In recent years, CBD has become popular all over the world. CBD is one of the 113 cannabinoids found in the hemp plant and is used by millions of people for treating several health disorders. The CBD present in the CBD products is mainly extracted from the hemp plant even though it is also present in the marijuana plant.
A lot of manufacturers are making CBD products and they use several extraction methods for the extraction of CBD from the hemp plant. You need to extract CBD for separating it and make a concentrated form of it which is easily consumable.
Common CBD Extraction Methods
There are several extraction methods of CBD and each method varies by their end products. Here are the three most common extraction methods of CBD that manufacturers mainly use.
Olive Oil Extraction
This is one of the oldest CBD extraction methods and is also one of the cheapest methods. This extraction process begins with the decarboxylation of raw plant materials. That means the plant material is heated to a particular temperature for a specific time.
The heat makes the cannabinoids in the plant to activate. Then it is added with olive oil and heated again. In this stage, cannabinoids are extracted from the plant. However, olive oil is not evaporated which means the resulting extract will not be much concentrated.
This is the most expensive extraction method of CBD, but yet to be used by many CBD manufacturers because it is the most expensive way of extracting CBD from the hemp plant. CO2 extraction ensures high-quality CBD products. The machine used for the CO2 extraction has three chambers; the first one for holding pressurized CO2, the second one for holding the plant material, and the third one for collecting the end product.
During the process, the CO2 will be pumped from the first chamber to the second chamber. The CO2 will run through the plant material and separate the cannabinoids. In the third chamber, the CO2 is evaporated and leaves the CBD extract at the bottom of the chamber.
This method of CBD extraction uses solvents like butane, ethanol, isopropyl alcohol, propane, etc. for the extraction of CBD from the plant material. Solvent extraction is a faster method to extract CBD but is also one of the dangerous methods.
The extraction process is almost similar to CO2 extraction, the difference is that a solvent is used for separating the cannabinoids from the plant material instead of CO2. The disadvantage of the method is that the solvent residue may not be completely evaporated from the resulting extract.
