CBD comes from cannabis. The name cannabidiol comes from right there. But how is CBD made/ what happens in the process of extraction and then infuse in a product we buy it online or in our local pharmacy store?
CBD extracted from the hemp plant, the reason we see “hemp extract” label most of the time on our CBD products in the ingredients list. Once the extraction is complete, the CBD then added to various products in the form of gummies, tinctures, capsules, and vapes, etc.
Extraction Of CBD
The most recommended is the CO2 extraction. CO2 is also the most expensive extraction method. Still, it produces the highest concentration of CBD, in which the result is a high-quality product. Abandoning the neurotoxic residue CO2 is one of the safest extraction methods.
Extracting CBD from the hemp plant is as easy as making cannabutter at home. But for nationwide manufacturing purpose with the full result, there are two primary methods for effective CBD oil extraction.
Each method clear-cuts benefits in creating a high-quality, high potent CBD product.
CARBON DIOXIDE (CO2) EXTRACTION –
CO2 is a flexible gas with a variety of commercial uses, includes extracted compound from the plant. The CO2 method uses the gas in “Hypercritical liquid” form as well as in its normal state.
During the CO2 extraction, the pressurized chamber called the closed-loop extractor and the pumps to expose high-pressure CO2 to a shallow temperature, resulting in a high amount of CBD extraction.
- In the act of beginning extraction, the two chambers doing its work the 1st chamber will hold pressurized CO2. In contrast, the second pressurized chamber will have a cannabis plant. The CO2 gas then compressed until it becomes liquid.
- The first chamber pumps co2 into the second chamber. The existence of hypercritical carbon dioxide breaks down the cannabis in the section causing the separation of oil and plant.
- Eventually, the oil and co2 then pumped into the third chamber. The gas then evaporated and what’s left is the pure CBD oil.
The CO2 extraction machinery units build to produce anywhere from 100 – 1,200 pounds of biomass in a single run. With this method, you can not only extract CBD on a massive scale effectively but can also remove a particular compound like terpenes.
Naturally present compound “terpenes” are infused with cannabis for its signature fragrance and flavour as well as for its potential medicinal benefits.
While the CO2 method is the most expensive because of the advanced machinery used in it, its incredibly safe and producing a high concentration of CBD oil resulting 92% and above purity rate.
ORGANIC SOLVENT EXTRACTION
The organic solvent extraction method is relevant to using CO2, but it is mostly cheaper and faster. Butane used in hemp extraction, but ethanol and propane are famous.
The closed-loop system used as the C02 extraction in the liquid butane, propane, or ethanol flow over the hemp, releasing the CBD, other cannabinoid and terpenes.
The solvent has to be precisely temperature regulated to separate the solvent from the final extracted result without harming it.
The main disadvantage of solvent extraction is that some solvent comes along with the impurities from the hemp material, which gives the final product not so pleasant taste.
Other extraction methods are = 1. steam distillation, 2. natural solvent extraction.
These methods are inexpensive and leave no toxic residue behind. Still, one disadvantage is the heat damages the CBD oil and the presence of chlorophyll affects the taste and lower concentration of CBD.
What after Extraction?
CBD oil detailed as “full-spectrum.” It means all the other cannabinoid includes CBDA, CBDV, THC, and others are still present. As long as the product has the amount of THC will be 0.3% or less. ( Makes legal in the US and UK)
Full-spectrum also contains other therapeutic elements from the hemp, such as terpenes and amino acids. Many people opt for full-spectrum oil because of the “companion effect”.
CBD users believe that it can engage the endocannabinoid system more affected when more cannabinoids are present. Despite, some people prefer no THC in their oil, even in the very low amount of THC.
CBD isolates are most preferred. CBD isolate created when the liquid is then cooled and purified into crystalline isolate form. The result is a white powder with no flavour; it’s flavourless, it contains CBD isolate less expensive per milligram, contains no THC, no flavour, no smell.
Whether it is CBD isolate or full-spectrum, the CBD oil is added to other substances to make a CBD infused product. CBD oil tinctures created with the carrier cannabis or coconut oil.
- CBD gummies created by adding CBD oil and natural flavouring.
- CBD oil can be added in any edible goods, e.g., chocolate, brownies, fresh juice, tea, coffee, cakes daily food etc.
- CBD oil also comes in capsules and soft gels
- There are CBD vape oils too which is created by the combination of vegetable oil glycerine and propylene glycol, so that’s it’s suitable for inhalation. The natural flavour added for preferred taste.
Other products of CBD are in various essential oil, body butter, waxes, moisturizer, balm, and other tropical.
