Supercritical CO2 extraction isolates nutraceuticals at low temperatures using CO2 above its critical point.
Origin: Japanese and German (1980s) — Japan, Germany
See full technique reference →CO2 above 31 °C and 73.8 bar behaves as a supercritical fluid with gas‑like diffusivity and liquid‑like solvating power. By adjusting pressure, temperature, and co‑solvent composition, selective extraction of non‑polar and polar bioactives is achieved while preserving thermolabile compounds.
Primary Reaction
CO2 dissolves target compounds in the matrix; upon depressurization, CO2 evaporates, leaving extracted nutraceuticals.
