Supercritical CO2 extraction technology has revolutionized the natural extracts industry by offering a cleaner, more efficient, and environmentally friendly method to obtain high-quality botanical extracts. Portugal, with its growing industrial base and commitment to sustainability, has become a promising hub for supercritical CO2 extracts manufacturing. This article explores the top supercritical CO2 extracts manufacturers in Portugal, their technologies, applications, and the benefits of this advanced extraction method.
What is Supercritical CO2 Extraction?
Supercritical CO2 extraction uses carbon dioxide above its critical temperature (31.1°C) and pressure (73.8 atm) to create a supercritical fluid that exhibits properties of both a gas and a liquid. This unique state allows CO2 to penetrate plant materials like a gas while dissolving compounds like a liquid, making it an excellent solvent for extracting oils, flavors, and active ingredients from natural products.
The process involves loading ground plant material into an extraction vessel, pumping pressurized CO2 through it, and then depressurizing to separate the extract from the CO2, which is recycled in a closed-loop system. This method produces solvent-free, pure extracts while preserving delicate bioactive compounds due to mild operating temperatures.
Why Choose Supercritical CO2 Extraction?
- Purity and Safety: Extracts are free from solvent residues, ensuring high purity and safety for pharmaceutical, food, and cosmetic applications.
- Environmental Sustainability: CO2 is non-toxic, non-flammable, recyclable, and reduces hazardous solvent waste, aligning with eco-conscious manufacturing practices.
- Efficiency: Extraction is faster and requires significantly less solvent than traditional methods, reducing costs and processing times.
- Selective Extraction: Adjustable pressure and temperature allow selective targeting of compounds, improving yield and quality.
- Preservation of Bioactives: Mild temperatures prevent degradation of sensitive compounds such as flavonoids, alkaloids, and essential oils.
