To isolate the individual compounds (CBD being one of them), the extracted oil needs to be Hemp and Cannabis Oil Extraction Processes and Techniques. CO2 extraction is gaining popularity for extracting quality CBD oil, but that is only one extraction method. Here you'll find everything you need to know about. Safe and effective ways to extract and produce CBD-rich cannabis oil. To extract CBD-rich cannabis oil, one must start with CBD-rich plant material. High-grade grain alcohol can be used to create high-quality cannabis oil appropriate for vape pen cartridges and other products.
extraction techniques cbd
Chlorophyll is one of the compounds that ethanol will co-extract along with the cannabinoid filled oil. The result is a dark colored oil with a bitter and grassy flavor. The chlorophyll can be removed from the oil using a filtering method, but the process also removes some of the cannabinoids resulting in a lower quality CBD oil product.
This early extraction method was created using a light hydrocarbon solvent like to extract cannabis oil. These hydrocarbons have a low boiling point and can be easily used to extract CBD oil. This cheap and easy method of extraction comes with a variety of issues that make it non-ideal. The resulting oil usually contains a lower concentration of terpenes and cannabinoids like CBD and a higher concentration of THC. This extraction method proved to be both dangerous an inefficient.
This method of extraction is rarely used by commercial CBD companies today. One of the lesser used extraction methods is called lipid extraction. Often organic coconut oil is ued in this extraction process.
Lipid extraction does not require the use of any harsh solvents or CO2. After a CBD extract is created, there are some additional steps that are performed to get the product ready for consumption. The naturally occurring cannabinoids found on the cannabis plant come in an acid form.
For example, the following common acid forms of cannabinoids found in CBD products are:. When a low temperature method like supercritical CO2 extraction is used, the original acid forms of the cannabinoids is preserved. In order to activate these cannabinoids and removed the acid molecule, the CBD extract undergoes a process called decarboxylation. Though this process sounds fancy, it is simply the heating of an extract. The result is the extract becomes what the industry refers to as 'activated'.
These molecules interact with the body differently than the 'activated' or non-acid forms of these same substances. Limited research and anecdotal user experiences point to these raw cannabinoid forms providing some unique health benefits. This is driving some companies to include the acid forms of these cannabinoids in addition to the activated non-acid forms.
When an extract is created from cannabis, there are a wide range of fatty acids, plant materials, chlorophyll, cannabinoids, and terpenoids contained in the extract. There is an optional process called winterization which works to further purify the extract. The process of winterizing consists of soaking the CBD extract in alcohol and freezing it in order to separate the waxes, lipids, and residual solvents.
The end result is a more concentrated extract in terms of cannabinoids. This process is not always desired because through this process some of the terpenes are also removed from the extract. This can have a negative outcome on the entourage effect. Now that you understand CBD extraction, its time to take things a step further. Today you'll commonly find single-molecule CBD isolates. All other cannabinoids, terpenes, plant materials, oil, and chlorophyll is removed in the creation of this powder.
All that is left is naturally sourced CBD crystals that carry no odor or flavor. This isolate is made by first extracting oil using one of the methods we discussed above.
Next, chemists use a process known as chromatography to remove plant materials and other cannabinoids. This isolate is often desired because it can be dissolved in liquid, added to food products, tinctures and more. The isolate is also beneficial because it is clearly defined as legal under the Drug Code for Marijuana Extract. Learn more about these isolates in our article: As a consumer, you should understand that while isolate products are versatile, they are not as effective as an oil containing a full-spectrum cannabinoid profile.
The single-cannabinoid CBD is less effective than a full-spectrum product due to the entourage effect. 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. Olive Oil Extraction This technique results in cannabis-infused oil, not pure cannabis extract. Cannabis plant trimmings are placed in olive oil or any other cooking oil and warmed for hours.
The infused oil is strained from the plant trimmings. Olive Oil Extraction Pros: Easy- This is by far the easiest extraction method and is a popular home option. Olive Oil Extraction Cons:
