Most CBD consumers understand that, as with most things, not all CBD oils and extracts are the same. As people are growing more interested in using CBD, they are also becoming more interested in CBD extraction, meaning where the CBD comes from, how it’s made and what categorizes it as a high-quality CBD product.
The answers to many of these questions can be found in how the CBD gets from the plant into the product. The specific extraction processes used, how it is purified and how all of these factors come together contribute to the type of CBD oil that is produced.
For CBD to get out of the plant and into the CBD oil, the raw hemp plant needs to go through a couple of processes. The first step is the different plant compounds, including CBD, need to be extracted into what is called a raw or crude CBD oil. Next, the raw oil needs to be purified and then, depending on what you want the final product to be, the full extraction process is completed.
In this post, we are going to explain the different extraction methods and the pros and cons of each. We’ll also break down the different types of CBD oil and extracts that are most commonly available on the market right now.
How CBD is extracted can be either very simple or very complicated. For instance, herbalists have been making CBD oils and tinctures for thousands of years by simply warming bits of hemp with an oil or fat and steeping it for a couple of days. In contrast, large-scale extractors and manufacturers use highly complex processes that need expensive products and equipment.
To simplify things, we’re going to discuss the two types of CBD extraction you are most likely to come across.
CO2 extraction comes in two forms, supercritical and subcritical. While each of these forms are subtly different from the other, the process is very similar. This extraction method relies on the special characteristic of carbon dioxide (CO2) to exist in either a gas, liquid or solid state depending on the temperature and the amount of pressure it is under. Using a machine called a closed-loop extractor, the different compounds in the hemp plant are extracted by squeezing the hemp material at varying temperatures and pressures to extract the different cannabinoids, terpenes and other compounds.
Since this extraction process uses cold temperatures and pressure to extract the different hemp compounds from the plant, CO2 extraction can accurately and selectively isolate all the different cannabinoids and terpenes. Additionally, because this process doesn’t use solvents of heat, many of the more sensitive molecules are conserved. This creates a richer end product and is considered by many as the highest-quality, full-spectrum CBD extracts.
Because the process is so complicated and time consuming, it requires a lot of specialized equipment and expertise, making it a very expensive process. In addition, CO2 extraction doesn’t yield very much oil, which makes for quite an expensive final product.
The name pretty much says it all! The hemp plant compounds are extracted by using a solvent, usually an alcohol like ethanol or a hydrocarbon, that dissolves the different cannabinoids, terpenes, waxes and oils. This produces a mixture from which the solvent needs to be removed through an evaporation process.
The biggest benefits of solvent extraction are that it doesn’t require any expensive equipment and the extraction staff does not need to be particularly specialized. Unlike CO2 extraction, it is a high yield extraction method that produces a high volume of crude CBD oil. This makes it one of the most popular methods among commercial extraction facilities and commercial producers.
The biggest issue that many people have with solvent extraction methods is that solvent residue can remain in the crude CBD oil, resulting in a low-quality and potential harmful product. Likewise, this type of extraction method can cause many of the good cannabinoids and terpenes to be removed or destroyed during the purification process.
When it comes to solvent extraction, the crude CBD oil needs to go through some further purification processes before it can be used in a CBD oil or some other type of CBD product. The CBD extract can also be processed to produce a single isolate.
The following two are the most common:
Each extraction and post-purification method produces a different type of product. The most popular of these are:
