Which CBD extraction method is best?
Compared to other methods of producing CBD oil, CO 2 extraction has distinct advantages. First, you can pump supercritical CO 2 through cannabis so that it can selectively absorb cannabinoids and other compounds while leaving everything else behind.
Olive Oil CBD Extraction
First of all, to extract olive oil at home, you need to make sure that the plant material has been decarboxylated. In short, this means that it has undergone the process of activating acidic cannabinoids through heat. Of course, this happens when you smoke or vape, but it can also happen if you put it in the oven.
Supercritical CO 2 CBD extraction
In this method, CO 2 is manipulated into a supercritical state. It has both gas and liquid properties and can be pumped into the plant material under controlled conditions to remove essential terpenes and cannabinoids without damaging them.
Disadvantages of solvent-free extraction
-Low and impractical yields
-No control over purity, minimum level of CBD
-CBD extracts contain plant matter and unwanted cannabinoids
Secondly, because it uses CO2, it can produce CBD oil that is free of chemicals and contaminants. And, after the extraction process is complete, you can reuse the CO2 or release it safely into the atmosphere. Due to the excellent level of control, supercritical CO 2 has become a leading tool extraction method and the one used by Cibdol to produce all its CBD extracts.
Disadvantages of solvent extraction
-Working with solvents can cause injury if not used correctly, they are highly flammable
-Oil can be contaminated with solvents, which are dangerous and still contaminated by end users
-Higher temperatures can make it necessary for some terpenes and other smaller compounds
While there are many ways to extract CBD from hemp, some methods are more effective and safer than others. Understanding the differences is crucial, as how you extract CBD can affect the purity and potency of the final product.
To activate CBD efficiently and to get the most from your plant material, you’ll need a precision cooker (also known as a decarboxylator) which can maintain exact temperatures needed for the full activation of CBD and other cannabinoids. With precision heating, decarboxylators extract a higher percentage of beneficial plant compounds than cruder methods and are a worthwhile investment for anyone who takes CBD oil regularly or wants to make a consistently good product.
To make CBD oil you only need two primary ingredients: hemp and a carrier oil. Hemp flowers that are high in CBD will yield the best results, and if you can’t find them locally, you can order them online. After decarboxylating the hemp flowers, you can then use them to make a CBD-infused oil.
Rather than smoking, you can activate these compounds through other means of heating. Some people bake hemp flowers in a slow oven for about an hour or use a slow cooker. These methods are inexpensive, but they’re also imprecise and may not activate all the CBD.
What you’ll need to make CBD oil
Sacred Smoke Herbals sells high-CBD hemp flower that’s organically grown, lab-tested, and available in all 50 states. Use coupon code NOURISHED15 for 15% off.
We used the Ardent Flex for making this CBD oil. With multiple settings, you can use it to activate CBD as well as similar compounds. And, you can also use it to make herbal infusions. Save $30 with code NOURISHED.
Depending on their strain, cannabis may contain large or relatively low amounts of CBD. When you make CBD oil, choose a strain with a high CBD content so that you can extract the most beneficial compounds into your homemade oil.
A carrier oil is an oil that you use for herbal infusions. Coconut oil and MCT oil (which is derived from coconut) are popular carrier oils both in commercial and homemade CBD products.
For the purposes of this recipe, we are going to use a decarboxylation technique from cannabis chef Coreen Carroll, co-founder of the Cannaisseur Series.
Heat oven to 275˚F. Line baking sheet with tinfoil. Break up dry flower into pea-sized pieces with fingers or scissors and spread cannabis evenly onto baking sheet. Place baking sheet in oven and bake for 20 minutes. Remove from heat.
While there are many decarboxylation methods, activation is achieved by exposing dry cannabis to heat between 240–295˚F for 20 to 60 minutes. Heat for a shorter time at higher temperatures or for a longer time at lower temperatures between this range. For example, if you’re using a higher temperature (between 275˚F and 295˚F), bake for 20 minutes max and be careful not to overcook. Overheating can degrade cannabinoids and terpenes.
A note about cannabis decarboxylation
Place cheese cloth in fine-mesh strainer over clean 8-ounce Mason jar. Pour infused olive oil through cheesecloth into jar. Gently press to extract the oil. Avoid squeezing cheesecloth to minimize unattractive chlorophyll flavors.
In sterilized 16-ounce Mason jar, combine cannabis flower and olive oil. Seal tightly.
In order to unlock the full potential of CBD, you must decarboxylate your dry cannabis flower before integrating it into a recipe. Decarboxylation is a heating process that triggers the chemical reaction that releases the carboxylic acids from CBD. In other words, you are converting CBDA to CBD.
Fill small saucepan with 3-inches water. Place Mason jar in pan and heat on low. Using candy thermometer, bring to gentle boil at 200˚F for 2½ to 3 hours. Make sure water does not exceed 211°F. Add water to saucepan as needed to compensate for evaporation. When finished, remove Mason jar safely with an oven mitt and let cool.
