As the popularity of CBD flower continues to grow, so does the interest in new extraction methods. Extracting cannabinoids from hemp plants is key to producing a wide range of CBD products, from tinctures and topicals to edibles and beverages. But before getting into any extraction method, it’s important to understand what exactly makes up CBD Flower.
CBD flower is the dried and cured flowering tops of female hemp plants that are rich in cannabidiol (CBD). It also contains other beneficial compounds such as terpenes and flavonoids. With its earthy flavor and aroma, many people enjoy vaping or smoking CBD flower for its potential therapeutic benefits. However, if you want to create more diverse products with your cannabis flowers, you need to extract their essential compounds first using one of several available methods. Here’s a look at the different types of CBD flower extraction techniques currently used today:
CO2 Extraction Method
This is arguably one of the most popular methods for extracting cannabinoids from hemp plants due to its efficiency and safety profile. During CO2 extraction, pressurized carbon dioxide gas is pumped through hemp material containing high trichomes (stalked secretory cells). This process separates out potent oils containing cannabinoids like THC and CBD along with other beneficial compounds like terpenes and flavonoids. The end result is an incredibly pure form of concentrates known as “shatter” or “hash oil” that can be easily mixed with other ingredients for use in various products like edibles or tinctures.
Ethanol Extraction Method
Another common method for extracting cannabinoids from hemp materials is ethanol extraction. In this technique, food-grade ethanol is heated up until it evaporates then combined with crushed cannabis buds under pressure at low temperatures—typically around 100 degrees Fahrenheit—for about 30 minutes. This process allows for the separation of valuable plant matter such as waxes, lipids, chlorophylls, terpenes, flavonoids, sterols and cannabinoids like THC and CBD without causing any damage to them in the process. The resulting crude oil can then be further refined through distillation or winterization processes if desired before being added into products like edibles or topicals.
Butane Hash Oil (BHO) extraction method
Probably one of the least safe but still commonly used methods of extracting cannabinoids from hemp material is the butane hash oil (BHO) extraction technique. As the name suggests, this involves the use of highly flammable liquid butane or propane gas, which can be harmful if inhaled directly, or even cause serious explosions if mishandled during the production process. BHO extracts tend to have very high concentrations of both THCA/THC and CBDA/CBD, making them ideal for making dabs (highly concentrated cannabis extracts), although they may contain some unwanted residual solvents, including butane itself, which can cause health concerns if consumed in large quantities over long periods of time.
Rosin Tech extraction method
For those looking for a safer alternative that produces equally potent results without all the hazards associated with BHO extraction, Rosin Tech may be the perfect option. This method uses heat combined with pressure applied directly to buds or trim, resulting in an oily substance called ‘rosin’ which can then be collected after cooling. What sets this apart from the other techniques mentioned here is how fast it works, taking just a few seconds to produce full spectrum extracts without the need for additional solvents, meaning there is no risk of ingesting residual solvents either. In addition, because the temperature doesn’t go above 120°F there is less chance of degrading sensitive components present in plant matter, making rosin much closer to actual plant material compared to processed concentrates obtained via alternative forms of extraction.
Ice Water Extraction Method (Bubble Hash)
Ice water extraction relies on freezing temperatures to separate precious trichome heads filled with valuable compounds while leaving behind unwanted impurities such as leaves, stems etc. To start simply add crushed buds to a bucket of cold water, then stir the mixture vigorously until trichomes are broken off. These will sink to the bottom thanks to density difference between solid particles and liquid solution leaving surface easy to collect later on strain bag filter out excess plant residue and finally squeezes out remaining moisture pressing against bubble bag yield sticky concentrate referred to as ‘bubble hash’ which contains high concentrations of THC/CBDA depending on original strain quality may vary so always best check lab results ensure safety consumption users.
Extracting cannabinoid molecules from hemp plants has become increasingly popular in recent years due to rising consumer demand, and growing awareness of the benefits derived from these compounds when ingested orally, applied externally to the body in the form of topical creams, ointments etc. Ultimately selecting the right type of equipment depends largely on the intended application, what sort of product producer is trying to create, whether smokeable, dab, edible beverage etc each having its own set of advantages and disadvantages based on cost-effectiveness ease of preparation safety considerations ultimately deciding factor should come down to individual expertise budget limitations resources available they carry project completed successfully.
