Whilst the yield is smaller than with supercritical, it also allows for lighter oils and other sensitive compounds that might otherwise be dismantled in the process to be extracted. However, the trade off is that heavier, more resinous material will typically get left behind.
The process involves flash-freezing the loosely chopped hemp extract, and then sieving the frozen trichomes through a mesh bag. These in turn can then be used as the basis for your cannabidiol oil—it’s really that simple.
The most expensive and most popular CBD extraction method (particularly amongst manufacturers offering a premium product) involves using CO2. This is because it provides a clean, precise extraction that massively reduces the contamination potential of other methods.
Solvent CBD extractions
A solvent extraction involves running the solvent in question—typically either butane or ethanol—to the hemp plant matter. This strips the cannabinoids into the liquid, which is then evaporated so as to leave behind a concentrated oily residue with the hemp compounds in.
The shared methodology between the two essentially entails running pressurised carbon dioxide across the hemp plant to strip away the desired phytochemicals (literally: plant chemicals). When treated to certain conditions, CO2 actually acts like a solvent, without any of the potential side-effects.
Cannabidiol is actually synthesised in the trichomes of the female hemp plant, alongside the other cannabinoids, terpenes, and flavonoids. The need to create CBD oils that retain CBD and other cannabinoids whilst removing the THC is part of why extraction techniques are so important.
As we’ve mentioned, CBD is actually a constituent in a vast sea of hemp compounds, so extraction isn’t as easy as it first may seem. However, all of these techniques were first developed for other purposes, like extracting essential oils from flowers.
There are a lot of factors that come into play when deciding which is the best extraction method. Each method of cannabidiol extraction has its benefits and drawbacks. To try and find an answer to the question above, we have to understand the different types of methods used in extracting CBD from hemp flowers.
In order to get premium high-quality CBD oil, a lot of care has to be taken during processing. It is important to note that even well-grown plants that have a high CBD percentage can fail to yield potent high-quality oil if the wrong extraction method is used. Simply put, the extraction method used usually impacts the quality, potency, purity, and effectiveness of the CBD oil that is produced.
A Detailed Analysis of The Methods Used in Extracting CBD Oil
There is no simple answer to this question. For starters, CBD can be extracted from the hemp flower using several different methods. Additionally, with each passing day, there are new methods of extraction that are being developed as the popularity of CBD products continues to grow.
As stated earlier, there are several methods used to process CBD oil:
Before we look at some of the techniques used in the extraction process, it is important to note that most processors of CBD oil usually select an extraction technique based on the goal of extracting the oil as well as the final use of the extracted cannabidiol.
• Co₂ extraction is an industrial process, making it highly expensive
• Requires expertise to perform correctly
Once decarboxylated, mix your plant matter with olive oil and heat it on the stove for several hours. CBD, other cannabinoids and essential terpenes will bind to the fats in the oil, creating an infused product. Finally, the mixture is left to cool before being filtered to remove any leftover plant material.
Second, since it uses CO₂, it produces CBD oils free from chemicals and contaminants. And, when the extraction process is over, you can either reuse the CO₂ or release it safely back into the atmosphere. Thanks to this outstanding level of control, supercritical CO₂ has become a leading tool extraction and one that Cibdol uses to create all of its CBD extracts.
Supercritical CO₂ CBD extraction
In this method, CO₂ is manipulated to enter a supercritical state. With characteristics of both a gas and a liquid, it’s pumped through raw plant material under controlled conditions, stripping away essential terpenes and cannabinoids without damaging them.
However, highly sophisticated extraction is only the beginning. Cibdol goes above and beyond for its customers, publishing a detailed analysis of every CBD product batch. Performed by an independent third-party, these analyses indicate levels of all common cannabinoids, allowing you to make the most informed decision possible.
Although there are many ways to extract CBD from hemp, some methods are much more efficient and safer than others. It’s essential to know the difference, since how you extract CBD affects the purity and efficacy of the final product.
• Allows for the extraction of clean and safe concentrates without the use of additional additives or contaminants.
• Offers highly efficient yields, getting the most out of the hemp plant.
• CO₂ extraction is sustainable and environmentally friendly
