One of the criticisms of super-critical CO2 extraction is that the terpene profile gets depleted by heat during the decarboxylation process. Terpenes are the molecules that endow cannabis with its pungent smell. These aromatic compounds have significant therapeutic attributes. Some product-makers, use various methods to improve and increase terpene content.
Do we even know if Hargett has the equipment for the CO2 extraction process.
On the Innovative Extraction site I found the following:
With our own extraction machine and our patent pending extraction process
But, in doing a patent search I didn't find any patents or patents that have been applied for - if anyone has found these please post them.
