Frequently Asked Questions
Supercritical fluid extraction (SFE) is a process that uses supercritical fluids to separate components from a mixture. A fluid becomes "supercritical" when it is subjected to temperatures and pressures above its critical point, where it exhibits both liquid and gas properties. This state enables efficient extraction of desired compounds.
Supercritical CO2 extraction uses carbon dioxide as the supercritical fluid. At specific pressure and temperature conditions, CO2 becomes supercritical and acts as a solvent to extract compounds such as oils, flavors, and bioactive components from raw materials.
CO2 is widely used because it is safe, non-toxic, non-flammable, environmentally friendly, and readily available. It also allows for low-temperature extractions, preserving the quality and integrity of heat-sensitive compounds.
- High purity of the final product.
- Retention of sensitive nutrients and compounds due to low operating temperatures.
- Solvent-free extraction, ensuring no residual solvents in the final product.
- Environmentally friendly and sustainable.
Supercritical CO2 extraction is used to produce essential oils, plant extracts, flavors, fragrances, pharmaceutical compounds, and food additives. It is also popular in the cosmetic and nutraceutical industries.
Yes, the process is safe. CO2 is a non-toxic and inert gas. Moreover, the method avoids the use of harmful solvents, making it safer for both the producers and the consumers.
Unlike traditional solvent-based or heat-based methods, supercritical CO2 extraction uses no harmful chemicals and operates at relatively low temperatures. This preserves the natural qualities of the extracted compounds and ensures a cleaner and more sustainable process.
Supercritical CO2 extraction is environmentally friendly. CO2 used in the process is often recycled and does not generate harmful waste. It also eliminates the need for hazardous organic solvents, reducing environmental risks.
Yes, it is highly suitable. The absence of harmful chemicals and the ability to preserve the natural properties of raw materials make it ideal for organic and natural product lines.
The method preserves the essential oils' natural aroma, flavor, and bioactive compounds by avoiding high temperatures and chemical solvents. This results in a purer, more potent, and higher-quality oil compared to other extraction methods.
