Application of supercritical CO2 fluid extraction

Supercritical CO2 fluid extraction technology is recognized as a “green and sustainable technology” because of its simple process, high product purity, good selectivity, no solvent or less solvent residue.

Supercritical fluid extraction technology has broad application prospects in many fields such as chemical engineering, energy, fuel, medicine, food, perfume, environmental protection, marine chemical industry, biochemical industry, and analytical chemistry.

Natural products

Supercritical CO2 fluid extraction technology has obvious advantages in the extraction of active ingredients from natural plants, mainly involving alkaloids, anthraquinones, flavonoids, saponins, polysaccharides, volatile oils, pigments, terpenes and coumarin compounds, etc. .

Food industry

Supercritical CO2 Extraction of Hop Extract

Hops are the main auxiliary material in beer production. It can impart unique bitterness and aroma to beer, and is a preservative and aromatic in beer brewing.

The traditional method of extracting hop extract is to use hexane, dichloromethane and other organic solvents for extraction, the product quality is poor, and there are chemical solvent residues.

The use of supercritical CO2 extraction of hop extract not only greatly improves the utilization of effective ingredients, but also brewed beer has better foam and flavor.

The raffinate of supercritical CO2 extraction of hops is used as raw material to extract hop polyphenols.

When the extraction temperature is 40°C and the extraction pressure is greater than 25MPa, the content of polyphenols in the extract is significantly increased, and the content of polyphenols in the product obtained at a higher extraction temperature does not increase significantly. From the raffinate of supercritical extraction hops Extracting hop polyphenols can improve the value of hops comprehensive utilization.

The supercritical CO2 extraction technology can extract the effective components of hops α-acid, β-acid and hop oil into a concentrated 5-10 times hop extract.

Supercritical CO2 Extraction of Vegetable Oils/Dietary Supplement Edible Oil

The application of supercritical CO2 fluid extraction to vegetable oils is relatively extensive and mature.

People have done a lot of research on soybeans, peanuts, sunflower seeds, palm seeds, rice bran, wheat germ, corn germ and other varieties. The content is low, the color is light, and the refining process such as vacuum distillation and deodorization can be omitted.

Compared with traditional methods, the residue after oil extraction still retains its original shape, which can be conveniently used to extract protein, blend into food or use as feed.

Therefore, supercritical CO2 fluid extraction technology is widely used in the development of health oils (Dietary supplement edible oil) with high added value, such as rice bran oil, wheat germ oil, sea buckthorn oil, etc., and has achieved industrial application results.

Supercritical CO2 Extraction of Natural Food Coloring

Compared with the traditional organic reagent method, the supercritical CO2 fluid extraction technology has no solvent residues and no pollution. It can avoid the thermal degradation of the extract at high temperature, protect the activity of physiologically active substances, and can maintain Examples include the natural flavor of the extract.

Therefore, the supercritical CO2 fluid extraction technology has been applied to the extraction and purification of natural food colorings such as capsicum red pigment, lycopene, β-carotene and gardenia yellow.

Supercritical CO2 Extraction of Natural Fragrances

In the traditional extraction method of natural flavor, it is still an inevitable processing method that the flavor components are subjected to heat treatment.

Such as water vapor distillation and solvent extraction heating may cause some heat-sensitive or chemically unstable components in natural spices to be destroyed, thus changing the unique aroma and flavor of natural spices.

The supercritical CO2 fluid extraction method can carry out the entire separation process at room temperature, and the CO2 is non-toxic and has no residual phenomenon, so it is particularly suitable for the separation and purification of unstable natural products and physiologically active substances, which is suitable for production closer to natural fragrance. The trend of spice processing products.

The supercritical CO2 fluid extraction method has attracted much attention because of the possibility of preparing almost perfect “natural” fragrances. It has become one of the most effective technological methods to obtain high-quality essential oil products.
