CBD extract process

Posted by Christopher 12/02/2019 0 Comment(s)

Regarding our CBD processes at UK CBD Oils, we use only certified strains of (Cannabis Sativa L), approved by the European Union, which is sustainably grown and harvested in the EU, without the use of any pesticides, herbicides, fungicides, GMOs or other chemicals.

Our first stage extraction is a very gentle supercritical CO2 extraction which produces the raw extract which you can find in the syringes that we sell. 

We then winterised the raw extract, using another very gentle processes of freezing and filtration to remove the naturally occurring plant wax, to give the extract a liquid consistency which is required for the oil droppers.

Both the raw paste and winterised oil is raw full spectrum, as close to the natural plant as possible. The extract is rich is CBDA, contains traces of many different cannabinoids, terpenes, flavonoids and other natural minerals — just as nature intended. This is achieved through very gentle extraction and filtration, only at low temperatures.

What is Supercritical CO2 

Supercritical CO2 extraction is another way of talking about CO2 extraction. Although it's not the only form of extraction, when we talk about the most commonly used extraction, we are referring to supercritical CO2 extraction.

CO2 extraction is already a conventional extraction method in the food and herbal supplement industries. For instance, CO2 is used in making carbonated soft drinks. Also, many people may not realize that CO2 extraction is necessary for the removal of caffeine from coffee beans in order for manufacturers to produce decaffeinated coffee. Furthermore, CO2 is used as an extraction solvent in the production of essential oils.

CO2 extraction is now an incredibly important component in the cannabis industry as well.

Here's how it all works.
The first step is when the extractor takes gaseous CO2 and runs it through a chamber where it will be subjected to extremely low (-70°F) temperatures. This causes enough pressure to cause the gas to change into a fluid (hooray, science). In this state, CO2 exhibits special properties so when it is reheated and pressurized, it then becomes supercritical.

Next, the supercritical fluid passes through a chamber that contains the raw cannabis material. The supercritical fluid can pass through the raw cannabis while gently dissolving the membrane of the trichomes. This allows for the capturing of their many active compounds.
