBD content (defined as >90% CBD as a percentage of total cannabinoid content), the second temperature is preferably in the range from 239 F. to 257 F., preferably about 248 F. and the second time period is in the range from 45 to 75 minutes, preferably about 60 minutes. More preferably the second temperature is in the range from 275 F. to 293 F., preferably 284 F. and the second time period is in the range from 15 to 45 minutes, preferably about 30 minutes

    If the plant material is derived from cannabis plants having a high THC content (defined as >90% THC as a percentage of total cannabinoid content), the second temperature is preferably in the range of 239 F. to 257 F., typically 248 F., and the second time period is preferably in the range of 45 minutes to 75 minutes, typically about 60 minutes. More preferably the second temperature is in the range of 210 F. to 230 F., typically 221 F., and the second time period is in the range of 60 to 120 minutes.

    Most preferably the decarboxylation step is conducted at temperatures and for times which ensure at least 97% conversion of the acid cannabinoids to their neutral form, whilst ensuring thermal degradation of THC to CBN is less than 5%.

    I agree. A good chart of base temps to formulate a plan from. Experiment and better if the results are tested in a Lab. This would confirm the findings. Find what works and this chart would help one do that. Great information gang! Education is the key.

    Nice post CgOrganic! Great information there. Specially for all the cookers and bakers Oh and some RSO makers too
