When extracting CBD oil, the extraction method is one of the most important things we need to consider. These processes can yield variable results. Some of them can be really disastrous, while others can provide pure, untainted CBD oil.
Keep in mind that the cannabis plant is very complex. It has numerous substances such as terpenes, flavonoids, and cannabinoids. By using CBD extraction or THC extraction, you can target just the right chemicals that you want to remove. Unfortunately, this isn’t always an easy task. Depending on desired results, you can focus on a specific procedure.
Among others, you can utilize alcohol extraction by using products from the Simple Solvents store. In this article, we will talk about certain cannabis extraction methods and how to best utilize them. Check it out!
Choosing the right hemp extraction and refinement method
While many companies mention CO2 extraction as the best process, this method is not always ideal. The optimal procedure will depend on your goals and, specifically, the end-product you want to create.
Finding the right process can be a bit overwhelming. This is especially true when we consider the fact that some of the equipment for these procedures can be really expensive.
So, the best way to go about things is to perform the right market research beforehand. By determining what kind of cannabis products you want to create, it becomes much easier to find a suitable extraction procedure.
Let’s review the two best ways of cannabis extraction: Solvent extraction and CO2 extraction.
As the name implies, during solvent extraction, you will use a solvent to perform the procedure. Companies love this method as it is efficient, relatively cheap, and easy to scale. If you know how to do it properly and safely, it might be the best procedure for your company. Keep in mind that you'll still have to do it in accordance with US laws.
Most commonly, ethanol will be used for the process. It is a colorless liquid that requires extra attention due to its volatility. We've used ethanol for thousands of years as an extraction agent, and it still remains one of the most popular methods of getting oils.
The great thing about this substance is that it's really versatile. You can get all the necessary chemicals from the hemp plant without causing any damage to them (that is if you know how to properly perform the process).
How does ethanol extraction work?
During ethanol extraction, a company will target specific compounds that they want to extract from the rest. Usually, these are terpenes and cannabinoids such as CBD and THC.
All of these chemicals are fat-soluble, which is great because ethanol is also fat-soluble. In other words, when you want to extract full-spectrum CBD oil, using ethanol will provide some advantages.
It is very important for ethanol to be cold during the procedure. This will increase its affinity toward fat-soluble, making it that much more efficient. If you do the process at room temperature, this will extract not only cannabinoids but various terpenes that you don’t necessarily need.
While ethanol is pretty awesome for cannabis extraction, it does have a few flaws. For example, if you just want to focus on CBD extraction or THC extraction, this might not be an ideal process. The procedure is not ideal for isolating specific chemicals.
What are the benefits of ethanol extraction?
Ethanol provides optimal results when you wish to go with higher volumes. This makes it great for companies that are extracting enormous quantities of substance on a daily basis. It is also a very safe process compared to some other methods. Ethanol is versatile and easy to use.
Among others, this solvent will allow you to dissolve almost all polar and non-polar chemicals. As mentioned, cold temperature makes it even more efficient.
What's even better is that the substance can easily be stored. If you have the right AHJ storage permit, you can keep this chemical on your premises without ever encountering any issues.
Lastly, ethanol allows you to eliminate winterization and dewaxing. According to the Simple Solvents team, this is the ideal process for getting full-spectrum CBD oil.
One of the two most popular extraction methods, the CO2 process, utilized highly pressurized carbon dioxide. The substance will be able to remove CBD and other cannabinoids from the hemp plant. In a way, CO2 is utilized as a solvent by changing its state into a liquid one.
By utilizing CO2 extraction, you will be able to isolate, preserve, and maintain almost a perfect purity of CBD oil. There will be no plant matter within the end-product, and it will be completely safe for human consumption.
Unfortunately, you will have to invest quite a bit to buy extraction equipment. This can pose a really big burden for new hemp and marijuana enterprises.
How does CO2 extraction work?
During CO2 extraction, CO2 will be changed from its gas form to a liquid. This is done by reducing the temperature to -69 Fahrenheit and below. Furthermore, it is also necessary to increase the pressure.
When CO2 changes its state, the temperature is increased to the point where this new liquid becomes supercritical. In this state, CO2 will have characteristics of both liquid and gas. Now, the company will introduce plant matter.
As the substance goes through this material, it will completely dissolve trichomes and extract terpenes and cannabinoids. Once that’s over, the solution will go through a separator where desirable compounds will be separated from the rest.
What are the benefits of CO2 extraction?
Experts consider CO2 extraction as a very safe procedure for getting cannabinoids and terpenes.
The oil we get from it will be very pure, and there will be no traces of solvent or plant matter. It is also great because it protects fragile cannabinoids and other chemicals found in the cannabis plant.
Another benefit of the process is that you can easily adjust it based on desired results. Lastly, the process is completely environmentally friendly.
