Precipitation of Protein Powders by Gas Anti-Solvent (GAS)

SCF 527 Precipitation of Protein Powders into a Compressed Antisolvent lyophilization, and using miscible organic antisolvents. Unfortunately, these processes can also inactivate or denature proteins, produce small final yields, lead to electrostatically charged powders, produce particles with a broad distribution,…

SFC 526 The Micronization of Drug Particles by the Rapid Expansion of a Supercritical Solution precipitation of the solute as a powder in a gas phase. The result of the process is the formation of fine particles with a narrow…

SCF 530 CO2 allows the additives dissolved in the CO2 to be absorbed by the polyimide. Drying of Aerogels with Supercritical Carbon Dioxide As the system is rapidly depressurized, the CO2 is released and the precipitated additive is left in…

SCF 533 Selective Extraction of Fatty Acids and Carotenoids from Microalgae Introduction Spirulina maxima, a type of microalgae, is of great interest to the cosmetic, food, and pharmaceutical industries due to its chemical composition. The blue-green cyanobacterium is a source…
