1. Food industry

Oil extraction: Supercritical extraction technology can efficiently extract oil from various plants such as sunflower seeds, safflower seeds, peanuts, wheat germ, palm, cocoa beans, etc. The resulting oil has excellent quality, with high neutral lipid content, low phosphorus content, low coloring degree, no odor, and no solvent separation problem. Decaffeination and Nicotine Removal: Decaffeination can be applied to coffee beans and nicotine removal can be performed on tobacco. This technology can effectively remove harmful substances while retaining aromatic substances in coffee and tobacco.

Spice extraction: used to extract natural spices from plants such as basil, saffron, thyme, garlic, onion, chili, licorice, fennel, etc. The extracts have natural antibacterial or antioxidant properties and can be used for food seasoning and preservation.

Pigment Separation: It can separate natural colorants, such as extracting lycopene from tomato skins and purifying capsaicin from chili peppers!, Given the increasing concern for the safety of Taiwanese pigments, the application prospects of supercritical extraction of natural pigments are broad.

2. Pharmaceutical industry

Extraction of effective ingredients from Chinese herbal medicine: It can extract various effective ingredients from Chinese herbal medicine, such as ginsenosides, paclitaxel, ginkgo flavonoids, etc., to avoid the dispersion and oxidation of effective components in Chinese herbal medicine, improve the utilization rate of medicinal theft sources, and simplify the extraction and separation steps.

Heat sensitive biological product drug refining: suitable for refining highly heat sensitive biological product drugs such as proteins and enzymes. Operating at lower temperatures can prevent drug deterioration. Separation of lipid mixtures: used to separate polyunsaturated fatty acids (DHA, EPA) in fish oil and lipid mixtures such as phospholipids in egg yolks. These ingredients have unique therapeutic effects on cardiovascular and cerebrovascular diseases.

Antibiotic drug production: It can replace traditional organic solvents in antibiotic drug production, avoid solvent residue problems, and ensure drug quality.

3. Spice industry

Purification and refinement of natural spices to improve their purity and quality; It can also be used for the separation and purification of synthetic fragrances, obtaining high-purity fragrance products.

4. Chemical industry

Mixture separation: It can separate and purify chemical raw materials such as olefins, aromatics, alcohols, etc. Compared with traditional distillation and distillation techniques, polymerization reactions have advantages such as high efficiency, environmental friendliness, and mild conditions. Supercritical fluids can be used as reaction media or solvents in polymerization reactions. For example, heterogeneous polymerization is used when hydrocarbon polymers are insoluble in carbon dioxide, while homogeneous polymerization can be used when non mobile fluorocarbon polymers and silicone polymers are soluble in carbon dioxide.

5. Environmental protection industry

It can extract heavy metal ions, organic pollutants and other pollutants from water or soil, separate and recycle them, and achieve the resource utilization and harmless treatment of waste.

6. Agricultural field

·Extraction of plant active ingredients: used to extract essential oils, pigments and other active ingredients from plants, which can be applied in cosmetics, health products and other fields [13] Pesticide residue detection: assists in pesticide residue detection, providing assurance for the quality and safety of agricultural products,

Agricultural waste treatment: Processing agricultural waste, extracting useful components, and achieving resource reuse,

7. Biotechnology field

Extracting cellular metabolites: It can extract metabolites such as antibiotics, amino acids, vitamins, etc. during cell culture, providing raw materials for biopharmaceuticals.

Extracting proteins and enzymes: It can extract biological products such as proteins and enzymes, maintain their biological activity, and provide support for biotechnology research and application.
