In this article, we will learn about the popular CBD extraction methods that are used for the extraction of CBD oil from hemp.
CBD Extraction Methods || How Is CBD Made?
To extract CBD oil, firstly the hemp plant must be rich in CBD concentrations and should have fewer THC concentrations.
Such CBD must also be suitable for human consumption and does not have any major side-effects. There are three most common methods which are used majorly for extracting CBD oil from the hemp plant. Let us discuss these:
Co2 Extraction Method:
This Co2 method can be divided into supercritical, mid critical and subcritical categories. Among these, supercritical is the most common method of Co2 extraction. Since this method is safe and renders a pure product, it is used most regularly.
Under this method of CBD extraction, pressurized carbon dioxide is used to extract CBD from the Hemp plant. Co2 can function as liquid, solid or gas as depending upon the temperature and pressure it is kept under. This method is very safe and effective and is done via extremely expensive equipment called a ‘closed-loop extractor’.
This equipment has three main chambers, the first one holds pressurized Co2 that is dry ice, the second chamber holds the dry plant material, and the third one separates the final product from it. The extracted CBD Oil or the final product is very pure and safe to use. The extracted product is chlorophyll free and has the least risk of contaminants.
Various Benefits of Co2 Extraction Methods:
- Safe: Co2 is safe and has been used by professionals in a number of food products.
- Effective: It is highly effective as it is free of chlorophyll with the least amount of contaminants.
Cons of CO2 Extraction method is it requires extremely expensive equipment and should only be attempted by experienced professionals.
Ethanol Extraction method || Solvent Extraction Method
This extraction method is also referred to as the solvent extraction method. Under this method, ethanol, low-grade alcohol is mostly used to extract CBD oil from hemp. The liquid solvent that is ethanol is run through the plant material to strip away the cannabinoids and flavors from the plant material in the liquid form.
After that, the liquid is heated to evaporate it down and leave only oil. This method is the most simple method and does not require expensive types of equipment to extract CBD oil.
Pros Of Solvent Extraction Method:
- Inexpensive: It is an inexpensive method and does not require any high-costing machinery.
- Simple: It is a straightforward and simple method of extraction and can easily be done at home.
Cons Of Solvent Extraction Method:
- Dangerous: It is a dangerous method as Ethanol is extremely flammable.
- Harmful: This extraction method is harmful as it may produce oil that contains chlorophyll or other harmful contaminants.
Olive oil extraction method:
Many times, olive oil is also used to extract CBD oil from the plant. This method is mostly practiced by home-producers who do not want to indulge in complicated extraction techniques. Under this method, the raw plant is heated for a certain time to activate the chemicals in the plant. Then this plant material is added to olive oil and heated at 100 degree Celsius for around two hours to extract the cannabinoids and the final product will be oil with CBD.
This method is safe as well as quite inexpensive. You can quickly set this up at your home.
Pros of Olive Oil Extraction Method
- Safe: It is an easy and safe option for CBD Extraction.
- Inexpensive: You can easily use this method at home as it requires not a very expensive setup.
Cons Of Olive Oil Extraction method:
- Low Yields: This extraction method produces low concentrations of CBD.
