TechnologyShowdown: Process Fundamentals
CO2 Supercritical Extraction
Operating at critical parameters (31°C/73bar), our GMP-certified CO2 systems achieve 98% solvent-free purity bymodulating density-tuned selectivity. Ideal for thermolabile compounds like rosemarycarnosic acid and ginger shogaols, CO2 preserves volatile terpenes lost inconventional methods – evidenced by 37% higher sesquiterpene retention in turmericessential oil versus ethanol.
Ethanol Hydrodynamic Extraction
Our patented low-temperature ethanol reflux(45°C) combines polarity advantages with reduced degradation. Modified with 8%water co-solvent, it outperforms CO2 for polar glycosides – yielding 12% higherginsenoside Rb1 recovery from Panax quinquefolius roots. Energy recoveryturbines cut steam consumption by 28% versus standard systems.
