With the legalization of industrial hemp with the US Farm Act of 2018, hemp-derived products like cannabidiol (CBD) infused health and wellness products became popular among users. They are made using different types of CBD extracts obtained from the flowers, leaves, and buds of the plant. One of the most important factors that control the quality of the cannabidiol extract is the temperature used during the extraction and distillation. Remember that the wrong temperature will adversely affect the quality of the finished product. Read on to know more about the importance of temperature control in hemp CBD processing.
Temperature Control In CBD Extraction Process
The extraction process is used for separating the cannabinoids, terpenes, and other phytochemicals from the hemp plant materials like leaves, buds, and flowers. Besides, the compounds present in the CBD extract depends on the extraction method used. For example, full-spectrum hemp extract is one of the most popular extracts used in CBD health and wellness products.
Cannabidiol manufacturers use both polar and non-polar substances for dissolving phytochemicals found in hemp plant parts. Heat plays a critical role in this process as it influences cannabinoids to be dissolved. Also, remember that excessive heat can cause the loss of cannabinoids through oxidation.
Different Types Of CBD Extraction Processes
Supercritical CO2 Extraction: At room temperature, carbon dioxide is in the gaseous form, and it is not useful for CBD extraction. But, at supercritical temperature, it has the properties of a gas and a liquid. So, it can be used for extracting cannabidiol (CBD), other phytocannabinoids, and terpenes from hemp plant parts. Furthermore, by adjusting the temperature and pressure, you can fine-tune the extraction process.
Pressurized Hydrocarbon Extraction: In this extraction method, pressure and heat are utilized for condensing and evaporating the solvent used for extracting cannabidiol (CBD). Hexane, butane, methanol, and methylene chloride are some of the solvents used in this method.
In pressurized hydrocarbon extraction, first, the pressurized solvent is mixed with the hemp plant parts. After soaking, this mixture is sent through a screen to a collection tank. The screen is used for filtering out the solids. In the collection tank, the extract will settle down at the bottom of the tank, while the solvent rises to the top. Now, the tank is heated to evaporate the solvent, and we get the hemp CBD extract. Also, bear in mind that excess temperature can adversely affect the cannabinoids available in the final product.
These are some of the important points that you must know about the influence of temperature in hemp processing.
