There are many factors that affect the quality of CBD products when you buy from a CBD shop. The method used to extract CBD is the most important. CBD extraction is a fascinating topic. However, the technical terminology can seem overwhelming.
It’s easy to see extraction in relation to a process that you are familiar with. CBD extraction is the same process that goes into making your morning cup.
What Is CBD Extracted?
CBD is a cannabinoid that can be found in hemp plants, but it is most concentrated in flowers. The process of extracting cannabinoids and other compounds from plant material is called extraction.
The cannabinoid content in cannabis flower clusters is anywhere from 1 to 30 percent after it has been harvested, dried, and cured. The genetics of the strain, as well as the timing of harvest, will determine the cannabinoid profile.
Different CBD Extraction Methods
There are many ways to extract CBD or other cannabinoids. These methods range from old techniques to modern, advanced methods. There are two main types of extraction methods: solvent extraction and manual separation.
Hand concentration is the best and most simple method to extract cannabinoids from hemp plants. Different cultures have used cannabis concentrates to heal and for religious purposes for centuries. These are not extractions but mechanical methods to extract cannabinoids.
The following methods can be used to separate CBD and other cannabinoids by hand:
Traditional Dry Sieving – This method is used in Central Asia and the Middle East. It involves drying, aging, and wrapping cannabis in a cloth parcel. To extract the powdery trichomes from the parcel, it is beat with tools on a collection vessel. These can then be used to make resins, brew beverages, or mix into food.
Dry Ice/Dryscreen Method: This extraction method is a modern version of traditional sieving. It involves combining dry hemp flower and dry ice to supercool resin and make the stalks brittle. To separate the trichomes from plant material, the cool plant material is spread on a fine mesh screen. The fine mesh allows the tiny resin grains to pass through, while the buds are left intact.
For centuries, solvent-based extraction methods have been used to extract concentrates and other beneficial extracts. Modern solvent extraction techniques have elevated solvent extraction to a whole new level.
These are the most common solvents for CBD extraction:
- Ethanol Extraction
Alcohol is still used to extract CBD, just like traditional tinctures. The process hasn’t changed too much from the old alcohol tinctures. However, the extraction of ethanol these days takes place in a controlled environment. The ethanol is then removed at the end.
Ethanol extraction is done by soaking the hemp in alcohol. The liquid then dissolves the cannabinoids. The ethanol is then evaporated, leaving behind a concentrated oily residue that contains the hemp compounds.
- Vegetable Oil Extraction
The easiest way to extract CBD from oil is perhaps. This method is popular for DIY home extractors, as it requires only basic kitchen equipment. You can extract fat-soluble cannabinoids from almost any edible oil. Coconut oil, hemp seed oil, and olive oil are the most well-known.
- Co2 Extraction
This extraction method is widely used in a variety of manufacturing processes. It is the most popular way to extract CBD.
Carbon dioxide (or CO2) is a colorless, odorless gas that can be found in its natural state. It can be found everywhere, from the air we breathe to the fizz in our seltzers.
