How is CBD made?
Thanks for tuning into Xhale City's The 20 Days of 420. Where we discuss how CBD is made and what processes companies use to extract CBD.
"So CBD is a revolutionary product… but how is it made?
First Hemp is harvested and left to air dry in a ventilated facility. Once cured the flower is removed from the stems and ground down and poured into a closed-loop extractor.
All types of CBD oil is extracted by applying high pressure and low temperatures to the hemp plant.
One of the more common solvents involves supercritical (liquid state) Carbon Dioxide (CO2). Using CO2 minimizes the risk of leaving dangerous materials in the final product.
CO2 comes in contact with the plant, the pressure will cause the hairs or trichomes to burst open releasing the cannabinoids and terpenes. When the cannabinoids are released the molecules bind to the carbon in the pressurized CO2. Then the residual mixture is distilled to remove any solid plant material. Finally, the CBD oil is refined, the CO2 leaves the chamber and becomes a gas; leaving only the cannabinoids and terpenes.
Chromatography is a method to separate the cannabinoids via molecular structure. This process removes the THC, leaving only CBD and a few other components of the plant.
Ethanol (or alcohol) is another type of extraction method where the plant material is mixed into an ethanol bath. This process removes all the fats and lipids from the solution. Then the ethanol is removed from the oil in a rotary evaporator, where you use controlled heat and a vacuum to evaporate the alcohol and condense the oil. The mixture is distilled and you are left with oil.
We recommend to do some research and find out what extraction method CBD brands use before making a purchase."
