Over and over again, consumers are being interested as to how will be the process of extracting essential oils. Multiple removal methods are available for extracting the oil from the plants. The methods for an essential oil extractors can be used which includes CO2 extraction, solvent extraction, steam distillation, and also cold press extraction.
There 4 kinds of extractions being used:
1. CO2 Extraction
2. Cold Press Extraction
3. Steam Distillation
4. Solvent Extraction
CO2 EXTRACTION
The supercritical CO2 extractions utilize fluid CO2 as the solvent to drag the lipids, constituent essential oils, and some other desired materials out of that plant material. This CO2 solvent fluid has removed from its final product by altering the pressure and therefore changing the ability to work as a solvent.
There is a marijuana process that utilizes the supercritical CO2 procedure for the careful oil extraction of the hemp plants. The process is nonflammable and nontoxic, and so it tenders the best security and stability when compared to the other kinds of extraction methods. This supercritical CO2 extraction system does very little harm also to the compounds of the oil, and that is why it is considered as the go-to system in the food business.
STEAM DISTILLATION
Most of the other essential oils had been extracted through the steam distillation. The extraction of these essential oils through steam distillation happened when a steam vaporized the compound of the plant material. Eventually, the compounds will turn into condensation which will be collected.
SOLVENT EXTRACTION
This solvent extraction of the essential oils employs the food grade solvents such as butane, ethanol and hexane for oil extraction coming from the plants and seeds. The plant material has been initially treated with the solvent, making the waxy aromatic compound that is known as “concrete.” The moment this concrete will be mixed with the alcohol and will be then exposed to heat, its oil particles are being released.
These kinds of solvent extractions will be able to raise the danger of environmental damage or of residual contamination.
COLD PRESS EXTRACTION
This cold press system for the oil extraction is also named as an expression or the scarification. This is most commonly utilized for citrus peels that will make products such as sweet orange oils of lemon oils. The underneath of the rind of the fruit is initially pierced to unlock the sacs of essential oil, and then the entire fruit is being pressed to press out the oil.
If the cold press extraction has been used with the hemp seeds it will come out with hemp seed oil. It is the nutritional supplement that has been usually used in cooking. If the hemp seed oil had so many minerals and vitamins it only has the trace amounts of the CBD and will not produce any CBD extract oil.
You can learn more regarding the difference of the CBD oil and hemp seed oil when you are fond of reading about their articles and are into researching as well.
