85 different compounds are found in the cannabis plant one of which is called CBD which stands for cannabidiol.
In the production of hemp with CBD extraction in mind, it must first be noted that not all the varieties of seeds in circulation are suitable. In fact, to produce prima hemp plants from which to extract CBD, it is necessary to cultivate only certain varieties of hemp, those genetically richest in CBD.
When the farmer has selected the variety of seed to be cultivated, the seed is planted. Sowing takes place in spring and harvest in summer. Then things start to get interesting. There are two main methods of extraction namely:
- CO2 Extraction
- Method of ethanol oil and canola
Some extraction techniques tend to be safer and more effective than others. It is important to note that some cannabis oils are made from neurotoxic solvents. These are called hexane and butane, these solvents may leave hazardous residue that could potentially compromise certain immune functions and disrupt the healing process.
How is CBD Processed 1. Supercritical CO2 extraction
This method called supercritical CO2 is the safest and most efficient industrial extraction system, as well as the most expensive in economic terms.
Used in the mining industry to extract resins and resinoids, it is also used in food extraction processes such as coffee, tea, and other substances.
The supercritical CO2 process consists of cooling and compressing carbon dioxide up to a maximum of 10,000 psi (think that a car wheel is at 300 psi of pressure. When compressed at these levels carbon dioxide becomes “supercritical” and starts to turn into liquid.
In the process of extracting hemp oil. The result of this procedure is a highly concentrated and totally pure CO2. The CBD oil that passes through the supercritical extraction is a product based on full spectrum cannabinoids. This produces a transparent with a light amber colored extract.
How is CBD Processed 2. Method of ethanol oil and canola
This extraction system is considered extremely safe, more economical than the previous one.
Ethanol is a substance commonly found in paints, felt-tip pens, mouthwashes, perfumes and deodorants. This substance is mixed with water, so it is considered an excellent solvent.
Although ethanol can be used to extract the full range of cannabinoids and essential oils of cannabis, it is not without its drawbacks.
First of all it must be said that ethanol is a polar solvent, and this means that it will easily mix with water and dissolve the water-soluble molecules. Together with cannabinoids and essential oils, this procedure will also tend to extract chlorophyll. This method will produce a colored substance of greenish hues. Chlorophyll can be removed by filtering the extract, with higher costs for those who choose this technique.
Cannabinoid extraction through the chemical solvent procedure is a process that does not cost companies much. The necessary equipment is relatively simple equipment.
So what extraction method do we use?
All CBD products listed on the store use a CO2 extraction method which employs the use of carbon dioxide placed under high pressure and extremely low temperatures to preserve, isolate, and maintain the purity levels of the CBD oil. CO2 extraction process requires rather expensive equipment. The operational learning curve is also greatly underplayed, but the final product is safer. It is also more potent and free of any chlorophyll.
How CBD is processed can very easily make a difference in quality and that is why we here at the CBDstore.co.za take pride in ensuring all standards of quality, purity and potency are met at all times.
