Supercritical CO2 extraction of curcumin/turmeric essential oil
Curcumin is a chemical component extracted from the rhizomes of some plants in the Zingiberaceae and Araceae family. Among the above-mentioned pure natural plants, turmeric contains about 3% to 6%, which is very rare in the plant kingdom with diketones. The pigment is a diketone compound.
Curcumin is orange-yellow crystalline powder with a bit bitter taste. Insoluble in water, it is one of the important natural pigments allowed to be used in the food industry and has important development and utilization value. Modern pharmacological studies have shown that turmeric has many pharmacological effects such as anticoagulation, anticancer, lowering blood pressure, lowering blood lipids, choleretics, antibacterial, anti-inflammatory and antioxidant. The main active ingredient of plant turmeric is curcumin, which has a wide range of pharmacological activities and can be widely added to various daily chemical products such as toothpaste, soap and cosmetics.
Curcumin is further divided into demethoxycurcumin, demethoxycurcumin and curcumin. The main extraction methods of curcumin can be divided into organic solvent extraction and water extraction. In the existing extraction method, curcumin is easily degraded during the process of extracting and recovering the solvent.
Carbon dioxide is non-toxic and has no residual solvents. Supercritical extraction technology can extract turmeric at room temperature without destroying the biological activity of turmeric. Supercritical CO2 fluid extraction at room temperature replaces the traditional extraction methods (steam distillation and organic solvent extraction).
The characteristics of supercritical CO2 extraction of curcumin/turmeric essential oil
- The low-temperature extraction of supercritical carbon dioxide fluid is slightly higher than the low-temperature extraction at room temperature (31°C), and will not change or damage components that are easily heated; it is suitable for the separation of heat-sensitive substances.
- Colorless, odorless, non-toxic, no residue, environmentally friendly, gas under normal pressure, no residual odor will damage the product, and easy to separate from the product, and maintain the taste of the original material.
- Carbon dioxide is chemically inert, does not contain oxygen, and does not have a chemical effect; it will not change or destroy the effective ingredients in the extract. And the supercritical extraction process is closed, because the product extracted with supercritical carbon dioxide fluid can extend the shelf life.
- The optimal solubility of each component can be obtained by adjusting the extraction temperature and pressure; or by adding a modifier and using high-purity carbon dioxide to obtain a high-purity extract.
- In the traditional solvent extraction process of a general factory, if organic solvents are added, not only will the extraction time be long and will seriously affect the environment, ecology and cost, in addition, due to the oxidation effects of organic solvents, water and other by-products may be produced, but the use of carbon dioxide will not Will produce oxygen chemistry and the above-mentioned adverse effects.
Characteristics of curcumin/turmeric essential oil extracted by distillation method:
Although the distillation method can extract most essential oils, because essential oils are sensitive to heat, the produced essential oils will deteriorate due to high temperatures and cannot retain the original components of the substance. The process is very long, and drying requires high temperatures to remove moisture.
Characteristics of curcumin/turmeric essential oil extracted by organic solvent extraction method:
However, organic solvents are not easy to separate after extraction, and chloroform or phenyl solvents are carcinogenic.
Curcumin is an orange-yellow crystalline powder with a bit bitter taste. Stability transfer to reducing agent, strong coloring (not to protein), it is not easy to fade after coloring, but it is sensitive to light, heat, iron ions, light resistance, heat resistance, and iron ions resistance. Therefore, when the pH is greater than 8, curcumin will turn from yellow to red.
The main uses of curcumin
Curcumin is a commonly used medicine, and its main biologically active ingredients are curcumin and volatile oil. The former has the effects of lowering blood lipids, anticoagulation, anti-oxidation, choleretics, and anti-cancer; and mainly has anti-inflammatory, antibacterial and antitussive effects. The class exerts its anti-cancer effect by inducing malignant tumor cell differentiation, inducing tumor cell differentiation and inhibiting tumor growth at various stages, and has a wide range of clinical applications.
Curcumin can be used as a yellow edible pigment. Curcumin is usually used for the coloring of beverages, candies, cakes, sausage products, starches, sauces, canned foods and other foods, as well as for the coloring of cosmetics, medicines and drugs. Dry, curry powder, etc. have a long history; curcumin can also be used in pickles, ham, sausages, apples, pineapples, and chestnuts.
Curcumin can be used as an acid-base indicator. When the PH value is 7,8, it will be yellow, and when the PH value is 9.2, it will be reddish-brown.
Experiment on supercritical CO2 extraction of curcumin/turmeric essential oil
The effect of raw material particle size on the extraction effect
After the turmeric raw materials are crushed through different size sieves, they are placed in an extraction kettle for extraction. After the extraction is completed, the content of curcumin in the turmeric residue after extraction is detected, and the curcumin content of the raw materials is compared with the curcumin content of the raw materials to obtain the extraction rate of curcumin. In the experiment, the extraction pressure was maintained at 28MPa, the water bath heating temperature was 45°C, the entrainer 95% ethanol was input at a constant rate for one hour, and the ethanol was extracted and dried for 1 hour after input for 3 hours. Under the same conditions, the effect of different raw material particle sizes on the extraction effect was studied.
Influence, as the particle size of raw materials decreases, the effect of supercritical carbon dioxide extraction becomes better and better. When the particle size is reduced to 20 meshes, the extraction rate will not increase anymore. On the contrary, it will make the material sticky because the particle size is too small, which will increase the difficulty and cost of crushing. Therefore, the particle size of the raw material should be selected at 40 mesh.
The effect of extraction pressure on extraction effect
The turmeric raw material is crushed through a 40-mesh sieve (raw material particle size: 1mm) and placed in an extraction kettle for extraction. After the extraction is completed, the content of curcumin in the turmeric residue after extraction is detected, and the content of curcumin in the raw material is compared with the curcumin content. rate. In the experiment, the heating temperature of the extraction water bath was maintained at 45°C, the entrainer 95% ethanol was input at a constant rate for one hour, and the conditions were unchanged after inputting for 3 hours and then extracting and drying the ethanol for 1 hour.
The effect of different extraction pressures on the extraction effect was studied. With the gradual increase of pressure, the extraction rate of curcumin gradually increased, and it increased to the highest position at 28MPa. When the pressure increased to 35MPa, the extraction rate of curcumin decreased. Did not increase too much. The increase in pressure will greatly increase the load of the equipment and the operating cost and operation difficulty of the equipment, which is not conducive to large-scale industrial production. Therefore, the extraction pressure should be selected between 25 MPa and 28 MPa when the production is satisfied.
The effect of temperature on the extraction effect
The turmeric raw material is crushed through a 40-mesh sieve (raw material particle size: 1mm) and placed in an extraction kettle for extraction. After the extraction is completed, the content of curcumin in the turmeric residue after extraction is detected, and the content of curcumin in the raw material is compared with the curcumin content. rate. In the experiment, keep the extraction pressure at 28MPa, input the entrainer 95% ethanol at a constant rate for one hour, and then extract and dry the ethanol for one hour after inputting for 3 hours.
The effect of the heating temperature of the water bath of different extraction kettles on the extraction effect is studied. The temperature has a small effect on the separation effect. The general trend is that the increase in temperature is beneficial to the extraction, but on the one hand, it will also increase the energy consumption and increase the equipment. The processing cost, especially the industrialized extraction device, so I should choose about 45°C in the extraction process.
The effect of the amount of entrainer on the extraction effect
The turmeric raw material is crushed through a 40-mesh sieve (raw material particle size: 1mm) and placed in an extraction kettle for extraction. After the extraction is completed, the content of curcumin in the turmeric residue after extraction is detected, and the content of curcumin in the raw material is compared with the curcumin content. rate. In the experiment, keep the extraction pressure at 28MPa and the temperature at 45°C.
The effect of different amounts of entrainer on the extraction effect was studied. If no entrainer is used, the extraction rate of curcumin is very low, only 8.1%. It is part of the curcumin with lower polarity, and most of the curcumin remains in After the extraction is completed, the addition of the entrainer greatly improves the extraction effect, so that curcumin can be well dissolved in the co-solvent system of supercritical carbon dioxide and ethanol to be extracted from the medicinal materials, greatly increasing The extraction rate of curcumin.
And with the increase in the amount of entrainer used, the extraction rate also gradually increases, and reaches the maximum at the time of **. When energy consumption and equipment allow, and the cost is reasonable, especially on the premise of feasible industrial production, it is recommended to choose entrainer The usage is around **.
Experiment of extracting curcumin by industrialized supercritical dioxide or extraction equipment
On the P-50D 50Lx2 supercritical carbon dioxide extraction equipment, a trial production of extracting curcumin from the medicinal material turmeric was carried out. The medicinal material Salvia miltiorrhiza was 20 kg, the pressure of the extraction kettle was 28MPa, and the heating temperature of the hot water bath of the extraction kettle was 45°C. Input the entrainer 95% ethanol** kg at a constant rate of one hour, and input it for 3 hours, and the extraction rate of curcumin will reach more than 98%.
It is found through experiments that the extraction conditions are mild in the supercritical carbon dioxide extraction process, and the inert environment of supercritical carbon dioxide protects the heat-sensitive substances during the extraction process and is not easy to decompose. The use of supercritical carbon dioxide extraction technology can effectively extract curcumin from the plant turmeric, and the extraction rate of its effective ingredients is above 98%.
The best use conditions for supercritical carbon dioxide extraction of turmeric are: raw material particle size 40 mesh, extraction pressure 28 MPa, extraction temperature 45 °C, use amount of entrainer **, and use the P-50D commercial-grade supercritical extraction machine according to the best process conditions Trial production was carried out in China, which proved that the technology can be fully industrialized on a large scale.
