Technology has led to the emergence of multiple techniques of extracting CBD from hemp. And each method comes with its own benefits and limitations. So, how do you choose the best? Well, this article will delve into the various methods of extracting CBD. Keep reading to learn more!
Carbon Dioxide (CO2) Extraction
This is one of the best methods for extracting CBD. And it’s typically sub-divided into three categories; mid-critical, supercritical, as well as, subcritical. When carbon dioxide is heated and converted to liquid, it often works like a natural solvent that breaks down hemp biomass turning it into CBD.
As compared to sub and mid-critical extractions, the supercritical method is usually more efficient. It delivers higher yields of CBD. But due to the extreme temperatures involved, terpenes and other phytochemicals might end up getting damaged during the process. CO2 acts as a solvent, hence dissolving components contained in the hemp plant via a process called decarboxylation. This method isn’t just safe but it’s also highly effective. The CBD produced through this process is extremely pure. Remember, carbon dioxide is a non-toxic substance so any residue is considered to be safe for human consumption.
Ethanol Solvent Extraction
In this process, ethanol is used to extract CBD from hemp biomass. Remember, ethanol isn’t just effective at extracting terpenes and cannabinoids- it might also extract chlorophyll. But you can always remove unwanted chlorophyll by filtering the extract.
The ethanol solvent works by extracting some of the natural phytochemicals, cannabinoids, as well as, terpenes from the hemp. And this process is referred to as decarboxylation. The end product of this process is decarboxylated CBD crude oil. However, it can be converted into CBD distillate through simple conversion processes.
Ethanol solvent extraction is a convenient way of producing high yield CBD distillate and isolate. But it isn’t suitable for full-spectrum, waxes, or essential oils since it destroys phytochemicals plus terpenes. Even more, it uses simple hemp processing equipment.
Olive Oil Extraction
This method extraction method can be performed at home and in small-scale commercial settings. Of course, there are other types of oils that can be utilized during this process, but olive oil is the most popular option.
The first step of this process involves decarboxylation. It entails heating hemp plants at specific temperatures with the aim of activating certain chemicals. After decarboxylation, the hemp extract is added to olive oil and then heated to high temperatures of up to 212 degrees Fahrenheit. It’s at this point that CBD extraction takes place. This method is both efficient and economical. Plus, it delivers high yields of pure CBD isolate and distillate.
When choosing a CBD extraction method, price is an extremely important factor. And for you to do this, you’ll need to understand the different types of extraction techniques available and how much you’re willing to spend. Above are the top three methods that are commonly utilized for converting hemp into CBD products. Depending on your needs and preferences, you can always choose a convenient CBD extraction method.
