See the chart below for a comprehensive breakdown of products versus processes Primary Extraction: The process of removing the desirable plant Full Spectrum CBD (THC Free): A CBD primary extract containing a full. When CBD oil is ingested, however, only 20% of it is absorbed. This means that for CBD to be effective, the CBD extraction process must be. CBD (Cannabidiol) is a compound that has shown promise in a variety of medical applications, from pain relief to relieving anxiety, and many other ailments in.

To achieve cannabis in concentrate form, the cannabinoids of the plant must be extracted and condensed into as pure a form as possible. A number of different ways can be used to isolate the valuable cannabinoids found in the cannabis plant. Extraction methods that involve solvents are very popular and provide a quality product, but require professional equipment and knowledge to get right. Solventless methods are simple, natural but do not offer the same THC and cannabinoid percentages.
Some methods are superior and provide better taste, enhanced terpene retention and a pure product. Dry-sieve extraction typically involves taking dried cannabis plants and beating or shaking them against a mesh screen so that the trichome crystals fall off and can be collected. Water extraction, also known as water hash or bubble hash is made by adding cannabis plants to a set of sieve-like bags submerged in freezing cold water and stirred. The cold and stirring causes the trichomes to fall off the plant and pass through a progressively tighter series of collection screens.
The result is a kief or hashish that can be dabbed or smoked and provides THC levels from 50 to 70 percent. Rosin is a cannabis concentrate that has a buttery or shatter-like consistency and is produced without using additives or solvents to extract the trichomes from the plant material. Instead, heat and pressure are used to extract the trichome rich resin that contains the beneficial ingredients of the cannabis plant.
Referred to as an ISO Wash, this extraction method involves taking dried cannabis flower and soaking it briefly in isopropyl alcohol. Once soaking, the mixture of ISO and flower is shaken gently and then strained into a separate dish. The isopropyl alcohol works to strip the trichomes from the plant material into the solvent.
The concentrated liquid then has any remaining solvent evaporated in a vacuum oven at under degree Fahrenheit until a potent THC rich oil remains. ISO wash extract is typically filled with cannabinoids but also contains some chlorophyll, waxes and plant alkaloids. The longer the soak, the more plant material will also be extracted, an undesirable side effect of this extraction method.
Butane extraction has been made famous in the food and perfume industries but has since been repurposed for cannabis extraction due to its powerful potency and excellent terpene retention. To perform a BHO extraction, a vessel or column is filled with cannabis, and a filter attached at one end. Cans of butane are sprayed through the cannabis to extract the cannabinoids, and the cannabinoid-rich butane is collected in another vessel.
The solvent and cannabinoid mix is then left to evaporate or is purged in a vacuum oven. BHO extraction can be very dangerous if not done correctly as the butane gas being used is extremely flammable. A vacuum oven works to purge the solvent residue from the oil and leaves behind a golden coloured oil that typically measures around 80 percent THC.
This method is popular for producing many types of shatter, waxes, crumbles, and oils. Another famous extraction method, Supercritical CO2 extraction is a great way to get all those amazing cannabinoids separated from the cannabis plant material. Some of our Metrc extract testing is available above under the testing tab and individual tests are supplied with delivered product.
Our proprietary CO2 extraction process is designed to negate the need for additional processing while retaining some of the industries highest terpene and cannabinoid content. Different extraction methods can benefit people differently. By defining the target components desired we can engineer your optimal product. To obtain a true full-spectrum extract, we utilize closed-loop CO2 extraction.
Our proprietary process retains beneficial plant components that other processes degrade. Click here to learn more! The CO 2 returns to the CO 2 chamber and the cannabis oil is drained from the separator. Ethanol is added to trimmings and mixed for a couple of minutes to allow the ethanol to dissolve extracts from the plant materials.
The ethanol is strained from the trimmings. Simple- This method is pretty straightforward and can even be done at home. Dangerous- Ethanol is extremely flammable. Finely-chopped plant trimmings are mixed with either ice or dry ice.
This step is supposed to help separate extracts from the plant material. Water is added to the ice and trimmings and the entire mixture is strained through a mesh bag. The excess water is drained from the top and the extracts are left to dry until they become powdery. Ice Water Extraction Pros: Inexpensive- Again, no fancy machinery needed! High Yield- If done correctly, this method produces a relatively large amount of plant extract.
Not always practical- This method can be labor intensive and time consuming.
CBD Extraction Methods
In this article, we cover the various methods of extraction used to create CBD oil. Understanding these methods is important because the. Cannabis oil. CBD-rich cannabis oil can safely be extracted using the methods listed here. Compared with reference extraction methods, MAE achieved the highest extraction yields of temperature, and extraction time on the yields of THC (A-C), CBD (D-F), and CBN (G-I). delivered at a flow rate of mL/min.
