The co2 Extraction Process of 4 Extracts of Tobacco

CO2 extraction is a widely-used method for creating high-quality extracts used in the tobacco industry. This process utilizes carbon dioxide at high pressure and low temperature to extract desired compounds from tobacco leaves. In this article, we will discuss the CO2 extraction process for four different tobacco extracts.

CO2 extraction process

Nicotine Extract

Nicotine is a key active ingredient in tobacco that is widely used in nicotine replacement therapies. CO2 extraction is an efficient method for nicotine extraction because it does not leave behind harmful residues that can be found in other extraction methods. To start the CO2 extraction process for nicotine, tobacco leaves are loaded into the extraction vessel. Here, supercritical CO2 is used to extract nicotine from the leaves. The nicotine-rich CO2 is then transferred to another vessel, where the CO2 is evaporated, leaving behind a nicotine-rich extract.

Process ParameterValue
Temperature40-50°C
Pressure200-300 bar
Flow Rate5-10 L/min
Yield0.3-1.5%

Tobacco Absolute Extract

Tobacco absolute is a dark brown, oily substance with a strong tobacco scent. It is used in perfumes, flavors, and aromatherapy products. The CO2 extraction process for tobacco absolute involves the use of CO2 to extract the essential oil from the tobacco leaves. The extraction process is carried out at low temperature and high pressure, ensuring that the tobacco absolute extract maintains its characteristic aroma.

Process ParameterValue
Temperature20-35°C
Pressure100-200 bar
Flow Rate2-5 L/min
Yield0.2-0.8%

Tobacco Absolute Resinoid Extract

Tobacco absolute resinoid extract is a dark brown, solid substance with a characteristic tobacco scent. It is used in perfumes and aromatherapy products. The CO2 extraction process for tobacco absolute resinoid extract is similar to that of tobacco absolute extract, but the extracted substance is further processed to create a resinoid extract. The resinoid is obtained by removing the solvent CO2 from the extract, creating a solid and resinous tobacco extract.

Process ParameterValue
Temperature25-40°C
Pressure150-250 bar
Flow Rate3-8 L/min
Yield0.3-1.0%

Tobacco Oleoresin Extract

Tobacco oleoresin extract is a thick, honey-colored extract with a strong tobacco aroma. It is used in the unification of flavors and fragrances. The CO2 extraction process for tobacco oleoresin extract involves the use of CO2 to extract essential oils and other compounds from the tobacco leaves. The extracted substance is further processed to create a thick, sticky extract that is rich in aroma and flavor.

Process ParameterValue
Temperature30-45°C
Pressure180-280 bar
Flow Rate4-10 L/min
Yield0.5-1.5%

Summary

CO2 extraction is a safe, efficient, and non-toxic method for creating high-quality tobacco extracts. With the proper combination of temperature, pressure, and other process variables, CO2 extraction can obtain a variety of tobacco extracts with specific aroma and flavor profiles. These extracts can be used in various applications, including nicotine replacement therapies, perfumes, aromatherapy products, and flavors. Therefore, CO2 extraction is an essential technique in the tobacco industry.
