Decarboxylation and Extraction

The acidic cannabinoids are thermally unstable and can undergo decarboxylation when exposed to light or heat via smoking, heating or drying.  In the process usually dried hemp is heated at 230 F, thus converting CBDA to CBD.  Then it go through CO2 extraction device to extract oil.  This is called crude oil at this point.  This oil is winterized to separate unwanted components like fat.
