To extract CBD-rich cannabis oil, one must start with CBD-rich plant material. There are many ways to extract oil from the cannabis plant, each has its pros and . To isolate the individual compounds (CBD being one of them), the extracted oil needs to be distilled after extraction. The first step is a process called. 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.
Extraction: CBD Oil
The first step to creating any of the CBD products available on the market today is to create an oil extract. This oil can be extracted from cannabis plants including marijuana and hemp.
In this article, we cover the various methods of extraction used to create CBD oil. Understanding these methods is important because the resulting oils are not all the same.
Today, hemp is the primary source of CBD oil extraction. A number of states jumped at the chance and have allowed hemp farming within their borders. This 'industrial hemp' is a form of cannabis which contains no more than 0. When extracting CBD oil, the quality of a hemp source is extremely important.
Currently, hemp is not a USDA certified organic product. That being said, there are growers out there adhering to the same standards.
You'll also want to be sure that your oil is being extracted from the whole hemp plant, not just the seeds and stalks. The seeds and stalks of the plant contain minimal amounts of cannabinoids and are not adequate for use when creating CBD oil. Next, we are going to discuss the various processes used to extract oil from the plant material. CO 2 extraction is the best method used to create CBD oil. The 'supercritical' or 'subcritical' extraction method puts carbon dioxide under high pressure while maintaining a low temperature.
The resulting extract a highly concentrated, totally pure oil extract. This process requires expensive equipment and experienced operators. Because of this, the resulting oil is often higher priced for the end consumer, but of a higher quality. A supercritical extracted oil will be an amber color similar to honey in appearance. If you're searching for a CBD product, we always recommend something that began as a CO 2 extracted oil. Before the rise of popularity of CBD oil use, a Canadian man named Rick Simpson extracted an oil from marijuana to heal his own skin cancer.
This extraction method uses an alcohol solvent - most commonly ethanol. It is commonly used as a food preservative and additive found in many products at the grocery store.
Using ethanol as a solvent is more efficient than CO 2 extraction, but comes with some downsides. Ethanol is a polar solvent which means it will mix with water and dissolve water-soluble molecules. 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.
One of the most popular industrial hemp strains is Fedora 17 because it has an extremely low THC content which means that any CBD extracted from it has virtually no psychoactive effects. CBD oil made from hemp is legal in almost every country around the world including in all 50 states in the U. In fact, it is the most regularly used extraction method of all because it is safe and provides a pure end product.
CO2 acts like a solvent at certain temperatures and pressures but possesses none of the dangers. While it is safe and effective, it also involves extremely expensive equipment. The rather sophisticated machines used for the purpose work to freeze the CO2 gas and compress it into a supercritical cold liquid state. At this stage, you have your starting point for CO2 Cannabis extraction. Effectively, the supercritical CO2 is capable of filling a container like gas while also maintaining density like a liquid.
Regarding extracting the CBD oil using this technique, you simply begin with liquid CO2 and raise its pressure via a compressor. You must also raise its temperature using a heater. The next step involves passing the supercritical carbon dioxide through some high-quality cannabis which should be in an extractor. Now, the CO2 will pull the essential trichomes and terpene oils out of the plant.
The solution gets passed via a separator and broken down into its requisite parts. The good stuff including trichomes and terpene is sent to the collection container. Meanwhile, the supercritical CO2 goes through a condenser and turned back into a liquid. Finally, the liquid goes to a special storage tank and can be used to begin the process all over again. This form of extraction involves low temperature and low pressure. Subcritical extractions take longer than their supercritical counterpart and also produce a smaller yield.
Subcritical extraction is less likely to damage terpenes. Mid-critical is simply a general range between subcritical and supercritical. Some companies combine supercritical and subcritical to create a full-spectrum CO2 cannabis extract. They use the subcritical extraction method to separate the drawn out oil and draw out the very same plant material using supercritical pressure.
The oils are then homogenized into one which creates a unanimated oil. While other liquids such as ethanol can be used in this process, olive oil is the most commonly used substance for this extraction which can be performed at home. The first step involves ensuring the raw plant material is decarboxylated. Most experts recommend heating at degrees Fahrenheit for 60 minutes or at degrees Fahrenheit for 30 minutes. Once this step is completed, add the plant material to the olive oil and heat to degrees Fahrenheit for up to 2 hours and at least 1 hour.
This process should result in the extraction of the cannabinoids, and ultimately, you should receive oil with the CBD content you require. The dry ice extraction method is another method of CBD extraction that can be performed at home although it takes a bit more time and effort than its olive oil equivalent. Put on your gloves and eye protection, chop up the cannabis plant into small pieces and place it in the bucket. Cover the plant with the dry ice and leave it for 3 minutes; it is best only to fill the bucket halfway; this process causes the freezing of the trichome resins.
Turn the bucket upside down on the Plexiglas and shake as much resin through the mesh bag as possible. Scrap the hash off the Plexiglas with your scraper and place it into one of the jars. Ethanol, low-grade alcohol, and butane are among the most common substances used in Solvent Extraction. Although ethanol extracts the full range of cannabinoids and terpenes from the plant which makes the end product safe for consumption, it also extracts chlorophyll which may lead to some unpleasant side effects.
Butane offers a stronger oil than ethanol, but it is more likely to contain solvents which could irritate the lungs. All you have to do is add the liquid whether it is butane, alcohol or ethanol to the plant material. The extraction liquid will strip away the cannabinoids and flavor from the plant material but will probably take some of the green colorings too.
Once you believe you have enough cannabinoids in liquid form, heat the liquid to evaporate it down to the CBD base oil. It is extremely important to understand the various CBD extraction methods as they have a major impact on the quality of the end product; not to mention your health.
The cost of CO2 supercritical extraction means it is not possible for Those who create their own CBD oils will tend to use dry ice or olive oil, which provide great purity, yield and are easy to do. There are also other extraction methods that we have not mentioned in this guide.

If you want to check us out you can see here. Since chlorophyll is water soluble, and the essence your after, is not. Use hot water to rinse and squeeze the material and repeat. Then the solvent process will yield a higher quality of product.
I would think ethyl ether would be even better, however way more volatile of a solvent. In any event, any reaction using ethyl ether should only be carried out by knowledgeable and qualified personnel.
If you thought butane was flammable, step aside cupcake, ether is extremely volatile. Also, keep in mind there is water in acetone too! Water is the most abundant solvent on earth, given time, it will break down anything. Why are you calling chlorophyll harmful?
It actually enhances bioavilability and has other health benefits. Chlorophyll is very easy to remove from any extraction as well.
The Complete Guide to CBD Extractions (CO2 Cannabis Extraction, Olive Oil and Solvents)
Several common forms of cannabis extraction rely on a solvent, such as To really make shatter, which is a hard version of butane hash oil. CBD enthusiasts more often use the olive oil extraction process rather than commercial CBD producers. CBD Oil or Hemp Extract- CBD Oil, often times referred to as Hemp Extract. Hemp extract is an extract with naturally occurring terpenes.
