![]() ![]() Why extracting terpenes with traditional methods is so difficultįor all their advantages, these common extraction methods have one major drawback: terpenes are often destroyed in the process. The butane is then removed from the resulting mixture with heat. ![]() Not unlike the CO2 extraction method, butane is passed over plant material to dissolve terpenes, cannabinoids, and other compounds. Used to create both THC-dominant and CBD-dominant concentrate products, butane extracts and separates the psychoactive properties of cannabis into an oily or waxy substance. Butane hash oil (BHO) or other extracts liked “shatter,” “crumble,” “wax,” or “budder” are all results of the butane extraction process. Since the CO2 naturally evaporates from the final product, it makes this method among the cleanest and safest for consumption. Though it takes longer and yields a smaller quantity, subcritical extraction is easier on the plant material.Both CO2 extraction methods require specialized equipment to do it safely, efficiently, and reliably. Since no heat is used in the process, more terpenes and cannabinoids make it to the final product. Subcritical extraction, however, uses lower temperatures and less pressure to achieve similar results. That solution is then collected, cooled and processed into the final product. ![]() While in this state, it passes over ground plant material, dissolving trichomes, terpenes, cannabinoids, and other desired compounds into a liquid. Because CO2 can easily fluctuate between its gaseous and liquid states, there are two different ways to use it for extraction: supercritical fluid extraction and subcritical fluid extraction.In supercritical fluid extraction, CO2 is heated and pressurized to a point where it exhibits gas and liquid properties. This non-toxic method utilizes carbon dioxide (CO2) as the separating agent. It should be noted that the hot alcohol extraction method relies on the Soxhlet extraction technique, which requires a special extractor to complete. The difference in temperature alters how much of the plant’s phytocannabinoids and terpenes will remain in the final product. Once complete, the resulting solution is refined to remove residual solvent. This is done largely by soaking the cannabis in either hot, cold, or room temperature ethanol to extract the plant’s phytocannabinoid content. ![]() Considered one of the lowest cost and most efficient methods of extraction, ethanol extraction lets producers turn large amounts of plant material into a potent cannabis oil . The following three methods are generally considered some of the most common methods of cannabinoid extraction: In other cases, individual phytocannabinoids like CBD are extracted, isolated, and used to make phytocannabinoid specific products. Oftentimes, cannabis extraction producers attempt to create a final product that’s indicative of the source material. With cannabis, manufacturers are most interested in phytocannabinoids (both major ones like THC and CBD, and minor cannabinoids like CBC and THC-V) and the fragile and aromatic terpenes. The goal of cannabis extraction is to pull out the more desirable compounds in the flower and use them in other products. What are the most common cannabis extraction methods? How are these innovations changing how the cannabis industry makes concentrates, edibles, vape cartridges, topicals, and other products? Here are some cannabis extraction technologies you should know about – and how Cryo Cure is contributing to the conversation. and the globe, however, emerging technologies are simplifying the process, preserving sensitive terpene content, and capturing more overall phytocannabinoid content. As the cannabis industry expands across the U.S. Cannabis extraction makes it possible to create new and innovative products, but it’s a process that has remained relatively unchanged for decades. ![]()
