Supercritical fluid extraction cannabinoids
CBD - Cannabidiol is usually produced by extracting CBD-rich hemp plants. Extraction is a common separation process that takes valuable material from any material. Solvents (usually liquids) are required for any type of extraction.
Primarily used for solvent extraction of CBD from hemp plants is some types of alcohol. However, there are other solvents available. For example, by supercritical carbon dioxide-CO2 extraction.
Alcohol and CO2
It is necessary to mention the basic difference between these two solvents. We start drinking alcohol. Alcohol originates from organic materials because it is produced primarily through plant fermentation. In contrast to CO2, CO8 is a toxic gas. 10-2 The concentration of COXNUMX in the air can cause nausea, unconsciousness, and eventually death.
These are just the most obvious facts. More importantly for the extraction itself, CO2 extracts only non-polar chemical bonds, where alcohols extract polar and non-polar chemical bonds.
In simple terms, alcohol extracts more substance than CO2. It also applies to cannabis plants. Alcohol is a solvent made from plant plants.
CBD is better extracted from alcohol
As mentioned above (and in Resources), alcohol extraction provides more complex extracts. This is especially important for cannabis plants because they contain a very wide variety of substances, some of which are unknown even today. Especially soluble in water, various oils, polysaccharides, acids and other substances.
Water-soluble substances are very important because the human body is made of 70% water, making these substances easier to absorb. Therefore, the CO2 extract misses many valuable compounds hidden in marijuana.
CBD and its absorption
Another important thing in alcohol extraction is the esterification of organic acids. Esterification occurs when organic acids (such as other acid forms of CBDa and cannabinoids) react with alcohol. The esters produced are soluble in water, making the extract easier to absorb into the body.
In other words, alcohol-extracted CBDs are more bioavailable and therefore have greater medical potential.
