Hemp Extraction Co2

CO2 Extraction

CO2 extraction has been employed for decades, yet COcannabis extraction is relatively new because of prohibition. Therefore, as already mentioned, manufacturers have only recently started perfecting equipment and practices to produce high-quality extracts rather than crude extracts that were labor-intensive to super refine into sellable products. Still, CO2extracts often require further refinement, depending on the end use or desired product purity and potency.

CO2 extraction requires that cannabis material be dry—and the dryer the better. Because of that, the majority of available monoterpenes (myrcene, alpha-Pinene, beta-Pinene, limonene, linalool, terpinolene, just to name a few) are evaporated during the drying process, resulting in a product with a much lower terpene content than the plant material from which it came. That’s not to say all terpenes are eliminated, but most of the terpenes responsible for the full expression of the plant are. This makes it a perfect concentrate for manufacturing edibles, especially those that don’t taste or smell like cannabis, which many consumers and patients prefer.

CO2 extraction is a great method of extracting cannabinoids that can then be super refined via winterization, filtration and distillation. Many extractors employ CO2 as a primary extraction method, then further refine the extract into desired compounds for a variety of uses and products, ranging from edibles to topicals and oil cartridges (often infused with either non-cannabis or cannabis-derived terpenes that are added to the extract). Yields depend on both the percentages of available cannabinoids/terpenes in the plant material being processed and the skill of the technician/operator.
