Supercritical Fluid Extraction: A New Method for Extracting Biomass Substances

Supercritical fluid extraction (SFE) is a novel method that has emerged in recent years for extracting valuable substances from biomass materials. This method utilizes a fluid that exists in a supercritical state at high pressure and temperature, and can effectively extract substances that are difficult to extract using traditional solvents. Compared with traditional solvent-based extraction methods, SFE has the advantages of being environmentally friendly, efficient, and safe. It can be used to extract a wide range of substances, including pharmaceuticals, nutraceuticals, and other valuable substances from biomass materials, making it an important tool in the field of biotechnology and sustainable development.
