This video is different than the others you saw about the CBD product reviewing. Here is Nick talking about the fundamentals between co2 and solvent-based extraction. The first method Nick starts with is the co2 extraction method. Probably you guys already know that co2 is the gas and present in the air. To make co2 a solvent, it needs to go into the subcritical phase. In that phase, you compress and heat the gas to make it fluid. So, this is called supercritical or subcritical fluid extraction. The method is old and used in coffee or vanilla artisanal extracts. When people start looking for CBD extract, this industry starts using this process around ten years ago.
The difference between co2 solvent as compared to other solvents like hydrocarbon and ethanol is that co2 does not do a great job while extracting the cannabinoids. CBD structure is like the shape of the mushroom, and that contains all the essential ingredients like Terpenes, CBD, or THC. Extraction methods are used to extracts all the necessary components from the mushroom-like structure. Nick said the co2 extraction method is not perfect because it takes a lot of power and pressures up to 1500 to 5000 psi. In co2 extraction, the run time is 2 hours, and if you add more product into it, the time will be ore longer. The equipment for co2 extraction is expensive and needs precautions.
The other method Nick talked about is solvent-based extraction. Butane and Propane are the two non-polar solvents with a light boiling point; they locked the cannabinoids and yield a beautiful light color product. They need more money to engineer the equipment but not like co2. Compare to the co2 extraction method, butane and Propane needs 50 to 150 psi pressure. In Nick’s opinion, Solvent extraction method is safe to use, and their company successfully installed the hydrocarbon equipment across the globe. He says that the hydrocarbon method gives the best profile out of the cannabis and hemp plant.
Another solvent is now ethanol, and Nick is discussing it. However, the problem with ethanol is its polarity because it is a polar solvent. The problem is that it bounds with other unwanted water solubles as well. As per the fundamentals comparison, ethanol is best because it does not require any vapor pressure for extraction.
This is the best-explained video I ever saw; I concluded after watching and hearing Nick. Nick probably has all the scientific facts and information about the extraction methods and solvents. What he presented is clear and easy to understand. I like how Nick explained the lock and key approach to elaborate concepts. He talks with the perfection that you cannot distract while listening to him.
