CBD Oil: A Guide to Supercritical CO₂ Extraction
Do you want the best cannabis concentrate? CO2 provides the best benefits
Guide to Supercritical CO2 Extraction
Many patients prefer inhaling oil as vapour or using oil as a tincture. But are you truly getting the best CBD oil? To get the most benefit from CBD healing, you should find CBD that was extracted using supercritical CO2 extraction.
Using carbon dioxide (CO2) extraction is common for several types of food and medication. But it's gaining popularity in the marijuana industry. For some brands, supercritical extraction is becoming their preferred method of CBD extraction. Do you want the best cannabis concentrate? Find out more information about CO2 extraction and how it benefits marijuana users.
Supercritical CO2 Extraction
There are many ways to extract CBD from cannabis and hemp. One of the most common ways of extracting CBD is through butane or hexane.
Butane or hexane melts and removes resin glands, also known as trichomes, and strips them to an oil or wax. This method produces strong concentrates, but the solvents can be toxic. Ethanol is one of the most common extraction processes. This process uses high-grade grain alcohol to create high-quality CBD. However, it destroys plant waxes. These waxes offer several health benefits that are vital to patients.
For edibles, olive oil extraction is usually used. This process is both safe and effective, but CBD oil doesn't last as long. This is why more CBD suppliers are using the subcritical method. Carbon dioxide is put under high pressure to isolate and preserve CBD oil. The C02 also maintains purity, resulting in high-quality CBD.
WHY CARBON DIOXIDE
Carbon dioxide does more than guarantee fresh CBD oil. Supercritical extraction is environmentally-friendly, safer, cleaner, and far less toxic than using other solvents. Carbon dioxide is a gas. But depending on the temperature, it can change to a liquid or a solid. The process of changing carbon dioxide from a gas to a liquid is called the supercritical process. Carbon dioxide needs to be heated above 31.1 degrees Celsius with critical pressure at 1,071 to turn into a supercritical liquid.
How can supercritical liquids be used as a solvent? When CO2 becomes a supercritical liquid, it can pass through porous solids and dissolve materials. When supercritical CO2 is extracted from cannabis, the maximum amount of CBD is drawn without any unwanted products such as chlorophyll. The supercritical extraction process is also one of the safest methods. No toxic solvents are used during the process. Carbon dioxide acts as a solvent and is safer than flammable solvents such as butane and hexane.
THE EXTRACTION PROCESS
Do you want to know how the CO2 extraction process works? Here's a simple outline:
- An extractor chamber is filled with cannabis or hemp
- Pressurized carbon dioxide gas is pushed into the chamber
- The carbon dioxide dissolves the cannabinoid compounds
- The cannabis oil particles are carried to a cyclonic separator
- The cannabis oil and carbon dioxide separates
- The system is closed-loop, so the carbon dioxide rises out of the separator to be re-used
- The cannabis oil descends in a collection vessel
- From here, the CBD oil is used for various products or the oil is used by itself.
SUPERCRITICAL CBD BENEFITS
The supercritical process helps us receive the most CBD oil. For those who use CBD oil medicinally, you'll receive a more potent medication.
Extracting CBD with carbon dioxide also provides other benefits. These include:
Make a Wide Variety of Consistencies
Since you're extracting pure CBD concentrate, it's very customizable. When the CBD is extracted, you can continue the process and create shatter, wax, and budder. And the best part? One machine can utilize these processes. Imagine getting high-quality shatter at a lower price than what you're buying now.
Develop New Strains
When the benefits of CBD are fully understood, there's more room for innovation. The miraculous healing benefits can be extracted and used to treat individual conditions. Imagine taking CBD specifically designed to reverse Alzheimer's? Or a CBD strain that destroys cancer cells? While there's no promise this will happen, it's definitely a possibility.
Supercritical CO2 has bacteria-killing properties. This means no strain of microbes, mould, mildew, or mites are left in your CBD oil. Many different industries kill off bacteria and mites with lethal chemicals and pesticides. CO2 extraction prevents the need for using these dangerous compounds. This results in marijuana that's healthier to consume. Without the interference of bacteria, the shelf-life of supercritically extracted CBD is longer.
Have you noticed your CBD oil tastes off? That's the butane and other toxic solvents destroying the natural marijuana taste and aroma. That lovely smell and earthy taste are a result of terpenes. When solvents such as CO2 are used on marijuana, it preserves the quality of terpenes. More terpenes also equal more healing. Terpenes enhance the medicinal benefits of CBD.
A BETTER UNDERSTANDING OF CO2 EXTRACTION
Supercritical CO2 is an innovative and effective way to extract CBD oil. When CO2 is exposed to hot temperatures at high pressures, it turns into a liquid. Using carbon dioxide as a solvent results in CBD with enhanced purity and better taste. The CBD can be used as an oil or even a wax or shatter. Supercritical CO2 is safer than any other solvents and can provide us with a better understanding of CBD.
