CO2 extraction of natural plant essential oil
Advantages of essential oil supercritical CO2 fluid extraction
Low extraction temperature
The supercritical CO2 extraction method requires a low temperature, the reaction temperature is generally 35~55℃, and the entire reaction process is carried out under the CO2 gas envelope, which can effectively prevent the oxidation and escape of heat-sensitive components;
Therefore, the effective ingredients can be better preserved without being destroyed or secondary biochemical. Moreover, for substances with high boiling point, low volatility, and easily decomposed when heated, the extraction temperature is much lower than its boiling point, so the extraction effect is better.
No chemical solvent residue
Since no organic solvent is used for extraction during the extraction process, the final extract has no chemical solvent residues, which prevents the residue from harming the human body and damage to the environment, and ensures the pure naturalness of the extract.
When the supercritical CO2 extraction method is used to extract substances, the extraction and separation are combined. When the CO2 fluid saturated with the extract enters the separator, the CO2 fluid and the extract are quickly separated into gas and liquid under the influence of pressure drop or temperature change. Two-phase, not only greatly improves the efficiency of extraction, but also consumes relatively less energy, reducing production costs.
Safe and reliable
CO2 is inactive in nature and will not chemically react with the extract during the extraction process. CO2 is a non-flammable gas, odorless, odorless, non-toxic, and very safe.
Low production cost
Because the CO2 production process is mature and the preparation is relatively simple, the price of CO2 gas is relatively cheap, and the purity is high, and it can be recycled in production, which greatly reduces the production cost.
Simple process and fast extraction speed
In the extraction process, both pressure and temperature can become parameters for adjusting the extraction process, and the purpose of extraction can be achieved by changing the two parameters of temperature and pressure. When the pressure is fixed, the material can be separated by changing the temperature; on the contrary, by fixing the temperature, the extract can be separated by reducing the pressure. Therefore, the extraction process is simple and the extraction speed is faster.
Because supercritical CO2 extraction technology has many advantages as above, it has been widely used in the extraction of active ingredients of some natural products in recent years.
Case of supercritical CO2 extraction of herbal essential oil
Plant essential oils are unique aromatic substances extracted from plants. They are volatile at room temperature, have a low boiling point, and are small molecules that are easily absorbed by the human body and have certain health and beauty functions.
Some examples of CO2 extraction of plant essential oils from BIT are listed below
Supercritical CO2 extraction of essential oils
The conventional steam distillation is easy to cause the essential oils to volatilize or oxidize. In recent years, supercritical CO2 has been successfully used to extract essential oils from a variety of spice plants. The product has high purity and pure fragrance.
Supercritical CO2 extraction of cumin essential oil
Using cumin, a characteristic spice crop in Xinjiang, China, as raw material, the optimal extraction conditions for cumin essential oil were determined by orthogonal experiments: extraction pressure 30MPa, extraction temperature 40℃, extraction 3h.
The final extraction yield of cumin essential oil is 3.46%, which is higher than the traditional Soxhlet extraction method, and the product has more stable properties, higher purity, and does not contain fatty acids and other non-polar substances;
Supercritical CO2 extraction of burdock essential oil
The volatile oil was extracted from the burdock root by supercritical CO2 extraction method. The similarities and differences between the organic solvent extraction method and the supercritical CO2 extraction method were compared. The obtained essential oils were analyzed by liquid chromatography. Product yield and essential oil quality are significantly better than organic solvent extraction method;
Supercritical CO2 extraction of peppermint oil
The supercritical CO2 extraction method of peppermint oil, compared with the traditional steam distillation method, the supercritical CO2 method greatly improves the yield of peppermint oil and the content of menthol, and the natural fragrance and color of peppermint are better retained, but this method is subject to extraction The pressure has a great influence. As the extraction pressure increases from 10MPa to 15MPa and then to 20Mpa, the color of the product changes from a reddish brown oil to a dark green oil to a dark green paste. It may be that some interfering impurities are also extracted. Therefore, special attention should be paid to the pressure.
