Supercritical CO2 extraction can be carried out at close to room temperature (35-40°C) and under CO2 gas, effectively preventing the oxidation and dispersion of heat-sensitive substances and maintaining the active ingredients of medicinal plants.
As an inactive gas, CO2 has no chemical reaction during the extraction process and is non-flammable, tasteless, odourless and non-toxic, so the safety is very good.
CO2 is cheap, pure, easy to produce, and can be re-cycled in production, thus effectively reducing costs.
Adjustment of process parameters: pressure and temperature can be the parameters of the extraction process. By changing the temperature and pressure to achieve the purpose of extraction, the process is simple and easy to master, and the extraction speed is fast.
Product purity and quality: Supercritical CO2 extraction technology can improve the extraction efficiency and reduce the chemical pollutants in the extraction process, thus greatly improving the quality of the product.
